Docker MariaDB + MySQL + PHP FPM + Nginx Reverse Proxy + Nginx WordPress + PhpMyAdmin Setup

Ok, im migrating this website to another server using docker. This is how i setup my multi site with Docker Nginx and MariaDB or MySQL if you wonder. Here is what i did,

Install MariaDB / MySQL

Look for MariaDB on the offical Docker hub, we are going to install the one below,

docker run --restart=always --name mariadb -v /root/mysql:/var/lib/mysql -v /root/mysql/conf.d:/etc/mysql/conf.d -e MYSQL_ROOT_PASSWORD=PassWord10 -d mariadb:latest

So all our data record are located at /root/mysql with the root password as shown above using the 'latest' tag for the latest mariadb.

Install PhpMyAdmin

Now i need to manage my MySQL externally so im going to install PhpMyAdmin using the official Docker hub image i create an image with the name phpmyadmin.

docker run --restart=always --name phpmyadmin -d --link mariadb:db -p 8080:8080 phpmyadmin/phpmyadmin

The creates a phpmyadmin that links to my mariadb container using port 8080. Hence, if you are going to visit phpmyadmin, just head over to localhost:8080

Install Nginx Reverse Proxy

As for reverse proxy im using one of the open image

docker run -d -p 80:80 -p 443:443 --restart=always --name proxy -v /root/nginx/htpasswd:/etc/nginx/htpasswd -v /root/nginx/ssl:/etc/nginx/certs  -v /var/run/docker.sock:/tmp/docker.sock:ro  jwilder/nginx-proxy

This creates a few folder on my host machine so i could manage my virtual host and open up both port 80 and 443 for SSL enabled website.

Now to generate SSL into /root/nginx/ssl i use the following

openssl req -x509 -newkey rsa:2048 -keyout default.key -out default.crt-days 9999

and our virtual host should be able to support SSL on port 443

Install PHP+FPM

So i need PHP+FPM, hence, i added the container below using the image from the offical php but with my own DockerFile but you can use mine as shown below,

docker run -it --restart=always --name phpfpm --link mariadb:mysqlip -v /root/www:/home claylua/phpfpm

well, i keep the default name of phpfpm and i keep the dockerfile in my github.

Install Nginx

Now i need to install WordPress but before that i will need a web server and im using Nginx in this case, using the official nginx image, i run a subdomain of

docker run 
--link mariadb:mysqlip 
--link phpfpm:phpfpm 
-v /root/nginx/conf.d/ 
-v /root/nginx/ssl/
-v /root/nginx/conf/ 
-v /root/www/ 
-d -p 10295:80 nginx

Take note that the port should be different and can be anything with the path to the host at your own discrete. For each path, i am trying to create a custom installation for the web server folder and nginx configuration. Hence, for each nginx configuration on your host, do add the following nginx.conf into the path you have specific above.

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/;

events {
    worker_connections  1024;

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;

After this we will need to do a proxy for all php files to the phpfpm container we just created previously. head over to /root/nginx/sites-available/ and create a new file call default and paste the following code

server {
    listen       80;
    listen 443 ssl;

    root   /home/;

    location / {
        index  index.html index.htm index.php;
        try_files $uri /index.php$is_args$args;

    location ~ \.php$ {
            include fastcgi_params;
            fastcgi_pass  phpfpm:9000;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name;

And since our php files is located at /var/www/ we will just place everything there for all our php request.

Test it!

Now once you are done with the above, start all your container, restart your server, and whatever you do, make sure that everything still works perfectly for you!

*** UPDATE ***

In case you are wondering where i host my website, i am currently hosting with Digital Ocean, using their 512MB node, highly recommended and very stable so far as compare to other provider i have been with. You can choose Vulr as well, which provides you higher memory and disk space with many other options to help yous ave cost.

  1. Great post. Thanks. However, I do not get the point why to use phpmyadmin/phpmyadmin image and install php there, since we have the separate container of php?

  2. Oh! i didn't really spotted that part! But yeah, there's no point in using a phpmyadmin with php image though! i have execuses! just lazy i guess! 😡
