使用nginx搭建点播和直播流媒体服务器的方法步骤

环境   centos7 nginx

1 安装nginx依赖包 yum install gcc gcc-c++ openssl-devel zlib-devel pcre pcre-devel yamdi

2.下载解压nginx_mod_h264_streaming,让nginx支持flv,mp4流播放   wget http://h264.code-shop.com/download/nginx_mod_h264_streaming-2.2.7.tar.gz 解压后需要修改src目录下的ngx_http
_streaming_module.c文件,将r->zero_in_uri所在的if语句注释掉

3.下载解压nginx-rtmp-module,让nginx支持rtmp/hls协议，wegt -o nginx-rtmp-module.zip  https://github.com/arut/nginx-rtmp-module/archive/master.zip

4下载清除缓存的模块 wget -Ongx_cache_purge.zip     https://github.com/FRiCKLE/ngx_cache_purge/archive/master.zip

5.下载nginx  wget http://nginx.org/download/nginx-1.9.0.tar.gz

6 .进入nginx的安装目录下 执行以下命令./configure --prefix=/usr/local/nginx/--add-module=../nginx-rtmp-module-master --add-module=../ngx_cache_purge-master--add-module=../nginx_mod_h264_streaming-2.2.7 --with-http_stub_status_module--with-http_ssl_module --with-http_sub_module --with-http_gzip_static_module--with-http_flv_module

7. 执行以下命令编译文件make && make install ，并修改nginx安装目录下的objs下的Makefile 删除-Werror

9. 修改nginx.conf

10. 通过yum 停止firewalld防火墙并卸载，然后安装iptables-services修改/etc/sysconfig/iptables文件夹放行80端口

11.nginx 配置如下：

#使用的用户和组
#user nobody;
#指定工作衍生的进程数，为cpu的核心数总和
worker_processes 2;
#指定错误日志的存放路径 日志记录级别[debug,info,notice,warn,error,crit]
error_log  /usr/local/nginx/logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#指定pid存放的路径
pid    /usr/local/nginx/logs/nginx.pid;
events {
  #使用的网络I/O模型，linux系统推荐是epoll而freeBSD是kqueue
  use epoll;
  #允许的连接数，最大的高并发连接数为worker_processes*worker_connections
  worker_connections 51200;
}

12. 输入xxx.xxx.xxx.xxx/*.mp4/*.flv就能播放视频了
