一、实验环境
操作系统：CentOS7.3 桌面版
用户： 管理员root、普通用户Michael
二、安装 VNC server
# yum -y install epel-release
# yum -y install tigervnc-server
三、配置
VNC server
# cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:1.service
# cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:2.service
# vim /etc/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 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、设置密码
# vncserver
# su - Michael
$ vncserver
.
注：设置和修改密码，需切换到相应用户，第一次设置密码用 vncserver，以后如果需要修改密码，用 vncpasswd
五、 启动服务
# systemctl daemon-reload
# systemctl enable vncserver@:1.service
# systemctl enable vncserver@:2.service
# systemctl start vncserver@:1.service
# systemctl start vncserver@:2.service
# systemctl status vncserver@:1.service
# systemctl status vncserver@:2.service
六、设置防火墙
# systemctl start firewalld
# systemctl enable firewalld
# firewall-cmd --permanent --add-service vnc-server
# firewall-cmd --reload
