How to use nginx point to different applications while using the same domain

  • 772

I have 2 cakephp applications: one is using cake 2 and the other is using cake 3.

This is my nginx config

server {
        listen 80;
        client_max_body_size 2M;
        server_name cake.dev;
        root /var/virtual/cake2app/webroot;
        location /cake3-app/ {
                alias /var/virtual/cake3app/webroot;
        }

        access_log /var/log/nginx/cakephpsite.com-access.log;
        include common.conf;
        include cakephp.conf;
}

This is common.conf

index index.html;

location ~ /\.ht {
        deny all;
}
sendfile off;

This is cakephp.conf

include php.conf;

location / {
        try_files $uri $uri/ /index.php?$uri&$args;
        expires max;
        access_log off;
}

This is php.conf

location ~ \.php$ {
        fastcgi_pass 127.0.0.1:9000;
        include fastcgi_params;
}

index index.php;

the cake.dev is correctly pointing to my cake 2 app.

I cannot get cake.dev/cake3-app to point to the cake 3 app.

Inside my cake 3 app, I have a users/login action which works perfectly if I access the cake 3 from a separate domain.

But that is not what I want.

What have I done wrong in terms of the nginx config?

My error is consistently a 403 if I access cake.dev/cake3-app/ and I get a cake error message telling me there is no such controller when I access cake.dev/cake3-app.

Please advise.

EDIT:

I manage to use this trick. Inside my cakedev.conf

I wrote

server {
        listen 80;
        client_max_body_size 2M;
        server_name cake.dev;
        root /var/virtual/cake2/webroot;
        access_log /var/log/nginx/cakephpsite.com-access.log;
        include common.conf;
        include cakephp.conf;
        location /cake3-app/ {
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header HOST $http_host;
                proxy_set_header X-NginX-Proxy true;

                proxy_pass http://127.0.0.1:83;
                proxy_redirect off;
                rewrite ^/cake3-app/(.*)$ /$1 break;
        }
}

Then I have a cake3.conf 

server {
        listen 83;
        client_max_body_size 2M;
        server_name 127.0.0.1;
        root /var/virtual/cake3/webroot;
        include common.conf;
        include cakephp.conf;
}

The url redirect works for the web pages but NOT the various assets of the cake3 app.

Cake3App auto points to http://cake.dev/css/base.css when it should be pointing to http://cake.dev/cake3/css/base.css

Perhaps I need to write something different for the common.conf and the cakephp.conf for the cake3.conf?

nginx

    There are 3 steps. First 2 are nginx-related. Last one is cakephp-related.

    Step 1: Need to inform the config responsible for server_name http://cake.dev to redirect http://cake.dev/cake3 urls to the right config

    Assuming cakedev.conf is the config responsible for http://cake.dev

    server {
        listen 80;
        client_max_body_size 2M;
        server_name cake.dev;
        root /var/virtual/cake2/webroot;
        access_log /var/log/nginx/cakephpsite.com-access.log;
        include common.conf;
        include cakephp.conf;
        location /cake3-app/ {
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header HOST $http_host;
                proxy_set_header X-NginX-Proxy true;

                proxy_pass http://127.0.0.1:83;
                proxy_redirect off;
                rewrite ^/cake3-app/(.*)$ /$1 break;
        }
}

    Notice how I write the proxy_pass? It goes to 127.0.0.1:83. This is crucial though I suspect you can change the port number.

    Step 2: Write up the config responsible for cake3

    Assuming the file is cake3.conf

    server {
        listen 83;
        client_max_body_size 2M;
        server_name 127.0.0.1;
        root /var/virtual/cake3/webroot;
        include common.conf;
        include cakephp.conf;
}

    Notice how the server_name and the listen matches with the proxy_pass from the earlier config? This is crucial.

    Step 3: Change the App.base inside cake3

    Go inside your cake 3 app and look for config/app.php

    Change this value

    'App' => [
    'namespace' => 'App',
    'encoding' => 'UTF-8',
    'base' => false,

    to

    'App' => [
    'namespace' => 'App',
    'encoding' => 'UTF-8',
    'base' => '/cake3-app', // please make sure you start with a / and NEVER end with a /
