1.执行批量的MYSQL语句，例如备份恢复的时候，时间过长。 
对应：修改my.cnf中的wait_timeout和interactive_timeout变量 
在一些不便修改的情形下，如租用的空间，可以采取sql语句修改，如何做呢？ 

解决办法

找到my.ini文件

添加一句max_allowed_packet=16M，如果不行将16M再加大

加大wait_timeout也可起一定作用

eg:

wait_timeout=2880000
interactive_timeout = 2880000
max_allowed_packet = 100M

应用时记住重启数据库哦～～

除此之外，可能还有一些别的buffer_size的变量会影响到，也值得注意 
例如 
read_buffer_size 
read_rnd_buffer_size
