# 安装nginx+http-flv(rtmp服务器)
#### 操作步骤
下载[安装指导](https://github.com/winshining/nginx-http-flv-module/blob/master/README.CN.md)。
1. 单击[下载路径](https://openssl-library.org/source/old/1.1.1)，安装依赖项openssl，这里选择1.1.1g。
   
   ![](https://support.huaweicloud.com/bestpractice-iotedge/figure/zh-cn_image_0000001340947432.png "点击放大")
   假设将下载文件放至"/home"目录下并解压，依次执行以下命令进行openssl的编译安装。
   ```
   ./config no-asm -shared
   make –j4
   make install
   ```
   
   
2. 下载nginx和nginx-http-flv-module。 
   安装指导以及下载链接：<https://github.com/winshining/nginx-http-flv-module/blob/master/README.CN.md>
   ![](https://support.huaweicloud.com/bestpractice-iotedge/public_sys-resources/note_3.0-zh-cn.png)
   上述的包均为源码，需要将nginx和nginx-http-flv-module一起编译，接下来进行编译。
   
   
3. 将上述的压缩包分别解压到"/home"目录下。

4. 使用以下命令进行编译。 
   ```
   ./configure --add-module=/home/nginx-http-flv-module-master
   make –j4
   make install
   ```
   默认nginx安装在/usr/local/nginx
   
   
5. 配置nginx。 
   配置文件为nginx.conf
   Nginx的配置目录为/usr/local/nginx/conf/
   可以使用下面的文件直接覆盖nginx.conf
   ![](https://support.huaweicloud.com/bestpractice-iotedge/figure/zh-cn_image_0000001340956600.png "点击放大")
   上面两个配置分别表示rtmp服务器地址监听地址以及appname。
   **配置文件**：
   ```
   #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;

       worker_connections  1024;

       #
       #server {

   rtmp {

                   listen 1985;
                   application edge_video{
                           live on;
   gop_cache on;
                   }
   application hls {
   live on;
   hls on;
   hls_path /tmp/hls;
   }
           }
   }
   ```
   
   
6. 运行nginx。 
   ```
   export LD_LIBRARY_PATH=/usr/local/lib64/:${LD_LIBRARY_PATH}
   cd /usr/local/nginx/sbin
   ./nginx
   ```
