mysql set password for root

MySQL is a relational database management system that can help users store, manage and retrieve various data. The default administrator account in MySQL is root. This account has very high permissions and can perform various operations. In a production environment, in order to ensure the security of the database, a strong password needs to be set for the root account.

MySQL steps to set root password

Step 1: First log in to MySQL

Enter the following command in the terminal to enter the MySQL console:

sudo mysql

If you are prompted for a password after entering this command, please enter the password of your root user.

Step 2: Change the password

After we enter the MySQL console, we can start to change the password of the root user. Follow the command below to set the password:

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'new_password';

'new_password' is the new password you want to set.

Step 3: Refresh permissions

After executing the above command, you need to refresh the permissions so that MySQL can use the new password to verify the identity of the root account. Enter the following command in the MySQL console:

FLUSH PRIVILEGES;

Step 4: Exit MySQL

After completing the password change, you can exit MySQL through the following command:

exit

Now you have successfully changed the password of the root account.

How to set a secure MySQL root password

For a network-based service, password security is very important. A hacker with a compromised root account can easily access your database, which can have disastrous consequences for users and the company. Therefore, when setting the MySQL root password, you need to abide by the following rules:

1. The password must be no less than 10 characters long
2. The password must be composed of letters, numbers, and symbols
3. Avoid using easy-to-guess passwords, such as birthday, 123456, etc.
4. Avoid using public information, such as company name or your name
5. Change passwords regularly

If If you're not sure how to set a strong password, you can use some password generator tools, such as 1Password or LastPass.
