NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
|
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
|
|
In order to log into MariaDB to secure it, we'll need the current
|
password for the root user. If you've just installed MariaDB, and
|
you haven't set the root password yet, the password will be blank,
|
so you should just press enter here.
|
|
Enter current password for root (enter for none):
|
OK, successfully used password, moving on...
|
|
Setting the root password ensures that nobody can log into the MariaDB
|
root user without the proper authorisation.
|
|
Set root password? [Y/n] Y
|
New password:
|
Re-enter new password:
|
Password updated successfully!
|
Reloading privilege tables..
|
... Success!
|
|
|
By default, a MariaDB installation has an anonymous user, allowing anyone
|
to log into MariaDB 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.
|
|
Remove anonymous users? [Y/n] 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.
|
|
Disallow root login remotely? [Y/n] Y
|
... Success!
|
|
By default, MariaDB 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.
|
|
Remove test database and access to it? [Y/n] 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.
|
|
Reload privilege tables now? [Y/n] Y
|
... Success!
|
|
Cleaning up...
|
|
All done! If you've completed all of the above steps, your MariaDB
|
installation should now be secure.
|
|
Thanks for using MariaDB!
