CakePHP 4 from a sub directory

by | Apr 25, 2022 | IT Tips | 0 comments

I have a default Nginx install on Ubuntu 22.04 LTS inside a Docker Container using

I want /var/www/html to remain as the root but a CakePHP 4 app to be served as follows

requests to hostname.example.com as served from /var/www/html
requests to hostname.example.com/subdir are served from /var/www/tgn/webroot

This link https://serversforhackers.com/c/nginx-php-in-subdirectory is for a laravel config. But doesn't seem to work properly with my CakePHP 4 install.

Note: See below for the problem I found using the above config

The ApacheConf default .htaccess located in webroot contains the following

?

5
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ index.php [L]
</IfModule>

So this is duplicated in Nginx as follows

Nginx Configuration to Serve CakePHP 4 from Sub Directory

This config is the working config!!!

The absolute_redirect value set to off stops nginx redirecting to an external URL. By default when a request is made for http://ipaddress:8080/wms it issues a redirect to http://ipaddress/wms/ which breaks my docker config. With absolue_redirect off it redirects from http://ipaddress:8080/wms => /wms/ and keeps the ipaddress:port combination correct and only issues a relative redirect

Partially working

This was an attempt but in this configuration it was issuing an external redirect and redirecting to port 80 instead of the original docker port due to a problem after login with it redirecting from http://10.19.23.87:6002/wms => http://10.19.23.87/wms/

NOT working Laravel for Hackers Config Follows

This was also causing the request to be appended. By that I mean a request to

http://10.19.23.87:6002/wms/pallets/onhand would return http://10.19.23.87:6002/wms/pallets/onhand?pallets/onhand

http://10.19.23.87:6002/wms/pallets/onhand?pallets/onhand?pallets/onhand

Until it reached the URL request length limit and NGinx returned an error
