LEMP stack built on Docker

Nginx + PHP-FPM 7 webserver through FastCGI with microcaching + MariaDB + included PhpMyAdmin, cAdvisor!

Work in progress! NOT FOR PRODUCTION!

Prerequisites

1. Linux
2. 1GB Ram
3. 20GB disk size (preferably fixed size in virtual machines)
4. Git
5. Docker Client
6. Systemd
7. Docker-compose

Installation

Basic install script provided. Run only ./install-lemp.sh and follow the instructions in the script! You doesn't even need to clone this repo (the script will do it anyway), just only download this file to your host and run it if you wish!

$ curl -L https://raw.github.com/DJviolin/LEMP/master/install-lemp.sh > $HOME/install-lemp.sh && chmod +x $HOME/install-lemp.sh && cd $HOME && ./install-lemp.sh && rm -rf $HOME/install-lemp.sh

The script will create the docker-compose.yml and lemp.service files inside the cloned repo, which are needed for docker-compose and systemd.

Usage

Run docker-compose with:

$ docker-compose --file $HOME/server-lemp/lemp/docker-compose.yml build

Start the Systemd service:

$ cd $HOME/server-lemp/lemp
$ ./service-start.sh

Stop the systemd service:

$ cd $HOME/server-lemp/lemp
$ ./service-stop.sh

PhpMyAdmin further setup

1. Create a new table called phpmyadmin
2. Into this new table, import sql/create_tables.sql from the original PhpMyAdmin archive which you can download from here: https://www.phpmyadmin.net/downloads/phpMyAdmin-latest-all-languages.tar.gz
3. At the Privileges tab, create a new user called pma with the password pmapass and grant all privileges!
4. Please not remove the $HOME/server/www/phpmyadmin folder on the host, although it's empty! This is the folder of the PhpMyAdmin installation.

Wordpress post install

1. You have to place this on the bottom of your wp-config.php:

   define('DISABLE_WP_CRON', true);
   

   This will turn off default cron jobs from WP. Then you have to create a file in $HOME/server-lemp/lemp/php/cron-jobs.sh directory and place this in there:

   #!/bin/bash
   
   while true; do
     date >> /var/log/cron-test.log 2>&1
     sleep 60
   done
   

   This hack will make cron jobs work again (like core, plugin, theme updates and scheduled tasks).

2. Install Nginx Helper plugin and turn on Enable Purge option.

3. You can verify that nginx Cache Purge option is installed. It should return nginx-cache-purge to the console:

   $ docker exec -it lemp_nginx bash
   $ nginx -V 2>&1 | grep ngx_cache_purge -o
   

   All of this achieved by following this tutorial.

Docker-compose installation on CoreOS

If you happens to be a CoreOS user and you want to install docker-compose, you can install it with superuser access:

$ sudo su
$ mkdir -p /opt/bin
$ curl -L https://github.com/docker/compose/releases/download/1.5.2/docker-compose-`uname -s`-`uname -m` > /opt/bin/docker-compose
$ chmod +x /opt/bin/docker-compose
$ exit

Or without any superuser access, from the nightly release channel:

# Removing symlink from /usr/share/skel/.bashrc in cave man style
$ cp $HOME/.bashrc $HOME/.bashrc.new
$ rm $HOME/.bashrc
$ mv $HOME/.bashrc.new $HOME/.bashrc
$ chmod a+x $HOME/.bashrc
# Echoing docker-compose PATH variable
$ echo -e 'export PATH="$PATH:$HOME/bin"' >> $HOME/.bashrc
$ curl -L https://dl.bintray.com/docker-compose/master/docker-compose-`uname -s`-`uname -m` > $HOME/bin/docker-compose
$ chmod +x $HOME/bin/docker-compose
# Reloading .bashrc without opening a new bash instance
$ source $HOME/.bashrc
