CentoS 6.X安裝xtrabackup 2.2.13
作為一線運維或者DBA對數據備份絕對不會陌生，mysqldump、xtrabackup等常見備份姿勢更是非常熟悉，還有很多商業備份工具以及其他的開源備份工具，所謂的冷備、熱備、增量備份什麽的，各種名詞直接晃悠的你頭疼。接下來跟著我繼續踩一遍軟件安裝的坑吧。
操作系統：CentoS 6.7
Xtrabackup版本：2.2.13
MySQL版本：5.6.30
官網文檔：https://www.percona.com/doc/percona-xtrabackup/2.2/installation/yum_repo.html
常見的安裝方式有源碼包和yum以及RPM等方式，源碼編譯什麽比較麻煩，rpm包安裝可能會出現依賴性的問題，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
根據文檔配置yum源，然後開始安裝軟件，下載什麽很慢，並且出現以下報錯，於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: percona-xtrabackup-22-2.2.13-1.el6.x86_64: failure: percona-xtrabackup-22-2.2.13-1.el6.x86_64.rpm from percona-release-x86_64: [Errno 256] No more mirrors to try.
4、使用wget下載文件 用rpm安裝
wget
[email protected] ~]# 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 error: Failed dependencies: perl(DBD::mysql) is needed by percona-xtrabackup-22-2.2.13-1.el6.x86_64 perl(Time::HiRes) is needed by percona-xtrabackup-22-2.2.13-1.el6.x86_64

在rpm包安裝的時候出現依賴報錯，我們檢查了yum安裝的時候出現的依賴軟件包，根據提示安裝相關的軟件即可，例如：
yum install -y perl-DBD-MySQL perl-Time-HiRes
再執行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！
