Plesk simplifies web management activities to align with the way infrastructure is used today for hosting websites and web applications.
If you don’t have the latest version, please update your CentOS. We can simply do it with yum package installer.
yum update
Make sure that wget is installed. To do this, issue the following command in the server console:
yum install wget
Run Plesk installation with the following command:
wget -O - http://autoinstall.plesk.com/one-click-installer | sh
After installation has finished, you can log in to Plesk at the address:
https://<host-name-or-IP>:8443 using the username "root" and the root user's password.
