red5单机还是比较不错的，但是官方网站没有文档，不知道集群怎么配置，网查找了半天，只有red5 0.8版本有集群配置。以后的版本看了一下，有集群的插件，但是不知道怎么装插件，就算装好了插件，怎么配置集群，还是不知道啊。没文档坑爹。
crtmpserver 流媒体服务器，研究学习，感觉还是不错的，下面说一下，集群配置。
一，crtmpserver下载
https://github.com/j0sh/crtmpserver
二，服务器说明
192.168.10.208 主服务器
192.168.10.202 从服务器
三，主从服务器安装crtmpserver
1，安装相关依赖包
# yum install cmake openssl openssl-devel gcc gcc-c++ make
2，安装crtmpserver
# unzip centosinit.zip
# cd crtmpserver-centosinit
# chmod +x cleanup.sh
# sh cleanup.sh
# cd builders/cmake
# cmake .
# make
3，主服务器208配置
# vim ./crtmpserver/crtmpserver.lua
{ //85行，acceptors加入，rtmp可以使用80端口。如果80有其他用处，就不要这样设置了
ip="0.0.0.0",
port=80,
protocol="inboundRtmp"
},
name="proxypublish", //256行，配置集群的地方
description="Application for forwarding streams to another RTMP server",
protocol="dynamiclinklibrary",
acceptors = //相当于一个连接池
{
{
ip="0.0.0.0",
port=6665, //连接池的端口
protocol="inboundRtmp" //添加
--protocol="inboundLiveFlv" //--注释原来的
},
},
abortOnConnectError=true,
targetServers =
{
{
targetUri="rtmp://192.168.10.208/live/", //实际rtmp服务器
targetStreamType="live",
localStreamName="test",
keepAlive=true,
emulateUserAgent="my master"
},
{
targetUri="rtmp://192.168.10.202:1935/live/", //实际的rtmp服务器
targetStreamType="live",
emulateUserAgent="My user agent",
localStreamName="test",
keepAlive=true
}
}
注意，crtmpserver默认占用8080，8081，有的http会占用这二个端口。端口冲突的话，crtmpserver是启不来的。
4，从服务器默认配置就行了，当然你想做一特殊配置也是可以的。
四，启动主从服务器
# ./crtmpserver/crtmpserver ./crtmpserver/crtmpserver.lua
//出现以下内容说明启动成功了

注意，先启动从服务器，这一点很重要。
五，测试crtmpserver集群配置，以下安装在主服务器208
1，安装rpmforge
# rpm -ivh http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm
根你的linux版本选择
2，安装ffmpeg
# yum install ffmpeg
3，利用ffmpeg发布rtmp流
# ffmpeg -re -i "/root/test.flv" -vcodec copy -acodec copy -f flv rtmp://192.168.10.208:6665/live/test //连接池端口

4，接收rtmp流，网上工具好多，就不多说了
rtmp://192.168.10.208:6665/live/test
rtmp://192.168.10.208/live/test
rtmp://192.168.10.202:1935/live/test
以上三个rtmp通道，都可以看ffmpeg发布的视频流
