简单的例子

```
server {
    listen 80 default_server;
    listen [::]:80 default_server;

    root /var/www/html;

    index index.php index.html index.htm;

    server_name _;

    location / {
        if (!-e $request_filename) {
            rewrite ^/(.*)$ /index.php?$1 last;
        }
    }

    location ~ \.(css|js|jpg|png|woff2|svg)$ {
        expires 30d;
        access_log off;
    }
    
    location ~ \.php$ {
        fastcgi_pass 127.0.0.1:9000;
        #fastcgi_pass unix:/run/php7.2-fpm.pid;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        fastcgi_param  PATH_INFO  $fastcgi_path_info;
        fastcgi_param  PATH_TRANSLATED  $document_root$fastcgi_path_info;
        include snippets/fastcgi-php.conf;

    }

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    location ~ /\.ht {
        deny all;
    }
}
```

使用cron进行自动更新。在服务器上增加。每天早上1点进行更新。
# crontab -e 

```
0 1 * * * curl http://localhost/update
```
