Selection of Linux

In general, if you want to do a server, choose CentOS or Ubuntu server, if you do desktop system, choose Ubuntu Desktop. But while learning about Hadoop, although the two systems are not very different, it is highly recommended to use the Ubuntu operating system.

System Installation Method

Choose a virtual machine or a dual-system Installation

There are two main ways to install a Linux system: Virtual machine Installation and dual system installation.

Because the virtual machine installation and the use of Linux hardware configuration is relatively high, it is recommended that the computer is newer or more than 4G configuration memory computer can choose the virtual machine installation, the computer is older or the configuration memory is less than or equal to 4G computer strongly recommends the choice of dual-system installation, otherwise, Running a Linux virtual machine on a low-profile computer can be very slow.
