Create non-root users in MySQL (detailed explanation)

1. Use the root account to log in to the MySQL server:

mysql -u root -p

2. Create a new user account using the command CREATE USER.

For example, the following command creates a

• User: newuser
• Password: xxxxxx

CREATE USER 'newuser'@'localhost' IDENTIFIED BY 'xxxxxx';

Notice:

• The @'localhost' part of the command specifies that the user is only allowed to connect from the local host.
• If you want to allow connections from any host, you can use 'newuser'@'%'.

CREATE USER 'newuser'@'%' IDENTIFIED BY 'xxxxxxx';	#任何主机的连接

4. Use the command GRANT to grant permission to the new user.

For example, the following command grants all mydatabase privileges to newuser on the database named test:

GRANT ALL PRIVILEGES ON test.* TO 'newuser'@'localhost';

5. Finally, refresh the permissions for the changes to take effect immediately.

FLUSH PRIVILEGES;
