Do you have a backup of your mysql database?

When you perform an update to a higher version of ISPConfig, ISPCOnfig creates a backup of it's database within the directory /tmp. If you're lucky you can find it there.

very bad for me that I don't backup mysql, and i don't find any mysql backup.

Can I revert it from configuration file?

Without the db you're lost.
A backup of datases are stored within /var/lib/mysql, please first if you have a backup of your ispconfig database there.
