CentOS 6.6 installation Xtrabackup RPM prompts that libev. so.4 (), xtrabackuplibev is missing

The following error message is reported when installing the percona-xtrabackup-2.3.4 in CentOS Release 6.6

Rpm-ivh percona-xtrabackup-2.3.4-1.el6.x86_64.rpm

The following error occurs in percona-xtrabackup (2.3.2-1. For details, refer to Bug #1526636-by mentioning hard requirement on libev package in rpm distros.

In fact, percona-xtrabackup depends on libev. so.4 () (64bit) package, which can only be from EPEL source (Extra Packages for Enterprise Linux, an additional package for Enterprise Linux is a software warehouse project maintained by the Fedora team, provide a software package that is not provided by default for RHEL/CentOS) installation, so you only need to install this package to solve the problem.

When installing the latest release of percona-xtrabackup (2.3.2-1) from the percona repo, it encounters a missing dependency for libev. so.

Error: Package: percona-xtrabackup-2.3.2-1.el6.x86_64 (percona)

Requires: libev. so.4 () (64bit)

This can be resolved by installing an external repo such as EPEL, but probably shocould be stored in the percona repo. alternatively switching to AnyEvent (if EV is not a hard requirement) wocould allow for EV or the internal loop if EV is not installed on a system.

Have not tested this issue with other releases of CentOS.
