Database Error 90003 Eve-ng [FAST]

EVE-NG relies on a local MySQL database to store everything: user credentials, lab topologies, node configurations, and permission settings. When the EVE-NG GUI (the web interface) cannot talk to the database backend, it throws this error.

If nothing else works:

mysql -u root eve_ng_prod Once inside the MySQL prompt ( mysql> ), run the repair command: Database Error 90003 Eve-ng

mysqld --datadir=/var/lib/mysql --skip-grant-tables --skip-networking & Next, log into MySQL manually (no password required due to skip-grant):

If you’ve spent any time building labs in EVE-NG, you know the feeling. You’re in the zone, dragging nodes onto the canvas, linking interfaces, and powering up routers. Suddenly, you hit a wall. EVE-NG relies on a local MySQL database to

systemctl stop mysql Now, run the MySQL safe recovery mode to force a repair of the EVE database:

It’s vague. It’s frustrating. And it usually brings your lab building session to a screeching halt. You’re in the zone, dragging nodes onto the

systemctl restart mysql Now, check if it is actually running:

repair table auth_behavior; repair table labs; repair table nodes; repair table users; exit; Finally, kill the safe mode process and restart normally:

systemctl status mysql If it shows active (running) , go back to your web browser, clear your cache, and refresh. If the error is gone—congratulations, you’re done. If MySQL fails to start or restarting didn't fix the GUI, the database tables are likely corrupted.
