# 如何设置VNC远程访问 novnc python-websockify 

使用root账户登录并执行下列操作：

## 安装VNC

```shell
apt update; sudo apt installtightvncserver -y
```

### 设置root用户VNC密码

```shell
vncserver
You will require a password to access your desktops.
Password:  # 设置你的root账户的VNC访问密码
Verify:    # 再次确认你的root账户的VNC访问密码
## 下面设置仅查看密码(无操作权限)，这里不设置，所以选择"n"
Would you like to enter a view-only password (y/n)? n 
```

### 结束VNC进程

```shell
vncserver -kill :1
```

### 设置root账户VNC配置文件

```shell
mv /root/.vnc/xstartup /root/.vnc/xstartup.bak
## 编辑文件
vim /root/.vnc/xstartup
## 键入下面的内容
```

```shell
#!/bin/bash
xrdb $HOME/.Xresources
startxfce4 &
```

### 启动检验再关闭退出

```shell
vncserver ; vncserver -kill :1
```

### 设置pi账户VNC配置文件

```shell
mkdir /home/pi/.vnc ; cp ~/.vnc/xstartup /home/pi/.vnc/xstartup ;\
chown -R  pi /home/pi/.vnc ;\
adduser pi bluetooth
```

```shell
## 编辑文件

vim /etc/dbus-1/system.d/bluetooth.conf

#### 在"<!-- allow users of bluetooth group to communicate -->" 一行上加入以下内容
```

```shell

  <policy group="pi">
    <allow send_destination="org.bluez"/>
  </policy>

## 下面一行不要添加，文件中应该存在
<!-- allow users of bluetooth group to communicate -->
```
