MySQL (MariaDB) não está iniciando

10

Estou executando o Arch Linux 4.8.4-1 em uma instalação de 64 bits. Eu instalei o MariaDB via pacman . Quando eu tento iniciá-lo com systemctl start mysqld , isso me dá

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

A saída de systemctl status mariadb.service é

● mariadb.service - MariaDB database server

Se eu precisar postar mais alguma coisa, me avise ...

UPDATE: Depois de tentar o comentário de Jérémy Munoz, o mysql ainda não inicia, mas eu recebo um% diferente systemctl status mariadb.service

UPDATE: Depois de executar mysql_install_db , recebo este erro:

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.

Se você não tiver dados reais em seu banco de dados, limpe tudo em /var/lib/mysql .

Depois disso, tente executar novamente o comando mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql para inicializar o diretório do banco de dados.

Você precisa executar mysql_install_db para inicializar o diretório de dados do MySQL.
