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

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.

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.

Run the following command to obtain the installation component provided by the OS:
```
yum groupinstall "Desktop"
```

Run the following command to set the default startup level to 5 (GUI):
```
sed -i 's/id:3:initdefault:/id:5:initdefault:/' /etc/inittab
```
Run the following command:
```
startx
```
After the command is executed, a GUI is displayed.
