　x11vnc 整合至 systemd 开机自动执行

Nov.3,2022

设定密码

x11vnc 远端控制画面是传输XWindows整个画面，与其他的vnc server不同，在使用时建议一定要先设定密码做好最低限度的保护。

sudo x11vnc -storepasswd [你的密码] /etc/x11vnc.passwd

建立 Systemd Service档案

使用编辑器建立x11vnc.service，如：nano x11vnc.service

[Unit]
Description=VNC Server
After=multi-user.target network.target

[Service]
Restart=always
# Replace this with x0vncserver from TigerVNC in Ubuntu 18.04.
# Set password by running `sudo x11vnc -storepasswd [PASSWORD] /etc/x11vnc.passwd`
ExecStart=/usr/bin/x11vnc -auth guess -forever -loop -noxdamage -repeat -rfbauth /etc/x11vnc.passwd -rfbport 5900 -shared

[Install]
WantedBy=multi-user.target

存档后记住x11vnc.service的路径，等下会复制到对应的目录。

安装 Servce 档案至 Systemd

sudo cp [path to]/x11vnc.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable x11vnc.service

启动x11vnc

sudo systemctl start x11vnc

启动后查看一下执行是否正常

sudo systemctl status x11vnc

danny@EDY-G41MT-D3:~$ sudo systemctl status x11vnc
