➂Check mysql version

# mysql -V
mysql  Ver 8.0.32 for Linux on x86_64 (Source distribution)

1 2	# mysql -V mysql Ver 8.0.32 for Linux on x86_64 (Source distribution)

④Connect to the MySQL server and change the root user password

# mysql

mysql>alter user 'root'@'localhost' identified by 'password';

# mysql

mysql>alter user 'root'@'localhost' identified by 'password';

⑤Set basic policies
Use the "mysql_secure_installation" command to set the root user password and set some basic policies

# mysql_secure_installation

Securing the MySQL server deployment.

Enter password for user root:

VALIDATE PASSWORD COMPONENT can be used to test passwords
and improve security. It checks the strength of password
and allows the users to set only those passwords which are
secure enough. Would you like to setup VALIDATE PASSWORD component?

# Enable/disable password quality check
Press y|Y for Yes, any other key for No: y

There are three levels of password validation policy:

LOW    Length >= 8
MEDIUM Length >= 8, numeric, mixed case, and special characters
STRONG Length >= 8, numeric, mixed case, special characters and dictionary                  file

# Select strength if password quality check is enabled
Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 0   ←May be optional for each
Using existing password for root.

# Set MySQL root password
Estimated strength of the password: 100
Change the password for root ? ((Press y|Y for Yes, any other key for No) : y

New password:  ←　Any password

Re-enter new password:  ←　Same password again

# Confirmation that the password you entered is correct
Estimated strength of the password: 100
Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : y
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL 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.

# Whether to remove anonymous users or not
Remove anonymous users? (Press y|Y for Yes, any other key for No) : 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.

# Disable remote login for root user
Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y
Success.

By default, MySQL 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.

# Whether to delete the test database or not
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y
 - Dropping test database...
Success.

 - Removing privileges on test database...
Success.

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

# Whether to reload privilege information or not
Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y
Success.

All done!
