nginx配置文件:

server {
        listen       80;
            root      /var/www/html;
        server_name  localhost;
        charset utf-8;
        index  index.html index.htm index.php;
        location ~ .*.(php|php5)?${
            fastcgi_pass 127.0.0.1:9000;
            fastcgi_index index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include fastcgi.conf;
            }
}

$document_root 的参数是由root /var/www/html那一行定义的

查看日志发现报错:mysql_connect()

Call to undefined function mysql_connect() in /var/www/html/test.php on line 2" while reading response header from upstream

可能是由于缺少php-mysql插件导致的,可以yum安装,然后重启php-fpm服务

测试nginx与php是否连接成功:

vim test.php

测试php与mysql是否连接成功:

vim testdb.php
