#mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MySQL to secure it, we'll need the current
password
for
the root user. If you've just installed MySQL, 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 MySQL
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 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.
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, 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.
Remove
test
database and access to it? [Y
/n
] y
- Dropping
test
database...
ERROR 1008 (HY000) at line 1: Can
't drop database '
test
'; database doesn'
t exist
... Failed! Not critical, keep moving...
- 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!
All
done
! If you've completed all of the above steps, your MySQL
installation should now be secure.
Thanks
for
using MySQL!
Cleaning up...
