MySQL导入sql脚本错误:2006 - MySQL server has gone away

MySQL导入sql脚本错误:2006 - MySQL server has gone away

到如一些小脚本很少报错,但最近导入一个10+M的SQL脚本,却重复报错:

Error occured at:2014-03-24 11:42:24
Line no.:85
Error Code: 2006 - MySQL server has gone away

最终找到原因,原来是MySQL导入大批量数据的时候超出了默认允许最大的数据包所以就提示2006 - MySQL server has gone away

于是找到my.cnf,在[mysqld]加入:

 

max_allowed_packet=300M

wait_timeout=200000

interactive_timeout = 200000

 

意思是最大允许数据包300M,等待超时/活动失效时常200000秒,重启MySQL

[root@lizhong 20140323]# /etc/init.d/mysqld restart

Shutting down MySQL.... SUCCESS! 

Starting MySQL. SUCCESS!

再重新导入,一切正常!
