NOVNC
1.客户端部署
-
运行下列命令安装vnc:
sudo apt-get install x11vnc -
生成密码
sudo x11vnc -storepasswd yourVNCpasswordHERE /etc/x11vnc.pass //生成密码 -
开机启动
//15.04+ 系统 sudo nano /lib/systemd/system/x11vnc.service //16.10+ 系统 sudo nano /etc/systemd/system/x11vnc.service -
在打开的页面中插入以下代码
[Unit] Description="x11vnc" Requires=display-manager.service After=display-manager.service [Service] ExecStart=/usr/bin/x11vnc -xkb -noxrecord -noxfixes -noxdamage -display :0 -auth guess -rfbauth /etc/x11vnc.pass ExecStop=/usr/bin/killall x11vnc Restart=on-failure Restart-sec=2 [Install] WantedBy=multi-user.target -
执行命令
sudo systemctl daemon-reload sudo systemctl start x11vnc -
确保在服务启动时启动
sudo systemctl enable x11vnc
2.服务端部署
- 在服务端机器上从Github将novnc下载
- 创建token.conf文件，写入客户端IP,格式：
test1: 192.168.11.239:5900 test1: 192.168.11.240:5900 //:后面必须有空格 - 启动novnc
./utils/websockify/websockify.py ./ --target-config=/home/ceeety/data/token/token.conf 8787
3. 连接测试
- 通过vnc_lite.html访问
- 打开拉取下来的项目中的vnc_lite.html文件,需要修改host、post、password、token
var host = WebUtil.getConfigVar('host', '192.168.11.241'); //服务端ip var port = WebUtil.getConfigVar('port', '8787'); //端口 var password = WebUtil.getConfigVar('password', 'ceeety'); //客户端密码 var token = WebUtil.getConfigVar('token', 'test'); //token.conf中客户端ip对应name - 运行vnc_lite.html页面,上一步没有修改密码时，需要输入密码。测试连接。
- 打开拉取下来的项目中的vnc_lite.html文件,需要修改host、post、password、token
- 通过vnc.html访问
- 运行vnc.html,在左侧填写连接信息，测试连接。
4. 集成
- 多客户端同时连接
| name | type | mode | default | description |
|---|---|---|---|---|
| target | DOM | WO | null | 用于渲染的画布元素(id) |
| encrypt | bool | RW | false | 使用TLS / SSL加密 |
| local_cursor | bool | RW | false | Request locally rendered cursor |
| shared | bool | RW | true | 请求共享VNC模式 |
| view_only | bool | RW | false | 仅监控，不能操作 |
| focus_on_click | bool | RW | true | 点击 |
| xvp_password_sep | str | RW | '@' | Separator for XVP password fields |
| disconnectTimeout | int | RW | 3 | 连接超时 |
| wsProtocols | arr | RW | ['binary'] | 使用 WebSocket connection |
| repeaterID | str | RW | '' | UltraVNC RepeaterID to connect to |
| viewportDrag | bool | RW | false | 鼠标拖动移动窗口 |

- 等比例缩放
在rfb.js中的 _resize: function(width, height) 方法中添加以下代码this._display.autoscale(540,192,1);
