LNMP时,出现502 Bad Gateway的错误提示

因为工作需要,要在ubuntu中安装LNMP环境,在这里,php是最新版本php7.1。一切都进展得很顺利,安装完成后,在浏览器中输入http://127.0.0.1/info.php,出现了502 Bad Gateway的错误提示。

LNMP时,出现502 Bad Gateway的错误提示

打开/var/log/nginx 下的error.log,发现提示为:2017/07/15 14:46:47 [error] 1228#0: *8 connect() failed (111: Connection refused) while connecting to upstream, client: 127.0.0.1, server: localhost, request: "GET /info.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000",
host: "127.0.0.1"。

进入/etc/php/7.1/fpm/pool.d下,打开www.conf文件,找到listen这一行,发现listen = /run/php/php7.1-fpm.sock。(我的php7.1-fpm.sock 在/var/run/php/php7.1-fpm.sock下,于是改成了/var/run/php/php7.1-fpm.sock)

进入/etc/nginx/sites-available目录下,打开default文件,里面的location配置为:

location ~ \.php$ {

        #       fastcgi_split_path_info ^(.+\.php)(/.+)$;

        #       # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini

        #

        #       # With php5-cgi alone:

               fastcgi_pass 127.0.0.1:9000;

        #       # With php5-fpm:

        #         fastcgi_pass unix:/var/run/php/php7.1-fpm.sock;

        #         include fastcgi_params;

        #         fastcgi_index index.php;

         #       include fastcgi_params;

        #}

        # deny access to .htaccess files, if Apache's document root

        # concurs with nginx's one

        #

        #location ~ /\.ht {

        #       deny all;

        }

很明显,default文件中的l监听方式和www.conf文件中的不一样,因此我改为:

location ~ \.php$ {

        #       fastcgi_split_path_info ^(.+\.php)(/.+)$;

        #       # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini

        #

        #       # With php5-cgi alone:

        #       fastcgi_pass 127.0.0.1:9000;

        #       # With php5-fpm:

                fastcgi_pass unix:/var/run/php/php7.1-fpm.sock;

                fastcgi_split_path_info ^(.+\.php)(/.*)$;

                include fastcgi_params;

                fastcgi_index index.php;

                include fastcgi_params;

        #}

        # deny access to .htaccess files, if Apache's document root

        # concurs with nginx's one

        #

        #location ~ /\.ht {

        #       deny all;

        }

最终default文件如下:

保存这个配置后,重启Nginx ;service nginx restart,然后刷新浏览器,最后的结果展示如下:
