OpenStack 虚拟机实例打开 noVNC 控制台失败

当前情况

OpenStack train 4.0.2

报错信息：
cat /var/log/nova/nova-novncproxy.log

code 400, message Client must support 'binary' or 'base64' protocol

查看当前版本：

[root@controller ~]# nova-novncproxy --version
20.6.0
[root@controller ~]# yum list | grep novnc
novnc.noarch                             1.3.0-5.el7                   @epel    
openstack-nova-novncproxy.noarch         1:20.6.0-1.el7                @train

[root@controller ~]# rpm -qa | grep websockify
python36-websockify-0.6.0-5.el7.noarch
python2-websockify-0.8.0-13.el7.noarch

解决办法

网上普遍的一个解决办法，尝试编辑文件/usr/share/novnc/core/websock.js，将

open(uri, protocols) {
    this.attach(new WebSocket(uri, protocols));
}

替换为

open(uri, protocols) {
    this.attach(new WebSocket(uri, ['binary', 'base64']));
}

重启服务

systemctl restart openstack-nova-conductor.service openstack-nova-novncproxy.service openstack-nova-scheduler.service

验证是否解决（注意：需要重新生成带 token 的 noVNC 链接）

[root@controller ~]# openstack console url show testVM1
