virtualbox
Add required supporting packages:
$yum install libxml2-python deltarpm python-deltarpm vsftpd
Create a directory to store the rpm files or mount a directory which contains them.
$mkdir /var/ftp/pub/localrepo
Copy rpms to /var/ftp/pub/localrepo
$cp /mnt/disk/*.rpm /var/ftp/pub/localrepo/
Add the repo config file:
$vim /etc/yum.repos.d/localrepo.repo
Add the following lines:
[localrepo]
name=Local Repository
baseurl=file:///var/ftp/pub/localrepo
gpgcheck=0
enabled=1
Build the local repository:
$createrepo -v /var/ftp/pub/localrepo
Now use the yum command that we used above to verify that yum sees the new repo:
$yum repolist
As a good practice, run clean all and update:
$yum clean all
$yum update
Remember to add the repo to any client machine that should have access to it:
Client Side Configuration
Now, go to your client systems. Create a new repository file as shown above under /etc/yum.repos.d/ directory.
$vim /etc/yum.repos.d/localrepo.repo
and add the following contents:
[localrepo]
name=Local Repository
baseurl=ftp://{IP OF LOCALREPO}/pub/localrepo
gpgcheck=0
enabled=1
Now, list out the repositories using the following command:
$yum repolist
Clean the Yum cache and update the repository lists:
$yum clean all
$yum update
