To create a local directory from which we can install through yum,Mainly we need the “createrepo plugin of yum”

first make the directory

>mkdir pak

then copy the rpms into the directory

then use createrepo to create the repository files inside the folder

>createrepo pak

then it will make repository files and show following on success

Saving Primary metadata
Saving file lists metadata
Saving other metadata

then make a file @ /etc/yum.repos.d/pak.repo

>vim /etc/yum.repo.d/pak.repo

inside that we need name url and enable option
enable should be equal to 1 to make the repository 
active all the time.the url will have destination to 
the folder 

as follows

[pal]
Name=pak $releasever $basearch local repository
baseurl=file:///pak
enabled=1
