This article mainly introduces the example analysis of the failure of the idea operation database in ubuntu 18.04. It has certain reference value. Interested friends can refer to it. I hope you will have a lot of gains after reading this article. Let Xiaobian take you to understand it together.

Possible cause: Insufficient authority

I found that I need root privileges every time I enter mysql at terminal. Otherwise "Access denied for user 'root'@'localhost'" is the same even in navicat. Ordinary users simply cannot connect. Always report 2002 error. But if I am root user, log in there is no problem, it is very fan!

So I suspect that my idea does not have root privileges caused. After all, I opened idea with normal user rights.

With terminal login mysql method (root can be replaced with other user names)

via :~$ mysql -u root -p

Create a normal new user with all permissions to add, delete, and search. Use this username and password to log in to idea. It works! Enter mysql with root privileges

via :~$ sudo suvia :~$ mysql -u root -p

increase user

CREATE USER 'username'@'host' IDENTIFIED BY 'password';

Authorization (I grant all permissions, so it is ALL to modify the situation)

GRANT ALL ON *.* TO 'username'@'localhost';

refresh

flush privileges; Thank you for reading this article carefully, I hope Xiaobian shared "Ubuntu 18.04 idea operation database failure example analysis" This article is helpful to everyone, but also hope that everyone more support, pay attention to the industry information channel, more relevant knowledge waiting for you to learn!
