#Centos 6.6 final 安装 xtrabackup 2.2.12 小记

#（1）下载xtrabackup

wget  https://www.percona.com/downloads/XtraBackup/Percona-XtraBackup-2.2.12/binary/redhat/6/x86_64/percona-xtrabackup-2.2.12-1.el6.x86_64.rpm

（2）rpm安装xtrabackup

rpm -ivh percona-xtrabackup-2.2.12-1.el6.x86_64.rpm

失败

原因：需要先安装 perl

（3）安装perl

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

失败 

原因：yum perl 默认是安装 mysql-libs-5.1.73-5.el6_6.x86_64 和当前已安装的 server 的 MySQL-server-5.6.25-1.el6.x86_64 有冲突，因此需要先安装shared版本。

（4）下载安装mysql-shared

wget  http://cdn.mysql.com/archives/mysql-5.6/MySQL-shared-5.6.15-1.el6.x86_64.rpm

rpm -ih MySQL-shared-5.6.15-1.el6.x86_64.rpm

（5）下载安装 mysql-shared-compat

wget  http://cdn.mysql.com/archives/mysql-5.6/MySQL-shared-compat-5.6.15-1.el6.x86_64.rpm 

rpm -ih MySQL-shared-compat-5.6.15-1.el6.x86_64.rpm

（6）重新安装perl

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

成功

（7）重新安装 xtrabackup

rpm -ivh percona-xtrabackup-2.2.12-1.el6.x86_64.rpm

成功
