# 实现结果 #

推流的实现：使用OBS Studio进行推流  
拉流播放的实现：使用VLC进行拉流地址播放  
直播服务器实现：centos系统下的nginx+RTMP模块

# 实现步骤： #

## 第1步：nginx相关依赖包的安装 ##

nginx相关依赖包的安装：

yum install -y perl-ExtUtils-Embed readline-devel zlib-devel pam-devel libxml2-devel libxslt-devel openldap-devel python-devel gcc-c++   openssl-devel cmakepcre-develnanowget  gcc gcc-c++ ncurses-devel perl

其他需要用到的依赖包：

yum -y install git
    yum -y install nano
    yum -y install wget

## 第2步：nginx-rtmp-module ##

nginx-rtmp-module,[官方github地址][github]

// 通过git clone 的方式下载到服务器上
    [root~]# git clone https://github.com/arut/nginx-rtmp-module.git

## 第3步：安装Nginx服务器 ##

1.下载Nginx解压，并安装rtmp和openssl的模块  
PS:add-module=/data/bak/nginx-rtmp-module 中的/data/bak是自己的下载的相关模块的存放路径

[root~]# wget http://nginx.org/download/nginx-1.10.3.tar.gz 
    [root~]# tar -zxvf nginx-1.10.3.tar.gz 
    [root~]# cd nginx-1.10.3
    //添加rtmp和openssl支持
    [root~]# ./configure --add-module=/data/bak/nginx-rtmp-module --with-http_ssl_module
    [root~]# make && make install

## 第4步：查看安装模块信息： ##

[root@localhost nginx-1.10.3]# ln -s /usr/local/nginx/sbin/nginx /usr/bin/nginx
    [root@localhost nginx-1.10.3]# nginx -V
    nginx version: nginx/1.10.3
    built by gcc 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) 
    built with OpenSSL 1.0.2k-fips  26 Jan 2017
    TLS SNI support enabled
    configure arguments: --add-module=/data/bak/nginx-rtmp-module --with-http_ssl_module

## 第5步：启动nginx,查看启动的情况 ##

[root@localhost nginx-1.10.3]# nginx -s stop
    [root@localhost nginx-1.10.3]# nginx
    [root@localhost nginx-1.10.3]# curl http://192.168.74.128/
    <!DOCTYPE html>
    <html>
    <head>
    <title>Welcome to nginx!</title>
    <style>
        body {
            width: 35em;
            margin: 0 auto;
            font-family: Tahoma, Verdana, Arial, sans-serif;
        }
    </style>
    </head>
    <body>
    <h1>Welcome to nginx!</h1>
    <p>If you see this page, the nginx web server is successfully installed and
    working. Further configuration is required.</p>
    
    <p>For online documentation and support please refer to
    <a href="http://nginx.org/">nginx.org</a>.<br/>
    Commercial support is available at
    <a href="http://nginx.com/">nginx.com</a>.</p>
    
    <p><em>Thank you for using nginx.</em></p>
    </body>
    </html>
    [root@localhost nginx-1.10.3]#

## 第6步：配置相关的模块信息修改nginx.conf ##

PS：注意是在http\{\}外进行添加：

rtmp {
        server {
            listen 1935;
            application rtmplive {
                live on;
                record off;
            }
            application vod {
            play /opt/video/vod;
            }
    
        }
    }

完成的配置文件如下：

#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;
    }
    
    
    http {
        include       mime.types;
        default_type  application/octet-stream;
    
        #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
        #                  '$status $body_bytes_sent "$http_referer" '
        #                  '"$http_user_agent" "$http_x_forwarded_for"';
    
        #access_log  logs/access.log  main;
    
        sendfile        on;
        #tcp_nopush     on;
    
        #keepalive_timeout  0;
        keepalive_timeout  65;
    
        #gzip  on;
    
        server {
            listen       1980;
            server_name  localhost;
    
            #charset koi8-r;
    
            #access_log  logs/host.access.log  main;
    
            location /stat {
                rtmp_stat all;
                rtmp_stat_stylesheet stat.xsl;
            }
    
            location /stat.xsl {
               root /home/developer/zhoucl/obs/nginx-rtmp-module/;
            }
    
    
            location / {
                root   html;
                index  index.html index.htm;
            }
    
            #error_page  404              /404.html;
    
            # redirect server error pages to the static page /50x.html
            #
            error_page   500 502 503 504  /50x.html;
            location = /50x.html {
                root   html;
            }
    
            # proxy the PHP scripts to Apache listening on 127.0.0.1:80
            #
            #location ~ \.php$ {
            #    proxy_pass   http://127.0.0.1;
            #}
    
            # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
            #
            #location ~ \.php$ {
            #    root           html;
            #    fastcgi_pass   127.0.0.1:9000;
            #    fastcgi_index  index.php;
            #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
            #    include        fastcgi_params;
            #}
    
            # deny access to .htaccess files, if Apache's document root
            # concurs with nginx's one
            #
            #location ~ /\.ht {
            #    deny  all;
            #}
        }
    
    
        # another virtual host using mix of IP-, name-, and port-based configuration
        #
        #server {
        #    listen       8000;
        #    listen       somename:8080;
        #    server_name  somename  alias  another.alias;
    
        #    location / {
        #        root   html;
        #        index  index.html index.htm;
        #    }
        #}
    
    
        # HTTPS server
        #
        #server {
        #    listen       443 ssl;
        #    server_name  localhost;
    
        #    ssl_certificate      cert.pem;
        #    ssl_certificate_key  cert.key;
    
        #    ssl_session_cache    shared:SSL:1m;
        #    ssl_session_timeout  5m;
    
        #    ssl_ciphers  HIGH:!aNULL:!MD5;
        #    ssl_prefer_server_ciphers  on;
    
        #    location / {
        #        root   html;
        #        index  index.html index.htm;
        #    }
        #}
    
    }
    rtmp {
        server {
            listen 1935;
            application rtmplive {
                live on;
                record off;
                hls on;
                hls_path /usr/local/nginx/data/hls;
    
             }
            application video {
            play /opt/video;
            }
        }
    }

## 第7步：关闭防火墙，为方便测试 ##

ps:一般线上环境是不会直接关闭防火墙，而是开放对应的端口。写对应的规则！

systemctl stop firewalld

## 第8步：重启的启动nginx,并用浏览器打开：[http://192.168.74.128/stat][http_192.168.74.128_stat] ##

[root@localhost nginx-1.10.3]# nginx -s reload
    [root@localhost nginx-1.10.3]# curl http://192.168.74.128/stat
    <?xml version="1.0" encoding="utf-8" ?>
    <?xml-stylesheet type="text/xsl" href="stat.xsl" ?>
    <rtmp>
    <nginx_version>1.10.3</nginx_version>
    <nginx_rtmp_version>1.1.4</nginx_rtmp_version>
    <compiler>gcc 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) </compiler>
    <built>Feb 26 2018 21:48:59</built>
    <pid>29574</pid>
    <uptime>608</uptime>
    <naccepted>0</naccepted>
    <bw_in>0</bw_in>
    <bytes_in>0</bytes_in>
    <bw_out>0</bw_out>
    <bytes_out>0</bytes_out>
    <server>
    <application>
    <name>rtmplive</name>
    <live>
    <nclients>0</nclients>
    </live>
    </application>
    <application>
    <name>vod</name>
    <play>
    <nclients>0</nclients>
    </play>
    </application>
    </server>
    </rtmp>

PS：说明启动成功

<name>rtmplive</name>
    <live>
    <nclients>0</nclients>
    </live>
    </application>
    <application>
    <name>vod</name>

## 第9步：使用OBS Studio进行推流 ##

首先在PC端安装一下OBS Studio ：[https://obsproject.com/download\#mp][https_obsproject.com_download_mp]  
启动后的软件示意图：
