Cloudflare DNS Getting started with Cloudflare

Yeah you might not be able to use namecheap's free email forwarding with cloudflare dns. So might need to use proper @domain email 3rd party Email - Free @yourdomain.com Email Accounts & Alternatives

 

If you use a reverse proxy like Cloudflare in front of Centmin Mod Nginx, you need to setup nginx realip to be passed onto Nginx.

See Getting Started Guide step 5 and setting correct real ip via nginx module config at http://centminmod.com/nginx_configure_cloudflare.html.

If using Centmin Mod 123.09beta01 and newer, there's an added tools/csfcf.sh script to aid in this. Details at:

• Beta Branch - csfcf.sh - automate Cloudflare Nginx & CSF Firewall setups | Centmin Mod Community
• Beta Branch - add cloudflare.conf include file support | Centmin Mod Community

You just need to setup a cronjob to run

Code (Text):

/usr/local/src/centminmod/tools/csfcf.sh auto

and ensure your nginx.conf http{} context has the include file /usr/local/nginx/conf/cloudflare.conf and/or your individual nginx vhost's server contexts has the same include file
Then restart nginx server via command shortcut

Code (Text):

ngxrestart

or

Code (Text):

service nginx restart

 

yes for any domain behind needs realip setup

Adding additional IPs to a server involves 2 main tasks

1. Adding and registering additional IPs to system network configuration which Linode network helper would of done
2. Configuring Nginx to use those additional IPs which you need to do yourself

Configuring Nginx Additional IP Usage

Nginx can setup Vhosts to use either name based hosting (default) sharing the main IP address or IP based hosting where a Vhost uses a dedicated or different IP address for main IP address. This is controlled by Nginx listen directive How nginx processes a request

Centmin Mod 123.09beta01 and higher have native support to configure Nginx vhost creation routines to use a separate second IP from the main server IP address via persistent config file /etc/centminmod/custom_config.inc set variable called SECOND_IP discussed and added at Beta Branch - update nginx vhost generator routines support second IP

Support secondary dedicated IP configuration for centmin mod nginx vhost generator, so out of the box, new nginx vhosts generated will use the defined SECOND_IP=111.222.333.444 where the IP is a secondary IP addressed added to the server.

You define SECOND_IP variable is centmin mod persistent config file outlined at Upgrade Centmin Mod - CentminMod.com LEMP Nginx web stack for CentOS you manually create the file at /etc/centminmod/custom_config.inc and add SECOND_IP=yoursecondary_IPaddress variable to it which will be registered with nginx vhost generator routine so that any new nginx vhosts created via centmin.sh menu option 2 or /usr/bin/nv or centmin.sh menu option 22, will have pre-defined SECOND_IP ip address set in the nginx vhost's listen directive.

So in persistent config file you create or already created at /etc/centminmod/custom_config.inc set in it

Code (Text):

SECOND_IP=111.222.333.444

Only set SECOND_IP in /etc/centminmod/custom_config.inc if you want future nginx vhosts created listening on the 2nd IP instead primary main IP.

So at centmin.sh menu option 2, 22 or nv command runs to create a fresh new Nginx vhost instead of server{} context's listen directive being listed as

Code (Text):

listen 80;

with SECOND_IP set it will become

Code (Text):

listen 111.222.333.444:80;

for HTTPS on port 443

instead of

Code (Text):

listen 443;

with SECOND_IP set it will become

Code (Text):

listen 111.222.333.444:443;

where you defined SECOND_IP=111.222.333.444

Thus allowing you to use a different server IP for new nginx vhosts generated automatically.

Now if you want to use a different IP address from main server IP or the one defined in SECOND_IP variable, then right now you would need to manually edit your Nginx vhost config file's listen directive yourself defining the additional IP you added earlier and restart Nginx server afterwards

Code (Text):

service nginx restart

or centmin mod command shortcut

Code (Text):

ngxrestart

 

yup you can do that add SECOND_IP once for new vhost and then remove it from /etc/centminmod/custom_config.inc

 

yes commented out in vhost so just uncomment it

as to running csfcf.sh you can do it before or after as 123.09beta01 initial install already runs it once these days to populate the include file
