How to install Yum server in redhat 7/centos7
Issue
- How to set up yum repository to use locally-mounted DVD with Red Hat Enterprise Linux (RHEL) 7
- Would like to upgrade server from RHEL 7.x to RHEL 7.y
- Have a secure environment that will never be connected to the internet, but still needs to be updated
- Way to update the packages on server, with no satellite server and servers disconnected from internet
- Offline patches for Red Hat systems
- How do I create a local repository in RHEL 7?
Resolution
Please note: If the system is registered to Red Hat Network,yum
can be run with the --noplugins
option to prevent it from connecting to RHN. The safer option would be
to unregister the system to avoid updating to the latest release.1. Mount the RHEL 7 installation ISO to a directory like
/mnt
, e.g.# mount -o loop RHEL7.1.iso /mnt
If you use DVD media , you can mount like below.
# mount /dev/sr0 /mnt
2.
Copy themedia.repo
file from the root of the mounted directory to/etc/yum.repos.d/
and set the permissions to something sane, e.g.:
# cp /mnt/media.repo /etc/yum.repos.d/rhel7dvd.repo
# chmod 644 /etc/yum.repos.d/rhel7dvd.repo
3.
Edit the new repo file, changing the gpgcheck=0
setting to 1
and adding the following 3 linesenabled=1
baseurl=file:///mnt/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
In the end, the new repo file could look like the following (though the mediaid
will be different depending on the version of RHEL):
[InstallMedia]
name=DVD for Red Hat Enterprise Linux 7.1 Server
mediaid=1359576196.686790
metadata_expire=-1
gpgcheck=1
cost=500
enabled=1
baseurl=file:///mnt/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
4.
clear the related caches by
yum clean all
andsubscription-manager clean
once
# yum clean all
# subscription-manager clean
5.
check whether you can get the packages list from the DVD repo
# yum --noplugins list
6.
if no problem , you will update
# yum --noplugins update
