edit /etc/my.cnf

using

# vi /etc/my.cnf

Then add

log-slow-queries
long_query_time = 5

Long_query_time is the number of seconds for a query to be considered long enough to log. The log will be created with detailed information about the queries that are slower than 5 seconds (in this case) for MySQL.

The default location of this log is

/var/lib/mysql/server-slow.log
