[2] MySQL Server – Konfiguracja

W pierwszej kolejności dodajemy wpis do [/etc/rc.conf] informujący system o automatycznym starcie serwera MySQL.

root@vfbsd01:~ # mcedit /etc/rc.conf
# dodaj na końcu
mysql_enable="YES"

Nastepnie uruchamiamy ręcznie serwer MySQL.

root@vfbsd01:~ # service mysql-server start
Starting mysql.
root@vfbsd01:~ # service mysql-server status
mysql is running as pid 2153.

Jeśli wszystko jest OK, należy uruchomić [mysql_secure_installation], aby wprowadzić ustawienia początkowe.

root@vfbsd01:~ # mysql_secure_installation

Securing the MySQL server deployment.

Connecting to MySQL using a blank password.

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?

Press y|Y for Yes, any other key for No: y # wpisz [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

Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 1 # wybierz złożoność hasła, ja wybrałem [1]
Please set the password for root here.

New password: # wpisz hasło root’a dla MySQL
Re-enter new password: # ponownie wpisz hasło root’a dla MySQL

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 # wpisz [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.

Remove anonymous users? (Press y|Y for Yes, any other key for No) : y # wpisz [y] jeśli chcesz usunąć użytkownika anonimowego, w przeciwnym razie wpisz [n]
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? (Press y|Y for Yes, any other key for No) : y # wpisz [y] jeśli nie chcesz pozwolić logować się root’owi zdalnie, w przeciwnym razie wpisz [n]
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? (Press y|Y for Yes, any other key for No) : y # wpisz [y] jeśli chcesz usunąć bazę danych [test], w przeciwnym razie wpisz [n]
- 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? (Press y|Y for Yes, any other key for No) : y # wpisz [y] jeśli chcesz przeładować uprawnenia, w przeciwnym razie wpisz [n]
Success.

All done!

Sprawdzimy teraz czy wszystko działa poprawnie.
