Error: Package: percona-xtrabackup-24-2.4.8-1.el6.x86_64 (percona-release-x86_64) Requires: libev.so.4()(64bit)

I was trying to install xtrabackup version 2.4.8 on my centos 6.4 which resulted with following errors,

[root@dbtest3 ~]# yum install percona-xtrabackup-24.x86_64

          Requires: libev.so.4()(64bit)
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

From the above error it is clear that i am missing the following dependencies :-

rsync
libev

Which should be installed along with the xtrabackup installation but it didn’t so i decided to install the both and finally i should be able to install xtrabackup.

rsync was successfully installed,

But when i tried to install libev i was facing the below error,

[root@dbtest3 ~]# yum install libev
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* base: mirror.dhakacom.com
* extras: mirror.dhakacom.com
* updates: mirror.dhakacom.com
Setting up Install Process
No package libev available.
Error: Nothing to do
[root@dbtest3 ~]#

In order to fix this issue i need to install an external repo such as EPEL which will allow me to install libev.

After successful installation of  EPEL,  i tried to install libev but faced below issue,

[root@dbtest3 ~]# yum install libev
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again
To fix the above issue you need to edit your epel repo and edit it by changing https to hhtp on mirrorlist

vi /etc/yum.repos.d/epel.repo

In the below change https to http on entry mirrorlist

Before :-
[epel]
name=Extra Packages for Enterprise Linux 6 - $basearch
#baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch
failovermethod=priority
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

After :-
[epel]
name=Extra Packages for Enterprise Linux 6 - $basearch
#baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
mirrorlist=http://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch
failovermethod=priority
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

After changing the above i was able to install libev,

[root@dbtest3 ~]# rpm -qa | grep libev
libev-4.03-3.el6.x86_64

Screen Shot 2017-07-27 at 11.43.35 AM.png

Finally after installing libev i was able to install xtrabackup successfully.

[root@dbtest3 ~]# rpm -qa | grep xtrabackup
percona-xtrabackup-24-2.4.8-1.el6.x86_64
[root@dbtest3 ~]#
