Nginx+RTMP
直播服務器集群1 直播服務器搭建
1.1 系統環境
操作系統：Centos7.3
系統版本：CentOS Linux release 7.3.1611 (Core)
Nginx 版本：1.12
1.2 RTMP 模塊安裝
Git clone
添加到 Nginx 模塊中編譯 --add-module
例如：
上圖表明系統 Nginx 已經加載了 RTMP 模塊
注意，如果需要支持 H.264，需額外安裝 nginx_mod_h264_streaming 模塊
wget
需 要 注 釋 掉 nginx_mod_h264_streaming-
2.2.7/src/ngx_http_streaming_module.c 的以下內容：
if (r->zero_in_uri)
{
return NGX_DECLINED;
}
如上圖表明已經加載 h264 模塊
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;
}
}
參數簡要說明：
record
錄製相關
語法: record [off|all|audio|video|keyframes|manual]*
· off - 不記錄在所有
· all - 音頻和視頻（一切）
· audio -音頻
· video - 視頻
· keyframes -唯一的關鍵幀視頻
· manual - 從來沒有自動啟動記錄儀，使用控制界面來啟動/停止
record_path
指定錄製文件的路徑
record_suffix
錄製文件的格式
語法: record_suffix value
該參數默認為 Flv 格式，即不定義的話錄製文件格式為.Flv
record_suffix %Y%m%d%H%M%S.mp4 表示錄製文件為 mp4 格式
record_unique
是否打開追加當前的時間戳，默認為 off
record_append
切換文件追加模式以上
application appname {
……
}
配置完成後，重啟 nginx，即可進行推拉流測試
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;
}
}
參數說明：
hls on; 表示打開回看（HLS）
hls_path; hls 文件路徑，即.m3u8 以及 ts 切片文件路徑
完成以上 rtmp{……} 及 http {……} 配置後，即可進行推拉流例如：
推流地址： rtmp://localhost:1935/hls/mystream1
拉流地址： rtmp://localhost:8008/hls/mystream1/index.m3u8
2 直播服務器轉推集群
2.1 集群配置
Nginx+RTMP 可以實現直播、點播，但單機性能有限，就需要集群。本方案採用
RTMP 推流服務器公用，輔助多節點代理服務器，用戶通過節點拉流請求代理轉發到推流服務器。
配置示例如下：
推流服務器 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;
}
}
}
拉流服務器（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
對應拉流地址：
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
對應拉流地址：
http://192.168.1.152:8008/hlslive/stream2/index.m3u8 （本地拉流）
:8080/hlslive/stream2/index.m3u8 （代理節點拉流）
2.2 集群測試
在推流服務器上使用 OBS 推流，然後在拉流服務器上通過 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

3.3 錄製結束回調
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
在錄製結束時起效
參數：
"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"
根據目前業務看，主要考慮推流回調及錄製結束回調，即需要業務處理推流開始、推流結束、錄製結束的回調
on_publish on_publish_done on_record_done
