MySQL (MariaDB) no se inicia

Estoy ejecutando Arch Linux 4.8.4-1 en una instalación de 64 bits. Instalé MariaDB a través de pacman. Cuando trato de comenzar systemctl start mysqld, me da

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

ACTUALIZACIÓN: después de ejecutar mysql_install_db, me sale este 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

Si no tiene datos reales en su base de datos, borre todo /var/lib/mysql.

Después de eso, intente nuevamente ejecutar el comando mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysqlpara inicializar el directorio de la base de datos.

Debe ejecutar mysql_install_dbpara inicializar el directorio de datos MySQL.

Tuve el mismo problema en Ubuntu 18.04m, los paquetes registrados parecen no poder iniciarse o de lo contrario ...

Resolví agregando la lista correcta de paquetes y la firma de este sitio .

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 ..

Frente El mismo problema se resolvió después de seguir los pasos a continuación Desinstalar los paquetes mariadb maridb-server Se eliminó el directorio / var / lib / mysql. Reinstaló los paquetes Mariadb, Mariadb-server. systemct start mariadb; systemctl enable mariadb (problema resuelto).
