Выйти из mysql
exit
Устанавливаем Workbench на Ubuntu
sudo apt install snapdsnap install mysql-workbench-community
или
sudo apt install mysql-workbench-community
Запускаем Workbench и правым кликом мыши переходим в Edit Connection
Открывается Manage Server Connection — > Connection -> Parametrs и устанавливаем hostname — localhost, port — 3306, user — root и вводим пароль.
Если появится ошибка на Ubuntu при запуске Workbench
Cannot Connect to Database Server
Your connection attempt failed for user ’root’ to the MySQL server at localhost:3306:
An AppArmor policy prevents this sender from sending this message to this recipient; type=»method_call», sender=»:1.152″ (uid=1000 pid=8985 comm=7snap/mysql-workbench-community/10/usr/bin/- mysql-w» label=»snap.mysql-workbench-community.mysql-workbench- community (enforce)») interface=»org.freedesktop.Secret.Service» member=»OpenSession» error name=»(unset)» requested_reply=»0″ destination=»:1.17″ (uid=1000 pid=1753 comm=7usr/bin/gnome- keyring-daemon -daemonize -login» label=»unconfined”)
Please:
Check that MySQL is running on address localhost
Check that MySQL is reachable on port 3306 (note: 3306 is the default, but this can be changed)
Check the user root has rights to connect to localhost from your address (MySQL rights define what clients can connect to the server and from which machines)
Make sure you are both providing a password if needed and using the correct password for localhost connecting from the host address you’re connecting from
или
Store Password

Устанавливаем на Ubuntu
sudo snap connect mysql-workbench-community:password-manager-service :password-manager-service
И ошибки должны пропасть.
Дополнительные команды, если требуются
snap connect mysql-workbench-community:password-manager-service
— snap connect mysql-workbench-community:ssh-keys
— snap connect mysql-workbench-community:cups-control
Переходим в Workbench и запускаем Local instance и вводим пароль, после чего открывается графический интерфейс базы данных
