How to install symfony2 app in a subdirectory in nginx

Question

I need to install multiple symfony2 applications on the same host but on different subdirectories (or location blocks).

With this config nginx throws a "file not found" or redirect loop message when trying to access any url.

Example:

/login -> /base/login
/app1 -> /base/app1
/app2 -> /base/app2

Current Config:

root /base/default; #Points to an empty directory

# Login Application
location ^~ /login {
    alias /base/login/web;
    try_files $uri app_dev.php;
}

# Anything else
location ~ ^/([\w\-]+) {
    alias /base/$1/web;
    try_files $uri app_dev.php;
}

location / {
    # Redirect to the login
    rewrite ^ /login redirect;
}

# Handle PHP
location ~ \.php$ {
    include fastcgi_params;
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_param PATH_INFO $fastcgi_path_info;
    fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
    fastcgi_param HTTPS off;
    fastcgi_pass unix:/var/run/php5-fpm.sock;
}

After hours spended to find this (sf2 doc doesn't explain how cgi parameters are needed and interpreted, you need to go through Request.php to understand), so I share this.

This is a config which seems ok with sf2 in a directory {subdir} (and web access to others files than {subdir}/web/* prohibited).

It works for me with php-fpm (socket).

Of course, replace "{subdir}" by your /path/from/docroot/to/symfony_root/

dev environnement can be choosen by adding "dev" to "{subdir}" (since app_dev.php in the url no longer works with this conf)

server {

  # general directives

  location ~ ^/{subdir}(/.*)$ {   
    try_files /{subdir}/web$1 @sf2;
  }
  location ~ ^/{subdir}dev(/.*)$ {
    expires off;
    try_files /{subdir}/web$1 @sf2dev;
  }
  location @sf2 {
    expires off;
    fastcgi_pass   {your backend};
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $document_root/{subdir}/web/app.php;
    fastcgi_param SCRIPT_NAME       /{subdir}/app.php;
    fastcgi_param REQUEST_URI       /{subdir}$1;
  }
  location @sf2dev {
    expires off;
    fastcgi_pass   {your backend};
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $document_root/{subdir}/web/app_dev.php;   
    fastcgi_param SCRIPT_NAME       /{subdir}dev/app_dev.php;       
    fastcgi_param REQUEST_URI       /{subdir}dev$1;     
  }


  # other location directives

  # if some others apps needs php, put your usual location to cactch php here

}

I Hope it helps (and there isn't any misconfiguration), given without any guarantee...

Of course you can pick out prod/dev conf if you don't need. And you can use var and only one @sf2 location instead :

  set $sf2_root /{subdir};
  location ~ ^/{subdir}(/.*)$ {   
    set $sf2_prefix /{subdir};  
    set $sf2_ctrl app.php;
    try_files $sf2_root/web$1 @sf2;
  }
  location ~ ^/{subdir}dev(/.*)$ {
    set $sf2_prefix /{subdir}dev;
    set $sf2_ctrl app_dev.php;
    expires off;
    try_files $sf2_root/web$1 @sf2;
  }
  location @sf2 {
    expires off;
    fastcgi_pass   {your backend};
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $document_root$sf2_root/web/$sf2_ctrl;
    fastcgi_param SCRIPT_NAME       $sf2_prefix/$sf2_ctrl;
    fastcgi_param REQUEST_URI       $sf2_prefix$1;
  }
