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。

![format_png][]

mysql -u root -p   登录到mysql中。

[root@izbp10fk8pd9zjv9y2g9ajz etc]# mysql -u root -p
    Enter password:

use mysql;

select host from user where user='root';

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';

刷新配置。

flush privileges;

最后如图。链接成功。
