Cara Install MariaDB di CentOS

Setelah sebelumnya saya share cara untuk install MariaDB di Debian, kali ini saya akan share cara untuk melakukan installasi MariaDB di CentOS.
Untuk installasi MariaDB di CentOS juga sangat mudah lho, kamu tinggal menjalankan perintah yum install mariadb.
Tetapi versi MariaDB dari official repo CentOS ini cukup lama, yaitu MariaDB 5.5.
Jadi kali ini saya akan menunjukkan cara untuk menginstall MariaDB versi terbaru yaitu MariaDB 10.3.

Step 1: Install repository MariaDB

Untuk menginstall MariaDB 10.3, yang harus dilakukan pertama adalah menginstall repository MariaDB.
Jika kamu menggunakan CentOS 6, maka bisa menggunakan perintah:

cat << EOF > /etc/yum.repos.d/MariaDB.repo
# MariaDB 10.3 CentOS repository list - created 2018-07-28 04:18 UTC
# http://downloads.mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.3/centos6-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1
EOF

Atau bisa menggunakan perintah berikut jika menggunakan CentOS 7:

cat << EOF > /etc/yum.repos.d/MariaDB.repo
# MariaDB 10.3 CentOS repository list - created 2018-07-28 04:18 UTC
# http://downloads.mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.3/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1
EOF

Step 2: Install MariaDB

Sekarang kita bisa menginstall paket MariaDB server dan juga MariaDB client dengan menggunakan yum

yum install MariaDB-server MariaDB-client

Setelah MariaDB server dan client terinstall, sekarang aktifkan service MariaDB saat booting dan juga jalankan servicenya.

Untuk CentOS 6:

chkconfig mariadb on
service mariadb start

Dan untuk CentOS 7:

systemctl enable mariadb
systemctl start mariadb

Step 3: Mengamankan installasi MariaDB

Ini step yang penting ya, jangan lupa untuk mengamankan MariaDB servermu, caranya dengan menjalankan perintah:

mysql_secure_installation

Nantinya akan muncul prompt seperti dibawah. Pada bagian Enter current password for root (enter for none): karena MariaDB server ini adalah installasi baru maka bisa langsung tekan enter saja.
Lalu isikan root password MariaDB, hapus anonymous user, batasi akses user root untuk localhost saja dan hapus database test.

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
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!

Terus apa lagi?

Selamat, MariaDB sudah terinstall di servermu dan kamu bisa menggunakan perintah ini untuk mengakses MariaDB server:

 # mysql -u root -p

That’s all.
