Connect to GreatSQL
After installing GreatSQL using the minimum binary package, check the initialization password through the log-error log and log in.
$ cat /var/log/|grep password
[Note] [MY-010454] [Server] A temporary password is generated for root@localhost: NrkNcJya<9f6
If you use the recommended GreatSQL, the error log path will change. Please use the following command to view the initialization password.
$ $ grep -i root /data/GreatSQL/
... A temporary password is generated for root@localhost: ji!pjndiw5sJ
Copy your password to log in to GreatSQL
