Nginx与Nginx-rtmp-module搭建RTMP视频直播和点播服务器

一.开发环境

　　Nginx地址:  http://nginx.org/download/nginx-1.14.2.tar.gz

　　Nginx-rtmp-module地址: https://github.com/arut/nginx-rtmp-module

二.执行安装命令

　　备份nginx原文件

cp /usr/local/openresty/nginx/sbin/nginx /usr/local/openresty/nginx/sbin/nginx.bak.201812.1.rtmp　

　　下载模块并解压: 

cd /thirdparties

wget https://github.com/arut/nginx-rtmp-module/archive/master.zip

unzip  master.zip

　　添加模块并编译openresty（注意：重新编译的时候，记得一定要把以前编译过的模块一同加到configure参数里面）

查看原来的模块

/usr/local/openresty/nginx/sbin/nginx -V 

cd /thirdparties/openresty-1.11.2.2

./configure --prefix=/usr/local/openresty  --add-module=/thirdparties/nginx-rtmp-module-master --with-http_ssl_module

make

　　停止nginx

/usr/local/openresty/nginx/sbin/nginx -s stop

　　备份nginx原文件

mv /usr/local/openresty/nginx/sbin/nginx /usr/local/openresty/nginx/sbin/nginx.bak.201812.origin.rtmp　

　　将编译后的nginx文件覆盖原文件并重启nginx

cp /thirdparties/openresty-1.11.2.2/build/nginx-1.11.2/objs/nginx /usr/local/openresty/nginx/sbin
/usr/local/openresty/nginx/sbin/nginx

查看module是否已经加入到nginx

/usr/local/openresty/nginx/sbin/nginx -V

三.nginx的配置

　　在添加完模块后nginx的配置文件（ /usr/local/nginx/conf/nginx.config）中要增加对rtmp的配置

　　与http {... ...}同级的地方配置rtmp

　　

　　events {
　　　　use epoll;
　　　　worker_connections 1024;
　　}

            hls on; #这个参数把直播服务器改造成实时回放服务器。
            wait_key on; #对视频切片进行保护，这样就不会产生马赛克了
            hls_path /opt/video/hls; #切片视频文件存放位置

}

 

 

 

注意：

　　1. 如果不存在文件夹“/opt/video”、“/opt/video/hls”则要创建一个，并且要改成可读可写的权限（chmod  777 /opt/video）

　　2. 防火墙是否通：

iptables -I INPUT -p tcp -m state --state NEW --dport 1935 -j ACCEPT #放行1935端口的 NEW状态请求
service iptables save #保存规则
service iptables restart #重启防火墙保证新的规则加载进来
