The specified database user/password combination is rejected: [28000][1045]解决方案之一

问题：DataGrip 测试链接时出现下图情况

根据字面意思，mysql的root密码错了。

解决过程

 1.   mysql_secure_installation

2.

 要求输入当前密码，输入的是第一张图报错的密码，验证成功，继续下一步。

3.

这里询问是否更改密码，输入Y

输入的还是原来的密码

4. 

询问是否移除匿名用户，输入Y。

5. 

询问是否禁止root的远程连接，输入n。

6. 

 询问是否删除test数据库，输入n。

7.

询问是否现在重新加载权限表  这里不小心按到ctrl+C。

8.此时再测试链接，成功。（文章第一张图是别人的，所以ip不一样）

[root@master ~]# mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none): 
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
Enter current password for root (enter for none): 
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

You already have a root password set, so you can safely answer 'n'.

Change the root password? [Y/n] Y
New password: 
Re-enter new password: 
Password updated successfully!
Reloading privilege tables..
 ... Success!


By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] Y
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] n
 ... skipping.

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] n
 ... skipping.

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] ^C
Aborting!

Cleaning up...
