Yum usage and yum usage

I will not explain how to configure the repository here. Here I will only list the more practical usage of yum.

Yum install packagename # installation package

Yum remove packagename # delete a software package

Yum groupinstall packagegroup # Use the grouplist list that can be installed

Yum clean all # Clear the cache. The cache path is/var/cache/yum.

Yum localinstall rpmfile # Install the local package, -- nogpgcheck does not check the signature

Yum provides "*/gethostip" # used to find the package to be installed by the gethostip command

Yum list all # list all software packages

Yum list updates # view the packages that can be upgraded in the system

Yum update packagename # Upgrade the specified package

Yum info packagename # package details

Yum groupinfo packagegroup # Group details

Yum search packagename # Name of the fuzzy search package

Yum reinstall packagename # reinstall the installation package

Yum install (update) kernel # Upgrade the kernel and use uname-r to view the current kernel version

Createrepo-v path # create a software repository and generate a repodata folder. The path should be the upper-level directory of repodata.

In the repository configuration, You need to configure an Errata repository. After Successful Configuration, you can use the yum update command.
