Here are the complete steps on “How to install Plesk 8.x on a plain VPS Hosting / Dedicated server“..
Important Pre-Installation Tasks :
Login to the VPS Hosting/server & execute “uname -i” to get the OS bit version so that you can download the appropriate installer package.
| [root@server ~]# uname -i x86_64 |
Later on, run “cat /etc/redhat-release” to check the name & version of the OS installed on the system, for downloading the appropriate installer package.
| [root@server ~]# cat /etc/redhat-release CentOS release 5.2 (Final) |
Run the following 3 commands, to check if Apache, PHP & MySQL are preinstalled by the OS:
| [root@server ~]# rpm -qa | grep -i http [root@server ~]# rpm -qa | grep -i php [root@server ~]# rpm -qa | grep -i mysql |
If the above are found to be installed [most of the time they are] by the OS, they conflict with the applications Plesk installs, hence remove them using…
| [root@server ~]# yum remove http* [root@server ~]# yum remove php* [root@server ~]# yum remove mysql* |
Check SELinux status, we have it disabled but still… execute “getenforce” it should say “Disabled” or “Not enforcing“. If it’s enforcing, disable it by executing: “setenforce 0“.
| root@server [~]# getenforce Disabled |
Change your working directory to where you want to download the Auto-installer utility:
| [root@server ~]# mkdir /root/plesk [root@server ~]# cd /root/plesk |
Once done, download the Auto-installer utility that suits your operating system from HERE and save it on your server’s hard drive.
| eg : [root@server plesk]# wget plesk_auto_installer_file_name |
Set the execution permission for Auto-installer:
| eg : [root@server plesk]# chmod +x plesk_auto_installer_file_name |
Run the Auto-installer:
| eg : [root@server plesk]# ./plesk_auto_installer_file_name |
