Yellow Dog Updater Modified (YUM)

Yellow Dog Updater Modified (YUM) in 2007 we created a repository and also configured access to repositories in RHEL5. In YUM – I’ll configure YUM by using its main configuration file, yum.conf, which resides in ‘/etc’ in LINUX.

For any yum newbie’s like ME. , a quick definition and a look at history. YUM is a package manager (an installer and remover) for RPM systems. It is tailor made to update groups of machines without having to update each specific RPM. The software locates and obtains the correct RPM packages from repositories, freeing you from having to manually find and install new applications and/or updates. The beauty of YUM is in its simplicity to use. You can use a single command to update all system software with backward compatibility of RPM taken care of .. .

Some tips :

yum list “*ssh*”                 # lists packages that have “ssh” in the name
chkconfig yum on            # make yum update all programs every night
yum remove up2date    # remove a program, dependencies handled
yum -y install radius       # -y answers “yes” to all questions
