1. 下载扩展包

$ cd /soft
$ wget https://github.com/arut/nginx-rtmp-module/archive/v1.1.10.tar.gz 
//解压扩展包
$ tar -zxvf v1.1.10.tar.gz
#为nginx创建扩展模块目录
$ mkdir /usr/local/nginx/extend_module
#将解压后的nginx-rtmp-module目录移动到nginx扩展模块目录下
$ mv nginx-rtmp-module-1.1.10/ /usr/local/nginx/extend_module/nginx-rtmp-module

2. 查看nginx配置参数

$ /usr/local/nginx/sbin/nginx -V
#复制configure arguments：后的所有参数! 如下：
nginx version: nginx/1.13.10
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-23) (GCC) 
built with OpenSSL 1.0.1e-fips 11 Feb 2013
TLS SNI support enabled
configure arguments: --prefix=/usr/local/nginx --sbin-path=/usr/local/nginx/sbin/nginx --conf-path=/usr/local/nginx/conf/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx/nginx.pid --lock-path=/var/lock/nginx.lock --user=nginx --group=nginx --with-http_ssl_module --with-http_stub_status_module --with-http_gzip_static_module --http-client-body-temp-path=/var/tmp/nginx/client/ --http-proxy-temp-path=/var/tmp/nginx/proxy/ --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi --http-scgi-temp-path=/var/tmp/nginx/scgi --with-pcre 
#进入nginx 安装包目录，添加模块
$cd /soft/nginx-1.13.10
#复制刚才的nginx configure参数  --add-module=rtmp扩展包目录如下：
./configure --prefix=/usr/local/nginx --sbin-path=/usr/local/nginx/sbin/nginx --conf-path=/usr/local/nginx/conf/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx/nginx.pid --lock-path=/var/lock/nginx.lock --user=nginx --group=nginx --with-http_ssl_module --with-http_stub_status_module --with-http_gzip_static_module --http-client-body-temp-path=/var/tmp/nginx/client/ --http-proxy-temp-path=/var/tmp/nginx/proxy/ --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi --http-scgi-temp-path=/var/tmp/nginx/scgi --with-pcre --add-module=/usr/local/nginx/extend_module/nginx-rtmp-module
make && make install 
#重启
$ /usr/local/nginx/sbin/nginx -s reload
#再次查看是否已加载, 出现nginx-rtmp-module表示成功
$ /usr/local/nginx/sbin/nginx -V

3. 配置rtmp（防火墙需要开放1935端口）

$ vim /usr/local/nginx/conf/nginx.conf 
#在尾部添加
rtmp {
    server {
        listen 1935;  #监听的端口
        chunk_size 4000;

        application hls {  #rtmp推流请求路径
            hls on; #开启on ,关闭off
            hls_path /data/video/hls/test; #视频流m3u8文件夹
            hls_fragment 3s; #每个块的时长3秒，默认5秒
            live on; #开启实时
            record off; #不记录数据
        }
    }
}

4. 配置nginx 服务器

$ vim /usr/local/nginx/conf/vhosts/test.conf
#加入hls支持
location /hls {
    types {
        application/vnd.apple.mpegurl m3u8;
        #或 application/x-mpegURL
        video/mp2t ts;
    }
    alias /data/video/hls/test/;  #视频流文件目录(自己创建)
    expires -1;
    add_header Cache-Control no-cache;
}
#重启nginx
$ /usr/local/nginx/sbin/nginx -s reload

5. FFmepg推流

#安装ffmepg
$ yum install ffmpeg
#1. 基于mp4视频文件推流,  -acodec copy 表示默认声音编码
$ ffmpeg -re -i /data/video/hls/tt.mp4 -vcodec copy -acodec  copy -f flv rtmp://192.168.50.87:1935/hls/test

#2. 用可用rtmp直播源推流，可用直播源:
rtmp://live.hkstv.hk.lxdns.com/live/hks2
rtmp://live.hkstv.hk.lxdns.com/live/hks2
rtmp://live.hkstv.hk.lxdns.com/live/hks2

$ ffmpeg -re -i rtmp://live.hkstv.hk.lxdns.com/live/hks1 -vcodec copy -acodec copy -f flv rtmp://192.168.50.87:1935/hls/test
