novnc：出了点问题，连接已关闭

Question

我无法将vm与novnc连接起来。

我正在玩带有两个节点的openstack。现在，我创建了一个虚拟机，并希望将其与novnc连接。我使用命令nova --os-region-name=RegionOne get-vnc-console vm1 novnc获取VM1 novnc URL。我在Firefox上使用它。 但是它表明something went wrong,connection is closed：

我使用"nova --os-region-name=RegionOne get-vnc-console vm1 novnc来获取虚拟机的novnc网址。

我想用noc连接我的vm，但是不能。 它显示something went wrong,connection is closed。

Answer 1

使用命令vncserver从终端启动novnc。稍后，刷新浏览器。

Answer 2

我遇到了同样的问题，并且解决了。

您也许可以在openstack控制器/var/log/nova/nova-novncproxy.log中找到关注消息

原因：未在/ etc / hosts中写入 comp1.ap-southeast-1.compute.internal

解决：在主机中添加别名

  3: connect info: ConsoleAuthToken(access_url_base='http://10.0.0.10:6080/vnc_auto.html'
  3: connecting to: comp1.ap-southeast-1.compute.internal:5900
 handler exception: [Errno -2] Name or service not known

顺便说一句，我不明白为什么vncproxy突然尝试通过IP地址中的主机名进行连接。 ：p
