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
