How Can I Install a GUI on an ECS Running CentOS 6?

Scenarios

To provide a pure system, the ECSs running CentOS 6 do not have a GUI installed by default. You can install a GUI on such ECSs as needed.

Constraints

  • Before installing a GUI on an ECS, ensure that the idle memory is greater than or equal to 2 GB. Otherwise, the GUI installation may fail or the ECS cannot be started after the installation.

Procedure

  1. Run the following command to obtain the installation component provided by the OS:

    yum groupinstall "Desktop"

  1. Run the following command to set the default startup level to 5 (GUI):

    sed -i 's/id:3:initdefault:/id:5:initdefault:/' /etc/inittab

  2. Run the following command:

    startx
