After MySQL is installed, MySQL directly enters the database

After setting the remote connection, the following error will be prompted:

Prompt: error 1044 (42000): access denied for user ‘@’localhost’ to database ‘MySQL’. The reason is that in the user table of MySQL database, there is an account whose user name is empty, that is, an anonymous account. In fact, it logs in anonymously. It can be seen from the “@ ‘localhost” in the error prompt. Therefore, the solution is shown in method 2

method 1: (applicable to those with incorrect password)

0. Ideas:

By shielding the login password of MySQL, first enter into mysql, and then update the password through the update command

1. Close mysql

Service mysqld stop/Linux

Net stop MySQL// window

2. Shielding permissions
mysqld_ Safe — skip grant table// in Linux

Mysqld — skip grant table// window

Or use the following command

mysqld_ safe –user=mysql –skip-grant-tables –skip-networking & // Using Linux

the screen appears: starting demo from

3. Open a new terminal and input
?MySQL – U root MySQL
MySQL > UPDATE user SET Password=PASSWORD(‘newpassword’) where USER=’root’;
mysql> FLUSH PRIVILEGES; // Remember this sentence in the update command, otherwise, if you close the previous terminal, the original error will appear again
MySQL & gt\ q

method 2: (applicable to the presence of empty password)

0. Ideas

Sometimes, although MySQL has an account and a corresponding password. However, due to the existence of a blank password, it will log in to the blank password by default

If you need to delete the account with empty password, you can view all the accounts through the following command

select host,user,password from user;

1. Close MySQL
?Service mysqld stop

2. Shield permissions
?Mysqld_ Safe — skip grant table
the screen appears: starting demo from

3. Start a new terminal to input
# MySQL – U root MySQL
MySQL > delete from user where USER=”; // Delete empty password
MySQL > FLUSH PRIVILEGES;// Remember this sentence, otherwise, if you close the previous terminal, the original error will appear again
MySQL > exit

4. Finally solve the startup error

Check the MySQL startup log and find that port 3306 is occupied. Kill the MySQL process and restart the MySQL service
