Install the package
YUM installs the package if it is not already present and updates it with the latest version available from repo if the package already installed and present.
#yum install <package>
Check which package (available from repo) provides the binary file/command.
#yum provides <binary file/command>
Often we want to see what are the list of versions available for same package so that we install a specific version. From https://unix.stackexchange.com/questions/151689/how-can-i-instruct-yum-to-install-a-specific-version-of-package-x
$ yum --showduplicates list httpd | expand Loaded plugins: fastestmirror, langpacks, refresh-packagekit Loading mirror speeds from cached hostfile * fedora: mirror.steadfast.net * rpmfusion-free: csc.mcs.sdsmt.edu * rpmfusion-free-updates: csc.mcs.sdsmt.edu * rpmfusion-nonfree: csc.mcs.sdsmt.edu * rpmfusion-nonfree-updates: csc.mcs.sdsmt.edu * updates: mirror.steadfast.net Available Packages httpd.x86_64 2.4.6-6.fc20 fedora httpd.x86_64 2.4.10-1.fc20 updates
As far as installing a particular version? You can append the version info to the name of the package like so:
$ sudo yum install <package name>-<version info>
For example in this case if I wanted to install the older version, 2.4.6-6 I’d do the following:
$ sudo yum install httpd-2.4.6-6
You can also include the release info when specifying a package. In this case since I’m dealing with Fedora 20 (F20) the release info would be “fc20”, and the architecture info too.
$ sudo yum install httpd-2.4.6-6.fc20 $ sudo yum install httpd-2.4.6-6.fc20.x86_64
Individual commands for RPM to install and update.
#rpm -ivh <package> #rpm -Uvh <package>
Note: Always install the new kernel instead of updating.
$ yum --downloadonly <package> -or- $ yumdownloader <package>
$ sudo yum localinstall <path to rpm>
$ yumdownloader --resolve <package>
$ yumdownloader --resolve vim-X11 Loaded plugins: langpacks, presto, refresh-packagekit Adding en_US to language list --> Running transaction check ---> Package vim-X11.x86_64 2:7.3.315-1.fc14 set to be reinstalled --> Finished Dependency Resolution vim-X11-7.3.315-1.fc14.x86_64.rpm
Remove the package
#yum remove <package> #rpm -e <package>
Packages update history
History of packages install/update/erase
#yum history list #yum history list all
If we want to see what are the packages changed in that transaction
#yum history info <id>
History of single package since the installation
#yum history package <package>
On old RHEL there is no history option for yum command. If we want to see the package versions changed with the date and time run the rpm
#rpm -qa --last
