HLS Edge Cluster Example

Example for HLS Edge Cluster, like to create a CDN to deliver HLS files.

Suppose the server ip is 192.168.1.170

Step 1, Get SRS code​

For detail, read GIT

git clone https://github.com/ossrs/srs
cd srs/trunk

Or update the exists code:

git pull

Step 2, Configure and build SRS​

For detail, read Build

./configure && make

Step 3, Config origin srs, to generate HLS files​

See HLS.

Please use config conf/hls.origin.conf, or create a config file by:

# conf/hls.origin.conf
listen 1935;
max_connections 1000;
daemon off;
srs_log_tank console;
http_server {
enabled on;
listen 8080;
}
vhost __defaultVhost__ {
hls {
enabled on;
}
}

Step 4, Config edge NGINX to deliver HLS files.​

See Nginx for HLS.

Save bellow as config, or use conf/hls.edge.conf:

# conf/hls.edge.conf
worker_processes 3;
events {
worker_connections 10240;
}

http {
# For Proxy Cache.
proxy_cache_path /tmp/nginx-cache levels=1:2 keys_zone=srs_cache:8m max_size=1000m inactive=600m;
proxy_temp_path /tmp/nginx-cache/tmp;

server {
listen 8081;
# For Proxy Cache.
proxy_cache_valid 404 10s;
proxy_cache_lock on;
proxy_cache_lock_age 300s;
proxy_cache_lock_timeout 300s;
proxy_cache_min_uses 1;

location ~ /.+/.*\.(m3u8)$ {
proxy_pass http://127.0.0.1:8080$request_uri;
# For Proxy Cache.
proxy_cache srs_cache;
proxy_cache_key $scheme$proxy_host$uri$args;
proxy_cache_valid 200 302 10s;
}
location ~ /.+/.*\.(ts)$ {
proxy_pass http://127.0.0.1:8080$request_uri;
# For Proxy Cache.
proxy_cache srs_cache;
proxy_cache_key $scheme$proxy_host$uri;
proxy_cache_valid 200 302 60m;
}
}
}

Step 5, Start SRS Origin and NGINX Edge Server​

nginx -c $(pwd)/conf/hls.edge.conf
./objs/srs -c conf/hls.origin.conf

Note: Please follow instructions of NGINX to download and install.

Step 6, Publish RTMP stream to SRS Origin, to generate HLS files.​

Use FFMPEG to publish stream:

for((;;)); do \
./objs/ffmpeg/bin/ffmpeg -re -i ./doc/source.flv \
-c copy -f flv rtmp://192.168.1.170/live/livestream; \
sleep 1; \
done

Or use OBS to publish:

Server: rtmp://192.168.1.170/live
StreamKey: livestream

Step 7, Play HLS stream​

HLS by SRS Origin: http://192.168.1.170:8080/live/livestream.m3u8

HLS by NGINX Edge: http://192.168.1.170:8081/live/livestream.m3u8

Note: Please replace all ip 192.168.1.170 to your server ip.

Step 8: Benchmark and More NGINX Edge Servers​

Please use srs-bench to simulate a set of visitors:

docker run --rm -it --network=host --name sb ossrs/srs:sb \
./objs/sb_hls_load -c 100 -r http://192.168.1.170:8081/live/livestream.m3u8

You could run more NGINX from another server, use the same config.
