nginx rtmp/hls for CentOS

---

虚拟机设置为桥接模式，与本机地址同网段

安装git

yum -y install git

下载nginx-rtmp-module

git clone https://github.com/arut/nginx-rtmp-module.git

安装openssl

yum -y install openssl openssl-devel

下载nginx-1.10.3.tar.gz

wget http://nginx.org/download/nginx-1.10.3.tar.gz

解压nginx-1.10.3.tar.gz

tar -zxvf nginx-1.10.3.tar.gz

添加rtmp和openssl支持

cd nginx-1.10.3
./configure --add-module=/root/nginx-rtmp-module --with-http_ssl_module

编译安装

make && make install

启动nginx

/usr/local/nginx/sbin/nginx

如出现错误

nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
nginx: [emerg] still could not bind()

表示80端口被占用，需要查看端口PID，然后根据PID将相关进程关闭后重启

lsof -i tcp:80
kill PID
/usr/local/nginx/sbin/nginx

修改nginx配置文件nginx.conf，rtmp配置

vi /usr/local/nginx/conf/nginx.conf

按i进入编辑模式，在最后的空白处，添加以下：

rtmp {  
    server {  
        listen 1935;  
        chunk_size 4000;  
        application hls { 
            live on;
            hls on;
            hls_path /home/hls/test;
            hls_fragment 3s;
        }  
    }  
}

rtmp是协议名称
server 说明内部中是服务器相关配置
listen 监听的端口号, rtmp协议的默认端口号是1935
application 访问的应用路径是 hls
live on; 开启实时
record off; 不记录数据

hls配置，http的server下添加以下：

server {
    listen      80;
    location /hls {    
           #server hls fragments    
           types{    
             application/vnd.apple.mpegurl m3u8;    
             video/mp2t ts;    
           }    
        alias /home/hls/test;    
        expires -1;    
        } 

按esc 输入:wq 回车保存，重启nginx

[root~]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

进入/home目录并创建 hls及其子目录test

cd /home
mkdir hls
cd hls
mkdir test

服务器开放1935端口或关闭防火墙

//CentOS7 默认使用firewalld防火墙
//关闭firewall
systemctl stop firewalld.service
//禁止firewall开机启动
systemctl disable firewalld.service
//查看防火墙状态(关闭后显示not running，开启后显示 running)
firewall-cmd --state
 
 
//iptables开放端口
/sbin/iptables -I INPUT -p tcp --dport 1935 -j ACCEPT
//保存配置
/etc/rc.d/init.d/iptables save
//重启服务
/etc/rc.d/init.d/iptables restart
//查看端口开放状态
/etc/init.d/iptables status

打开浏览器，输入ip地址，显示如下表明搭建成功：

使用OBS推流rtmp

使用vlc拉流

ipc推流

使用OBS推流hls

使用safari拉流hls(http://172.18.30.231/hls/test.m3u8)

此时服务器上的/home/hls/test/目录下会生成一个m3u8文件以及多个ts文件

至此，模拟结束。
