树莓派 Ubuntu mate 18.04 VNC远程

树莓派 Ubuntu mate 18.04 VNC远程

VNC安装（x11vnc）

1. 安装

sudo apt install x11vnc -y

2. 密码配置

sudo x11vnc -storepasswd /etc/x11vnc.pass

3. 创建服务

sudo vi  /lib/systemd/system/x11vnc.service

4. 添加内容

[Unit]
Description=Start x11vnc at startup.
After=multi-user.target
[Service]
Type=simple
ExecStart=/usr/bin/x11vnc -auth guess -forever -loop -noxdamage -repeat -rfbauth /etc/x11vnc.pass -rfbport 5900 -shared
[Install]
WantedBy=multi-user.target

5. 防火墙

sudo ufw allow 5900
sudo systemctl enable x11vnc.service
sudo systemctl daemon-reload

6. 开机启动vnc

  在/etc/rc.local 文件中的exit 0前面添加：

sudo service x11vnc start  -geometry 1280×1024

7. 重启
8. 连接（使用vnc viewer）

附加： Ubuntu mate 18.04 不支持/etc/rc.local文件，因此还得做下面步骤：

1. 新建rc-local.service文件，并添加内容

sudo vi /etc/systemd/system/rc-local.service

[Unit]
Description=/etc/rc.local Compatibility
ConditionPathExists=/etc/rc.local
 
[Service]
Type=forking
ExecStart=/etc/rc.local start
TimeoutSec=0
StandardOutput=tty
RemainAfterExit=yes
SysVStartPriority=99
 
[Install]
WantedBy=multi-user.target

2. 创建rc.local文件并添加（上面做了，就省略这一步）

sudo vi /etc/rc.local

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
sudo service x11vnc start  -geometry 1280×1024
exit 0

3. 设置权限

sudo chmod +x /etc/rc.local

4. 启动服务

sudo systemctl enable rc-local
sudo systemctl start rc-local.service
sudo systemctl status rc-local.service
# Ps：显示active表示成功

PS：启动进入桌面，设置登录无需密码（设置—>用户与组—>高级设置）

面板设置：（setting—>login window）
