Har du tappat bort din l\u00f6senordslista igen? Huvudanv\u00e4ndarnas inloggningsuppgifter \u00e4r l\u00e4tta att f\u00f6rlora och lagras inte i sj\u00e4lva systemet.
\nDet \u00e4r s\u00e4kert l\u00e4ttare h\u00e4r med databaser som anv\u00e4nds av Inneh\u00e5ll<\/a> hanteringssystem lagras l\u00f6senordet i klartext i respektive konfigurationsfiler. Detta \u00e4r inte fallet f\u00f6r huvudanv\u00e4ndaren av databasservern.
\nSom regel \u00e4r anv\u00e4ndarnamnet root. P\u00e5 Plesk<\/a> Anv\u00e4ndarnamnet \"admin\" anv\u00e4nds dock f\u00f6r installationer. L\u00f6senordet f\u00f6r en Plesk-server kan enkelt l\u00e4sas fr\u00e5n .psa\/shadow-filen. Till exempel med kommandot:<\/p>\n

mysql<\/a> -uadmin -p`cat \/etc\/psa\/.psa.shadow<\/code><\/p>\n

Om du beh\u00f6ver \u00e5terst\u00e4lla l\u00f6senordet helt och h\u00e5llet f\u00f6ljer du de h\u00e4r stegen.<\/p>\n

Stoppa databasservern. T.ex. under Centos7 med MariaDB med <\/p>\n

systemctl stoppa mariadb.service<\/code><\/p>\n

Om du anv\u00e4nder en annan databasserver kan detta ocks\u00e5 g\u00f6ras med<\/p>\n

\/etc\/init.d\/mysql stop<\/code><\/p>\n

\u00c4ndring av l\u00f6senordet f\u00f6r MariaDB\/MySQL-roten<\/h2>\n

Nu startar vi databasservern utan begr\u00e4nsningar och r\u00e4ttighetshantering, s\u00e5 att den kan administreras utan l\u00f6senord. F\u00f6r att g\u00f6ra detta anv\u00e4nder vi alternativet -skip-grant-tables, som tar bort begr\u00e4nsningarna, och -skip-networking, s\u00e5 att ingen extern \u00e5tkomst kan ske under inst\u00e4llningen.<\/p>\n

mysqld_safe --skip-grant-tables --skip-networking &<\/code><\/p>\n

Nu kan du enkelt \u00e4ndra MySQL-l\u00f6senordet.<\/p>\n

mysql -u root
\nmysql> use mysql;
\nmysql> update user set password=PASSWORD(\"the_desired_password\") where User='root';
\nmysql> flush privilegier;
\nmysql> avsluta<\/code><\/p>\n

Nu \u00e4r l\u00f6senordet \u00e4ndrat och databasservern kan avslutas.<\/p>\n

mysqladmin avst\u00e4ngning<\/code><\/p>\n

S\u00e5 att den sedan kan startas normalt.<\/p>\n

systemctl start mariadb.service<\/code><\/p>\n
