Today we use virtualization for both development, testing and also production. One of the most popular virtualization solution is VMware. There are many products that we can use for free such as VMware Player or VMware vSphere Hypervisor (ESXi).

Or in Linux Server that don't have GUI, Host OS can read or change some value from Guest OS such as IP Address.

Install VMware Tools on Windows OS will be very easy as install normal software. But this article will help you to install VMware Tools on Linux Server that have only CLI for you. In principle you must have compiler and linux headers so you can go smooth with installing VMware Tools.

My opinion: Choosing Distro for Linux Server

As you can see in my resume. I has been playing many linux distro for long time including FreeBSD Unix. So I want to share my opinion about choosing Linux Distro for server role.

  • If I want the most stable server but not install on virtualization system, I choose FreeBSD (that very difficult to install and config)
  • If I want normal stable server with ease to install software including I want to create the test server and can be install on virtualization system, I choose Debian
  • If I want to play new toys and I can accept nearly stable server, frequent restart, I choose Ubuntu
  • I never use CentOS and Redhat expect the software that I want to install required Redhat based OS such as cPanel

The reason that I always choose Debian based distro because I love APT more than YUM :)

PS. For the linux desktop I choose Ubuntu because I used it for long time and I getting into it.
