wget  https://www.percona.com/downloads/XtraBackup/Percona-XtraBackup-2.4.9/binary/debian/trusty/x86_64/Percona-XtraBackup-2.4.9-ra467167cdd4-trusty-x86_64-bundle.tar

tar -xvf  Percona-XtraBackup-2.4.9-ra467167cdd4-trusty-x86_64-bundle.tar

dpkg -i *.deb

apt-get install  -f

安装完成能看到系统有innobackupex 命令即可

自动每天全备脚本：all_backup.sh

#!/bin/bash
basedir="/data/innobackupex/$(date "+%y%m%d")" ;
sudo innobackupex --defaults-file=/etc/mysql/my.cnf --user=root --password='xxxx'  $basedir   &>> "/data/innobackupex/$(date "+%y%m%d").log"

自动每小时增备脚本：add_backup.sh

#!/bin/bash
basedir="/data/innobackupex/$(date "+%y%m%d")" ;
add_basedir="$basedir/`ls $basedir|tail -n1`";
sudo innobackupex  --defaults-file=/etc/mysql/my.cnf  --user=root --password='xxxxx' --incremental-basedir="$add_basedir" --incremental $basedir  &>> "$basedir/$(date "+%y%m%d%H%M").log" ;

5 0 * * * sudo /bin/bash /data/innobackupex/all_backup.sh     #每天零点5分全备
55 * * * * sudo /bin/bash /data/innobackupex/add_backup.sh    #每个小时的55分进行一次增备

后续还需要一些自动清理空间的脚本
