背景：需要对Mysql做数据库备份，

解决方案方案：使用到Linux自带的crontab进行排成设定，通过自行编写的一个备份数据库的脚本把数据库进行备份，同时加入到crontab中就可以进行自动备份啦

 

 

 

 

 

 

 

 

 

 mysql_local_backup.sh

#!/bin/bash

DATE=`date +%Y-%m-%d`
OLDDATE=`date +%Y-%m-%d -d '-30 days'`

P=3307

#MYSQL=/usr/local/mysql/bin/mysql
#MYSQLDUMP=/usr/local/mysql/bin/mysqldump

BACKDIR=/data/mysql_local_backup
[ -d ${BACKDIR} ] || mkdir -p ${BACKDIR}

[ ! -d ${BACKDIR}/${OLDDATE} ] || rm -rf ${BACKDIR}/${OLDDATE}

MYSQLDUMP_LIST=`mysql -u root -u${USERNAME} -P${P} -h${H} -p${PASSWORD} -e "show databases"| grep -Evi "database|infor|perfor|sys|mysql"`

done
