How to: Upgrade PHP and MySQL

sshYour new Centox 6.x server running Plesk 12 will need to have PHP and MySQL upgraded before going in to production.

You can do this using the Atomicorp repositories.

Check the current PHP version

php -v

Download the Atomicorp repository and keys:

wget -q -O - http://www.atomicorp.com/installers/atomic.sh | sh

Use yum to upgrade PHP and MySQL

yum upgrade php mysql

Add the most commonly used PHP modules as required

yum install php-ioncube-loader php-mcrypt php-bcmath php-zend-guard-loader db4-utils

Restart the apache/httpd service gracefully…

service httpd graceful

…and test your PHP version.

php -v

Your PHP and MySQL upgrade is now complete.

How to: Set error_reporting in PHP.INI properly

sshYour new Centos 6.x server will quickly build up logs and the php.ini log is one that can get huge. If you only want to see real errors then you need no more than the following setting in your php.ini.

Edit your current PHP.INI

nano /etc/php.ini

Replace the error_reporting setting as follows

error_reporting = E_COMPILE_ERROR|E_ERROR|E_CORE_ERROR

In the even that you require a less strict log level, you can change the entry when required, debug your session then promptly change it back.
