Sometimes, you want to use a new repository.  Like when installing [[Jenkins]] (although it's found in the regular repos, so maybe this isn't the best example for needing a separate repo)
 
 
from http://pkg.jenkins-ci.org/redhat/
 
<source lang="bash">
 
sudo wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat/jenkins.repo
 
sudo rpm --import http://pkg.jenkins-ci.org/redhat/jenkins-ci.org.key
 
sudo yum install jenkins
 
</source>
 
 
;How do I find what repository provides a given package?:
 
: You use <code>repoquery</code>
 
 
For example, you have a package called <code>glibc-devel-2.12-1.107.el6_4.4.i686</code>
 
<source lang="bash">
 
repoquery -i glibc-devel-2.12-1.107.el6_4.4.i686
 
</source>
 
<pre>
 
Name        : glibc-devel
 
Version    : 2.12
 
Release    : 1.107.el6_4.4
 
Architecture: i686
 
Size        : 976153
 
Packager    : Red Hat, Inc. <http://bugzilla.redhat.com/bugzilla>
 
Group      : Development/Libraries
 
URL        : http://sources.redhat.com/glibc/
 
Repository  : rhel-6-workstation-rpms
 
Summary    : Object files for development using standard C libraries.
 
Source      : glibc-2.12-1.107.el6_4.4.src.rpm
 
Description :
 
The glibc-devel package contains the object files necessary
 
for developing programs which use the standard C libraries (which are
 
used by nearly all programs).  If you are developing programs which
 
will use the standard C libraries, your system needs to have these
 
standard object files available in order to create the
 
executables.
 
 
Install glibc-devel if you are going to develop programs which will
 
use the standard C libraries.
 
</pre>
 
 
List the files of a package with <code>repoquery</code>
 
<source lang="bash">sudo repoquery -q -l mysql-connector-java</source>
 
If you don't have the repoquery command, install yum-utils first.
