nginx sites in subfolders - php

Question

I have some trouble getting my nginx setup work the way I want. I have a site example.localhost that is located at /vagrant/frontend/www. My configuration for this, which is working, looks like this:
server {
listen 80;
server_name example.localhost;
root /vagrant/frontend/www;
index index.php;
location / {
try_files $uri $uri/ /index.php$is_args$args;
}
location ~ .*\.php$ {
include /etc/nginx/fastcgi.conf;
try_files $uri = 404;
fastcgi_pass 127.0.0.1:9000;
}
}
But then I want to add an admin site, located at /vagrant/backend/www, to the address example.localhost/admin. This is when things go wrong, and I get a 404 not found with the setup below, based on this post:
location /admin {
root /vagrant/backend/www;
}
location ~ /admin/.+\.php$ {
include /etc/nginx/fastcgi.conf;
try_files $uri = 404;
fastcgi_pass 127.0.0.1:9000;
}
The error log looks like this:
2014/04/23 12:30:10 [error] 15459#0: *1 "/vagrant/backend/www/admin/index.php" is not found (2: No such file or directory), client: 192.168.56.1, server: example.localhost, request: "GET /admin/ HTTP/1.1", host: "example.localhost"
I see why I get a 404, but how do I get this right? Any help is much appreciated!
UPDATE
I have changed my admin location to this:
location /admin {
alias /vagrant/backend/www/;
try_files $uri $uri/ /index.php?$args;
location ~ \.php$ {
include /etc/nginx/fastcgi.conf;
fastcgi_pass 127.0.0.1:9000;
}
}
I have also removed this block:
location ~ /admin/.+\.php$ {...}
Now a call to example.localhost/admin gets processed correct, but if I change it to eg example.localhost/admin/site/index, the request is processed by the frontend. It looks like the /admin location doesn't match... Any thoughts?

Answer 1

location blocks are completely independent. Your request ends up in last location block and never see root directive from first one. Put root directive to second block.
location ~ /admin/.+\.php$ {
root /vagrant/backend/www;
include /etc/nginx/fastcgi.conf;
try_files $uri = 404;
fastcgi_pass 127.0.0.1:9000;
}

Answer 2

server {
listen 80;
server_name example.localhost;
root /vagrant/frontend/www;
index index.php;
location / {
try_files $uri $uri/ /index.php?$args;
location ~ \.php$ {
include fastcgi.conf;
}
}
location /admin {
return 301 /admin/;
}
location /admin/ {
alias /vagrant/backend/www/;
try_files $uri $uri/ #handler;
location ~ \.php$ {
include fastcgi.conf;
}
}
location #handler {
rewrite / /admin/index.php?$args;
}
}
