vncserver 安装、自启动、安全

安装

        yum install -y tigger-vncserver

        vncserver  -list --all

        vncserver    :1

自启动

        cd /etc/systemd/system/

        cp /usr/lib/systemd/system/vncserver@.service   vncserver@:1.service

        cp /usr/lib/systemd/system/vncserver@.service  vncserver@:2.service

        cp /usr/lib/systemd/system/vncserver@.service  vncserver@:3.service

编辑配置文件(vncserver@:1.service)中

#
# Quick HowTo:
# 1. Copy this file to /etc/systemd/system/vncserver@.service
# 2. Replace  with the actual user name and edit vncserver
#    parameters in the wrapper script located in /usr/bin/vncserver_wrapper
# 3. Run `systemctl daemon-reload`
# 4. Run `systemctl enable vncserver@:.service`
#
# DO NOT RUN THIS SERVICE if your local area network is
# untrusted!  For a secure way of using VNC, you should
# limit connections to the local host and then tunnel from
# the machine you want to view VNC on (host A) to the machine
# whose VNC output you want to view (host B)
