Mysql recovers the solution of automatic disconnection of oversized files
Recently used backup file for mysqdump recovery, due to large data, it will automatically disconnect in 2 hours, so try the following settings to solve the problem
?
set global max_allowed_packet=100 000 000; set global net_buffer_length=100000; SET GLOBAL interactive_timeout=28800 000; SET GLOBAL wait_timeout=28800000
Explanation of the above statement:
max_allowed_packet=XXX Maximum size of buffer for client/server communication;
-net_buffer_length=XXX TCP/IP and socket communication buffer size, creating lines up to net_buffer_length
-interactive_timeout = 10; valid for subsequent interactive links;
-wait_timeout is valid for the current interactive link;
The above statement mainly solves: connection timeout, imported sql file is too large.
