云主机搭建Nginx + RTMP服务器

首先 分享一个我搭建好的直播地址:

rtmp://115.28.135.68:1935/yuzhouheike/room

复制代码

其中room这个你能够随意修改(你能够改成rtmp://115.28.135.68:1935/yuzhouheike/hades)

提早申明 直播推流的方式有不少.网上也能搜出很多教程.

其中简书上的 mac下搭建直播服务器 的教程有我看到以下两个

• Monkey_ALin 的快速集成iOS基于RTMP的视频推流,
• 嗷大喵 的OSX安装nginx和rtmp模块（rtmp直播服务器搭建） 由于云主机提供商通常只提供Linux或者Windows操做系统!因此要是你想作一个能够远程直播的服务器!只好放弃mac

此次我选择的是阿里云主机(绝对不是打广告)

• 个人云主机装操做系统的是CentOS 6.5 64位
• 受到上面两位的启发,我总结了一下要搭建一个nginx+rtmp直播推流服务器其实就两个步骤
  • 安装nginx点进去后你会发现不少版本,随便选一个就能够了,我选择的是[1.8.1]

• 增长对rtmp的支持，下载nginx-rtmp-module这个是个开源项目。 下面是项目提供的nginx配置文件样例(值得注意的就是)

这个名字决定了你的直播推流服务器的路径 (按照图中这样设置你的地址将是 rtmp://你的公网ip:1935/mytv/随便起个名)

rtmp {

    server {

        listen 1935;

        chunk_size 4000;

        # TV mode: one publisher, many subscribers
        application mytv {

            # enable live streaming
            live on;

            # record first 1K of stream
            record all;
            record_path /tmp/av;
            record_max_size 1K;

            # append current timestamp to each flv
            record_unique on;

            # publish only from localhost
            allow publish 127.0.0.1;
            deny publish all;

            #allow play all;
        }

        # Transcoding (ffmpeg needed)
        application big {
            live on;

            # On every pusblished stream run this command (ffmpeg)
            # with substitutions: $app/${app}, $name/${name} for application & stream name.
            #
            # This ffmpeg call receives stream from this application &
            # reduces the resolution down to 32x32. The stream is the published to
            # 'small' application (see below) under the same name.
            #
            # ffmpeg can do anything with the stream like video/audio
            # transcoding, resizing, altering container/codec params etc
            #
            # Multiple exec lines can be specified.

            exec ffmpeg -re -i rtmp://localhost:1935/$app/$name -vcodec flv -acodec copy -s 32x32
                        -f flv rtmp://localhost:1935/small/${name};
        }

        application small {
            live on;
            # Video with reduced resolution comes here from ffmpeg
        }

        application webcam {
            live on;

            # Stream from local webcam
            exec_static ffmpeg -f video4linux2 -i /dev/video0 -c:v libx264 -an
                               -f flv rtmp://localhost:1935/webcam/mystream;
        }

        application mypush {
            live on;

            # Every stream published here
            # is automatically pushed to
            # these two machines
            push rtmp1.example.com;
            push rtmp2.example.com:1934;
        }

        application mypull {
            live on;

            # Pull all streams from remote machine
            # and play locally
            pull rtmp://rtmp3.example.com pageUrl=www.example.com/index.html;
        }

        application mystaticpull {
            live on;

            # Static pull is started at nginx start
            pull rtmp://rtmp4.example.com pageUrl=www.example.com/index.html name=mystream static;
        }

        # video on demand
        application vod {
            play /var/flvs;
        }

        application vod2 {
            play /var/mp4s;
        }

        # Many publishers, many subscribers

        application videochat {

            live on;

            on_publish http://localhost:8080/publish;

            # Same with playing

            on_done http://localhost:8080/done;

            # All above mentioned notifications receive

            # play/publish ones. If any arguments are sent
            # with GET-style syntax to play & publish
            # these are also included.
            # Example URL:

            # record 10 video keyframes (no audio) every 2 minutes
            record keyframes;
            record_path /tmp/vc;
            record_max_frames 10;

        }


        # HLS

        # For HLS to work please create a directory in tmpfs (/tmp/hls here)
        # for the fragments. The directory contents is served via HTTP (see
        # http{} section in config)
        #
        # Incoming stream must be in H264/AAC. For iPhones use baseline H264
        # profile (see ffmpeg example).
        # This example creates RTMP stream from movie ready for HLS:
        #
        # ffmpeg -loglevel verbose -re -i movie.avi -vcodec libx264
        # -vprofile baseline -acodec libmp3lame -ar 44100 -ac 1
        # -f flv rtmp://localhost:1935/hls/movie
        #
        # If you need to transcode live stream use 'exec' feature.
        #
        application hls {
            live on;
            hls on;
            hls_path /tmp/hls;
        }

        # MPEG-DASH is similar to HLS

        application dash {
            live on;
            dash on;
            dash_path /tmp/dash;
        }
    }
}

# HTTP can be used for accessing RTMP stats
http {

    server {

        listen      8080;

        # This URL provides RTMP statistics in XML
        location /stat {
            rtmp_stat all;

            # Use this stylesheet to view XML as web page
            # in browser
            rtmp_stat_stylesheet stat.xsl;
        }

        location /stat.xsl {
            # XML stylesheet to view RTMP stats.
            # Copy stat.xsl wherever you want
            # and put the full directory path here
            root /path/to/stat.xsl/;
        }

        location /hls {
            # Serve HLS fragments
            types {
                application/vnd.apple.mpegurl m3u8;
                video/mp2t ts;
            }
            root /tmp;
            add_header Cache-Control no-cache;
        }

        location /dash {
            # Serve DASH fragments
            root /tmp;
            add_header Cache-Control no-cache;
        }
    }
}

下面开始详细步骤

• 下载nginx

# wget http://nginx.org/download/nginx-1.8.1.tar.gz
复制代码

• 下载nginx-rtmp-module

# wget https://codeload.github.com/arut/nginx-rtmp-module/zip/master
复制代码

• 切到你的nginx-1.8.1 下执行以下命令

# ./configure --prefix=/usr/local/nginx --add-module=(你的nginx-rtmp-module的绝对路径(绝对路径能够切换到那个文件下 执行命令 ```# pwd)) --with-http_ssl_module
复制代码

• 上述命令完成以后执行

# make
复制代码

• make完成以后执行

#make install
复制代码

配置nginx文件(配置样式在上面提供了,即nginx-rtmp-module githubreadme页面)

vim  /usr/local/nginx/conf/nginx.conf 
复制代码

配置完以后开启nginx

# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
复制代码

作到这里,你就能够正常使用你的直播推流服务器了!使用方法我就不赘述了
