## 在 CentOS6 下安装 gnome 桌面
    ```bash
    yum groupinstall 'X Window System'
    yum groupinstall Desktop
    sed -i '/^id/id:5:initdefault:' /etc/inittab
    ```

## 在 CentOS7 下安装 gnome3 桌面
    ```bash
    yum groupinstall 'X Window System'
    yum groupinstall 'Gnome Desktop'
    systemctl set-default graphical.target
    systemctl enable gdm
    # 创建一个可登陆的普通用户
    ```

## 在 gdm 中隐藏用户名
- 修改文件/etc/gdm/gdm.schemas，找到这一段：
    ```xml
    <schema>
    <key>greeter/Exclude</key>
    <signature>s</signature>
    <default>bin,root, daemon,adm,lp,sync,shutdown,halt,mail,news,uucp,operator,
    nobody,nobody4,noaccess,postgres,pvm,rpm,nfsnobody,pcap</default>
    </schema>
    ```
- 将用户名添加在<default>与</default>之间即可，用逗号隔开，保存退出即可。
