I’m installing a Plesk on a virtual machine, in a fresh CentOS.

For non-fresh CentOS  or with f Apache, PHP, MySQL and/or Cyrus, remove them.

yum remove http* 
yum remove php* 
yum remove cyrus* 
yum remove mysql*

1. Disable SELinux status

setenforce 0

3. Make a working directory and go inside her 😉

mkdir /root/plesk
cd /root/plesk

4. Download the plesk auto installer

wget http://autoinstall.plesk.com/plesk-installer

5. Run it

 sh ./plesk-installer

Now is just follow the screens! 🙂

 Congratulations!
 All stages of the installation/upgrade have been finished.
 psa is now running on your system.
 To complete the system configuration process, please proceed to URL:
