如果服务器为centos7_minimal版本，则需要安装desktop（服务器系统为centos7_desktop则忽略）
yum groupinstall -y "GNOME Desktop"
关闭防火墙 systemctl stop firewalld systemctl disable firewalld [root@localhost ~]# firewall-cmd --state #查看防火墙是否关闭 not running
1.安装vnc server
yum install -y tigervnc-server tigervnc-server-module
2.复制vnc server的配置文件 vncserver@:1.service、vncserver@:2.service为连接不同的远程桌面，连接ip为ip:1、ip:2 (即为提供2个远程连接方式，VNC Server:ip:1、ip:2)
cp /lib/systemd/system/vncserver@.service /lib/systemd/system/vncserver@:1.service cp /lib/systemd/system/vncserver@.service /lib/systemd/system/vncserver@:2.service
3.修改vncserver@:1.service、vncserver@:2.service配置文件
[root@localhost ~]# vi /lib/systemd/system/vncserver@:1.service ... [Unit] Description=Remote desktop service (VNC) After=syslog.target network.target [Service] Type=forking # Clean any existing files in /tmp/.X11-unix environment ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :' #ExecStart=/usr/sbin/runuser -l <USER> -c "/usr/bin/vncserver %i" #use root to login --GUY_GO ExecStart=/usr/sbin/runuser -l root -c "/usr/bin/vncserver %i" #use root to login --GUY_GO #PIDFile=/home/<USER>/.vnc/%H%i.pid PIDFile=/root/.vnc/%H%i.pid ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :' [Install] WantedBy=multi-user.target
4.重新加载启动配置
systemctl daemon-reload
5.设置vnc server密码
[root@localhost ~]# vncpasswd Password: Verify: Passwords don't match - try again Password: [root@localhost ~]# vncpasswd Password: Verify: Would you like to enter a view-only password (y/n)? n A view-only password is not used
6.启动vnc server
[root@localhost ~]# vncserver #启动第一个远程桌面 New 'localhost.localdomain:1 (root)' desktop is localhost.localdomain:1 Starting applications specified in /root/.vnc/xstartup Log file is /root/.vnc/localhost.localdomain:1.log [root@localhost ~]# vncserver #启动第二个远程桌面 New 'localhost.localdomain:2 (root)' desktop is localhost.localdomain:2 Starting applications specified in /root/.vnc/xstartup Log file is /root/.vnc/localhost.localdomain:2.log [root@localhost ~]#
或使用以下命令启动
systemctl start vncserver@:1.service systemctl start vncserver@:2.service
7.关闭vncserver
pkill -9 vnc
或
systemctl stop vncserver@:1.service
8.使用VNC Viewer连接 windows下载vnc viewer并安装；
