• Install MariaDB Sever

sudo apt -y install mariadb-server

• Secure MariaDB database dengan mariadb Wizards

mariadb-secure-installation

root@radiusdev:~# mariadb-secure-installation
 
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
haven't set the root password yet, you should just press enter here.
 
Enter current password for root (enter for none):  [ENTER]
OK, successfully used password, moving on...
 
Setting the root password or using the unix_socket ensures that nobody
can log into the MariaDB root user without the proper authorisation.
 
You already have your root account protected, so you can safely answer 'n'.
 
Switch to unix_socket authentication [Y/n] [n]
 ... skipping.
 
You already have your root account protected, so you can safely answer 'n'.
 
Change the 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!

• Buat Database Dan User Untuk FreeRadius

sudo mysql -u root

CREATE DATABASE radius;
CREATE USER 'radius'@'localhost' IDENTIFIED BY 'PasswordYangKuat123';
GRANT ALL PRIVILEGES ON radius.* TO 'radius'@'localhost';
FLUSH PRIVILEGES;
quit;

• import SQL schema file ke Database yang kita buat sebelumnya.

sudo mysql -u root -p radius < /etc/freeradius/3.0/mods-config/sql/main/mysql/schema.sql

• Enable SQL module pada FreeRADIUS.

sudo ln -s /etc/freeradius/3.0/mods-available/sql /etc/freeradius/3.0/mods-enabled/

• Edit Module SQL Untuk Dapat terhubung dengan Database yang telah kita buat

sudo nano /etc/freeradius/3.0/mods-enabled/sql

• Ubah opsi database dari sqlite (default) ke mysql(mariadb)

# Rubah 
        dialect = "sqlite"
# Ke
        dialect = "mysql"

• coment driver = “rlm_sql_null”

        driver = "rlm_sql_null"
#       driver = "rlm_sql_${dialect}"

• uncoment driver = “rlm_sql_${dialect}”

        driver = "rlm_sql_null"
#       driver = "rlm_sql_${dialect}"

• Sebab koneksi database bersifat local configurasi tls dapat di comment

• Uncomment connection info dan ganti sesuai dbname dan passwrod yang telah dibuat
