代码如下:
show variables like '%timeout%';
show variables like '%packet%';
set global max_allowed_packet=99328000;
set global wait_timeout=2880000;
set global interactive_timeout=2880000;
-- wait_timeout=2880000
-- interactive_timeout=2880000
-- max_allowed_packet=100M
PS:如果是在服务器上,要记得恢复后这几个参数要调回去,不然性能会下降的,具体这几个参数功能,大家自己找找吧.
