slave節(jié)點完成基礎環(huán)境的配置：創(chuàng)建好mysql用戶，裝好相同版本的mysql軟件，xtrabackup軟件包，，創(chuàng)建好目錄，配置好腳本

1、創(chuàng)建完整備份：master
[mysql@master1 backup]$ innobackupex --defaults-file=/data/mysqldata/3306/my.cnf --user=xtrabk --password='onlybackup' /backup/backup_full/

2、復制和準備備份集
[mysql@master1 backup_full]$ scp -r /backup/backup_full/2015-05-21_01-31-19/* 10.1.1.18:/data/mysqldata/3307
[mysql@master2 3307]$ innobackupex --apply-log /data/mysqldata/3307/data/
