inanzzz | Serving multiple sites on multiple Nginx ports and different roots

This example shows us how to set multiple websites on different ports. We also changed default web root from /var/www/html to /srv/www.

Structure

srv
.
└── www
    ├── index.php    # Default site root
    ├── phpinfo.php  # Default site root
    └── symfony
            └── public
                ├── index.php    # Symfony site root
                └── phpinfo.php  # Symfony site root

Default

This is the "default" website configuration which uses port 80.

$ cat /etc/nginx/sites-available/default
server {
    listen 80 default_server;

    root /srv/www;

    server_name default.dev;

    # Return 404 for all other files not matching the .php files
    location / {
        index index.php index.html index.htm;
        try_files $uri $uri/ =404;
    }

    # Pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/run/php/php7.2-fpm.sock;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }

    error_log /var/log/nginx/default_error.log;
    access_log /var/log/nginx/default_access.log;
}

Symfony

This is the "symfony" website configuration which uses port 81.

$ cat /etc/nginx/sites-available/symfony
server {
    listen 80; # Enables internal access without passing :81
    listen 81; # Enables external access with passing :81

    server_name symfony.dev;

    root /srv/www/symfony/public;

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

    location ~ ^/index\.php(/|$) {
        fastcgi_pass unix:/run/php/php7.2-fpm.sock;
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
        fastcgi_param DOCUMENT_ROOT $realpath_root;
        internal;
    }

    location ~ \.php$ {
        return 404;
    }

    error_log /var/log/nginx/symfony_error.log;
    access_log /var/log/nginx/symfony_access.log;
}

Hosts

$ cat /etc/hosts
127.0.0.1	default.dev
127.0.0.1	symfony.dev

Tests

The actual address of the server is 192.168.99.30.

Default

You can use localhost, 127.0.0.1 or default.dev if you want to. Port 80 is optional for all hosts because this is the default site.

# Internal tests
$ curl 127.0.0.1                  # serves index.php
$ curl 127.0.0.1/index.php
$ curl 127.0.0.1/phpinfo.php
$ curl 127.0.0.1:80               # serves index.php
$ curl 127.0.0.1:80/index.php
$ curl 127.0.0.1:80/phpinfo.php

# External tests from browsers
http://192.168.99.30/             # serves index.php
http://192.168.99.30/index.php
http://192.168.99.30/phpinfo.php

Symfony

You can use localhost, 127.0.0.1 or symfony.dev if you want to. Port 81 is optional only for symfony.dev but not others.

# Internal tests
$ curl 127.0.0.1:81                # serves index.php
$ curl 127.0.0.1:81/index.php
$ curl 127.0.0.1:81/phpinfo.php
$ curl symfony.dev                 # serves index.php
$ curl symfony.dev/index.php
$ curl symfony.dev/phpinfo.php
$ curl symfony.dev:81
$ curl symfony.dev:81/index.php
$ curl symfony.dev:81/phpinfo.php

# External tests from browsers (port is compulsory)
http://192.168.99.30:81/           # serves index.php
http://192.168.99.30:81/index.php
http://192.168.99.30:81/phpinfo.php
