    Centmin Mod has a lot of documentation on official site and forums which is highly suggested reading if you want to learn about and use Centmin Mod LEMP stacks. But here's a quick guide to installing Centmin Mod 123.09beta01 on recommended CentOS 7.x 64bit fresh virgin OS.

    Quick Links

    Quick Install & Setup

    Install Centmin Mod latest beta + set nginx vhost domain = with letsencrypt ssl certificate and http/2 https default (with http to https redirect can be done in a few SSH commands.

    Centmin Mod Install
    Code (Text):
    yum -y update; curl -O && chmod 0700 && bash

    Enable Letsencrypt integration by setting LETSENCRYPT_DETECT='y' variable in Centmin Mod persistent config file at /etc/centminmod/ The persistent config file allows you to customise and override Centmin Mod default settings/variables set it without actually modifying so your custom settings persist when Centmin Mod local code is updated at /usr/local/src/centminmod (from 123.09beta01 and higher that install directory is git backed as outlined here.)
    Code (Text):
    touch /etc/centminmod/
    echo "LETSENCRYPT_DETECT='y'" >> /etc/centminmod/

    Create a new Nginx vhost site with letsencrypt free ssl certificate where and DNS A record point to server IP using either addons/ outlined at

    Ensure intended vhost domain name's DNS is set and propagated to point A/AAAA DNS records to the server's IP address before running Centmin Mod Nginx vhost commands, otherwise Letsencrypt webroot authentication's domain validation will fail.

    Code (Text):
    cd /usr/local/src/centminmod/addons
    ./ issue lived

    or nv command line
    Code (Text):
    nv -d -s lelived -u ftpusername

    nv command help examples
    Code (Text):
    Usage: /usr/bin/nv [-d] [-s y|n|yd|le|led|lelive|lelived] [-u ftpusername]
      -d or
      -s  ssl self-signed create = y or n or https only vhost = yd
      -s  le - letsencrypt test cert or led test cert with https default
      -s  lelive - letsencrypt live cert or lelived live cert with https default
      -u  your FTP username
      /usr/bin/nv -d -s y -u ftpusername
      /usr/bin/nv -d -s n -u ftpusername
      /usr/bin/nv -d -s yd -u ftpusername
      /usr/bin/nv -d -s le -u ftpusername

    Important Information
    You are about to create an Nginx vhost site account with/without
    HTTPS/SSL support. Details of this process are outlined on site
    at Also read the
    continually updated Getting Started Guide for Centmin Mod usage
    at which covers the pure-ftpd
    ftp username that is auto generated with the Nginx vhost site.
    403 Permission denied message handling
    if after vhost site setup you encounter 403 permission denied errors,
    check to see if your
    site needs tools/ tweaking/whitelisting
    Do you want to continue with Nginx vhost site creation ? [y/n] y
    Enter vhost domain name to add (without www. prefix):
    Create a self-signed SSL certificate Nginx vhost? [y/n]: n
    Get Letsencrypt SSL certificate Nginx vhost? [y/n]: y

    Code (Text):
    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.
    continue [y/n] ? y
    You have 4 options:
    1. issue staging test cert with HTTP + HTTPS (untrusted)
    2. issue staging test cert with HTTPS default (untrusted)
    3. issue live cert with HTTP + HTTPS (trusted)
    4. issue live cert with HTTPS default (trusted)
    Enter option number 1-4:

    Create MySQL database named = mydb with username = myadmin and password = mypass using addons/ Shell based Addon

    Code (Text):
    /usr/local/src/centminmod/addons/ createuserdb mydb myadmin mypass
    Basic MySQL Admin - create mysql user & databases
    Grants for myadmin@localhost
    GRANT USAGE ON *.* TO 'myadmin'@'localhost' IDENTIFIED BY PASSWORD '*6C8989366EAF75BB670AD8EA7A7FC1176A95CEF4'
    Ok: MySQL user: myadmin MySQL database: mydb created successfully

    If that is too much for install, I also have official Linode stackscript for automated Centmin Mod installs at Linode - official centmin mod Linode stackscript

    So there's various ways to create domain nginx vhosts and mysql databases etc so you can script or automate your own setups. But yes, you're not going to know all this without reading and practicing :)
