Posted 2021-01-23 乐章

　　工作中服务器有时候需要图形处理一些事物，那么这个时候就需要远程连接方式，XDMCP,VNC,RDP，我今天介绍一下xdmp怎么使用与配置（x display manager control protocol）

2、准备工作

　　centos 7主机

　　windows主机

　　保持网络互通

　　测试请关闭防火墙及selinux

3、linux上需要安装lightdm

　　yum install lightdm

56 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 
 5 
 6 #enabled=false
 7 #port=177
 8 #listen-address=
 9 #key=
10 #hostname=

 

5、更改默认显示管理器，启动服务

1 [root@node5 named]# systemctl disable gdm
2 Removed symlink /etc/systemd/system/display-manager.service.
3 [root@node5 named]# systemctl enable lightdm
4 Created symlink from /etc/systemd/system/display-manager.service to /usr/lib/systemd/system/lightdm.service.
5 [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

1 [root@web1 yum.repos.d]# ss -tunlop |grep 177 
2 udp    UNCONN     0      0         *:51773                 *:*                   users:(("dhclient",pid=124915,fd=20))
3 udp    UNCONN     0      0         *:177                   *:*                   users:(("lightdm",pid=125530,fd=11))
4 udp    UNCONN     0      0        :::177                  :::*                   users:(("lightdm",pid=125530,fd=12))
5 You have new mail in /var/spool/mail/root
6 [root@web1 yum.repos.d]# vim /etc/
