MySQL server提示信息，不能远程连接数据库。
安装完MySQL后，远程连接数据库的时候，出现 ERROR 1130 (HY000): Host '192.168.0.32'is not allowed to connect to this MySQL server提示信息，不能远程连接数据库。
于是在网上搜了下
用下面的方法解决：
这个时候只要在MySQL服务器上登入mysql后，更改 "mysql" 数据库里的 "user" 表里的 "host" 项，从"localhost"改称"%"（或新增一条记录），正式环境建议指定为应用服务器的IP地址，比如'192.168.0.32'。
mysql -u root -pvmware
mysql>use mysql;
mysql>update user set host = '%' where user = 'root'; //这个命令执行错误时可略过
