利用Nginx搭建自己的rtmp服务器

前几天的文章大疆机场开发五（直播功能和遇到的问题）中讲到，机场直播支持rtmp直播，如果我没有rtmp地址怎么办？这篇文章讲一下如何部署一个自己的rtmp服务器，nginx资源已上传，已配置好，可直接运用。

一、下载Nginx及响应模块

首先，去官方下载Nginx，还需要下载nginx-rtmp-module模块，将模块复制到Nginx的文件夹下面如图。

二、修改config文件

修改conf文件夹下面的conf文件，可复制里面的nginx.conf重命名，也可直接修改。

#user  nobody;
# multiple workers works !
worker_processes  2;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

events {
    worker_connections  8192;
    # max value 32768, nginx recycling connections+registry optimization = 
    #   this.value * 20 = max concurrent connections currently tested with one worker
    #   C1000K should be possible depending there is enough ram/cpu power
    # multi_accept on;
}

rtmp {
    server {
        listen 1935;#监听端口,若被占用,可以更改
        chunk_size 4000;#上传flv文件块儿的大小
        application live { #创建一个叫live的应用
             live on;#开启live的应用
             allow publish 192.168.2.77;#
             allow play all;
        }
    }
}

}

接着双击 nginx.exe即可。如果没有报错即代表nginx运行成功，自己本地的rtmp默认地址为rtmp://ip:1935/live。
