jitsi videobridges 集群如何配置？
当需要配置多个 jitsi-videobridges 时候 如何修改配置文件 呢？官网有这样的配置说明，但是并不知道括号里的内容具体如何配置，哪位大神帮帮我！！！
jitsi-videobridge2
You will need to adapt the following files (see the files in example-config-files/scalable)
Each videobridge will have to have it's own, unique nickname
/etc/jitsi/videobridge/config (hostname, password)
/etc/jitsi/jicofo/sip-communicator.properties (hostname of jitsi-meet, nickname of videobridge, vb_password)
