MySQL Security Configuration Wizard mysql_secure_installation

After installing mysql-server, you will be prompted to run mysql_secure_installation. Running mysql_secure_installation will execute several settings:
A) set a password for the root user
B) Delete anonymous accounts
C. Cancel the remote Logon of the root user.
D) Delete the test database and access permissions to the test database.
E) refresh the authorization table to make the modification take effect.

These settings can improve the security of the mysql database. We recommend that you run mysql_secure_installation once mysql is installed in the production environment. For detailed steps, see the following command:

Copy codeThe Code is as follows:
[Root @ server1 ~] # Mysql_secure_installation
