# 准备： #

操作系统：CentOS 7  
Web服务器：Nginx  
版本控制器：Git

# 搭建： #

大部分视频直播平台使用的协议都是RTMP，Nginx也有RTMP的扩展模块，所以我也选用RTMP进行服务器的搭建。

# 1.获取nginx-rtmp-module模块扩展 #

## 1.1.nginx-rtmp-module的Git地址是`https://github.com/arut/nginx-rtmp-module.git`，直接获取： ##

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

# 2.安装Nginx #

## 2.1.下载Nginx ##

wget http://nginx.org/download/nginx-1.15.7.tar.gz

## 2.2.解压 ##

tar -zxvf nginx-1.15.7.tar.gz

## 2.3.编译并安装 ##

cd nginx-1.15.7
    
    ./configure --prefix={Nginx安装路径}  --add-module={nginx-rtmp-module的路径}  --with-http_ssl_module
    
    make && make install

编译安装过程中可能会出错，一般错误都是缺少一些组件，根据报错信息使用 yum install 进行安装。

# 3.配置Nginx #

## 3.1.修改Nginx配置 ##

vim {Nginx安装路径}/conf/nginx.conf

打开Nginx配置文件，加入如下部分：

rtmp {   
        server {   
            listen 1935;  #监听的端口 
            chunk_size 4000;   #流整合的最大的块大小,这个值设置的越大 CPU 负载就越小
            #增加对hls的支持
            application hls {  #rtmp推流请求路径
                live on;   #开启实时
                hls on;   #开启hls
                hls_path /usr/share/nginx/html/hls; #推流文件保存的路径,要有写入权限
                hls_fragment 5s;   # 每个文件包含5秒的视频内容
            }   
        }   
    }

Nginx中RTMP模块配置的更多参数可以参考官方文档，到这里Nginx的配置已经完成并且加入了RTMP模块的扩展。

4.启动Nginx

{Nginx安装路径}/sbin/nginx -c {Nginx安装路径}/conf/nginx.conf

使用浏览器访问服务器，如果出现以下画面表示Nginx成功启动。

Linux命令

systemctl status firewalld		//查看防火墙状态 
    systemctl start firewalld  		//开启防火墙 
    systemctl stop firewalld		//关闭防火墙 
    service firewalld start 		//开启防火墙 
    若遇到无法开启
    先用：systemctl unmask firewalld.service 
    然后：systemctl start firewalld.service
    firewall-cmd --query-port=666/tcp        //查询666端口是否开放；提示 yes，表示开启；no表示未开启。
    firewall-cmd --add-port=666/tcp --permanent //添加指定需要开放的端口
    firewall-cmd --reload		//重载入添加的端口
    firewall-cmd --query-port=666/tcp 	//查询指定端口是否开启成功

# 4.配置nginx的service服务 #

vim /etc/init.d/nginx 将下面的代码复制进去保存

#!/bin/bash  
    # nginx Startup script for the Nginx HTTP Server  
    #  
    # chkconfig: - 85 15

    nginxlog=/var/log/nginx/activity_screen
    nginxd=/usr/local/nginx/sbin/nginx  
    nginx_config=/usr/local/nginx/conf/nginx.conf  
    nginx_pid=/usr/local/nginx/logs/nginx.pid  
    RETVAL=0  
    prog="nginx" 
    # Source function library.  
    . /etc/init.d/functions
    # Source networking configuration.  
    . /etc/sysconfig/network  
    # Check that networking is up.  
    [ ${NETWORKING} = "no" ] && exit 0  
    [ -x $nginxd ] || exit 0  
    [ -d $nginxlog ] || mkdir -p $nginxlog  
    # Start nginx daemons functions.  
    start() {  
    if [ -e $nginx_pid ];then 
       echo "nginx already running...." 
       exit 1  
    fi  
       echo -n $"Starting $prog: " 
       daemon $nginxd -c ${nginx_config}  
       RETVAL=$?  
       echo  
       [ $RETVAL = 0 ] && touch /var/lock/subsys/nginx  
       return $RETVAL  
    }  
    # Stop nginx daemons functions.  
    stop() {  
            echo -n $"Stopping $prog: " 
            killproc $nginxd  
            RETVAL=$?  
            echo  
            [ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /var/run/nginx.pid  
    }  
    # reload nginx service functions.  
    reload() {  
        echo -n $"Reloading $prog: " 
       $nginxd -s reload  
        RETVAL=$?  
        echo  
    }  
    # See how we were called.  
    case "$1" in 
    start)  
            start  
            ;;  
    stop)  
            stop  
            ;;  
    reload)  
            reload  
            ;;  
    restart)  
            stop  
            start  
            ;;  
    status)  
            status $prog  
            RETVAL=$?  
            ;;  
    *)  
            echo $"Usage: $prog {start|stop|restart|reload|status|help}" 
            exit 1  
    esac  
    exit $RETVAL

切换目录，启动服务

# 5.设置开机启动 #

sudo wget https://raw.github.com/JasonGiedymin/nginx-init-ubuntu/master/nginx -O /etc/init.d/nginx
    sudo chmod +x /etc/init.d/nginx
    sudo update-rc.d nginx defaults

# 6.启动nginx服务 #

sudo service nginx start
    sudo service nginx stop
