Nginx: proxy_pass path of domain to different web server

Question

We plan to upgrade our web application from php native based application to PHP Framework based (Laravel) to enhance application security and performance. My task is to split traffic where every request pointed to domain app.localhost without postfix /v3 still forwarded to old application on php-native web server node, and proxy all request with /v3 path to laravel web server node. Below is my configuration that resulting all asset (css and js) and URL generated by Laravel pointed to root path.

Laravel generated URL pointed to old application

Front Proxy (Public Network)

server { listen 80; listen [::]:80; server_name app.localhost; # PHP Native APP location / { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_pass http://php-native/; } # Laravel (APP v3) location /v3/ { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_pass http://laravel/; } } 

Web Servers (Private Network)

php-native Web Server

server { listen 80; listen [::]:80; server_name app.localhost; root /usr/share/nginx/html/webapp/app; location / { index index.php index.html index.htm; try_files $uri $uri/ /index.php?$query_string; } location ~ \.php$ { fastcgi_pass php56-fpm:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /var/www/html/webapp/app/$fastcgi_script_name; include fastcgi_params; } } 

laravel Web Server

server { listen 80; server_name app.localhost; root /usr/share/nginx/html/webapp/app-v3/public; index index.php index.html index.htm; location / { index index.php index.html index.htm; try_files $uri $uri/ /index.php?$query_string; } location ~ \.php$ { fastcgi_pass php74-fpm:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /var/www/html/webapp/app-v3/public/$fastcgi_script_name; include fastcgi_params; } } 

Thanks

Update

My question is: how to split the traffic, so any request pointed to app.localhost still forwarded to php-native web server and all request pointed to app.localhost/v3 pointed to laravel web server ?

Answer 1

i'm already found my solution.

Step 1: Add X-Frowarded-Prefix to Front Proxy

server { listen 80; listen [::]:80; server_name app.localhost; # PHP Native APP location / { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_pass http://php-native/; } # Laravel (APP v3) location /v3/ { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-Prefix "/v3"; proxy_pass http://laravel/; } } 

Step2: Overide getTrustedHeaderNames function

protected function getTrustedHeaderNames() { switch ($this->headers) { case 'HEADER_X_FORWARDED_AWS_ELB': case Request::HEADER_X_FORWARDED_AWS_ELB: return Request::HEADER_X_FORWARDED_AWS_ELB; case 'HEADER_FORWARDED': case Request::HEADER_FORWARDED: return Request::HEADER_FORWARDED; case 'HEADER_X_FORWARDED_FOR': case Request::HEADER_X_FORWARDED_FOR: return Request::HEADER_X_FORWARDED_FOR; case 'HEADER_X_FORWARDED_HOST': case Request::HEADER_X_FORWARDED_HOST: return Request::HEADER_X_FORWARDED_HOST; case 'HEADER_X_FORWARDED_PORT': case Request::HEADER_X_FORWARDED_PORT: return Request::HEADER_X_FORWARDED_PORT; case 'HEADER_X_FORWARDED_PROTO': case Request::HEADER_X_FORWARDED_PROTO: return Request::HEADER_X_FORWARDED_PROTO; // add this to support x-forwarded-prefix case 'HEADER_X_FORWARDED_PREFIX': case Request::HEADER_X_FORWARDED_PREFIX: return Request::HEADER_X_FORWARDED_PREFIX; // add | Request::HEADER_X_FORWARDED_PREFIX default: return Request::HEADER_X_FORWARDED_FOR | Request::HEADER_X_FORWARDED_HOST | Request::HEADER_X_FORWARDED_PORT | Request::HEADER_X_FORWARDED_PROTO | Request::HEADER_X_FORWARDED_AWS_ELB; } return $this->headers; }
