1、前言
工作中伺服器有時候需要圖形處理一些事物，那麼這個時候就需要遠端連線方式，XDMCP,VNC,RDP，我今天介紹一下xdmp怎麼使用與配置（x display manager control protocol）
2、準備工作
centos 7主機
windows主機
保持網路互通
測試請關閉防火牆及selinux
3、linux上需要安裝lightdm
yum install lightdm

4、配置lightdm
備份：
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、更改預設顯示管理器，啟動服務
1 [[email protected] named]# systemctl disable gdm 2 Removed symlink /etc/systemd/system/display-manager.service. 3 [[email protected] named]# systemctl enable lightdm 4 Created symlink from /etc/systemd/system/display-manager.service to /usr/lib/systemd/system/lightdm.service. 5 [[email protected] named]# systemctl start lightdm
6、可以安裝xfce強兩級桌面環境
yum groupinstall xfce
小問題：有些人說groupinstall出錯，請檢查網路和epel源，我這裡也出錯後來發現是網路dns問題
可以先看看看yum grouplist 列表裡面有沒有xfce組
7、windows上開啟xstart 輸入配置，執行檢視效果
最後看一下 監聽埠，就是我們之前設定的177
1 [[email protected] 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 [[email protected] yum.repos.d]# vim /etc/
