nginx with multiple symfony2 apps - symfony

Question

I saw that many people had problem configuring one nginx server to have multiple symfony2 applications. However, none wanted the same things and had the same problem as me.
What I want to do is to have multiple applications on the same domain. One main application will answer directly to the domain, and the others will be on alias subdirectory.
With a schema :
http://mydomain/ -> main app
http://mydomain/subdir1 -> another app
http://mydomain/subdir2 -> yet another app
I tried by myself to do that and the main app works perfectly. But the subdirectories are most of the time intercepted by the main app, which throws 404. When I try to add app.php in the URL of a subdirectory (like http://mydomain/subdir1/app.php/my/route), the server return 404.
This is what I did until now :
server {
listen 80;
server_name mydomain;
root /server/www/main-app/web;
location / {
# try to serve file directly, fallback to app.php
try_files $uri /app.php$is_args$args;
# PROD
location ~ ^/app\.php(/|$) {
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param HTTPS off;
}
}
location /subdir1/ {
alias /server/www/other-app1/web;
# try to serve file directly, fallback to app.php
try_files $uri /server/www/other-app1/web/app.php$is_args$args;
# PROD
location ~ ^/other-app1/app\.php(/|$) {
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param HTTPS off;
}
}
}
Thanks you for your help !
EDIT 26/12/2014 :
For those who did not understand exactly what I want : I want to host multiple symfony2 apps on the same domain name without subdomain. Without subdomain, I must use subdirectory. Before that I tried nginx, I used Apache2 and it was easy to do the trick with Alias.
I did more search and found out that "alias" and "try_files" aren't good friends (see this bug report : http://trac.nginx.org/nginx/ticket/97). So I activated debug mode and did many tests.
Now I almost did it. The main apps no longer intercepts subdirectories and the others apps answer.
But those others apps answer by 404 so I looked in their logs. And I found out that they looked for URL pattern with the subdirectory in it. For instance they searched /subdir1/login instead of /login.
So this is my new configuration :
server {
listen 80;
server_name mydomain;
root /server/www/main-app/web;
location #rewriteapp {
rewrite ^(.*)$ /app.php/$1 last;
}
location /subdir1/ {
set $root "/server/www/other-app1/web";
# try to serve file directly, fallback to app.php
try_files $uri #rewriteapp;
}
location / {
index app.php;
set $root "/server/www/main-app/web";
# try to serve file directly, fallback to app.php
try_files $uri #rewriteapp;
}
# PROD
location ~ ^/app\.php(/|$) {
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $root$fastcgi_script_name;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
}
}
As you can see, the trick was to not use $document_root for the SCRIPT_FILENAME and I created my own instead. I don't know how the symfony2 router search the pattern in the URL, but with my previous configuration (Apache2) I never had this problem. So maybe their is another trick to send the correct path to script app.php.
Thanks you again for your help !

Answer 1

This solved it finally for me (thanks to Claros answer), after million things i tried. Like this, urls like the following work:
/abc/path/to/endpoint
but not /abc/app.php/path/to/endpoint. Config.php and App_dev.php, if in web folder are given back as plain text.
I still try to figure out to get /abc to work (/abc/ works but /abc not). There i get a Symfony exception that route /abc can not be found.
Also some font urls (for bootstrap) are still incorrect but styles, routing etc works.
location /abc {
set $subpath /abc;
set $sfPath /var/www/abc/current/web;
alias $sfPath;
try_files $uri #rewrite;
}
location / {
set $subpath "";
set $sfPath /var/www/def/current/web;
alias $sfPath;
try_files $uri #rewrite;
}
location #rewrite {
rewrite ^(.*)$ $subpath/app.php$1 last;
}
location ~ /app\.php(/|$) {
internal;
include /etc/nginx/fastcgi_params;
fastcgi_index app.php;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_param DOCUMENT_ROOT $sfPath;
fastcgi_param SCRIPT_FILENAME $sfPath/app.php;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
}
If you want also the app_dev.php to work in demo environment the best way i found is the following (to have the php block everytime inside the location block):
location /xyz {
set $subpath /xyz;
set $sfPath /var/www/xyz/current/web;
alias $sfPath;
try_files $uri #rewrite;
#Change the match for app_dev.php to work
location ~ /(app|app_dev|config)\.php(/|$) {
#Drop the internal for App_dev.php to work
#internal;
include /etc/nginx/fastcgi_params;
fastcgi_index app.php;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_param DOCUMENT_ROOT $sfPath;
fastcgi_param SCRIPT_FILENAME $sfPath/app.php;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
}
}

Answer 2

After many hours of debugging, I finally solved the problem. This is my final configuration :
server {
listen 80;
server_name mydomain;
root /server/www;
location #rewriteMainApp {
rewrite ^(.*)$ /app.php/$1 last;
}
location #rewriteOtherApp1 {
rewrite ^(.*)$ /subdir1/app.php/$1 last;
}
location /subdir1 {
alias /server/www/other-app1/web;
index app.php;
set $subfolder "other-app1/web";
try_files $uri #rewriteOtherApp1;
}
location / {
root /server/www/main-app/web;
index app.php;
set $subfolder "main-app/web";
try_files $uri #rewriteMainApp;
}
# PROD
location ~ /app\.php(/|$) {
fastcgi_pass unix:/var/run/php5-fpm.sock;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root/$subfolder/app.php;
}
}
Thanks you all for your help !

Seperate your applications with-in another server tag in your sites-enabled file.
For example:
#Site 1
server {
#Configuration
}
server {
#Configuration 2
}
server {
#Configuration 3
}
Sample configuration:
server {
listen 80;
root /var/www/yourdomain.com/web;
server_name yourdomain.com www.yourdomain.com;
add_header X-UA-Compatible "IE=Edge,chrome=1";
location ~* \.(css|js|gif|jpe?g|png)$ {
expires 1y;
add_header Pragma public;
add_header Cache-Control "public, must-revalidate, proxy-revalidate";
}
location / {
try_files $uri #rewriteapp;
}
location #rewriteapp {
rewrite ^(.*)$ /app_dev.php/$1 last;
}
location ~ ^/(app|app_dev|config)\.php(/|$) {
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param HTTPS off;
}
error_log /var/log/nginx/yourdomain.com.error.log;
access_log /var/log/nginx/yourdomain.com.access.log;
}
server {
listen 80;
root /var/www/yourdomain.com/anotherproject/web;
server_name sub1.yourdomain.com www.sub1.yourdomain.com;
add_header X-UA-Compatible "IE=Edge,chrome=1";
location ~* \.(css|js|gif|jpe?g|png)$ {
expires 1y;
add_header Pragma public;
add_header Cache-Control "public, must-revalidate, proxy-revalidate";
}
location / {
try_files $uri #rewriteapp;
}
location #rewriteapp {
rewrite ^(.*)$ /app_dev.php/$1 last;
}
location ~ ^/(app|app_dev|config)\.php(/|$) {
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param HTTPS off;
}
error_log /var/log/nginx/sub1.yourdomain.com.error.log;
access_log /var/log/nginx/sub1.yourdomain.com.access.log;
}
