PHP学习过程中遇到的坑

使用windows服务器，phpstuday 第一天服务器配置好访问没有问题。第二天发现访问php文件nginx会报错，以下是错误日志：
2018/12/08 16:26:34 [error] 35824#34560: *55 upstream timed out (10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond) while connecting to upstream, client: 183.158.123.143, server: xxxx, request: “GET / HTTP/1.1”, upstream: “fastcgi://127.0.0.1:9000”, host: “xxx”
2018/12/08 16:31:18 [error] 35824#34560: *118 upstream timed out (10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond) while connecting to upstream, client: 183.158.123.143, server: xxxx, request: “GET / HTTP/1.1”, upstream: “fastcgi://127.0.0.1:9000”, host: “xxx”
网上搜索很多办法配置没有结果。
使用cmd查看 netstat -ano 发现9000端口关闭
重启服务器后解决问题
以下是nginx配置

	location ~ \.php(.*)$ {
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_split_path_info  ^((?U).+\.php)(/?.+)$;
            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        fastcgi_params;
        }

暂时还没找到原因，哪位大神有好的解决办法或者知道原因，请私聊或者评论
