Nginx+RTMP 直播服务器集群

Nginx+RTMP

直播服务器集群

1 直播服务器搭建

1.1 系统环境

操作系统：Centos7.3

系统版本：CentOS Linux release 7.3.1611 (Core)

Nginx 版本：1.12

1.2 RTMP 模块安装

Git clone

添加到 Nginx 模块中编译 --add-module

例如：

上图表明系统 Nginx 已经加载了 RTMP 模块

注意，如果需要支持 H.264，需额外安装 nginx_mod_h264_streaming 模块

wget

需要注释掉 nginx_mod_h264_streaming-

2.2.7/src/ngx_http_streaming_module.c 的以下内容：

if (r->zero_in_uri)

{

return NGX_DECLINED;

}

如上图表明已经加载 h264 模块

1.3 配置 RTMP

在 Nginx 中配置

rtmp { server {

listen 1935; application myapp {

live on;

}

record all; record_path /tmp/av;

record_suffix %Y%m%d%H%M%S.mp4; record_unique on;

record_append on;

}

参数简要说明：

record

录制相关

· off - 不记录在所有

· all - 音频和视频（一切）

· audio -音频

· video - 视频

· keyframes -唯一的关键帧视频

· manual - 从来没有自动启动记录仪，使用控制界面来启动/停止

record_path

指定录制文件的路径

record_suffix

录制文件的格式

语法: record_suffix value

该参数默认为 Flv 格式，即不定义的话录制文件格式为.Flv

record_suffix %Y%m%d%H%M%S.mp4 表示录制文件为 mp4 格式

record_unique

是否打开追加当前的时间戳，默认为 off

record_append

切换文件追加模式以上

application appname {

……

}

配置完成后，重启 nginx，即可进行推拉流测试

例如：推流地址 rtmp://localhost:1935/myapp/teststream1

拉流地址 rtmp://localhost:1935/myapp/teststream1

1.4 配置 HLS

rtmp { server {

listen 1935;

application hls { live on;

hls on;

hls_path /tmp/hls;

record all;

record_path /usr/local/nginx/html/liverecord; record_suffix %Y%m%d%H%M%S.mp4; record_unique on;

hls_fragment 4s; hls_playlist_length 12s; hls_nested on; hls_cleanup off;

hls_fragment_naming system; wait_key on;

sync 10ms;

}

http{ server {

listen 8008; server_name localhost; location /hls {

types {

application/vnd.apple.mpegurl m3u8; video/mp2t ts;

}

root /tmp;

add_header Cache-Control no-cache;

}

参数说明：

hls on; 表示打开回看（HLS）

hls_path; hls 文件路径，即.m3u8 以及 ts 切片文件路径

完成以上 rtmp{……} 及 http {……} 配置后，即可进行推拉流例如：

推流地址： rtmp://localhost:1935/hls/mystream1

拉流地址： rtmp://localhost:8008/hls/mystream1/index.m3u8

2 直播服务器转推集群

2.1 集群配置

Nginx+RTMP 可以实现直播、点播，但单机性能有限，就需要集群。本方案采用

RTMP 推流服务器公用，辅助多节点代理服务器，用户通过节点拉流请求代理转发到推流服务器。

配置示例如下：

推流服务器 A 配置（192.168.1.152）（192.168.1.182）：

rtmp {

server {

listen 1935;

chunk_size 4000;

application myapp { live on;

record all; record_path /tmp/av; record_suffix .mp4; record_unique on; record_append on;

push rtmp://192.168.1.176:1935/myapp; push rtmp://192.168.1.183:1935/myapp;

}

application hls {

live on; hls on;

hls_path /tmp/hls; record all;

record_path /usr/local/nginx/html/liverecord; record_suffix %Y%m%d%H%M%S.mp4; record_unique on;

hls_fragment 4s; hls_playlist_length 12s; hls_nested on; hls_cleanup off;

hls_fragment_naming system; wait_key on;

sync 10ms;

push rtmp://192.168.1.176:1935/hls; push rtmp://192.168.1.183:1935/hls;

}

http{

server {

listen 8008; location /hls {

# Serve HLS fragments types {

application/vnd.apple.mpegurl m3u8; video/mp2t ts;

}

root /tmp;

add_header Cache-Control no-cache;

}

拉流服务器（192.168.1.176）、（192.168.1.183）：

rtmp {

server {

listen 1935;

chunk_size 4000;

application myapp {

# enable live streaming live on;

}

application hls { live on;

hls on;

hls_path /tmp/hls; hls_fragment 4s; hls_playlist_length 12s; hls_nested on; hls_cleanup off;

hls_fragment_naming system; wait_key on;

sync 10ms;

}

http {

server {

listen 8080; location /hls {

# Serve HLS fragments types {

application/vnd.apple.mpegurl m3u8; video/mp2t ts;

}

root /tmp;

add_header Cache-Control no-cache;

}

RTMP 流：

推流：rtmp://192.168.1.152:1935/live/stream1

对应拉流地址：

rtmp://192.168.1.152:1935/live/stream1 （本地拉流）

rtmp://192.168.1.176:1935/live/stream1 （拉流）

HLS 流：

推流：rtmp://192.168.1.152:1935/hlslive/stream2

对应拉流地址：

http://192.168.1.152:8008/hlslive/stream2/index.m3u8 （本地拉流）

:8080/hlslive/stream2/index.m3u8 （代理节点拉流）

2.2 集群测试

在推流服务器上使用 OBS 推流，然后在拉流服务器上通过 VLC 拉流

RTMP 推流地址：

rtmp://192.168.1.152:1935/myapp/mystream1

RTMP 拉流地址：

rtmp:// 192.168.1.176:1935/myapp/mystream1 rtmp:// 192.168.1.183:1935/myapp/mystream1

HLS 推流地址：

rtmp://192.168.1.152:1935/hls/mystream2

拉流地址：

http://192.168.1.176:8008/hls/mystream2/index.m3u8 http://192.168.1.183:8008/hls/mystream2/index.m3u8

3 回调

3.1 RTMP 推流回调

rtmp {server {listen 1935;#notify_method get;application hls { live on;publish_notify on; hls on;hls_path /tmp/hls; hls_cleanup off;on_publish http://192.168.1.182:8080/publish; on_publish_done http://192.168.1.182:8080/publish_done;}}

3.1.1 on_pulish

推流开始时起效

"app" = "hls""flashver" = "FMLE/3.0 (compatible; FMSc/1.0)" "swfurl" = "rtmp://192.168.1.152:1935/hls" "tcurl" = "rtmp://192.168.1.152:1935/hls" "pageurl" = """addr" = "192.168.1.168""clientid" = "65" "call" = "publish" "name" = "11520301""type" = "live"参数：

3.1.2 on_publish_done

推流结束时起效

参数：

3.2 RTMP 拉流回调

rtmp {server {listen 1935;#notify_method get;application hls {live on;publish_notify on;#notify_method get; hls on;hls_path /tmp/hls; hls_cleanup off;on_play http://192.168.1.182:8080/play; on_play_done http://192.168.1.182:8080/play_done;}}}

3.2.1 on_play

拉流开始时起效

参数：

"app" = "hls""flashver" = "LNX 9,0,124,2" "swfurl" = """tcurl" = "rtmp://192.168.1.152:1935/hls" "pageurl" = """addr" = "192.168.1.168""clientid" = "127" "call" = "play" "name" = "myplay""start" = "4294965296""duration" = "0""reset" = "0"

3.2.2 on_play_done

拉流结束时起效

"app" = "hls""flashver" = "LNX 9,0,124,2" "swfurl" = """tcurl" = "rtmp://192.168.1.152:1935/hls" "pageurl" = """addr" = "192.168.1.168""clientid" = "127" "call" = "play_done" "name" = "myplay"参数：

3.3 录制结束回调

rtmp {server {listen 1935;#notify_method get;application live {live on;recorder myvideo { record all;record_path /tmp/hls;

record_suffix .mp4; record_notify on;on_record_done http://192.168.1.182:8080/record_done;}}}

3.3.1 on_record_done

在录制结束时起效

参数：

"app" = "live""flashver" = "FMLE/3.0 (compatible; FMSc/1.0)" "swfurl" = "rtmp://192.168.1.152:1935/live" "tcurl" = "rtmp://192.168.1.152:1935/live" "pageurl" = """addr" = "192.168.1.168""clientid" = "157" "call" = "record_done""recorder" = "myvideo""name" = "bbbbbb"

"path" = "/tmp/hls/bbbbbb.mp4""myvideo" = "bbbbbb"

根据目前业务看，主要考虑推流回调及录制结束回调，即需要业务处理推流开始、推流结束、录制结束的回调

on_publish on_publish_done on_record_done
