sendfile on;
keepalive\_timeout 65;
server {
listen 81;
server\_name localhost;
location / {

index index.html index.htm;
}
location ~ \\.php$ {
fastcgi\_pass 127.0.0.1:9000;
fastcgi\_index index.php;
fastcgi\_param SCRIPT\_FILENAME /data/php/$fastcgi\_script\_name; #当请求资源是php后缀的文件时，在目录/data/php中查找
include fastcgi\_params;
}
}
}
```
* php-fpm保持默认状态
## 3、运行
### 3.1、启动php-fpm

## 4、流程
### 4.1、流程图
### 4.2、文字描述如下
* 访问http://192.168.0.200:81/index.php
* Nginx查看nginx.conf配置文件
* 加载nginx的fast-cgi模块
* php-fpm 监听127.0.0.1:9000
* php-fpm 接收到请求，启用worker进程处理请求
* php-fpm 处理完请求，返回给nginx
