NGINX server block configuration for hosting multiple websites on Ubuntu 16.04

Question

I want to host multiple wordpress websites on a Ubuntu 16.04 (Ubuntu-NGINX-MariaDB-PHP). I don't want to use wordpress multisite.

I followed this guide . Everything is fine but I can host only one site. Whenever I created multiple server block configuration, it starts to show error and NGINX fail to start. I am not getting my config file correct. Here is the config file :

server {
     listen [::]:80 ipv6only=off;
     server_name abcde.org www.abcde.org;

     root /var/www/abcde;

    # Add index.php to the list if you are using PHP
    index index.php     index.html index.htm index.nginx-debian.html;

    location / {
        # First attempt to serve request as file, then
        # as directory, then fall back to displaying a 404.
        # try_files $uri $uri/ =404;
        try_files $uri $uri/ /index.php?q=$uri&$args;
    }

            error_page 404 /404.html;
            error_page 500 502 503 504 /50x.html;
            location = /50x.html {
                root /usr/share/nginx/html;
        }

     location ~ \.php$ {
        include snippets/fastcgi-php.conf;
    #
    #   # With php7.0-cgi alone:
        fastcgi_pass 127.0.0.1:9000;
    #   # With php7.0-fpm:
    #   fastcgi_pass unix:/run/php/php7.0-fpm.sock;
     }


     location ~ /\.ht {
        deny all;
     }
}

If I host only one website, it works fine. But as soon as I host the other website, NGINX fail to start. I use same config for both sites, after changing the server name and root directory.

Kindly guide me for the right configuration for NGINX server blocks.

Solution

Your nginx.config needs something like this line. This is what I do on my server

include /etc/nginx/enabled-sites/*;

In that directory you can have one file with many servers, or you can do what I do and have servers grouped by domain.

File abcde.conf

server {
  listen 80;
  server_name www.abcde.org;

  root /var/www/home;

  # Any locations you want. PHP example that I use below.
  location ~ \.php$ {
    fastcgi_keep_conn on;
    fastcgi_intercept_errors on;
    fastcgi_pass   php;
    include        fastcgi_params;
    fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
  }
} # ends www.abcde.org server

# This server forwards to the www domain
server {
  listen 80;
  server_name abcde.org;
  return 301 https://www.abcde.org$request_uri;
} # ends abcde.org server

File example.conf

# server for a completely separate domain
server {
  listen 80;
  server_name www.example.com;

  root /var/www/example;

  # Any locations you want
} # ends www.example.com server

File default_server.conf

# This just prevents Nginx picking a random default server if it doesn't
# know which server block to send a request to
server {
  listen      80 default_server;
  server_name _;
  # This means "go away", effectively. You can also forward somewhere
  # or put default_server onto any of your server blocks.
  return      444; 
}
