Installing Percona XtraBackup from Percona ​​yum​​ repository

  2. 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:


    ... 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 2.3.5-1.el5 percona-release-x86_64 percona-xtrabackup-test.x86_64 2.3.5-1.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:

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.

$ 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
