# CentOS 7里如何编译安装Nginx-RTMP直播插件？

## 安装依赖包

```
yum -y install pcre pcre-devel openssl openssl-devel zlib zlib-devel unzip
```


## 下载最新版nginx源码

```
mkdir downloads/
cd downloads/
wget http://nginx.org/download/nginx-1.9.9.tar.gz
```


## 下载Nginx-RTMP插件源码

```
wget https://github.com/arut/nginx-rtmp-module/archive/master.zip -O rtmp.zip
```


## 解压缩源码

```
unzip rtmp.zip
tar -zxvf nginx-1.9.9.tar.gz
```


## 配置Nginx

```
cd nginx-1.9.9/
./configure --add-module=../nginx-rtmp-module-master/ --with-http_realip_module
```


## 编译安装Nginx

```
make && make install
```

确认安装成功：
```
/usr/local/nginx/sbin/nginx -v
```


## 启动nginx

```
/usr/local/nginx/sbin/nginx
```

如果需要用systemctl来启动nginx，
请修改nginx的服务配置文件：
```
cp /usr/lib/systemd/system/nginx.service /usr/lib/systemd/system/nginx_backup.service
vim /usr/lib/systemd/system/nginx.service
```

保存后reload配置：
```
systemctl daemon-reload
```

再尝试用systemctl启动nginx服务：
```
systemctl stop nginx
systemctl start nginx
```
