• wait_timeout – Time in seconds that the server waits for a connection to become active before closing it.
• interactive_timeout – Time in seconds that the server waits for an interactive connection.
• max_allowed_packet – Maximum size in bytes of a packet or a generated/intermediate string. Set as large as the largest BLOB, in multiples of 1024.

Example of my.cnf:

[mysqld]
# 8 hours
wait_timeout = 28800
# 8 hours
interactive_timeout = 28800
