Wamp-PHPMyAdmin 用户问题
MySQL 数据库 用户 WAMP 权限
mysql_connection 连接数据库如果使用root用户的话是可以连接到的~~
但是如果使用我新建的一个user用户就连接不上了~~
请问这是什么原因??我猜测是不是mysql配置只允许root使用??
但是不太会改~~希望大神指点一下~~
回复讨论(解决方案)
是PHPMyAdmin的问题 还是php里边链接数据库的问题?
如果是前者的话
用户概况
用户 主机 密码 全局权限 授权 操作
任意 % -- USAGE 否 编辑权限 编辑权限 导出 导出
任意 localhost 否 USAGE 否 编辑权限 编辑权限 导出 导出
root 127.0.0.1 否 ALL PRIVILEGES 是 编辑权限 编辑权限 导出 导出
root ::1 否 ALL PRIVILEGES 是 编辑权限 编辑权限 导出 导出
root localhost 是 ALL PRIVILEGES 是 编辑权限 编辑权限 导出 导出
test localhost 是 USAGE 否 编辑权限 编辑权限 导出 导出
root是可以添加新用户并设置权限的
后者的话 再描述清楚些...
报什么错,你新建的用户给他授权了吗
root localhost 否 ALL PRIVILEGES 是
user % 是 ALL PRIVILEGES 否
一个是root的一个是user的 第一个不同是密码~~root没有密码,应该不是原因
后面那个是授权,好像是授权的问题~~我看一下~~
报什么错,你新建的用户给他授权了吗
好像是授权的问题,我看一下~~谢谢~~
报什么错,你新建的用户给他授权了吗
mysql_connect(): Access denied for user 'user'@'localhost'
好像还是不对~~这是报的错~~应该还是用户的问题,因为root和空密码是可以的
用user登陆后 show grant ; 看看。
如果是权限不够,则执行
grant all on *.* to user@localhost;
