Letsencrypt Letsencrypt Free SSL certificates with web root authentication method

Update: September 2016 - below guide is no longer valid as Centmin Mod 123.09beta01 has a new addons/acmetool.sh integration outlined at Letsencrypt - Official acmetool.sh testing thread for Centmin Mod 123.09beta01 | Centmin Mod Community

Letsencrypt plugin, simplefs authentication has been renamed web root authentication - named by yours truly Let's test Letsencrypt webroot authentication branch fork/branch SimpleFS plugin (fixes #742) by kuba · Pull Request #757 · letsencrypt/letsencrypt · GitHub. There's also an example for Debian Jessie + Apache.

Update

You can jump straight to actual Centmin Mod LEMP integration tests here in this thread.

Manual Letsencrypt Install

Note Letsencrypt client removed Python 2.6 support so you need Python 2.7. For CentOS 6.x folks you have Python 2.6 so need to install Python 2.7 via Centmin Mod Addon. For CentOS 7.x folks you have Python 2.7 out of box so no need.

Updated Oct 24th, 2015 instructions

For CentOS 7.x run

Code:

mkdir -p /root/tools
cd /root/tools
rm -rf /root/tools/letsencrypt
rm -rf /etc/letsencrypt
rm -rf /var/lib/letsencrypt
rm -rf /root/.local/share
git clone https://github.com/letsencrypt/letsencrypt
cd letsencrypt
./letsencrypt-auto --verbose

For CentOS 6.x after install Python 2.7, run (note sed replacement to switch to python2.7 instead of python 2 due to letsencrypt-auto doesn't work with Python 2.6 · Issue #1046 · letsencrypt/letsencrypt · GitHub

Code:

mkdir -p /root/tools
cd /root/tools
rm -rf /root/tools/letsencrypt
rm -rf /etc/letsencrypt
rm -rf /var/lib/letsencrypt
rm -rf /root/.local/share
git clone https://github.com/letsencrypt/letsencrypt
cd letsencrypt
sed -i "s|--python python2|--python python2.7|" letsencrypt-auto
./letsencrypt-auto --verbose

For CentOS 7.x run

Code:

mkdir -p /root/tools
cd /root/tools
rm -rf /root/tools/letsencrypt
rm -rf /etc/letsencrypt
rm -rf /var/lib/letsencrypt
git clone https://github.com/letsencrypt/letsencrypt

cd letsencrypt
./bootstrap/centos.sh
virtualenv --no-site-packages -p python2 venv
./venv/bin/pip install -r requirements.txt acme/ . letsencrypt-apache/ letsencrypt-nginx/

For CentOS 6.x after install Python 2.7, run

Code:

mkdir -p /root/tools
cd /root/tools
rm -rf /root/tools/letsencrypt
rm -rf /etc/letsencrypt
rm -rf /var/lib/letsencrypt
git clone https://github.com/letsencrypt/letsencrypt
#git clone -b simplefs https://github.com/kuba/letsencrypt
cd letsencrypt
./bootstrap/centos.sh
virtualenv --no-site-packages -p python2.7 venv
./venv/bin/pip install -r requirements.txt acme/ . letsencrypt-apache/ letsencrypt-nginx/

CentOS 6.7 with Centmin Mod stack and Python addons installed

Code:

python --version
Python 2.6.6

python2.7 --version
Python 2.7.10

python3.4 --version
Python 3.4.3

For centminmod.com LEMP stack Nginx server I setup for dedicated Letsencrypt testing, I need to remove existing nginx vhost account and re-setup via nginx vhost auto generator. I am using domain = le1.http2ssl.xyz for testing.

Code:

vhostname='le1.http2ssl.xyz'
rm -rf /usr/local/nginx/conf/conf.d/${vhostname}.conf
rm -rf /usr/local/nginx/conf/conf.d/${vhostname}.ssl.conf
rm -rf /usr/local/nginx/conf/ssl/${vhostname}/${vhostname}.crt
rm -rf /usr/local/nginx/conf/ssl/${vhostname}/${vhostname}.key
rm -rf /usr/local/nginx/conf/ssl/${vhostname}/${vhostname}.csr
rm -rf /usr/local/nginx/conf/ssl/${vhostname}
rm -rf /home/nginx/domains/${vhostname}
ngxrestart

for my own records i have several domains setup for testing so need to wipe those too

Code:

vhostname='le1.http2ssl.xyz le2.http2ssl.xyz le3.http2ssl.xyz le4.http2ssl.xyz le5.http2ssl.xyz le6.http2ssl.xyz le7.http2ssl.xyz le8.http2ssl.xyz le9.http2ssl.xyz'
for v in $vhostname; do
rm -rf /usr/local/nginx/conf/conf.d/${v}.conf
rm -rf /usr/local/nginx/conf/conf.d/${v}.ssl.conf
rm -rf /usr/local/nginx/conf/ssl/${v}/${v}.crt
rm -rf /usr/local/nginx/conf/ssl/${v}/${v}.key
rm -rf /usr/local/nginx/conf/ssl/${v}/${v}.csr
rm -rf /usr/local/nginx/conf/ssl/${v}
rm -rf /home/nginx/domains/${v}
done
ngxrestart

re-create the nginx vhost on centminmod.com LEMP stack via command line Nginx vhost generator with self-signed ssl certificate and nginx ssl vhost auto generated with pure-ftpd username myftpuser001

Code:

vhostname='le1.http2ssl.xyz'
nv -d ${vhostname} -s y -u myftpuser001

output from auto generated nginx vhost with both http and https self-signed ssl vhost config files auto created

Code:

upload files to /home/nginx/domains/le1.http2ssl.xyz/public
vhost log files directory is /home/nginx/domains/le1.http2ssl.xyz/log

the resulting Nginx vhost config files and directories that are auto generated include the Nginx HTTP/2 SSL vhost configuration file setup. Also the letsencrypt required .well-known url with application/jose+json content type header is already taken care of as the header is added into an auto included nginx file.

Code:

location ~ /.well-known {
      location ~ /.well-known/acme-challenge/(.*) {
              more_set_headers    "Content-Type: application/jose+json";
      }
}

run the letsencrypt client in web root authentication mode passing the auto generated Centmin Mod Nginx vhost's web root path /home/nginx/domains/le1.http2ssl.xyz/public to the --web-root flag

Update: October 24th, path to letsencrypt binary has changed from /root/tools/letsencrypt/venv/bin/letsencrypt to /root/.local/share/letsencrypt/bin/letsencrypt and options have been removed for --agree-eula

Code:

vhostname='le1.http2ssl.xyz'
/root/.local/share/letsencrypt/bin/letsencrypt --renew-by-default -a webroot --webroot-path /home/nginx/domains/${vhostname}/public --email example@example.org --text --agree-tos --agree-dev-preview -d ${vhostname} auth

Look's like Python 2.6 is no longer supported by Letsencrypt client Python 2.6 support removed - Issuance Tech Questions - Let's Encrypt Community Support so if you run CentOS 6.x you will have problems as default Python 2.6.6 is installed whereas CentOS 7.x has Python 2.7.

Code:

/root/tools/letsencrypt/venv/lib/python2.6/site-packages/cryptography/__init__.py:25: DeprecationWarning: Python 2.6 is no longer supported by the Python core team, please upgrade your Python.
  DeprecationWarning
An unexpected error occurred.
TypeError: super() argument 1 must be type, not classobj
Please see the logfile 'letsencrypt.log' for more details.

You need to install Python 2.7 side by side on CentOS 6 so Centmin Mod LEMP stack has an addon to install Python 2.7 or Python 3.4 in addons/ folder of your Centmin Mod install directory.

Code:

ls -lah /usr/local/src/centminmod/addons/
total 112K
drwxr-xr-x  2 root root 4.0K Oct  5 12:54 .
drwxr-xr-x 14 root root 4.0K Oct  5 12:54 ..

-rwxr-xr-x  1 root root 4.2K Aug 30 13:59 wpcli.sh

So run python27_install.sh addon to install python 2.7 side by side with CentOS 6.x's Python 2.6 via IUS Community repo which is backed by Rackspace.com

Then wipe Letsencrypt install and install again this time with Python virtual environment setup for Python 2.7

For CentOS 6.x after install Python 2.7, run (note sed replacement to switch to python2.7 instead of python 2 due to letsencrypt-auto doesn't work with Python 2.6 · Issue #1046 · letsencrypt/letsencrypt · GitHub

Code:

mkdir -p /root/tools
cd /root/tools
rm -rf /root/tools/letsencrypt
rm -rf /etc/letsencrypt
rm -rf /var/lib/letsencrypt
rm -rf /root/.local/share
git clone https://github.com/letsencrypt/letsencrypt
cd letsencrypt
sed -i "s|--python python2|--python python2.7|" letsencrypt-auto
./letsencrypt-auto --verbose

Run Letsencrypt web root authentication again and now works with Python 2.7

IMPORTANT NOTES:
- If you lose your account credentials, you can recover through
   e-mails sent to example@example.org.
- Congratulations! Your certificate has been saved at
   /etc/letsencrypt/live/le1.http2ssl.xyz/cert.pem.
- Your account credentials have been saved in your Let's Encrypt
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Let's
   Encrypt so making regular backups of this folder is ideal.
- Automatic renewal and deployment has been enabled for your
   certificate. These settings can be configured in the directories
   under /etc/letsencrypt/renewal.

Yay free SSL certificate obtained.

Backup /etc/letsencrypt

Code:

cp -a /etc/letsencrypt /etc/letsencrypt-bak

Now to put Letsencrypt SSL certificate into Centmin Mod Nginx's auto generated SSL vhost. Using sed replacement for the default auto generated self-signed SSL certificate paths with Letsencrypt's obtained SSL certificates. Once web root authentication plugin is officially merged into master code, I'll automate this step too as part of Centmin Mod Nginx vhost setup routine

Code:

vhostname='le1.http2ssl.xyz'
sed -i "s|\/usr\/local\/nginx\/conf\/ssl\/${vhostname}\/${vhostname}.crt|\/etc\/letsencrypt\/live\/${vhostname}\/fullchain.pem|" /usr/local/nginx/conf/conf.d/${vhostname}.ssl.conf
sed -i "s|\/usr\/local\/nginx\/conf\/ssl\/${vhostname}\/${vhostname}.key|\/etc\/letsencrypt\/live\/${vhostname}\/privkey.pem|" /usr/local/nginx/conf/conf.d/${vhostname}.ssl.conf

End result for the SSL vhost at /usr/local/nginx/conf/conf.d/le1.http2ssl.xyz.ssl.conf partial contents now looks like

Code:

server {
  listen 443 ssl http2;
  server_name le1.http2ssl.xyz www.le1.http2ssl.xyz;

  ssl_dhparam /usr/local/nginx/conf/ssl/le1.http2ssl.xyz/dhparam.pem;

Good news on 2 fronts

1. Letsencrypt is re-introducing Python 2.6 and 3.3 support instead of Python 2.7 only Python 2.6 and 3.3+ support by kuba · Pull Request #957 · letsencrypt/letsencrypt · GitHub This will be merged into their code at GA release time not before though. So for beta testing and pre-GA testing still need Python 2.7 to play with Letsencrypt

2. Letsencrypt web root authentication plugin outlined above is closer to merge into official code i think SimpleFS plugin (fixes #742) by kuba · Pull Request #757 · letsencrypt/letsencrypt · GitHub - fingers crossed

 

FYI Letsencrypt web root authentication plugin outlined above has been officially merged into master code now --webroot-root -> --webroot-path · letsencrypt/letsencrypt@63c080b · GitHub

at plugins/webroot.py letsencrypt/letsencrypt/plugins at master · letsencrypt/letsencrypt · GitHub

 

Letsencrypt is now official cross-signed too Let's Encrypt is Trusted

My definition of what Letsencrypt Webroot Authentication is:

See examples of webroot authentication plugin at Using the webroot domain verification method - Server Configuration - Let's Encrypt Community Support and SSL - Letsencrypt Free SSL certificates with web root authentication method

official definition

It was born out of the simplefs plugin SimpleFS plugin (fixes #742) by kuba · Pull Request #757 · letsencrypt/letsencrypt · GitHub which was later renamed to webroot authentication. In laymen terms, webroot authentication is an alternate way to obtain letsencrypt ssl certificates and pass the SimpleHTTP challenge by following these steps

1. create a HTTPS base site before hand using self signed ssl certificate on apache or nginx - this site will have a public web root. This site domain also needs valid working DNS pointing to the server IP
2. run letsencrypt webroot authentication method and pass your email address AND that site's public web root path to the command you run - this will perform automatically the the .well-known uri creation on the defined web root validating the domain you want the ssl certificate for

 

Yay got my Letsencrypt beta invite approval email so the domains I requested have been whitelisted for full web browser trusted SSL certificates

Below are steps I used for Centmin Mod LEMP Nginx server + how I setup Letsencrypt Client for beta testing with fully web browser trusted Letsencrypt SSL certificate.

First clear the previous code and install fresh the Letsencrypt client on CentOS 6.x, I need to separately install Python 2.7 and then sed replace python2 with python2.7 in letsencrypt-auto

Code:

mkdir -p /root/tools
cd /root/tools
rm -rf /root/tools/letsencrypt
rm -rf /etc/letsencrypt
rm -rf /var/lib/letsencrypt
rm -rf /root/.local/share
git clone https://github.com/letsencrypt/letsencrypt
cd letsencrypt
sed -i "s|--python python2|--python python2.7|" letsencrypt-auto
./letsencrypt-auto --agree-dev-preview --server https://acme-v01.api.letsencrypt.org/directory

Then setup Centmin Mod Nginx vhost for le1.http2ssl.xyz domain which is one of the Letsencrypt whitelisted domains. This will auto generate the self signed SSL nginx vhost before hand making it easy to use Letsencrypt webroot authentication method to obtain the Letsencrypt browser trusted SSL certificate

Code:

vhostname='le1.http2ssl.xyz'
nv -d ${vhostname} -s y -u MYFTPUSERNAME

Now run Letsencrypt webroot authentication method to obtain the Letsencrypt browser trusted SSL certificate, changing example@example.org to your own email address and being sure to pass the -a webroot --webroot-path /home/nginx/domains/${vhostname}/public variables for Nginx vhost's web root.

Code:

vhostname='le1.http2ssl.xyz'
/root/.local/share/letsencrypt/bin/letsencrypt --server https://acme-v01.api.letsencrypt.org/directory --renew-by-default -a webroot --webroot-path /home/nginx/domains/${vhostname}/public --email example@example.org --text --agree-tos --agree-dev-preview -d ${vhostname} auth

Once Letsencrypt webroot authentication is completed, you will get the following message including the path to your Letsencrypt SSL certificate at /etc/letsencrypt/live/le1.http2ssl.xyz/fullchain.pem

Code:

IMPORTANT NOTES:
- If you lose your account credentials, you can recover through
   e-mails sent to example@example.org.
- Congratulations! Your certificate and chain have been saved at
   /etc/letsencrypt/live/le1.http2ssl.xyz/fullchain.pem. Your cert
   will expire on 2016-01-25. To obtain a new version of the
   certificate in the future, simply run Let's Encrypt again.
- Your account credentials have been saved in your Let's Encrypt
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Let's
   Encrypt so making regular backups of this folder is ideal.

replace nginx SSL vhost's (/usr/local/nginx/conf/conf.d/${vhostname}.ssl.conf) self signed SSL certificate that was auto generated with Letsencrypt's obtained SSL certificate and restart Nginx server

Code:

vhostname='le1.http2ssl.xyz'
sed -i "s|\/usr\/local\/nginx\/conf\/ssl\/${vhostname}\/${vhostname}.crt|\/etc\/letsencrypt\/live\/${vhostname}\/fullchain.pem|" /usr/local/nginx/conf/conf.d/${vhostname}.ssl.conf
sed -i "s|\/usr\/local\/nginx\/conf\/ssl\/${vhostname}\/${vhostname}.key|\/etc\/letsencrypt\/live\/${vhostname}\/privkey.pem|" /usr/local/nginx/conf/conf.d/${vhostname}.ssl.conf
ngxrestart

as this is a fully trusted SSL certificate, a few more sed replacements needed to enable ssl_stapling, ssl_stapling_verify and ssl_trusted_certificate settings in nginx SSL vhost /usr/local/nginx/conf/conf.d/${vhostname}.ssl.conf

Code:

sed -i "s|#resolver |resolver |" /usr/local/nginx/conf/conf.d/${vhostname}.ssl.conf
sed -i "s|#resolver_timeout|resolver_timeout|" /usr/local/nginx/conf/conf.d/${vhostname}.ssl.conf
sed -i "s|#ssl_stapling on|ssl_stapling on|" /usr/local/nginx/conf/conf.d/${vhostname}.ssl.conf
sed -i "s|#ssl_stapling_verify|ssl_stapling_verify|" /usr/local/nginx/conf/conf.d/${vhostname}.ssl.conf
sed -i "s|#ssl_trusted_certificate|ssl_trusted_certificate|" /usr/local/nginx/conf/conf.d/${vhostname}.ssl.conf
sed -i "s|\/usr\/local\/nginx\/conf\/ssl\/${vhostname}\/${vhostname}-trusted.crt|\/etc\/letsencrypt\/live\/${vhostname}\/fullchain.pem|" /usr/local/nginx/conf/conf.d/${vhostname}.ssl.conf
nprestart

so changes in nginx SSL vhost /usr/local/nginx/conf/conf.d/${vhostname}.ssl.conf from

Code:

  #resolver 8.8.8.8 8.8.4.4 valid=10m;
  #resolver_timeout 10s;
  #ssl_stapling on;
  #ssl_stapling_verify on;
  #ssl_trusted_certificate /usr/local/nginx/conf/ssl/le1.http2ssl.xyz/le1.http2ssl.xyz-trusted.crt; 

to

Code:

  resolver 8.8.8.8 8.8.4.4 valid=10m;
  resolver_timeout 10s;
  ssl_stapling on;
  ssl_stapling_verify on;
  ssl_trusted_certificate /etc/letsencrypt/live/le1.http2ssl.xyz/fullchain.pem;

Multi Domain SAN SSL with Letsencrypt Webroot Authentication

Using Letsencrypt webroot authentication plugin client to setup a multi domain SAN based SSL certificate for le8.http2ssl.xyz and le9.http2ssl.xyz on Centminmod.com LEMP web stack's Nginx server. Method was first outlined here and as Centmin Mod stack already has a default_server listen vhost for main virtual.conf, it was easy to setup. Some minor improvements suggested at multi domain SAN SSL symlink directories ? · Issue #1260 · letsencrypt/letsencrypt · GitHub

Step 1. Make sure DNS A records for le8.http2ssl.xyz and le9.http2ssl.xyz point to the same server IP

Step 2. Auto generate the nginx http and https vhosts for le8.http2ssl.xyz and le9.http2ssl.xyz

Code:

nv -d le8.http2ssl.xyz -s y -u le8ahewf

Code:

nv -d le9.http2ssl.xyz -s y -u le9shxkf

Step 3. Create a /etc/letsencrypt/sancli.ini config file User Guide — Let's Encrypt 0.1.0.dev0 documentation used only for SAN based SSL certificates for webroot authentication. Make sure to edit the email address to your email you want to register with Letsencrypt. Then decide if you're using staging server https://acme-staging.api.letsencrypt.org/directory or the beta/live server https://acme-v01.api.letsencrypt.org/directory.

contents of sancli.ini

Code:

# This is sancli.ini for centminmod.com LEMP stack to support webroot authentication
# with multi domain SAN SSL certificates where webroot-path defaults to /usr/local/nginx/html
# which already has a main vhost setup at /usr/local/nginx/conf/conf.d/virtual.conf with
# default_server listen directive enabled and the virtual.conf include
# /usr/local/nginx/conf/staticfiles.conf already supports LE .well-known uri files

# Use a 4096 bit RSA key instead of 2048
rsa-key-size = 2048

# Always use the staging/testing server
# server = https://acme-staging.api.letsencrypt.org/directory
# for beta invitees
server = https://acme-v01.api.letsencrypt.org/directory

# Uncomment and update to register with the specified e-mail address
email = foo@example.com

# Uncomment to use a text interface instead of ncurses
text = True
agree-tos = True
agree-dev-preview = True
renew-by-default = True

# Uncomment to use the webroot authenticator. Replace webroot-path with the
# path to the public_html / webroot folder being served by your web server.
authenticator = webroot
webroot-path = /usr/local/nginx/html

Step 4. Run Letsencrypt webroot authentication plugin client to obtain a multi domain SAN based SSL certificate for le8.http2ssl.xyz and le9.http2ssl.xyz

temporarily rename the http vhost files for the 2 domains so that the domains when doing simpleHttp challenge response the web root used goes the virtual.conf set default_server

Code:

mv /usr/local/nginx/conf/conf.d/le8.http2ssl.xyz.conf /usr/local/nginx/conf/conf.d/le8.http2ssl.xyz.conf.disable
mv /usr/local/nginx/conf/conf.d/le9.http2ssl.xyz.conf /usr/local/nginx/conf/conf.d/le9.http2ssl.xyz.conf.disable
nprestart

Then run webroot authentication passing the config file sancli.ini created in step 3

Code:

/root/.local/share/letsencrypt/bin/letsencrypt -c sancli.ini -d le8.http2ssl.xyz -d le9.http2ssl.xyz auth

Output if successful

Code:

IMPORTANT NOTES:
- Congratulations! Your certificate and chain have been saved at
   /etc/letsencrypt/live/le8.http2ssl.xyz/fullchain.pem. Your cert
   will expire on 2016-01-29. To obtain a new version of the
   certificate in the future, simply run Let's Encrypt again.

Step 5. Replace step 2 generated self signed SSL certificates with Letsencrypt obtained multi domain SAN SSL certificate and rename back the vhost conf files done in step 4

Code:

mv /usr/local/nginx/conf/conf.d/le8.http2ssl.xyz.conf.disable /usr/local/nginx/conf/conf.d/le8.http2ssl.xyz.conf
mv /usr/local/nginx/conf/conf.d/le9.http2ssl.xyz.conf.disable /usr/local/nginx/conf/conf.d/le9.http2ssl.xyz.conf

for 2nd and subsequent vhosts in multi domain SAN, the path to the SSL certificate is actually the same as your very first domain setup so for le9.http2ssl.xyz it's not path at /etc/letsencrypt/live/le9.http2ssl.xyz but at /etc/letsencrypt/live/le8.http2ssl.xyz. So need one more sed replacement for /usr/local/nginx/conf/conf.d/le9.http2ssl.xyz.ssl.conf

Code:

vhostname='le9.http2ssl.xyz'
sed -i "s|\/etc\/letsencrypt\/live\/le9.http2ssl.xyz|\/etc\/letsencrypt\/live\/le8.http2ssl.xyz|g" /usr/local/nginx/conf/conf.d/${vhostname}.ssl.conf
nprestart

End result is multi domain SAN based SSL certificate from Letsencrypt

FYI, in last 24hrs there's been major changes to how Letsencrypt validates domains in terms of the expected content-type response that is returned.

The changes outlined at

• Using the webroot domain verification method - Server Configuration - Let's Encrypt Community Support
• Using the webroot domain verification method - Server Configuration - Let's Encrypt Community Support

This will require an update on Centmin Mod code side to support the changes as well once I figure it all out. So whenever, the code is updated on Centmin Mod end, you'd need to update Centmin Mod first.

To update your Centmin Mod builds follow instructions at centminmod.com/upgrade.html and respective version threads below:

• Centmin Mod 1.2.3-eva2000.08 stable install & update thread
• Centmin Mod 123.09beta thread

Using dummy domain = domain1.com for new Nginx vhost for testing so there will be no valid DNS A record. Letsencrypt SSL relies on self-signed SSL setup prior, so answered yes when prompted. If you answer yes to Letsencrypt SSL, it will auto set self signed SSL certificate vhost routine to yes too anyway.

This is example of aborting Nginx vhost setup at prompt, allowing end user time to update their intended domain's DNS A record first

Code:

---------------------------------------------
Enter vhost domain name to add (without www. prefix): domain1.com

Create a self-signed SSL certificate Nginx vhost? [y/n]: y

To get Letsencrypt SSL certificate, you must already have updated intended
domain vhost name's DNS A record to this server's IP addresss otherwise
Letsencrypt domain name validation will fail.

current DNS A record IP address for domain1.com is:

Abort this Nginx vhost domain setup to setup proper DNS A record first? [y/n]: y

 

Centmin Mod 123.09beta01le Letsencrypt Test Part 2

This example is of Letsencrypt webroot authentication proceeding instead of aborting. The 1st time you run, you need to specify a valid email address to register a Letsencrypt account. This email address is auto populated in a created /etc/letsencrypt/webroot.ini config file Centmin Mod auto creates and used on Centmin Mod automation end only.

Letsencrypt client itself records this email address itself on ACME server remote end + locally according to Clarify purpose of --email · Issue #1310 · letsencrypt/letsencrypt · GitHub at

Code:

/etc/letsencrypt/accounts/<server_url>/directory/<hash>/regr.json

However, currently there is no way to update or change the registered email address that Letsencrypt account records initially see Clarify the --email flag requirements? - Issuance Tech Questions - Let's Encrypt Community Support and Allow contact information updates · Issue #30 · ietf-wg-acme/acme · GitHub Which could be problematic if end users want to update their email addresses and where Letsencrypt email notifications and auto renewal notifications are sent to ! So you better make sure the email address you use has a solid email service and uptime. It's why for Centmin Mod LEMP stacks I highly recommend more reliable 3rd party @yourdomain email providers instead of trying to host your email on the same server.

Unfortunately, Letsencrypt client won't be getting updated to support email registration changes at GA public release time Clarify the --email flag requirements? - Issuance Tech Questions - Let's Encrypt Community Support

The below example is of a failed registration, as I gave a dummy email address for testing.

Letsencrypt webroot authentication failed as the email address registered was invalid. As such the original self-signed SSL certificates created are left in place. I added an error detection routine, so that only when Letsencrypt webroot authentication succeeds, will the Letsencrypt obtained SSL certificates replace the ones contained in the https SSL nginx vhost at /usr/local/nginx/conf/conf.d/domain1.com.ssl.conf

Code:

setup general /etc/letsencrypt/webroot.ini letsencrypt config file

You only do this once, so that Letsencrypt can notify &
contact you via email regarding your SSL certificates

Email Address MX record check

Seems Letsencrypt client also checks if email address domain has MX records attached to them, so I updated Centmin Mod routine to check for it when you enter an email address so it fails earlier so you can correct it.

Now when you enter an email address and do not have an MX record on domain or if you have empty email address you will get an error and prompt to re-enter a valid email address

Code:

setup general /etc/letsencrypt/webroot.ini letsencrypt config file

Re-Enter your email address to setup Letsencrypt account:

!! Error: email address is empty

!! Error: email address is empty

Re-Enter your email address to setup Letsencrypt account:

If you enter a valid email address it will proceed with Letsencrypt account registration and you will get Notes notifying that your email address and Letsencrypt account has been setup and saved to /etc/letsencrypt.

Code:

Re-Enter your email address to setup Letsencrypt account: valid@validemailaddy.com

- If you lose your account credentials, you can recover through

However, error still exists for domain1.com as obviously domain1.com dummy domain has invalid DNS A record so failed Letsencrypt's domain validation when running webroot authentication.

Letsencrypt enters public beta December 3, 2015

 

Letsencrypt Webroot Authentication Plugin Integration - Live Run

Update: added official site page at http://centminmod.com/letsencrypt-freessl.html

The first test of beta invited whitelisted domain le10.http2ssl.xyz Nginx vhost creation routine with Letsencrypt free domain validated SSL certificate on Centmin Mod 123.09beta01le experimental branch which was forked from official 123.09beta01 branch. The latest code includes passing the --user-agent flag to Letsencrypt client for identification.

This is full run from start to finish via centmin.sh menu option 2 which is the only place currently were Letsencrypt client integration has been added (once menu option routine for LE is working fully, will add routines to /usr/bin/nv command line method of Nginx vhost auto generation ). The end result will be Nginx vhosts auto generated for both http and https sides of the web site with Letsencrypt domain validated SSL certificate in place on https side.

• vhost conf file for le10.http2ssl.xyz created: /usr/local/nginx/conf/conf.d/le10.http2ssl.xyz.conf

There's also a cronjob file setup on successfully obtaining Letsencrypt SSL certificate only at /usr/local/nginx/conf/ssl/le10.http2ssl.xyz/letsencrypt-le10.http2ssl.xyz-cron. Contents of /usr/local/nginx/conf/ssl/le10.http2ssl.xyz/letsencrypt-le10.http2ssl.xyz-cron

cronjob is auto setup to run every 2 months with random sleep interval set so if you have many nginx vhosts with Letsencrypt SSL certificates, cronjob auto renewals are not all run simultaneously

IMPORTANT NOTES:
- Congratulations! Your certificate and chain have been saved at
   /etc/letsencrypt/live/le10.http2ssl.xyz/fullchain.pem. Your cert
   will expire on 2016-02-13. To obtain a new version of the
   certificate in the future, simply run Let's Encrypt again.

Service Monitoring: crond

As crond service is critical for auto renewals, probably need to monitor and auto restart such services. I've been working on monit support for Centmin Mod and several dozen monit services' configuration profiles for ages now with CentOS 6 support - only started adding CentOS 7 support as well so to monitor and auto restart all Centmin Mod LEMP stack's services.

Then I deliberately stopped crond service so that monit can detect crond service as being down and auto restart it. The current default is to wait 120 seconds before reporting a service as being down and auto restart and send email notifications.

Code:

tail -50 /var/log/monit.log
[UTC Nov 16 20:17:21] info     : Generated unique Monit id 9a71505590331e4d3fb1558db4491b04 and stored to '/root/.monit.id'

[UTC Nov 16 20:23:00] info     : 'cron' trying to restart
[UTC Nov 16 20:23:00] info     : 'cron' start: /usr/bin/systemctl

Then checked crond service and see monit auto restarted the service

Code:

Working on a companion script to report every Letsencrypt SSL certificates' expiry dates in number of days

Code:

./expirydate.sh 

/etc/letsencrypt/live/le2.http2ssl.xyz/cert.pem
certificate expires in 74 days on 2 Feb 2016

/etc/letsencrypt/live/le8.http2ssl.xyz/cert.pem
certificate expires in 70 days on 29 Jan 2016

/etc/letsencrypt/live/le1.http2ssl.xyz/cert.pem
certificate expires in 66 days on 25 Jan 2016

/etc/letsencrypt/live/http2ssl.xyz/cert.pem
certificate expires in 66 days on 25 Jan 2016

 

Could be problematic that Letsencrypt client installed dependency requires quite a bit of system memory - not even 512MB VPS is working Running with 192MB RAM is not enough · Issue #1081 · letsencrypt/letsencrypt · GitHub Both my test VPSes for Letsencrypt are 1GB VPS so probably why I haven't run into this problem myself.

 

tools/nv.sh and /usr/bin/nv Letsencrypt integration

So far have been only working on shell based menu LE integration into centmin.sh menu option 2. Now that this is more polished, working on Letsencrypt integration into the command line version of Centmin Mod's auto generator for Nginx vhost domains - tools/nv.sh and /usr/bin/nv commands.

/usr/bin/nv command has added a new flag option for -s le specifically for auto generation of an Nginx vhost with Letsencrypt SSL certificates. If you use the regular -s y flag option it just auto generates Nginx vhost with self-signed SSL certificate instead.

Code:

nv -h

Usage: /usr/bin/nv [-d yourdomain.com] [-s y|n|le] [-u ftpusername]

  -d  yourdomain.com or subdomain.yourdomain.com
  -s  ssl self-signed create = y or n or le (for letsencrypt ssl certs)
  -u  your FTP username

  example:

  /usr/bin/nv -d yourdomain.com -s y -u ftpusername
  /usr/bin/nv -d yourdomain.com -s le -u ftpusername

Example run below is done in virtualbox test CentOS 7 server, so the final authorisation for Letsencrypt will fail as DNS A record for le11.http2ssl.xyz domain isn't pointing to my virtualbox server local IP.

Run nv command with -s le flag for Letsencrypt and pass pure-ftpd virtual ftp username you want to use for Nginx vhost domain.

Code:

nv -d le11.http2ssl.xyz -s le -u **********

Code:

nv -d le11.http2ssl.xyz -s le -u **********
---------------------------------------------------------------
Nginx Vhost Setup...
---------------------------------------------------------------


To get Letsencrypt SSL certificate, you must already have updated intended
domain vhost name's DNS A record to this server's IP addresss.
If top level domain, DNS A record is needed also for www. version of domain
otherwise, Letsencrypt domain name validation will fail.


le11.http2ssl.xyz is not a top level domain
your server IP address: *************
current DNS A record IP address for le11.http2ssl.xyz is: 104.152.214.220

Abort this Nginx vhost domain setup to setup proper DNS A record(s) first? [y/n]: n

IMPORTANT NOTES:
- If you lose your account credentials, you can recover through
   e-mails sent to validemail@addy.com.
- The following 'unauthorized' errors were reported by the server:

   Domains: le11.http2ssl.xyz
   Error: The client lacks sufficient authorization

   To fix these errors, please make sure that your domain name was
   entered correctly and the DNS A record(s) for that domain
   contain(s) the right IP address.
- Your account credentials have been saved in your Let's Encrypt
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Let's
   Encrypt so making regular backups of this folder is ideal.
