搭建基于Http点播的nginx服务器

20 Apr 2019

* 安装环境：CentOS 6.10

1. 安装依赖库

   yum install automake autoconf make gcc gcc-c++
   yum install pcre pcre-devel
   yum install zlib zlib-devel
   yum install openssl openssl-devel
   

2. 获取nginx源码并编译

   wget http://nginx.org/download/nginx-1.14.2.tar.gz
   tar xvf nginx-1.14.2.tar.gz
   # 主要是with-http_mp4_module模块用于支持http的mp4视频直播
   # with-http_auth_request_module 这个模块用于授权，从远程连接获取授权信息做访问控制
   ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-http_flv_module --with-http_mp4_module --with-http_auth_request_module
   make
   make install
   

3. 安装可执行文件到系统

   # 删除原nginx, 创建软连接
   cd /usr/sbin
   ln -s /usr/local/nginx/sbin/nginx nginx 
   

4. 配置nginx，具体信息见nginx配置

   cd /usr/local/nginx/conf
   vim nginx.conf
   
   # 替换nginx文件配置为nginx.conf
   

5. 启动和停止

   nginx
   # 停止
   kill -9 `ps aux|grep nginx| awk '{print $2}'`
   

6. nginx配置详细

   worker_processes 8;
   
   events {
       worker_connections  1024;
   }
   
   http {
       include       mime.types;
       default_type  application/octet-stream;
       access_log off;
       sendfile_max_chunk 512k;
       sendfile        on;
       tcp_nopush     on;
       keepalive_timeout  65;
       gzip  on;
   
       server {
   
           listen      80;
           server_name _;
   
       location = /auth {
           # 授权请求配置
           internal;
           proxy_pass http://api.test.com/api/auth/;
           proxy_pass_request_body off;
           proxy_set_header        Content-Length "";
           proxy_set_header        X-Original-URI $request_uri;
       }
       location ~ \.mp4$
       {
        # 通知auth获取授权信息，返回200授权成功，否则失败
        auth_request /auth;
        # auth_request_set $auth_status $upstream_status;
        root /data/videos;
        mp4;
        mp4_buffer_size    10m;
        mp4_max_buffer_size  50m;
        # limit_rate_after 40m;
        # limit_rate 10000k;
        #    limit_conn perip 1;
       }
       }
   }
