There is some tweaking that we need to perform in order to make sure that Apache runs CakePHP applications smoothly. Many Apache installations may not require the following tweaking, as they might be set as default, but it is always a good idea to check if the following settings are present.

AllowOverwrite is Set to All

We need to make sure that the web root directory, or the directory in which we plan to keep CakePHP has AllowOverwrite set to all. We can do this by checking Apache’s main configuration file http.conf. This file should be located in the directory called conf, where we have installed Apache. In this file, there should be option for the web root directory. As the following configuration shows, the web root (which is L:/wamp/www for this particular installation) has a Directory entry in which the AllowOverwrite option is set to all. If the directory under web root, in which we plan to keep Cake, has a directory entry, we need to check that one too.

<Directory "L:/wamp/www"> 
     Options Indexes FollowSymLinks 
     AllowOverride all 
     Order Deny,Allow 
     Deny from all 
     Allow from 127.0.0.1
</Directory>

Mod_rewrite Module is Loaded

We also need to make sure that the Apache is loading the mod_rewrite module. To do this, we again have to check the http.conf file. There should be a section in the http.conf file named Dynamic Shared Object (DSO) Support, where all the different modules that are loaded by Apache are listed. The modules that are not being loaded are commented out with # in the beginning of the line. So, we need to make sure that the mod_rewrite module line is not commented out. If it is, we just need to remove the # from the beginning of the line:

     LoadModule rewrite_module modules/mod_rewrite.so

Make sure to restart Apache once you have made the above changes.
As long as the above configurations are set accordingly, Apache should be running CakePHP applications without any issues at all.
