## 介紹

>本文使用的流媒體伺服器的搭建是基於rtmp（Real Time Message Protocol）協議的，rtmp協議是應用層的協議，要依靠底層的傳輸層協議，比如tcp協議來保證資訊傳輸的可靠性。

>注意事項：由於內網測試   關閉防火牆與SElinux

## Nginx部署

`Nginx需要nginx-rtmp-module模組,yum安裝沒有此模組,所以本次使用原始碼安裝`

```
## 安裝Nginx所需依賴
[root@localhost ~]# yum install gcc gcc-c++ make automake autoconf libtool pcre* zlib openssl openssl-devel git

## 下載所需安裝包
[root@localhost ~]# cd  /home/artc
[root@localhost artc]# mkdir Nginx #建立原始碼目錄 後面的原始碼都放在這個目錄
[root@localhost artc]# cd Nginx
[root@localhost Nginx]# git clone https://github.com/nginx/nginx.git #從github伺服器上將nginx的原始碼下載下來
[root@localhost Nginx]# git clone https://github.com/arut/nginx-rtmp-module.git #將rtmp模組的原始碼下載下來
```

```
## 編譯安裝Nginx
[root@localhost ~]# cd /home/artc/Nginx/nginx
[root@localhost nginx]# ./auto/configure --prefix=/usr/local/nginx \
        --with-http_v2_module \
        --with-http_flv_module \
        --with-http_mp4_module \
        --add-module=../nginx-rtmp-module/
[root@localhost nginx]# make && make install 
```

```
## 更改配置檔案
[root@localhost nginx]# cd /usr/local/nginx/conf
[root@localhost conf]# vim nginx.conf
#在http模組外新增
rtmp  {
    server  {
        listen 1915;
        timeout 20s;

application live  {
            live on;
            record off;
        }

## 一個音影片模組
        application anyrtc  {
            live on;
            hls  on;
            hls_path temp/zyh;
            hls_playlist_length 5s;
            hls_fragment 1s;
        }

application vod  {
            play /var/flvs;
        }

application vod_http  {
            play http://伺服器IP/vod;
        }

## 一個音影片模組
        application hls  {
            live on;
            hls on;
            record off;
            hls_path /tmp/hls;
            hls_playlist_length 5s;
            hls_fragment 1s;
        }
    }
}

## 啟動Nginx
[root@localhost nginx]# /usr/local/nginx/sbin/nginx
```

[root@localhost SRS-CentOS7-x86_64-3.0.168]# ./INSTALL 
[root@localhost SRS-CentOS7-x86_64-3.0.168]# systemctl start srs.service

## 配置檔案在/usr/local/srs
[root@localhost SRS-CentOS7-x86_64-3.0.168]# cd /usr/local/srs/conf
[root@localhost conf]# vim srs.conf
# main config for srs.
# @see full.conf for detail config.

## ZLMediaKit部署

> 下載地址： git clone --depth 1 https://gitee.com/xia-chu/ZLMediaKit

```
## 準備環境
[root@localhost artc]# yum -y update

## gcc和yasm需要高版本  小編用的是gcc4.8.5 yasm1.2.0
[root@localhost artc]# yum -y update   yasm  gcc* 
[root@localhost artc]# yum -y install  openssl-devel  SDL-devel

## 編譯安裝cmake 3.8.2
[root@localhost ~]# cd /home/artc
[root@localhost artc]# wget https://cmake.org/files/v3.8/cmake-3.8.2.tar.gz
[root@localhost artc]# tar zxvf cmake-3.8.2.tar.gz
[root@localhost artc]# cd cmake-3.8.2
[root@localhost cmake-3.8.2]# ./bootstrap
[root@localhost cmake-3.8.2]# gmake
[root@localhost cmake-3.8.2]# gmake install

## 國內庫比較快
[root@localhost ~]# cd  /home/artc 
[root@localhost artc]# git clone --depth 1 https://gitee.com/xia-chu/ZLMediaKit
[root@localhost artc]# cd ZLMediaKit
#千萬不要忘記執行這句命令
[root@localhost ZLMediaKit]# git submodule update --init

## 編譯安裝
[root@localhost ZLMediaKit]# mkdir build
[root@localhost ZLMediaKit]# cmake .
[root@localhost ZLMediaKit]# make -j4

## ZLMediaKit服務目錄
[root@localhost ZLMediaKit]# cd release/linux/Debug

## 配置檔案
[root@localhost Debug]# vim config.ini 
[rtmp]  ##228行左右
handshakeSecond=15
keepAliveSecond=15
modifyStamp=0
port=1955     				## 預設1935   埠衝突 修改了1955
sslport=0

## 程式啟動
[root@localhost Debug]# ./MediaServer	   ## 前臺啟動
[root@localhost Debug]# ./MediaServer -d & ## 後臺啟動

## 軟連線
[root@localhost Debug]# ln -sf /home/ZLMediaKit/release/linux/Debug/MediaServer /usr/bin/
```
