在线请问： connect() failed (111: Connection refused) while connecting to upstream

[kmdd33]

安装环境：openresty，php7，mysql，centos7 出现的问题：IP，ip ／ test.html 和 ip/50x.html 都显示正常，但是 ip/info.php 无法显示，并且无法进入安装程序目录。请问如何解决？

error.log 显示错误：

2018/06/09 09:46:56 [error] 825#825: *123 connect() failed (111: Connection refused) while connecting to upstream, client: 113.118.xxx.228, server: 173.255.247.37, request: "GET /info.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "xxx.255.xxx.xxx"

／ etc ／ php-fpm.d ／ www.conf 里面我改成了这样：

listen = /var/run/php-fpm/php-fpm.sock listen = 9000

刚才把／ etc ／ php-fpm.d ／ www.conf 里面改成了：

listen = /var/run/php-fpm/php-fpm.sock
listen = 9000

改成了：listen = 127.0.0.1

php-fpm 启动正常。但是但是 ip/info.php 无法显示，并且无法进入安装程序 ip/install 目录

输入：netstat -lntp | grep 9000

却没有任何提示
