一、安装VNC相关包
yum -y install tigervnc tigervnc-server tigervnc-server-module
二、复制配置模板文件为vncserver@:1.service
cp /lib/systemd/system/vncserver@.service /lib/systemd/system/vncserver@:1.service
三、修改/lib/systemd/system/vncserver@:1.service配置文件
[root@kvm01 ~]# cat /lib/systemd/system/vncserver\@\:1.service | grep -v ^# | grep -v ^$ [Unit] Description=Remote desktop service (VNC) After=syslog.target network.target [Service] Type=forking ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :' ExecStart=/usr/sbin/runuser -l root -c "/usr/bin/vncserver %i" PIDFile=/root/.vnc/%H%i.pid ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :' [Install] WantedBy=multi-user.target
四、设置VNC用户密码
vncpasswd
输入两次密码，完成密码设置
五、重新载入system配置
systemctl daemon-reload
六、启动vncserver@:1.service服务，并设置开机自启
systemctl start vncserver@:1.service && systemctl enable vncserver@:1.service
注：若系统无法正常关机，则再次启动，此服务无法启动，解决办法参照步骤七
七、问题解决
1.报错：Job for vncserver@:1.service failed because the control process exited with error code. See "systemctl status vncserver@:1.service" and "journalctl -xe" for details.
处理方法：
rm -rf /tmp/.X11-unix/*
