阿里云上安装的mysql,发现用本地电脑的navicat链接不上。通过了解知道了原因,小二在此写了一篇,省的以后自己在碰到。

错误如图。

is not allowed to connect to this mysql server

mysql -u root -p   登录到mysql中。

  1.  
    [root@izbp10fk8pd9zjv9y2g9ajz etc]# mysql -u root -p
  2.  
    Enter password:
use mysql;

is not allowed to connect to this mysql server

select host from user where user='root';

is not allowed to connect to this mysql server

修改帐号不允许从远程登陆,只能在localhost。这个时候只要在localhost的那台电脑,登入MySQL后,更改 "mysql" 数据库里的 "user" 表里的 "host" 项,从"localhost"改称"%"

update user set host = '%' where user ='root';

is not allowed to connect to this mysql server

刷新配置。

flush privileges;

is not allowed to connect to this mysql server

最后如图。链接成功。

is not allowed to connect to this mysql server
