  • Are you sure that's MySQL? `10.4.14` sounds like a MariaDB version. – Bill Karwin Sep 10 '21 at 18:35

    If `mysqld` is not running, you can back up a database any way you want, e.g. with `tar` or `zip` or whatever. I don't know why `mysqld` isn't starting for you. The log you show doesn't include any errors or warnings. – Bill Karwin Sep 10 '21 at 18:37
  • i copy ibdata1 file and database related folder to new xampp folder. but i did not work – Hardeep Singh Sep 10 '21 at 18:52
  • This doesn't feel like a code-problem per se. Have you tried https://dba.stackexchange.com – Marc L. Sep 10 '21 at 19:03
  • this looks like your server has started normally, no need for dba – nbk Sep 10 '21 at 19:06
