Installing Percona XtraBackup from Percona yum repository

1. Install the Percona repository

   You can install Percona yum repository by running the following command as a root user or with sudo:

   yum install http://www.percona.com/downloads/percona-release/redhat/0.1-6/percona-release-0.1-6.noarch.rpm
   

   You should see some output such as the following:

   Retrieving http://www.percona.com/downloads/percona-release/redhat/0.1-6/percona-release-0.1-6.noarch.rpm
   Preparing...                ########################################### [100%]
      1:percona-release        ########################################### [100%]
   

Note

RHEL/Centos 5 doesn’t support installing the packages directly from the remote location so you’ll need to download the package first and install it manually with rpm:

$ 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

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:

   ...

   ...
   

3. Install the packages

   You can now install Percona XtraBackup by running:

   yum install percona-xtrabackup-24
   

Warning

In order to sucessfully install Percona XtraBackup libev package will need to be installed first. libev package can be installed from the EPEL repositories.

Percona yum Testing Repository

Percona offers pre-release builds from our testing repository. To subscribe to the testing repository, you’ll need to enable the testing repository in /etc/yum.repos.d/percona-release.repo. To do so, set both percona-testing-$basearch and percona-testing-noarch to enabled = 1 (Note that there are 3 sections in this file: release, testing and experimental - in this case it is the second section that requires updating). NOTE: You’ll need to install the Percona repository first (ref above) if this hasn’t been done already.

Installing Percona XtraBackup using downloaded rpm packages

Download the packages of the desired series for your architecture from the download page. Following example will download Percona XtraBackup 2.4.4 release package for CentOS 7:

$ wget https://www.percona.com/downloads/XtraBackup/Percona-XtraBackup-2.4.4/binary/redhat/7/x86_64/percona-xtrabackup-24-2.4.4-1.el7.x86_64.rpm

Now you can install Percona XtraBackup by running:

$ yum localinstall percona-xtrabackup-24-2.4.4-1.el7.x86_64.rpm

Note

When installing packages manually like this, you’ll need to make sure to resolve all the dependencies and install missing packages yourself.
