MySQL said: Documentation

#2006 - MySQL server has gone away

这个错误是什么意思？

我已在max_allowed_packet下将[mysqldump]配置为max_allowed_packet = 16M。

注意：在大约150个表中，只有22个表会随着此错误导入！

Answer 1

我认为您需要检查连接是否存在，如果不存在则重新建立连接。

此外，您尝试增加变量的超时，如下所示：

SET @@GLOBAL.wait_timeout=300;
SET @@LOCAL.wait_timeout=300;

或者您可以尝试在my.cnf文件中进一步将ma_allowed_packet增加到64M

max_allowed_packet=64M
wait_timeout= 6000
