Nginx502 connect() failed (111:

配置好lnmp后，在浏览器中运行程序后，出现如下错误：

[error] 10903#10903: *44 connect() failed (111: Connection refused) while connecting to upstream, client: *.*.*.*, server:info.cloudtbank.com, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9001", host: "info.cloudtbank.com"

nginx 配置

server {
    listen       80;
    server_name info.cloudtbank.com;
    access_log  /home/log/access.log;
    error_log   /home/log/error.log;
    index index.php index.html index.htm;
    root  /home/var/www/;

    if (!-f $request_filename) {
         rewrite (.*) /index.php?__ip=$remote_addr;
    }

    if ($request_uri ~ " ") {
         return 444;
    }
    location ~ \.php$ {
 #       root           /home/var/www/;
        fastcgi_pass   127.0.0.1:9001;
        fastcgi_index  index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        #fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }
}

大概意思是你没有启动或者配置php-fpm.其中“ /home/var/www/”为网站根目录。
查看一下php-fpm状态 ，启动
/home/php/sbin/php-fpm

继续浏览网页，ok一切正常。 image.png
