準備：os是centos6.7,提前下載並上傳 percona-xtrabackup 安裝包，下載網址為： https://www.percona.com/downloads/XtraBackup/LATEST/
1.安裝依賴包
[[email protected] xtrabackup]# yum -y install perl perl-devel libaio libaio-devel perl-Time-HiRes perl-DBD-MySQL 
Dependency Installed:
  perl-DBI.x86_64 0:1.609-4.el6                                                    
Complete!
2. 安裝 percona-xtrabackup 工具
2.1 -- 發現缺包
[[email protected] ~]# rpm -ivh percona-xtrabackup-24-2.4.7-1.el5.x86_64.rpm
warning: percona-xtrabackup-24-2.4.7-1.el5.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID cd2efd2a: NOKEY
error: Failed dependencies:
libcurl.so.3()(64bit) is needed by percona-xtrabackup-24-2.4.7-1.el5.x86_64
libev.so.4()(64bit) is needed by percona-xtrabackup-24-2.4.7-1.el5.x86_64
2.2 -- 配置本地yum源後，用 yum 發現依然找不到包，搜尋後，網友解決方法是 單獨下載 libev-4.15-1.el6.rf.x86_64.rpm 包
2.3 -- 安裝 libev-4.15-1.el6.rf.x86_64.rpm 包，過了。

[email protected] ~]# rpm -ivh libev-4.15-1.el6.rf.x86_64.rpm
[[email protected] ~]#  rpm -ivh percona-xtrabackup-24-2.4.7-1.el5.x86_64.rpm
warning: percona-xtrabackup-24-2.4.7-1.el5.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID cd2efd2a: NOKEY
error: Failed dependencies:
libcurl.so.3()(64bit) is needed by percona-xtrabackup-24-2.4.7-1.el5.x86_64
2.4 -- libcurl.so.3()(64bit) is needed by percona-xtrabackup-24-2.4.7-1.el5.x86_64 ，依然解決不了，最後決定強行安裝。（這個問題卡了兩個小時，現在不能很好的解決，留到以後再看）

3. 測試，檢視 percona-xtrabackup  版本
[[email protected] ~]# innobackupex -v
innobackupex version 2.4.7 Linux (x86_64) (revision id: 6f7a799)
[[email protected] ~]# rpm -ql percona-xtrabackup-24
/usr/bin/innobackupex
/usr/bin/xbcloud
/usr/bin/xbcloud_osenv
/usr/bin/xbcrypt
/usr/bin/xbstream
/usr/bin/xtrabackup
說明：Xtrabackup有兩個主要的工具：xtrabackup、innobackupex
a、xtrabackup只能備份InnoDB和XtraDB兩種資料表，而不能備份MyISAM資料表
b、innobackupex是一個perl指令碼封裝了xtrabackup。支援同時備份InnoDB和MyISAM引擎的表。
4. 測試全備資料庫 
[[email protected] ~]# innobackupex --user=root --password=oracle --port=3606 --socket=/var/lib/mysql/mysql.sock  /xtrabackup/full/
170602 06:48:07 innobackupex: Starting the backup operation
IMPORTANT: Please check that the backup run completes successfully.
           At the end of a successful backup run innobackupex
           prints "completed OK!".

5. 檢查備份
[[email protected] ~]# ll  /xtrabackup/full/

說明：工具使用沒有問題，成功！
