Bent u uw wachtwoordlijst weer kwijt? De inloggegevens van de hoofdgebruikers gaan snel verloren en worden niet op het systeem zelf opgeslagen.
\nHet is hier zeker gemakkelijker met databanken die gebruikt worden door Inhoud<\/a> Management Systemen, hier wordt het wachtwoord in platte tekst opgeslagen in de respectievelijke configuratiebestanden. Dit is niet het geval voor de hoofdgebruiker van de databaseserver.
\nGewoonlijk is de gebruikersnaam root. Op Plesk<\/a> installaties wordt de gebruikersnaam \"admin\" gebruikt. Het wachtwoord van een Plesk-server kan eenvoudig worden opgehaald uit het .psa\/shadow-bestand. Bijvoorbeeld: met het commando:<\/p>\n

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

Als u het wachtwoord volledig moet resetten, volgt u gewoon deze stappen.<\/p>\n

Verlaat de database server. Bijvoorbeeld onder Centos7 met MariaDB met <\/p>\n

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

Als u een andere database server gebruikt, kan dit ook gedaan worden met<\/p>\n

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

MariaDB \/ MySQL root Wachtwoord wijzigen<\/h2>\n

Nu starten we de database server zonder beperkingen en rechtenbeheer, zodat deze zonder wachtwoord kan worden beheerd. Hiervoor gebruiken we de optie -skip-grant-tables, die de beperkingen opheft, en -skip-networking, die externe toegang tijdens de installatie verhindert.<\/p>\n

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

Nu kunt u eenvoudig het MySQL-wachtwoord wijzigen.<\/p>\n

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

Nu wordt het wachtwoord gewijzigd en kan de databaseserver worden be\u00ebindigd.<\/p>\n

Mysqladmin-stillegging<\/code><\/p>\n

Zodat het dan normaal kan worden gestart.<\/p>\n

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