工作中用到的Mysql单库备份Shell脚本,压缩备份,并在Crontab中添加计划任务,最多保存60天的备份

#!/bin/bash

. /etc/profile

USERNAME=zabbix
PASSWORD=xxxxx
DBHOST=127.0.0.1
DATABASES=zabbix
BACKUPDIR=/data/mysqlback/zabbix/fulldb
DATE=`date +%Y-%m-%d_%H:%M:%S`
rm -fv ${BACKUPDIR}/*$(date +%Y-%m-%d -d "60 days ago")*
BACKUPFILE=zabbix_full_db_${DATE}.sql.gz
/bin/mysqldump --single-transaction --user=${USERNAME} --password=${PASSWORD} --host=${DBHOST} --databases $DATABASES |gzip >${BACKUPDIR}/${BACKUPFILE}
#增加 --single-transaction 选项防止备份时锁表

  

crontab中添加:

00 03 * * * /bin/bash /opt/zabbix_mysql_bak.sh

  

解压缩:

gzip -d xx.sql.gz

  

安装percona-xtrbackup:

yum -y install http://www.percona.com/downloads/percona-release/redhat/0.1-4/percona-release-0.1-4.noarch.rpm

yum list|grep -i percona

yum -y install percona-xtrabackup-24.x86_64

  

只备份指定数据库并自动创建名为时间的文件夹

innobackupex --user=root --password=123456 --databases=blog /data/backups/full/

全备: 也会自动创建时间文件夹

innobackupex --user=root --password=123456 /data/backups/full/
