MySQL menyertakan skrip keamanan yang memungkinkan Anda mengubah beberapa opsi konfigurasi default untuk meningkatkan keamanan MySQL.
Untuk menggunakan skrip keamanan, jalankan perintah berikut:
sudo mysql_secure_installationIni akan membawa Anda melalui serangkaian petunjuk yang menanyakan apakah Anda ingin membuat perubahan tertentu pada opsi keamanan instalasi MySQL Anda. Opsi ini meliputi:
- mengatur kata sandi pengguna root
- mengaktifkan VALIDASI KOMPONEN SANDI yang memastikan digunakannya sandi yang kuat
- Menghapus pengguna anonim
- Menonaktifkan root untuk login dari jarak jauh
- Menghapus database pengujian
Berikut adalah contoh keluaran dari server saya:
$ sudo 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
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: 2
Please set the password for root here.
New password:
Re-enter new password:
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.
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.
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.
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.
Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y
Success.
All done!Menguji Instalasi MySQL
Mari kita periksa versi mysql dengan perintah ini:
mysql -V
Sekarang Anda dapat Login sebagai root pengguna dan kata sandi yang ditentukan di atas.
