OriginCluster

Design

About the design of Origin Cluster, please read the Issue#464.

Remark: Origin cluster only supports RTMP, use Edge to transmux RTMP to FLV.

Config

The config for origin cluster:

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_EN_OriginCluster
        # TODO: FIXME: Support reload.
        coworkers           127.0.0.1:9091 127.0.0.1:9092;
    }
}

• mode: The mode of cluster, it should be local for origin cluster.
• origin_cluster: Whether enable origin cluster.
• coworkers: The HTTP APIs of other origin servers in the cluster. The HTTP API response message includes whether owns the stream, and the stream information. Server response failed when stream does not exist in all origin servers.

Usage

To use origin cluster, please read #464.

We also recommend to use a edge server please read here. The edge server can transmux RTMP to HTTP-FLV, supports fault-tolerance.
