 Complete!

4、配置lightdm

　　备份：

　　cp /etc/lightdm/lightdm.conf{,.backup}

　　vim /etc/loghtdm/lightdm.conf

　　

 1 [XDMCPServer]
 2 enabled=true
 3 port=177
 4 

 #enabled=false
 #port=
 #listen-address=
 #key=
 #hostname=

5、更改默认显示管理器，启动服务

 [root@node5 named]# systemctl disable gdm
 Removed symlink /etc/systemd/system/display-manager.service.
 [root@node5 named]# systemctl enable lightdm
 Created symlink from /etc/systemd/system/display-manager.service to /usr/lib/systemd/system/lightdm.service.
 [root@node5 named]# systemctl start lightdm

6、可以安装xfce强两级桌面环境

　　yum groupinstall xfce

　　小问题：有些人说groupinstall出错，请检查网络和epel源，我这里也出错后来发现是网络dns问题

　　可以先看看看yum grouplist  列表里面有没有xfce组

7、windows上打开xstart 输入配置，运行查看效果

　　

　　

　　

最后看一下 监听端口，就是我们之前设置的177

 [root@web1 yum.repos.d]# ss -tunlop |grep
 udp    UNCONN                    *:                 *:*                   users:(("dhclient",pid=,fd=))
3 udp    UNCONN     0      0         *:177                   *:*                   users:(("lightdm",pid=125530,fd=11))
4 udp    UNCONN     0      0        :::177                  :::*                   users:(("lightdm",pid=125530,fd=12))
 You have new mail in /var/spool/mail/root
 [root@web1 yum.repos.d]# vim /etc/
