常見的安裝方式有源碼包和yum以及RPM等方式，源碼編譯什么比較麻煩，rpm包安裝可能會出現(xiàn)依賴性的問題，本文中剛開始選擇了用yum的方式，

1、Install the Percona repository

yum install http://www.percona.com/downloads/percona-release/redhat/0.1-3/percona-release-0.1-3.noarch.rpm

2、Testing the repository

Make sure packages are now available from the repository, by executing the following command:

yum list | grep percona

You should see output similar to the following:

...
percona-xtrabackup-20.x86_64               2.0.8-587.rhel5             percona-release-x86_64
percona-xtrabackup-20-debuginfo.x86_64     2.0.8-587.rhel5             percona-release-x86_64
percona-xtrabackup-20-test.x86_64          2.0.8-587.rhel5             percona-release-x86_64
percona-xtrabackup-21.x86_64               2.1.9-746.rhel5             percona-release-x86_64
percona-xtrabackup-21-debuginfo.x86_64     2.1.9-746.rhel5             percona-release-x86_64
percona-xtrabackup-22.x86_64               2.2.13-1.el5                percona-release-x86_64
percona-xtrabackup-22-debuginfo.x86_64     2.2.13-1.el5                percona-release-x86_64
percona-xtrabackup-debuginfo.x86_64        2.3.2-1.el5                 percona-release-x86_64
percona-xtrabackup-test.x86_64             2.3.2-1.el5                 percona-release-x86_64
percona-xtrabackup-test-21.x86_64          2.1.9-746.rhel5             percona-release-x86_64
percona-xtrabackup-test-22.x86_64          2.2.13-1.el5                percona-release-x86_64

3、install the packages

You can now install Percona XtraBackup by running:

yum install percona-xtrabackup-22

  根據(jù)文檔配置yum源，然后開始安裝軟件，下載什么很慢，并且出現(xiàn)以下報錯，于是我們就采取下載文件的方式

Total size: 19 M
Total download size: 4.8 M
Is this ok [y/N]: y
Downloading Packages:
http://repo.percona.com/release/6/RPMS/x86_64/percona-xtrabackup-22-2.2.13-1.el6.x86_64.rpm: [Errno 14] PYCURL ERROR 18 - "transfer closed with 884350 bytes remaining to read"
Trying other mirror.


Error Downloading Packages:

4、使用wget下載文件 用rpm安裝

wget

root@username1-pc ~]# rpm  -ivh   percona-xtrabackup-22-2.2.13-1.el6.x86_64.rpm 
warning: percona-xtrabackup-22-2.2.13-1.el6.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID cd2efd2a: NOKEY

在rpm包安裝的時候出現(xiàn)依賴報錯，我們檢查了yum安裝的時候出現(xiàn)的依賴軟件包，根據(jù)提示安裝相關的軟件即可，例如：

yum  install -y  perl-DBD-MySQL  perl-Time-HiRes

再執(zhí)行rpm安裝命令

rpm  -ivh   percona-xtrabackup-22-2.2.13-1.el6.x86_64.rpm

安裝成功，就可以備份測試了！
