6G数据库的导入 报各种错误的解决办法
今天看到一高人的mysql数据库达到了6G左右，导入都是个问题，上传也挺麻烦的，这里特分享下，方便需要的朋友
工具选择一。sqlyog 这个工具还是很强大的，但是面对5个G的数据库来说，也只能罢工了，简单说，本机导入可以，从本机导入服务器不行。
二。phpadmin 自带的这个挺人家说还行，但是最后没用过，原因是看不见，因为最多50M，虽然修改配置文件可以上传但是5个G还是算了吧，没那个信心。
三。还有一个是一个PHP脚本。好像是德国人写的。这个东西，也是导入数据的，怎嘛说呢，本人是没试验成功。但是网上叫好一片，我是5G数据没点成功，这是折腾了第二天了。
四。数据库分割导入这个我也用到了，每个分割100M，汗一下。不能再小了。。。分割出60多个SQL，还是会报各种错误。这个工具也失败了。如果你想用，去网上找找吧mysql分割
下面的图片就是导入成功后的图片了，
GZ压缩式1.3G解压后变成4.52G。导入到数据库，就变成6.6G了。。。。。
最后还是用命令导进去的
mysql -uroot -p shujukuming
再说下错误吧
简单的说就是各种错误都能遇到
错误1
ERROR 5 (HY000) at line 318: Out of memory (Needed 1681784 bytes)
这个错误能报很多 是使用 -f 报出来的，大致意思是内存不足，
解决办法 ：mysql -uroot -p shujukuming -f
错误2
ERROR 1062 (23000) at line 30: Duplicate entry '1' for key 'PRIMARY'
这个错误是键值错误的意思
解决办法：网上说是要清空数据表数据，可是在用数据分区的时候主键和分区时不能同时使用，把主键在更改下就行
错误3
mysql error nr.2006-mysql server has gone away
这个错误是 上传限制的问题需要修改配置文件
配置文件在 linx叫 my.conf 在windows叫my.ini
这里面的东西修改要小心了乱改是不行的。
简单的就是修改几个配置就行了
max_allowed_packet=166666m 这个是限制文件大小的由于要上传6个G所以改成1111111M 额应该够了吧
wait_timeout=288000000 等待超时。。看事改吧，我在后面加了好几个0.。。
interactive_timeout= 288000000运行超时。。。。看事改吧，我在后面加了好几个0.。。
除了几个就不要修改其他的配置文件了，注意重启下服务器
错误4
这个是个很低级的错误
mysql 版本不对 现在流行的都是5.0+
注意高版本不能导入低的版本，5.5+是不能导入到5.0+的有些查询语句不支持。

以上就是本人遇到的各种问题，如有其它问题请多多指教，毕竟6个G的文件啥sql也打不开
