安装percona xtrabackup

环境：centos6

简介：

innobackupex 和xtrabackup

innobackupex is the symlink for xtrabackup. innobackupex still supports all features and syntax as 2.2 version did, 

but is now deprecated and will be removed in next major release.

After Percona XtraBackup 2.3 release the recommend way to take the backup is using the xtrabackup script. 

innobackupex实际上是xtrabackup的软链接，2.3版本开始，percona建议弃用innobackupex进行备份。

ls -l /usr/bin/innobackupex 

lrwxrwxrwx. 1 root root 10 Sep 13 09:41 /usr/bin/innobackupex -> xtrabackup

------------------------------

安装：

1. Install the Percona repository

$ wget http://www.percona.com/downloads/percona-release/redhat/0.1-6/\

percona-release-0.1-6.noarch.rpm

$ rpm -ivH percona-release-0.1-6.noarch.rpm

此时在目录/etc/yum.repos.d会生成两个文件

percona-release.repo

percona.repo

其中percona-release.repo是percona提供的预览版本的工具库。

可以把这个[percona-testing-$basearch]和[percona-testing-noarch]中的enabled改为1

2. Testing the repository

yum list | grep xtrabackup |grep percona

如果看到类似的输出，就说明可以安装了

yum install percona-xtrabackup-24

# rpm -qa |grep -i xtrabackup

percona-xtrabackup-24-2.4.12-1.el6.x86_64

# rpm -ql percona-xtrabackup-24-2.4.12-1.el6.x86_64

/usr/bin/innobackupex

/usr/bin/xbcloud

/usr/bin/xbcloud_osenv

/usr/bin/xbcrypt

/usr/bin/xbstream

/usr/bin/xtrabackup

/usr/lib64/xtrabackup/plugin/keyring_file.so

/usr/lib64/xtrabackup/plugin/keyring_vault.so

/usr/share/doc/percona-xtrabackup-24-2.4.12

------------------------------

排错：

yum list | grep percona

[Errno 14] problem making ssl connection

解决：

cd /etc/yum.repos.d

mv epel.repo epel.repo.bk

mv percona-release.repo percona-release.repo.bk

mv percona.repo percona.repo.bk

yum install ca-certificates

mv /etc/yum.repos.d/epel.repo.bk /etc/yum.repos.d/epel.repo

mv percona-release.repo.bk percona-release.repo

mv percona.repo.bk percona.repo

然后就可以正常安装了
