Mariadb is officially Database implementation of MySQL as many other Linux distributions. Today we will see HowTo Install and configure Mariadb Server on archlinux and see how we could simple Administrative task on same.

SetUP

For our setup we are using latest archlinux as of now Nov 2017.

After installation of, we could verify this through Query pacman.

[root@archlinux ~]# pacman -Q mariadb mariadb-clients
mariadb 10.1.29-1
mariadb-clients 10.1.29-1

Start Mariadb Service

Before strat of service, run below command 

[root@archlinux ~]#  mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql
Installing MariaDB/MySQL system tables in '/var/lib/mysql' ...

Now start Mariadb service.

[root@archlinux ~]# systemctl start mariadb

Now should follow secure like in below mentioned output.

[root@archlinux ~]# /usr/bin/mysql_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
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!

So now Mariadb is installed and up and running on Archlinux machine as required . Let’s make it available on boot time.


[root@archlinux ~]# systemctl enable mariadb
Created symlink /etc/systemd/system/multi-user.target.wants/mariadb.service -> /usr/lib/systemd/system/mariadb.service.

We can login locally on MySQL to work on its SQL console.

[root@archlinux ~]# mysql -u root -p
