# 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.md)
|
|
|
|
```bash
|
|
git clone https://github.com/ossrs/srs
|
|
cd srs/trunk
|
|
```
|
|
|
|
Or update the exists code:
|
|
|
|
```bash
|
|
git pull
|
|
```
|
|
|
|
## Step 2, Configure and build SRS
|
|
|
|
For detail, read [Build](./install.md)
|
|
|
|
```bash
|
|
./configure && make
|
|
```
|
|
|
|
## Step 3, Config origin srs, to generate HLS files
|
|
|
|
See [HLS](./hls.md).
|
|
|
|
Please use config `conf/hls.origin.conf`, or create a config file by:
|
|
|
|
```bash
|
|
# 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;
|
|
hls_ctx off;
|
|
hls_ts_ctx off;
|
|
}
|
|
}
|
|
```
|
|
|
|
## Step 4, Config edge NGINX to deliver HLS files.
|
|
|
|
See [Nginx for HLS](./nginx-for-hls.md).
|
|
|
|
Save bellow as config, or use `conf/hls.edge.conf`:
|
|
|
|
```bash
|
|
# 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
|
|
|
|
```bash
|
|
nginx -c $(pwd)/conf/hls.edge.conf
|
|
./objs/srs -c conf/hls.origin.conf
|
|
```
|
|
|
|
> Note: Please follow instructions of [NGINX](https://nginx.org/) to download and install.
|
|
|
|
## Step 6, Publish RTMP stream to SRS Origin, to generate HLS files.
|
|
|
|
Use FFMPEG to publish stream:
|
|
|
|
```bash
|
|
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:
|
|
|
|
```bash
|
|
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](https://github.com/ossrs/srs-bench#usage) to simulate a set of visitors:
|
|
|
|
```bash
|
|
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.
