OriginCluster

Design

关于源站集群的设计参考Issue#464.

Remark: 源站集群只支持RTMP协议，如果需要HTTP-FLV，可以加一个Edge将RTMP转成HTTP-FLV。

Config

源站集群的配置如下：

vhost __defaultVhost__ {
    # The config for cluster.
    cluster {
        # The cluster mode, local or remote.
        #       local: It's an origin server, serve streams itself.
        #       remote: It's an edge server, fetch or push stream to origin server.
        # default: local
        mode            local;

        # For origin(mode local) cluster, turn on the cluster.
        # @remark Origin cluster only supports RTMP, use Edge to transmux RTMP to FLV.
        # default: off
        # TODO: FIXME: Support reload.
        origin_cluster      on;

        # For origin (mode local) cluster, the co-worker's HTTP APIs.
        # This origin will connect to co-workers and communicate with them.
        # please read: https://github.com/ossrs/srs/wiki/v3_CN_OriginCluster
        # TODO: FIXME: Support reload.
        coworkers           127.0.0.1:9091 127.0.0.1:9092;
    }
}

其中：

• mode: 集群的模式，对于源站集群，值应该是local。
• origin_cluster: 是否开启源站集群。
• coworkers: 源站集群中的其他源站。

Usage

源站集群的用法参考#464。

推荐在源站集群前面挂一系列的Edge服务器，参考这里，Edge服务器可以转换协议，支持RTMP和HTTP-FLV，同时支持源站故障时自动切换，不中断客户端。
