When this problem occurs, check if you have installed two MySQL programs, one is the system comes with, and one is installed on its own.

Note: When starting the MySQL service, will search my.cnfin a certain order,first in the / etc directory to find, can not find the search "$basedir/my.cnf", in this case is /usr/local/mysql/my.cnf, which is the default location for the new MySQL configuration file! If you find/etc in the presence of my.cof files, directly deleted, so that when the start of MySQL will go /usr/local/mysql/my.cnfdirectory down to find your own installation of the article

Restart Apache directly under the path of the source installation by/usr/local/apache2/bin/apachectl this way, do not use/ETC/INIT.D/HTTPD to start, unless you say that the startup script is placed under/etc/init.d/, By default, yum installs the httpd startup script under/etc/init.d/

Here's how to fix it:

1. Check the Apache configuration file to see if the libphp5.so module is loaded, and if not, add

LoadModule Php5_module modules/libphp5.so

2. In the <ifmodule mime_module> module see if there is a PHP page added, if not

AddType application/x-httpd-php. php. php3. PhP4

3. Add index.php after the directoryindex of the <ifmodule dir_module> module
