nginx伺服器

nginx伺服器是開源的高效能的http伺服器，反向代理伺服器，是俄羅斯的大佬開發的，在國內許多公司應用比較多，具體看百科！

反向代理伺服器：代理伺服器接收internet請求，然後改代理伺服器將請求轉向內部的伺服器，內部伺服器將處理的結果返回代理伺服器，這個代理伺服器就為反向代理伺服器！

rtmp

實時訊息傳輸協議（real time messaging protocol），主要應用在流媒體傳輸，實時音視訊通訊的協議！

nginx伺服器與rtmp mudle

nginx伺服器支援許多功能模組，比如http–mudle,rtmp–mudle等等，不同的mudle佔用不同的埠，通過埠，客戶端就可以與nginx的mudle進行通訊！我們對音視訊通過rtmp協議進行推流到nginx伺服器，所以需要安裝nginx支援的rtmp–mudle！

安裝配置

開始我是在redhat版本上進行安裝的,遇到的許多問題:
    紅帽redhat沒有apt-get命令(ubantu),使用yum一直提示沒有可用的資源,就安裝不了編譯依賴工具
    去github下載指令碼的時候,不知道什麼原因也一直down不下來!
於是去下載apt-get,瞎搞了半天,沒有成功,就這樣前前後後折騰了幾天,實在不想折騰了,就去阿里雲買了一個低配置的雲主機,一個月45左右,接下來環境配置一路暢通!

1.下載nginx,rtmp支援的編譯依賴工具

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

2.下載nginx,以及rtmp原始碼,然後解壓

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

3.進行解壓後的ningx目錄,執行configue檔案

新增http,rmpt模組
./configure --with-http_ssl_module --add-module=../nginx-
rtmp-module-master

進行一些檔案檢測

產生MakeFile檔案

nginx安裝目錄:/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 fastcgi temporary files: "fastcgi_temp"
  nginx http uwsgi temporary files: "uwsgi_temp"
  nginx http scgi temporary files: "scgi_temp"
 

4.編譯MakeFile:make

make


產生一些臨時檔案
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.編譯完成之後，進行安裝：make install

make install

進行檔案的拷貝，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.設定開機啟動

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.啟動nginx服務

sudo service nginx start
sudo service nginx stop

這樣，伺服器配置已經完成，接下來需要進行測試,看是否推流成功！

8.下載ffmpeg原始碼，並安裝（ffmpeg 命令檢視是否安裝成功）

    make
    make install

9.配置 nginx-rtmp 伺服器，然後sudo service nginx restart重啟
在開啟 /usr/local/nginx/conf/nginx.conf，在末尾新增如下配置：

rtmp {
server {
        listen 1935;//監聽埠
        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.進行推流
推流使用obs,ums或者github上的一些demo都可以！

11.在下載的windows版本的ffmpeg的bin ffplay

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