Question

Ho un problema con MySQL. Quando sto cercando di avviarlo, che mi dà un messaggio di errore, che è

Queste istruzioni hanno lavorato per me in una nuova installazione di MariaDB in Arch Linux:

systemctl stop mariadb 
rm -R /var/lib/mysql/* 
mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql 
systemctl start mariadb
