Yum
YUM, it's not just good eatin', it's also for updating your RedHat (or CentOS) packages. Here's a cheatsheet
What are the top 20 yummiest commands? http://www.tecmint.com/20-linux-yum-yellowdog-updater-modified-commands-for-package-mangement/
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/
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
- How do I find what repository provides a given package?
- You use
repoquery
For example, you have a package called glibc-devel-2.12-1.107.el6_4.4.i686
repoquery -i glibc-devel-2.12-1.107.el6_4.4.i686
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.
List the files of a package with repoquery
sudo repoquery -q -l mysql-connector-java
If you don't have the repoquery command, install yum-utils first.
EPEL[edit]
The Extra Packages for Enterprise Linux repository is usually something you want to add to all your RedHat/CentOS boxes. EPEL
