MySQL Full script upgrade, support multiple hosts, multiple databases

This foot is an upgrade to the script written in the morning (previous address http://www.sql8.net/a/course/shujuku/Mysql/2014/0815/30340.html)

For colleagues multiple databases and data accounts, passwords, the host may not be the same situation overwrite

After rewriting, two scripts are required to complete the collaboration.

One for batch execution script batch.sh

Two for data backup script databak.sh

Batch execution Script batch.sh**************************************

SH databak.sh 192.168.1.1 database1 bak1 12322
SH databak.sh localhost database2,database3,database4 bak 123333

*********************************************************************************************

Data backup Script databak.sh**************************************

#!/bin/bash
#mysql全备脚本, this script can back up multiple databases,
#为每个数据建立单独的文件夹进行备份
#对于不同帐号, different libraries, not hosts
#调用参数格式 host Database account password
#调用方法
#同一帐号多个数据库可以用, separating
#sh databak.sh host Database account password
#sh databak.sh localhost youoil bak 123
