MySQL (MariaDB) Not Starting [closed]

I am running Arch Linux 4.8.4-1 on a 64bit installation. I installed MariaDB via pacman. When I try to start it with systemctl start mysqld, it gives me

Job for mariadb.service failed because the control process exited with error code.
See "systemctl status mariadb.service" and "journalctl -xe" for details.

The output of systemctl status mariadb.service is

● mariadb.service - MariaDB database server

If I need to post anything else, let me know...

UPDATE: After trying Jérémy Munoz's comment, mysql still doesn't start, but I get a different systemctl status mariadb.service

UPDATE: After running mysql_install_db, I get this error:

FATAL ERROR: Could not find ./bin/my_print_defaults

If you compiled from source, you need to either run 'make install' to
copy the software into the correct location ready for operation.
If you don't want to do a full install, you can use the --srcddir
option to only install the mysql database and privilege tables

If you are using a binary release, you must either be at the top
level of the extracted archive, or pass the --basedir option
pointing to that location.

The latest information about mysql_install_db is available at
https://mariadb.com/kb/en/installing-system-tables-mysql_install_db

/etc/mysql/my.cnf

If you haven't any real data in your database then clear all in /var/lib/mysql.

After that try again to run command mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql to initialize database directory.

You need to run mysql_install_db to initialize MySQL data directory.

cd /var/lib/mysql
ls
rm -r *
mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql
systemctl start mysqld
systemctl start mysql.service
systemctl start mariadb
mysql

Then it works just fine

Faced same problem. This got resolved after following below steps:

Uninstalled the mariadb maridb-server packages
Removed the directory /var/lib/mysql.
Reinstalled the Mariadb, Mariadb-server packages.
systemct start mariadb; systemctl enable mariadb

(problem solved).

I had same problem on Ubuntu 18.04m packages registered seem unable to start or else...

I resolved by adding correct package list and signature from the this site.

sudo apt-get install software-properties-common
sudo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xF1656F24C74CD1D8
sudo add-apt-repository 'deb [arch=amd64,arm64,ppc64el] http://mariadb.mirrors.ovh.net/MariaDB/repo/10.3/ubuntu bionic main'
sudo apt update
sudo apt install mariadb-server

et voila..
