Linux搭建流服务器笔记-优快云博客

一、环境安装

CentOS

1、安装wget，yum install -y wget;

2、安装基础环境，yum -y install gcc gcc-c++ autoconf automake make；

3、下载安装nginx，wget http://nginx.org/download/nginx-1.15.0.tar.gz；

4、解压nginx，tar -zxvf nginx-1.15.0.tar.gz；

5、移动解压目录到 /usr/local/，mv nginx-1.15.0 /usr/local/；

6、使用git下载nginx-rtmp-module，git clone https://github.com/arut/nginx-rtmp-module.git（如果没有安装git使用yum进行安装，yum install git）

7、编译和安装（如果出现PCRE错误，执行yum -y install pcre-devel openssl openssl-devel）；

cd /usr/local/nginx-1.15.0
./configure
make
make install

8、从/usr/local/nginx（默认路径）目录执行nginx，/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf；

9、打开浏览器，输入localhost:80尝试访问；

Ubuntu

1、新建一个目录/etc/rtmpServer（下载路径），mkdir -P /etc/rtmpServer；

2、安装基础环境，apt-get update，apt-get install libpcre3 libpcre3-dev，apt-get install openssl libssl-dev；

4、安装nginx，wget http://nginx.org/download/nginx-1.8.1.tar.gz；

5、解压，tar -zxvf nginx-1.8.1.tar.gz；

6、使用git下载nginx-rtmp-module，git clone https://github.com/arut/nginx-rtmp-module.git

7、配置并编译nginx，cd nginx-1.8.1，./configure --add-module=../nginx-rtmp-module，make，sudo make install；

8、进入/usr/local/nginx，运行命令./sbin/nginx（重载为./sbin/nginx -s reload）；

9、打开浏览器，输入localhost:80尝试访问；

二、点播服务器配置（CentOS与Ubuntu同）

worker_processes 1;
events {
worker_connections 1024;
}
rtmp { #RTMP服务
server {
listen 1935; #//服务端口
chunk_size 4096; #//数据传输块的大小

application vod {
play /opt/video/vod; #//视频文件存放位置。
}
}
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name localhost;
location / {
root html;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}

三、直播服务器配置

worker_processes 1;

events {
worker_connections 1024;
}

rtmp {
server {
listen 1935;
chunk_size 4096;

application vod {
play /opt/video/vod;
}

application live{ #第一处添加的直播字段
live on;
}
}

}

http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name localhost;

location /stat { #第二处添加的location字段。
rtmp_stat all;
rtmp_stat_stylesheet stat.xsl;
}

location /stat.xsl { #第二处添加的location字段。
root /etc/rtmpServer/nginx-rtmp-module/;
}

location / {
root html;
index index.html index.htm;
}

error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}

四、实时回看视频服务器配置

可以在对应目录下看到ts文件和m3u8文件即为视频片段及目录，用拉流软件拉取即可，地址类似：http://localhost/live/rtmp/index.m3u8。如果用h5观看，html文件需放在nginx容器中，且src需要填写服务器的ip地址，不能填写localhost。

参考h5代码如下：

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
<link href="http://vjs.zencdn.net/5.19/video-js.min.css" rel="stylesheet">
<script src="http://vjs.zencdn.net/5.19/video.min.js"></script>
</head>
<body>
<video
id="my-player"
class="video-js"
controls
preload="auto"
poster="//vjs.zencdn.net/v/oceans.png"
data-setup='{}'>
<source src='rtmp://你的服务器IP/live/rtmp' type='rtmp/flv'/> （关注此行！！！）
</p>
</video>
<script type="text/javascript">
var player = videojs('my-player');
var options = {};

var player = videojs('my-player', options, function onPlayerReady() {
videojs.log('Your player is ready!');
// In this context, `this` is the player that was created by Video.js.
this.play();
// How about an event listener?
this.on('ended', function() {
videojs.log('Awww...over so soon?!');
});
});

</script>
</body>
</html>

五、注意点

1、添加完成后需要重新启动nginx，由于这次nginx需要向服务器写切片视频文件，但nginx我又没有给nginx指定用户名只能走默认的nobody用户和nogroup用户组，其实就是没有组。所以我对需要写入的目录做了增大权限的修改。

2、默认形成RTMP的live流，可以通过推流软件修改流的名字，比如OBS里的输出设置。

3、Ubuntu安装拉流软件vlc时，可通过snap install vlc完成。

4、CentOS如果已经装了Apache的，需要通过systemctl stop httpd，systemctl start nginx命令（Ubuntu类似）。

5、注意防火墙是否关闭，CentOS的firewalld（systemctl diable firewalld），Ubuntu的ufw（ufw diable）。

6、下载推流软件，Ubuntu可以通过更新安装源下载，

sudo add-apt-repository ppa:obsproject/obs-studio //添加源
sudo apt-get update //更新源
sudo apt install obs-studio //安装

7、记得安装ffmpeg。
