在Centos7上安装VNC Server

# 安装

[root@bigdata-dev ~]# yum install -y tigervnc-server

首先查看原来的默认配置
[root@bigdata-dev ~]# cat /lib/systemd/system/vncserver@.service 

[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"
PIDFile=/home/<USER>/.vnc/%H%i.pid
ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'

复制一份修改，已root用户为例。其他用户类推
[root@bigdata-dev system]# cp vncserver@.service vncserver@:1.service 
[root@bigdata-dev system]# vi vncserver@\:1.service 

[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 || :'
