Nginx: How to use a different php-fpm pool depending on url

  • 772

I have a site using the standard nginx approach for directing traffic via /index.php regardless of url:

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

location ~ \.php$ {
    fastcgi_pass unix:/run/php/php7.0-fpm.sock;
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_index index.php;
    include fastcgi_params;
}

But I want to use a different php-fpm pool for a certain URL (but still going via /index.php). I could, I presume, use an "if" clause within the .php$ location block to use a different fastcgi_pass depending on the URL, but "if" is discouraged so is there another way?

  1. You can use the map feature for this. For example, define the map in http context as follows:

    map $request_uri $pool {
    "/path/to/special" unix:/run/php/special.sock;
    default unix:/run/php/php7.0-fpm.sock;
}

    And then at the location:

    location \.php$ {
    fastcgi_pass $pool;
}

    I haven't tested this approach myself, so you might need to tweak the $pool variable contents.
