为方便使用vnc，所以寻找到一个比较好用的vnc服务端那就是x11vnc，索性就创建了一个系统进程
一、环境
系统：银河麒麟v4-sp2-server
软件：x11vnc【linux下】、VNCviewer【win下】
二、安装x11vnc
1、挂载光盘源并修改apt源
mount /dev/sr0 /mnt
vim /etc/apt/sources.list
deb [trusted=yes] file:///mnt juniper main
apt update
2、安装x11vnc
apt install x11vnc -y
# 到此就可以手动启动x11vnc了，可直接在终端执行x11vnx或者使用nohup后台运行
三、创建x11vnc系统进程
1、创建配置文件
vim /etc/systemd/system/x11vnc.service
[Unit]
Description=start x11vnc
After=syslog.target network.target
[Service]
Type=simple
ExecStart=/usr/bin/x11vnc -auth guess
[Install]
WantedBy=multi-user.target
2、保存配置并设置开机启动
systemctl daemon-reload
systemctl enable x11vnc.service
四、查看使用
systemctl start x11vnc.service
root@Kylin:~# systemctl status x11vnc
● x11vnc.service - start x11vnc
Loaded: loaded (/etc/systemd/system/x11vnc.service; enabled; vendor preset: enabled)
