SRS可以将送到SRS的流转发给其他RTMP服务器,实现简单集群/热备功能,也可以实现一路流热备(譬如编码器由于带宽限制,只能送一路流到RTMP服务器,要求RTMP服务器能将这路流也转发给其他RTMP备用服务器,实现主备容错集群)。
Suppose the server ip is 192.168.1.170
Forward就是SRS将流拷贝输出给其他的RTMP服务器,以SRS转发给SRS为例:
- 主SRS:Master, 编码器推流到主SRS,主SRS将流处理的同时,将流转发到备SRS
- 备SRS:Slave, 主SRS转发流到备SRS,就像编码器推送流到备用SRS一样。 我们的部署实例中,主SRS侦听1935端口,备SRS侦听19350端口。
Step 1, get SRS. For detail, read GIT
git clone https://github.com/winlinvip/simple-rtmp-server
cd simple-rtmp-server/trunk
Or update the exists code:
git pull
Step 2, build SRS. For detail, read Build
./configure --disable-all --with-ssl && make
第三步,编写主SRS配置文件。 For detail, read Cluster
将以下内容保存为文件,譬如conf/forward.master.conf
,服务器启动时指定该配置文件(srs的conf文件夹有该文件)。
# conf/forward.master.conf
listen 1935;
max_connections 1000;
pid ./objs/srs.master.pid;
srs_log_tank file;
srs_log_file ./objs/srs.master.log;
vhost __defaultVhost__ {
forward 127.0.0.1:19350;
}
第四步,启动主SRS,主SRS将流转发到备SRS。 For detail, read Cluster
./objs/srs -c conf/forward.master.conf
第五步,编写备SRS配置文件。 For detail, read Cluster
将以下内容保存为文件,譬如conf/forward.slave.conf
,服务器启动时指定该配置文件(srs的conf文件夹有该文件)。
# conf/forward.slave.conf
listen 19350;
pid ./objs/srs.slave.pid;
srs_log_tank file;
srs_log_file ./objs/srs.slave.log;
vhost __defaultVhost__ {
}
第六步,启动备SRS,主SRS将流转发到备SRS。 For detail, read Cluster
./objs/srs -c conf/forward.slave.conf
注意:启动srs后查看下srs是否启动成功,错误可以查看日志。
[winlin@dev6 srs]$ sudo netstat -anp|grep srs
tcp 0 0 0.0.0.0:1935 0.0.0.0:* LISTEN 7826/srs
tcp 0 0 0.0.0.0:19350 0.0.0.0:* LISTEN 7834/srs
第七步,启动推流编码器。 For detail, read Cluster
使用FFMPEG命令推流:
for((;;)); do \
./objs/ffmpeg/bin/ffmpeg -re -i ./doc/source.200kbps.768x320.flv \
-vcodec copy -acodec copy \
-f flv -y rtmp://192.168.1.170/live/livestream; \
sleep 1; \
done
或使用FMLE推流:
FMS URL: rtmp://192.168.1.170/live
Stream: livestream
涉及的流包括:
- 编码器推送的流:rtmp://192.168.1.170/live/livestream
- 主SRS转发的流:rtmp://192.168.1.170:19350/live/livestream
- 观看主SRS的流:rtmp://192.168.1.170/live/livestream
- 观看备SRS的流:rtmp://192.168.1.170:19350/live/livestream
第八步,观看主SRS的RTMP流。 For detail, read Cluster
RTMP url is: rtmp://192.168.1.170:1935/live/livestream
User can use vlc to play the RTMP stream.
Or, use online SRS player: http://winlinvip.github.io/srs.release/trunk/research/players/srs_player.html?vhost=defaultVhost&autostart=true&server=192.168.1.170&app=live&stream=livestream&port=1935
Note: Please replace all ip 192.168.1.170 to your server ip.
第九步,观看备SRS的RTMP流。 For detail, read Cluster
RTMP url is: rtmp://192.168.1.170:19350/live/livestream
User can use vlc to play the RTMP stream.
Or, use online SRS player: http://winlinvip.github.io/srs.release/trunk/research/players/srs_player.html?vhost=defaultVhost&autostart=true&server=192.168.1.170&app=live&stream=livestream&port=19350
Note: Please replace all ip 192.168.1.170 to your server ip.
