Enabling Power User UI
The power user interface combines the simplicity of Parallels Small Business Panel and powerful hosting management features of Parallels Plesk Panel product line. It is intended for users who do not need functions for reselling shared hosting services and accommodating new resellers and customers:
* There is no hierarchy of user accounts specific to shared hosting: no resellers, no customers.
* There are no service plans, subscriptions, and limits on amounts of resources consumed by websites.
To enable the power user mode through the Panel command line:
On Linux systems, issue the command:
/usr/local/psa/bin/poweruser –on -ip [ip-address>] -domain [domain_name>]
where
* [ip-address] is the IP address allocated to the administrator’s default webspace.
This option is required in case there are no subscriptions belonging to admin.
* [domain_name] is the name of the default webspace and the main website in this webspace. If the -domain option is not specified, the server host name will be used. The option makes sense only when used together with -ip.

Enabling or disabling SuExec in WHM
SuExec is an Apache feature that gives users the ability to run CGI and SSI programs using user IDs that are different from the user ID of the calling web server. This effectively means that CGI and SSI programs will not have access to the root account or have root permissions.
To enable or disable SuExec:
1.Click on the Enable/Disable SuExec link in the Server Setup menu.
2.Click on the Enable button to enable SuExec or click on the Disable button to disable SuExec.
suEXEC is based on a setuid “wrapper” program that is called by the main Apache web server. This wrapper is called when an HTTP request is made for a CGI or SSI program that the administrator has designated to run as a userid other than that of the main server. When such a request is made, Apache provides the suEXEC wrapper with the program’s name and the user and group IDs under which the program is to execute.
Enabling DNS clustering on each server
A DNS cluster is a number of nameservers that share records. To optimally configure your DNS cluster, you will need 2 spare servers, both preferably running cPanel DNS ONLY. You will also need at least 1 web server with cPanel/WHM installed.
You can download the cPanel DNS ONLY software here.
http://layer1.cpanel.net/cpanel-dnsonly-install.sea
All machines in the cluster must be running cPanel or cPanel DNS ONLY version 11 or higher. Some features may not work with older versions of cPanel.
Enabling DNS clustering on each server
First, you will need to enable DNS clustering via each server’s WHM interface.
1. Navigate to WHM’s Configure Cluster screen.
2. Click Enable Dns Clustering.
3. Click Change.
4. Click Return to Cluster Status.
Next, you will need to specify which server(s) you wish to cluster, or share DNS information with.
You do not need to link dedicated DNS servers to each other, or link dedicated web servers to each other.
You will need to sync each web server to its DNS servers.
You should not set a DNS server to sync data back to a web server, as this will put extraneous data on the web server.
Enabling the additional Plesk add-on
There are many feature that can be added on to your Plesk install such as Help Desk, Dr. Web, etc… these features are not available in the default install, but you can easily activate then by buying them from parallels.com.
1. Log into Plesk
2. Click “Server” on the left hand side
3. Click the “License Management” icon
4. Click the “Order Control Panel Add-Ons” icon
