解决：Openstack创建实例进入控制台报错Something went wrong, connection is closed

如下图：Something went wrong, connection is closed 出现此样式

出现此问题的原因：openstack中 /usr/share/novnc/core/websock.js 此文件缺少binary或base64需要引入协议

解决方法：

1.修改配置文件

[root@openstack ~]# vim /usr/share/novnc/core/websock.js

230     open(uri, protocols) {
231         this.attach(new WebSocket(uri,['binary','base64']));   #修改此处，加入协议
232     }

2.重启服务验证（重启后需要清理浏览器缓存，然后重新访问）

[root@openstack ~]# systemctl restart openstack-nova-novncproxy.service
