Linux nginx+rtmp服务器配置

nginx服务器

nginx服务器是开源的高性能的http服务器，反向代理服务器，是俄罗斯的大佬开发的，在国内许多公司应用比较多，具体看百科！

反向代理服务器：代理服务器接收internet请求，然后改代理服务器将请求转向内部的服务器，内部服务器将处理的结果返回代理服务器，这个代理服务器就为反向代理服务器！

rtmp

实时消息传输协议（real time messaging protocol），主要应用在流媒体传输，实时音视频通信的协议！

nginx服务器与rtmp mudle

nginx服务器支持许多功能模块，比如http–mudle,rtmp–mudle等等，不同的mudle占用不同的端口，通过端口，客户端就可以与nginx的mudle进行通信！我们对音视频通过rtmp协议进行推流到nginx服务器，所以需要安装nginx支持的rtmp–mudle！

安装配置

开始我是在redhat版本上进行安装的,遇到的许多问题:
    红帽redhat没有apt-get命令(ubantu),使用yum一直提示没有可用的资源,就安装不了编译依赖工具
    去github下载脚本的时候,不知道什么原因也一直down不下来!
于是去下载apt-get,瞎搞了半天,没有成功,就这样前前后后折腾了几天,实在不想折腾了,就去阿里云买了一个低配置的云主机,一个月45左右,接下来环境配置一路畅通!

1.下载nginx,rtmp支持的编译依赖工具

    sudo apt-get install build-essential libpcre3 libpcre3-dev libssl-dev

2.下载nginx,以及rtmp源码,然后解压

wget http://nginx.org/download/nginx-1.8.1.tar.gz
wget https://github.com/arut/nginx-rtmp-module/archive/master.zip

3.进行解压后的ningx目录,执行configue文件

添加http,rmpt模块
./configure --with-http_ssl_module --add-module=../nginx-
rtmp-module-master

进行一些文件检测
checking for OS

checking for gcc builtin atomic operations ... found
checking for C99 variadic macros ... found

产生MakeFile文件
creating objs/Makefile

nginx安装目录:/usr/local/nginx
  nginx path prefix: "/usr/local/nginx"
  nginx binary file: "/usr/local/nginx/sbin/nginx"
  nginx configuration prefix: "/usr/local/nginx/conf"

  nginx http proxy temporary files: "proxy_temp"
  nginx http fastcgi temporary files: "fastcgi_temp"
  nginx http uwsgi temporary files: "uwsgi_temp"
  nginx http scgi temporary files: "scgi_temp"

4.编译MakeFile:make

make


产生一些临时文件
make[1]: Entering directory `/usr/stay/nginx-1.8.1'
src/core/nginx.c
cc -c -pipe  -O -W -Wall -Wpointer-arith -Wno-unused-parameter -Werror -g  -I../nginx-rtmp-module-master -I s
rc/core -I src/event -I src/event/modules -I src/os/unix -I objs \      -o objs/src/core/ngx_log.o \
        src/core/ngx_log.c
................

c -o objs/nginx \
    objs/src/core/nginx.o \
    objs/src/core/ngx_log.o \
    objs/src/event/ngx_event_posted.o \
    objs/src/event/ngx_event_accept.o 


    ake[1]: Leaving directory `/usr/stay/nginx-1.8.1'
make -f objs/Makefile manpage
make[1]: Entering directory `/usr/stay/nginx-1.8.1'
sed -e "s|%%PREFIX%%|/usr/local/nginx|" \
        -e "s|%%PID_PATH%%|/usr/local/nginx/logs/nginx.pid|" \
        -e "s|%%CONF_PATH%%|/usr/local/nginx/conf/nginx.conf|" \
        -e "s|%%ERROR_LOG_PATH%%|/usr/local/nginx/logs/error.log|" \
        < man/nginx.8 > objs/nginx.8
make[1]: Leaving directory `/usr/stay/nginx-1.8.1'

5.编译完成之后，进行安装：make install

make install

进行文件的拷贝，到/usr/local/nginx
make[1]: Entering directory `/usr/stay/nginx-1.8.1'
test -d '/usr/local/nginx' || mkdir -p '/usr/local/nginx'
test -d '/usr/local/nginx/sbin'         || mkdir -p '/usr/local/nginx/sbin'
test ! -f '/usr/local/nginx/sbin/nginx'         || mv '/usr/local/nginx/sbin/nginx'             '
/usr/local/nginx/sbin/nginx.old'cp objs/nginx '/usr/local/nginx/sbin/nginx'
test -d '/usr/local/nginx/conf'         || mkdir -p '/usr/local/nginx/conf'
cp conf/koi-win '/usr/local/nginx/conf'
cp conf/koi-utf '/usr/local/nginx/conf'
cp conf/win-utf '/usr/local/nginx/conf'
test -f '/usr/local/nginx/conf/mime.types'      || cp conf/mime.types '/usr/local/nginx/conf'
cp conf/mime.types '/usr/local/nginx/conf/mime.types.default'
test -f '/usr/local/nginx/conf/fastcgi_params'      || cp conf/fastcgi_params '/usr/local/nginx/conf'
cp conf/fastcgi_params      '/usr/local/nginx/conf/fastcgi_params.default'      
test -f '/usr/local/nginx/conf/nginx.conf'      || cp conf/nginx.conf '/usr/local/nginx/conf/nginx.co
nf'cp conf/nginx.conf '/usr/local/nginx/conf/nginx.conf.default'
test -d '/usr/local/nginx/logs' ||      mkdir -p '/usr/local/nginx/logs'
make[1]: Leaving directory `/usr/stay/nginx-1.8.1'

6.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

7.启动nginx服务

sudo service nginx start
sudo service nginx stop

这样，服务器配置已经完成，接下来需要进行测试,看是否推流成功！

8.下载ffmpeg源码，并安装（ffmpeg 命令查看是否安装成功）

    make
    make install

9.配置 nginx-rtmp 服务器，然后sudo service nginx restart重启
在打开 /usr/local/nginx/conf/nginx.conf，在末尾添加如下配置：

rtmp {
server {
        listen 1935;//监听端口
        chunk_size 4096;

        application live {
                live on;
                record off;
                exec ffmpeg -i rtmp://localhost/live/$name -threads 1 -c:v libx264 -profile:v baseline -b:v 350K -s 640x360 -f flv -c:a aac -ac 1 -strict -2 -b:a 56k rtmp://localhost/live360p/$name;
        }
        application live360p {
                live on;
                record off;
    }
}
}

10.进行推流
推流使用obs,ums或者github上的一些demo都可以！

11.在下载的windows版本的ffmpeg的bin ffplay

ffplay rtmp://120.77.182.106:1935/live/test
