Unable to use the Percona repo at [www.percona.com](http://www.percona.com), I downloaded the PXC tarball Percona-XtraDB-Cluster-5.6.30-25.16-raa929cb-el7-x86\_64-bundle.tar, extracted the RPMs, individually installed client, galera-3, cluster shared, libev.so and xtrabackup. However, when I attempted to install the PXC cluster package, I got this error:

# yum install Percona-XtraDB-Cluster-server-56-5.6.30-25.16.1.el7.x86\_64.rpm

You could try using --skip-broken to work around the problem  
You could try running: rpm -Va --nofiles --nodigest

– but xtrabackup’s installed:

Installed Packages  
percona-xtrabackup-24.x86\_64 2.4.3-1.el7 @/percona-xtrabackup-24-2.4.3-1.el7.x86\_64

Note that Xtrabackup 2.4.3 is listed – I had installed 2.4.4, but when the PXC server install error occurred, attempted to rectify by dropping 2.4.4 and loading 2.4.3. It didn’t matter.

Has anyone else experienced this problem? Is there a workaround? I’d really like to get the s/w installed.

Solution to this problem involved setting non-existent environment variable correctly:

– then installing with yum from Percona repo per the documentation. Additionally, the package for libev needed to be installed prior for dependent package xtrabackup to be installed.
