Compiling custom php to the server and adding it to cpanel suphp

Compiling custom php to the server and adding it to cpanel suphp
To know the current settings in the server, use the following command:
===
/usr/local/cpanel/bin/rebuild_phpconf --current
====
Download the latest version of php. As of now the latest version of php is php-5.3.8.

====
cd /usr/src
wget http://us.php.net/get/php-5.3.8.tar.gz/from/this/mirror
tar -zvxf php-5.3.8.tar.gz
cd php-5.3.8
====

Collect the configuration options from the remote server and configure it using those options on the new server. Make sure the prefix is set as /usr/local/php-5.3.8 and the existing prefix option is removed from the compiling options. Also, make sure to check whether cgi is enabled in the configure options

./configure --prefix=/usr/local/php-5.3.8 --enable-cgi --other-options

make
make install
/usr/local/php-5.3.8/bin/php -v

The version will be shown by the php binary.

Adding new php binary to suphp: Add the line in the suphp.conf file to include the newly compiled php binary to suphp

vi /opt/suphp/etc/suphp.conf
[handlers]
application/x-httpd-php5.3="php:/usr/local/php-5.3.8/bin/php-cgi"

Add the following lines in the file /usr/local/apache/conf/includes/pre_main_2.conf if only the domain with the username "username" needs custom php.

<Directory "/usr/local/php-5.3.8/bin">
Allow from All
</Directory>
<Directory /home/username/public_html>
suPHP_AddHandler application/x-httpd-php5.3
AddType application/x-httpd-php5.3 .php
</Directory>

Restart apache if there is no error

/etc/rc.d/init.d/httpd configtest
/etc/rc.d/init.d/httpd restart

Note: confirm that the php.ini file is present in /usr/local/php-5.3.8/lib directory.Also check if the extension_dir in php.ini for 5.3 is the correct path. That is, /usr/local/php-5.3.8/lib/php/extensions/no-debug-non-zts-20090626.

If the new php should be set as global php, then edit the file /usr/local/apache/conf/php.conf as follows.

<Directory "/usr/local/php-5.3.8/bin">
Allow from All
</Directory>
<Directory />
suPHP_AddHandler application/x-httpd-php5.3
AddType application/x-httpd-php5.3 .php
</Directory>

Restart apache if there is no error

/etc/rc.d/init.d/httpd configtest
/etc/rc.d/init.d/httpd restart
