MariaDB adalah sistem manajemen basis data relasional cabang dari MySQL. Sama seperti pendahulunya MariaDB juga gratis dan open source di bawah lisensi GNU GPL. MariaDB dikembangkan oleh komunitas dan didukung secara komersial. MariaDB dikembangkan oleh beberapa pengembang asli MySQL.
Karena, ini adalah pecahan awal dari MySQL, MariaDB telah ditingkatkan dengan banyak fitur baru. Saat ini, versi stabil 10.3.12 tersedia untuk digunakan.
Paket MariaDB dapat dilihat pada MariaDB Download. Kita dapat menambahkan MariaDB yum repository.
# nano /etc/yum.repos.d/mariadb.repo
Lalu isikan :
[mariadb] name=MariaDB baseurl=http://yum.mariadb.org/10.3/centos7-amd64 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck=1 enabled=1
Sebelum menggunakan repositori yum MariaDB, kita harus mengimpor kunci publik GPG untuk memverifikasi digital signature dari paket-paket dalam repositori ini.
Meskipun, tidak perlu mengimpor kunci publik GPG secara manual. Kunci publik GPG akan diinstal secara otomatis oleh yum, ketika menginstal paket dari repositori yum MariaDB untuk pertama kalinya.
# rpm --import https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
Buat cache yum menggunakan perintah berikut.
# yum makecache fast
Instal server MariaDB menggunakan perintah :
# yum install -y mariadb-server
Setelah proses instalasi selesai lakukan perintah mulai dan aktifkan layanan MariaDB.
# systemctl start mariadb # systemctl enable mariadb
Konfigurasikan database MariaDB.
# mysql_secure_installation

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!
