Может ли кто-нибудь проверить эти проблемы и сказать мне, как их решить?
Возможно, некоторые значения слишком велики, но я не понимаю, какими они должны быть.
Я буду очень любезен за любую помощь.

-------- Recommendations --------------------------------------------------- ------------------------
General recommendations:
MySQL was started within the last 24 hours - recommendations may be inaccurate
Reduce your overall MySQL memory footprint for system stability
Dedicate this server to your database for highest performance.
Configure your accounts with ip or subnets only, then update your configuration with skip-name-resolve=1
Consider installing Sys schema from https://github.com/mysql/mysql-sys
Before changing innodb_log_file_size and/or innodb_log_files_in_group read this:
Variables to adjust:
*** MySQL's maximum memory usage is dangerously high ***
*** Add RAM before increasing MySQL buffer variables ***
query_cache_size (=0)
query_cache_type (=0)
innodb_file_per_table=ON
innodb_log_file_size should be (=256M) if possible, so InnoDB total log files size equals to 25% of buffer pool size.
