Question

我必须导入1g的sql数据，我将max_allowed_packet提升到1100M以确定。

所以我使用：

我的查询

mysql -u root -p -D mainbase < GeoPC_WO.sql

但1分钟后，它在此过程中停止，我收到此错误：

**ERROR 2013 (HY000) at line 23: Lost connection to MySQL server during query
**Lost connection to MySQL server during query****

Answer 1

您可能有一些大于最大大小的大型插入语句。检查/etc/mysql/my.cnf文件或其中的任何位置。不记得默认是什么 - 但将它设置为像下面这样大的东西可能会有所帮助。

这是一个选项

[mysqld]
max_allowed_packet = 16M

也许是另一种方式

[mysqldump]
max_allowed_packet = 16M

Answer 2

我有完全相同的问题。经过1小时的挣扎，我通过设置

解决了这个问题

net_write_timeout

更高的值（在我的情况下， 300 ）

Answer 3

在我的情况下，问题（“查询期间与MySQL服务器的连接失败”）是在损坏的转储文件或行为不当的硬盘驱动器中：

首先，我在主服务器上进行了转储，然后将该转储复制到复制服务器。但似乎复制服务器的硬盘存在问题，转储损坏，即主服务器上原始转储文件的MD5与复制服务器上转储副本的MD5不同。

Answer 4

你可以试试这个：

然后你应该编辑这个文件：

sudo /etc/init.d/mysql stop

将以下行添加到[mysqld]部分：

sudo vi /etc/mysql/my.cnf

最后：

innodb_force_recovery = 4

（innodb_force_recovery强制启动InnoDB存储引擎。值4表示您的数据文件可能已损坏。有关详细信息，请访问：http://dev.mysql.com/doc/refman/5.7/en/forcing-innodb-recovery.html）

问候。
