How to merge two nginx configurations - drupal

Question

I have 2 nginx configurations. Both of them work well alone. One of them is for drupal (frontend) and one of them is the backend. At the end I would like to have mydomain.com/ = frontend & mydomain.com/backend = backend.
Unfortunately I don't know what I have to do to make this work.
Here both configs:
//Drupal
upstream fcp {
server unix:/var/run/php-fpm.sock;
}
server {
listen 80;
server_name www.example.com;
root /usr;
location / {
index index.php;
}
location ~ \.php$ {
fastcgi_pass fcp;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /usr$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_script_name;
include /usr/local/nginx/conf/fastcgi_params;
}
}
// ====== //
// Backend-Software
upstream backend{
server unix:/var/run/php-fpm.sock;
}
server {
[...]
server_name www.example.com;
root /usr/backend/wwwroot;
#Generic definition
location / {
index index.php;
try_files $uri $uri/ /index.php?route=$uri&$args;
}
#backend.net frontend controller (redirect these calls to PHP-FPM)
location ~ ^/index.php {
fastcgi_pass backend;
fastcgi_param SCRIPT_FILENAME /usr/backend/wwwroot$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_script_name;
include /etc/nginx/fastcgi_params;
}
# Internal link to the files for X-Accel support
location /_files {
internal;
alias /usr/backend/_files/filesource/;
}
#Static Resources
location /wwwres/ {
expires 365d;
alias /usr/backend/wwwres/;
}
location ~ ^/wwwres/mod/([^/\.]*)/(.*)$ {
expires 365d;
alias /usr/backend/modules/$1/wwwres/$2;
}
location ~ ^/wwwres/vendor/([^/\.]*)/([^/\.]*)/(.*)$ {
expires 365d;
alias /usr/backend/vendor/$1/modules/$2/wwwres/$3;
}
location ~ ^/wwwres/theme/set_([^/\.]*)/(.*)$ {
expires 365d;
alias /usr/backend/_files/theme_set/$1/$2;
}
location ~ ^/wwwres/theme/([^/\.]*)/(.*)$ {
expires 365d;
alias /usr/backend/themes/$1/wwwres/$2;
}
location ~ ^/wwwres/vendor_theme/([^/\.]*)/([^/\.]*)/(.*)$ {
expires 365d;
alias /usr/backend/vendor/$1/themes/$2/wwwres/$3;
}
location ~ ^/_cache/(.*)$ {
expires 365d;
alias /usr/backend/_cache/$1;
}

}
}

I think you can merge these configurations into one server section. The root in this section can be /usr (from first section - is this correct?) or /usr/backend/wwwroot. You should decide which will be the default (www.example.com): the /usr/index.php or the /usr/backend/wwwroot/index.php. As I see you want /usr/index.php so your root should be /usr. And should add
location /backend {
root /usr/backend;
...
}
The location /_files and "Static Resources" will right because you use alias in every section.
Summary:
http {
server_name example.com;
root /usr;
index index.php;
location /backend_uri {
alias /usr/backend; # if "backend_uri"=="backend" (and root is /usr) this section is unnecessary
}
location /_files {
# same as your post
}
# Static resources
# same as your post
}
