Centos中安装带rtmp模块的Nginx

很多流媒体功能如直播，点播等功能都能够通过Nginx实现。

Nginx官方有一个hls模块实现了HlS协议，但是这个模块为企业版Nginx功能，github上有大佬自己编写了一个开源的nginx-rtmp-module，实现了Nginx官方的hls协议

在Linux系统中安装Nginx时，即可通过二进制编译添加该模块，后续即可以实现rtmp协议。

通过github上的readme指导安装，以下是安装过程，以及一些安装中碰到的小问题

一、Centos安装

参考网上Centos安装教程，默认安装就行了，因为只是作为推流服务器和流媒体服务器使用，所以安装的是最小版本。

二、环境准备

1.编译工具安装

安装好CentOS以后，需要安装各种编译工具，如pcre，gcc等，用于对二进制源码进行编译安装

具体命令如下

yum install -y pcre pcre-devel openssl openssl-devel zlib zlib-devel gcc gcc-c++ 

安装一些支持工具

如vim，wget和lsof

yum install -y vim wget lsof git zip unzip

###2. 获取Nginx二进制源码

通过测试，rtmp模块暂时只支持Nginx13-15版本，在官网中下载稳定版的Nginx14

wget http://nginx.org/download/nginx-1.14.2.tar.gz

下载nginx-rtmp-module

wget https://github.com/arut/nginx-rtmp-module/archive/refs/tags/v1.2.1.tar.gz

下载源码以后，解压

tar xf v1.2.1.tar.gz
tar xf nginx-1.14.2.tar.gz

配置编译，将rtmp模块添加到nginx中

如果出现./configure: error: no ../nginx-rtmp-module/config was found

去掉--with-http_ssl_module重新配置一次，或者直接重新配置

配置完成后直接进行编译安装

cd nginx-1.14.2
./configure --add-module=../nginx-rtmp-module-1.2.1/ --with-http_ssl_module
make && make install
#建立软链接
ln -s /usr/local/nginx/sbin/nginx /usr/bin

三、安装后配置

1. 启用rtmp配置

#user  nobody;
worker_processes  1;

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

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}

        server {
                listen 1935;

                application live {
                        live on;
                }

                application hls {
                        live on;
                        hls on;
                        hls_path /usr/local/nginx/hls;
                        hls_fragment 8s;
                }
        }
}

        }

    }

}

2. 开启Nginx服务

nginx

3. 开启端口

firewall-cmd --zone=public --add-port=80/tcp --permanent
firewall-cmd --zone=public --add-port=1935/tcp --permanent

4.验证服务

通过OBS等测试是否成功
