Docker Nginx + Multiple domains + multiple wordpress on their own directories in 1 vps

Question

Currently, I want to run multiple wordpress sites with multiple domains in 1 vps. I hope I can separate each wordpress in separated sub folders.

I tried with many different ways but I always got 404 error at the first time I visit to setup wordpress.

Here is my error log in nginx error.log

*6 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 192.168.63.1, server: site1.com, request: "GET / HTTP/1.0", upstream: "fastcgi://172.21.0.4:9000", host: "192.168.63.130"

Could anyone explain to me what I'm doing wrong? Thank you!

Maybe it will help someone. I successfully deployed multiple (domains) WordPress docker containers with single Nginx docker.

docker-compose.yml:

version: '3'

services:
  db:
    image: mysql:8.0
    container_name: db
    restart: unless-stopped
    env_file: .env
    environment:

nginx-conf/domain1.com.conf (wordpress2 site nginx config is pretty much the same - just replace domain1 with domain2)

server {

    listen [::]:80;

    ssl_certificate /etc/letsencrypt/live/domain1.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/domain1.com/privkey.pem;

    location / {

    }

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass wordpress:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME /var/www/html$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
    }

    location ~ /\.ht {
        deny all;
    }

    location = /favicon.ico {
        log_not_found off; access_log off;
    }
    location = /robots.txt {
        log_not_found off; access_log off; allow all;
    }
    location ~* \.(css|gif|ico|jpeg|jpg|js|png)$ {
        expires max;
        log_not_found off;
    }
}

I spent hours if not days to figure out I need to change:

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

to

fastcgi_param SCRIPT_FILENAME /var/www/html$fastcgi_script_name;

Hope I will spare some extra hours to anyone.

won't the wordpress service in the nginx config will be of the wordpress service of the respective site?

I add a Dockerfile site1_build/Dockerfile:

FROM  wordpress:php7.2-fpm
WORKDIR /var/www/html/site1

In the docker-compose.yml file:

 site1:
    build: ./site1_build
    container_name: site1
    volumes:
      - ./wordpress/site1:/var/www/html/site1

Am I correct in assuming that you would of course have built two Dockerfiles? Site1 and Site2.

AmaChefe Over a year ago

You need different container per site. You can create many containers using the same Dockerfile but change the name of the container during the build

Uros Majeric's answer helped me (not enough reputation to comment)

However, I had to change each of the Docker volume in the Wordpress container to exactly match the nginx, ie.

  wordpress1:
  ###
    volumes:
      - wordpress1:/var/www/domain1.com

  wordpress2:
  ###
    volumes:
      - wordpress2:/var/www/domain2.com

The point is not to mount the volume to the same directory as wordpress Docker has its files in /var/www/html folder. I had the same config before as you wrote here, but because of this I had other issues. This is why SCRIPT_FILENAME in nginx config is pointing to the /var/www/html$fastcgi_script_name;!
