Common commands for yum and rpm

Yum and rpm have many usage methods. I will only introduce what we may encounter frequently. If it is not commonly used, it will be pasted to the end of the article.

Installation of software packages

Use rpm-ivh package_name when installing the rpm installation package

Instance: rpm-ivh screen-4.0.3-19.el6.x86_64

Force installation: rpm-ivh package_name -- force (universal installation option) syntax format of the yum Installation Software: yum install package_name

Instance: yum install screen-4.0.3-19.el6.x86_64.rpm

Query a software package

The query of a software package can be used together with the installation and uninstallation of the software package. When we only know the package file but not the package name, or only know the keyword of the package name, we can use this to search, then install or uninstall the package.

Query in rpm. Syntax: rpm-qa | grep keyword

Instance: rpm-qa | grep screen, which filters out the desired results and then performs corresponding operations. Query in yum

Method 1: Syntax: yum list installed | grep keyword

Instance: yum list installed | grep screen Method 2: Syntax: yum provides keyword

Instance: yum provides screen

Uninstall the Software Package

Uninstall syntax in rpm: rpm-e package name

Example: uninstall syntax in rpm-e screen yum: yum remove package name

Instance: yum remove screen-4.0.3-19.el6.x86_64.rpm

The above are some of our commonly used commands. We usually use these three commands, which combine queries with the other two to complete most of our operations.

[Note]: When installing and uninstalling the package, yum is able to install the package dependency. Some rpm commands that cannot be installed at one time can be installed with yum. In addition, we can use this command when uninstalling this link. Yum history undo 4 where 4 is the fourth in the list and Undo is reverse execution. As shown in the figure, the first is an installation command, and the reverse is to uninstall it. If we use yum to install five packages based on dependencies, when we use undo, we can reverse uninstall these five packages.
