Install yum and php-pear on Centos 5

linux php centos 
Virtual server like Aruba virtual servers are configured with Centos without yum and without php-pear. Today I have done an assistance to a server of my customer that needed pear installation. It is quite simple to make all work but I don’t understand why Aruba’s staff have not decided to include yum in their own default configuration server…
Shall we start installing yum:
mkdir /root/matteo && cd /root/matteo

yum -y update
Now it’s time to install php-pear:
yum install php-pear*
Ok, in every virtual-host of Plesk (/var/www/vhosts/example.com/conf/httpd.include), there is the directive open_basedir that must be configured in the right way adding the pear path:
php_admin_value open_basedir "/var/www/vhosts/example.com/httpdocs:/tmp:/usr/share/pear:/local/PEAR"
We must also configure pear in /etc/php.ini
include_path=".:/usr/share/pear:/local/PEAR/"
At the end you shall restart Apache:
/etc/init.d/httpd restart
