    I finally got LetsEncrypt setup on my domain by way of this tool (manual, vhost was already setup):
    Generate Centmin Mod Nginx Vhost - CentminMod.com LEMP Nginx web stack for CentOS

    Everything is setup properly and I'm not receiving any SSL warnings.

    There is no cron file located in /usr/local/nginx/conf/ssl/example.com/example.com-cron

    What option do I have to auto-renew?
    Currently running Centminmod 123.09beta01 on CentOS 7.

    Thanks!

    Letsencrypt integration was rewritten from ground up as addons/acmetool.sh so there is no example.com-cron file anymore, just a simple cronjob for acme.sh
    Code (Text):
    0 0 * * * "/root/.acme.sh"/acme.sh --cron --home "/root/.acme.sh" > /dev/null

    So when I went to addons/acmetool.sh acmeinstall I received:
    Code (Text):
    -----------------------------------------------------
check acme auto renew cronjob setup:
-----------------------------------------------------
0 0 * * * "/root/.acme.sh"/acme.sh --cron --home "/root/.acme.sh" > /dev/null
-----------------------------------------------------
acme.sh installed
-----------------------------------------------------

    Does this mean that the cron job is already setup and working correctly to auto-renew before expiration? Sorry I am really lost with LetsEncrypt :)

    Ahh cool, I have that cron job as well as some other Wordpress and Centmin jobs. Perhaps this is why my daily Yum updates aren't working...I don't see it on that list!

    Thanks again for the help. I wish I had LetsEncrypt somewhat figured out before I purchased a Comodo SSL Cert, although it was only $0.88 for Black Friday :) Good learning experience I guess

    Verifying yum-cron is working



    You can check your cron log at /var/log/cron to see if it ran
    Code (Text):
    grep yum.cron /var/log/cron | tail -10
Sep 29 03:24:01 vultr run-parts(/etc/cron.daily)[21165]: starting 0yum.cron
Sep 29 03:28:39 vultr run-parts(/etc/cron.daily)[21235]: finished 0yum.cron
Sep 30 04:45:01 vultr run-parts(/etc/cron.daily)[26324]: starting 0yum.cron
Sep 30 04:54:00 vultr run-parts(/etc/cron.daily)[26403]: finished 0yum.cron
Oct  1 03:39:01 vultr run-parts(/etc/cron.daily)[31068]: starting 0yum.cron
Oct  1 04:29:19 vultr run-parts(/etc/cron.daily)[31314]: finished 0yum.cron

    Looks like it's only running the 0yum-hourly.cron, and if it was working correctly I also would have received an email after the cron job.
    The yum-cron service is definitely running; I can't help but feel I left something important out.

    Well, it looks like my (relatively new) server isn't sending emails. I'll have to contact Linode about that.
    I believe that wouldn't be the problem since I'm still not seeing the daily cron logs.

    test email via SSH command with [email protected] being your email you want to test receipt for
    Code (Text):
    echo "test" | mail -s "test subject" [email protected]

    then check postfix logs
    Code (Text):
    tail -10 /var/log/maillog

    Not much to reply with, everything under
    Code (Text):
    received  delivered   deferred    bounced     rejected
    has a value of 0.

    I was under the assumption that you don't need the mail server fully setup to send mail (although it may be marked as spam).

    did you test email via SSH command with [email protected] being your email you want to test receipt for
    Code (Text):
    echo "test" | mail -s "test subject" [email protected]

    postfixlog command and /var/log/maillog should have entries after the test email

    DUH! It wasn't running...call me stupid. I thought it was enabled by default.
    I just started it and now I'm being spammed with a ton of queued messages.
    Still this Yum issue though :(

    it should be enabled by default !
    start and make sure reboot starts postfix with SSH commands
    Code (Text):
    service postfix start
chkconfig postfix on

    OK, looks like postfix is working correctly now!
    Now to wrap my head around Yum daily cron...
