Apache 2  

The configuration file of the Apache service is in the file /etc/httpd/conf/httpd.conf.  

The Apache documentation is available under http://httpd.apache.org/docs/.

MySQL  

You must create a root password before you can use the MySQL server in a production environment. The following code shows an example of how to do it:

# mysql
mysql> USE mysql;
mysql> UPDATE user SET Password=PASSWORD('newpassword') WHERE user='root';
mysql> FLUSH PRIVILEGES;

The configuration file for the MySQL service is available in /etc/my.cnf.
The documentation is available at http://dev.mysql.com/doc/. 
 

PHP  

You can find the configuration file for PHP in /etc/php.ini.
