Remove Exisiting Versions of Apache, PHP, MySQL and Cyrus
These compents can and will cause conflits with the Plesk install so your best of removing them run the following:
yum remove http*
yum remove php*
yum remove cyrus*
yum remove mysql*
You don’t need to run above Linux commands if you have fresh centos installed.
Disable SELinux status
SELinux or Security-Enhanced Linux will also cause conflits with the plesk install and when you are adding / creating websites, your best to disbale it.
On my VPS which installed centOS, it doesn’t have this file: cat /etc/sysconfig/selinux
Make a working directory
Make and navigate to your working directory where you will run the auto installer
Now we will wget the Plesk 11 installer for Centos 6 64 bit
this is 64bit CentOS version.
To give it execution permissions
chmod +x parallels_installer_v3.12.0_build120601.16_os_CentOS_6_x86_64
Run the auto installer
After installation, open Internet Browser and go to below URL:
https://your-server-ip-address:8447/ and start installation accordingly
