　x11vnc 整合至 systemd 開機自動執行

Nov.3,2022

設定密碼

x11vnc 遠端控制畫面是傳輸XWindows整個畫面，與其他的vnc server不同，在使用時建議一定要先設定密碼做好最低限度的保護。

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

建立 Systemd Service檔案

使用編輯器建立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

存檔後記住x11vnc.service的路徑，等下會複制到對應的目錄。

安裝 Servce 檔案至 Systemd

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

啟動x11vnc

sudo systemctl start x11vnc

啟動後查看一下執行是否正常

sudo systemctl status x11vnc

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