This article will explain in detail how to divide MYSQLDUMP full database backup into single database files. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

Sometimes we do the backup of the whole library, but we need the files of a single library during the recovery. If the library we need is very small, it will be very slow and time-consuming for us to restore the backup of the full library and then export the files of the desired library.

It would be nice to be able to split the file into a single library, so I made the following tool

The tool called mysplit allows you to see the size and split files of each library that is backed up.

Download Baidu Cloud disk:

Http://pan.baidu.com/s/1mhfl6R2

After download, it is passed into the LINUX system.

Chmod 755 mysplit1.2

You can use the help as follows:

/ *

This tool is uesd to split more than one database dump

To split to single database file and show every datab

Ase dump size.

USEAGE:./mysplit-show/-split dumpfilename [charset]

-show to show every database dump size

-split TO split every database to single file

[charset] is optional default / * SET NAMES UTF8*/

Editer's qq:22389860,bugs report!

* * /

Use the instance to split the library:

[root@hadoop1 ~] # mysplit1.2-split log.log utf8

NOTE:if use-show Enter y follow hint is affect only-split

Will use charset utf8,please check!

Best way to find set names use Linux command:
