怎样分割 MYSQLDump 全库备份成单独的文件
|
这篇文章将为大家详细讲解有关如何将MYSQLDUMP全库备份分为单库文件，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。 有时候我们备份是做的全库的备份，但是在恢复的时候却需要单库的文件，如果需要的库很小，我们把全库备份恢复回去然后导出想要的库的文件势必非常慢和耗时，这个时候如果 能够拆分文件为单库就好了，所以做了如下一个工具 工具叫做mysplit 可以查看备份出来每个库的大小和分割文件。 下载百度云盘： http://pan.baidu.com/s/1mhfl6R2 下载后传入到LINUX系统 chmod 755 mysplit1.2 就可以用了帮助如下： /***************************************************** Copyright by GaoPeng .All rights reserved.Version 1.2 This tool is uesd to split more than one database dump to split to single database file and show every datab ase dump size.
