1.安装依赖包
#yum -y install perl perl-devel libaio libaio-devel perl-Time-HiRes perl-DBD-MySQL
2. 安装percona-xtrabackup工具
# rpm -ivh percona-xtrabackup-24-2.4.7-1.el5.x86_64.rpm
提示缺少依赖：
warning: percona-xtrabackup-24-2.4.7-2.el6.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID cd2efd2a: NOKEY
error: Failed dependencies:
libev.so.4()(64bit) is needed by percona-xtrabackup-24-2.4.7-2.el6.x86_64
libnuma.so.1()(64bit) is needed by percona-xtrabackup-24-2.4.7-2.el6.x86_64
rsync is needed by percona-xtrabackup-24-2.4.7-2.el6.x86_64
安装libnuma依赖包命令：
3.查看安装目录
# rpm -ql percona-xtrabackup-24
/usr/bin/innobackupex
/usr/bin/xbcloud
/usr/bin/xbcloud_osenv
/usr/bin/xbcrypt
/usr/bin/xbstream
/usr/bin/xtrabackup
/usr/share/doc/percona-xtrabackup-24-2.4.7
/usr/share/doc/percona-xtrabackup-24-2.4.7/COPYING
/usr/share/man/man1/innobackupex.1.gz
/usr/share/man/man1/xbcrypt.1.gz
/usr/share/man/man1/xbstream.1.gz
/usr/share/man/man1/xtrabackup.1.gz
4.创建专用备份账户
mysql> create user backup@‘localhost‘ identified by ‘123456‘;
mysql> grant reload,PROCESS,lock tables,Replication client,super on *.* to backup@‘localhost‘;
5.全备、增备及恢复
全备：
#innobackupex --defaults-file=/etc/my.cnf --user=root --password=123456 /home/backup/full
全备恢复：
innobackupex --apply-log /home/backup/full/2017-06-14_21-26-56
innobackupex --copy-back /home/backup/full/2017-06-14_21-26-56
增备：
#innobackupex --defaults-file=/etc/my.cnf --user=root --password=123456 --incremental-basedir=/home/backup/full/2017-06-14_21-26-56 --incremental /home/backup/incremental
增备恢复：
第一步是在所有备份目录下重做已提交的日志：
innobackupex --apply-log --redo-only /home/backup/full/2017-06-14_21-26-56
innobackupex --apply-log --redo-only /home/backup/full/2017-06-14_21-26-56 --incremental-dir=/home/backup/incremental/2017-06-14_21-35-43
第二步回滚未完成的日志：
innobackupex --apply-log /home/backup/full/2017-06-14_21-26-56
第三步拷贝：
service mysql stop
执行copy-back之前需要清空mysql的data目录
innobackupex --copy-back /home/backup/full/2017-06-14_21-26-56
启动之前注意data目录的权限问题
service mysql start
mysql之 percona-xtrabackup 2.4.7安装（热备工具）
