Linux下自动备份MySQL多个数据库

Linux下自动备份MySQL多个数据库

这里只提供脚本，和以前写的《Aix 5.3下自动备份Oracle多个实例》如出一辙，

如果要加入at或者crontab，请参考《CentOS5.4下自动备份MySQL数据库》这个大家再研究吧。

#MySQL User Information
USERNAME=数据库用户名(信息隐藏)
PASSWORD=数据库密码(信息隐藏)

#Back file
FILE_PREFIX=MySQL_

#FTP Server Information
FTP_SERV=FTP服务器(信息隐藏)
FTP_USER=FTP用户名(信息隐藏)
FTP_PASS=FTP密码(信息隐藏)
FTP_DIR=FTP目录(信息隐藏)

#Back directory
BACKUP_DIR=/opt/databack/MySQL

#MySQL directory
MYSQL_DIR=/usr/local/mysql/bin

#Date Format
DATE=`date +%Y%m%d`

#MySQL database
MYSQL1=第一个MySQL数据库名称(信息隐藏)
MYSQL2=第二个MySQL数据库名称(信息隐藏)
MYSQL3=第三个MySQL数据库名称(信息隐藏)

#Go to the backup directory

echo MySQL Database ${MYSQL1} ${DATE} backup file already exists.
else
