Mysql has the following types of logs:
Error log:-log-err
Query log:-log
Slow log:-log-slow-queries
Update log:-log-update
Binary log:-log-bin
In the mysql installation directory, open my.ini, add the above parameters, save and restart the mysql service.
For example:
# Enter a name for the error log file. Otherwise a default name will be used.
Log-error=err.log
# Enter a name for the query log file. Otherwise a default name will be used.
# log=
# Enter a name for the slow query log file. Otherwise a default name will be used.
# log-slow-queries=
# Enter a name for the update log file. Otherwise a default name will be used.
# log-update=
# Enter a name for the binary log. Otherwise a default name will be used.
# log-bin=
Only the error log is opened above. If you want to open other logs, remove the previous "#".
Long_query_time = 1-- refers to how long the sql will be executed by log, which is 1 second.
Log-slow-queries=slowqueris.log-returns the query to slower statements for recording
Log-queries-not-using-indexes = nouseindex.log-literally, query that does not use an index under log
Log=mylog.log-record all execution statements
Log-error=log-error.log
Log=log-query.log
