Control Panel for Linux

Choosing a control panel for your server is like picking a lock at a locksmith. Your house would be as secured as the lock is. And that too is true for your server in terms of getting a control panel.

In this day and age of technology, you can get a dedicated VPS for as low as $5. We have been in the Linux administration business for little over 8 years now and can safely share some of our thoughts that might come in handy.


What is a control panel?

In a lame term, a linux control panel is a software running on your hardware. It should have a web server, a database server, file server, FTP server and a solid security.


What we use?

We have been using cPanel for a while now. They offer 14-days free trial which is sufficient to setup your server.

In order to set-up your server here is what you need.

  • Pick Cent OS
  • Install Cent OS
  • follow these commands
    • cd /home/
    • yum install perl
    • yum update
    • wget -N http://httpupdate.cpanel.net/latest
    • sh latest
That last command will take long time. About 45 minutes to up-to 2 hours
