I have already written an article to download an individual rpm along with all it’s dependencies, in this article I will share the steps to download entire repository from CentOS / RHEL 7 to your local Linux node. To download the repository you will need one time active internet access.

Once the rpms are downloaded the you can configure a local repository with these rpms for offline usage. Although downloading (syncing) the entire repository content to local Linux node may take some time depending upon your internet speed and the content of the repository.

How to download entire repository from CentOS RHEL 7 for offline use

I have a node which is in a private network and does not has access to the Internet so I always have to go through a lot of trouble in case I have to install some additional rpm with multiple dependencies. Using this method I have created a local repository in my private network which helps me download required rpm without internet.

 

Install the required packages

First install the yum-utils and createrepo packages on the system which will be used for the syncing purpose:

NOTE:
On RHEL system you must have an active subscription to RHN or you can configure a local offline repository using which “yum” package manager can install the provided rpm and it’s dependencies.
# yum install yum-utils createrepo

 

Download entire repository from CentOS 7

On CentOS unlike RHEL you do not need to perform any additional subscription related activity to get the access to their repository. As soon as you install CentOS, you will find below list of repo files under /etc/yum.repos.d

[root@openstack yum.repos.d]# ll
total 40
-rw-r--r--. 1 root root 1664 Aug 30  2017 CentOS-Base.repo
-rw-r--r--. 1 root root 1309 Aug 30  2017 CentOS-CR.repo
-rw-r--r--. 1 root root  649 Aug 30  2017 CentOS-Debuginfo.repo
-rw-r--r--. 1 root root  314 Aug 30  2017 CentOS-fasttrack.repo
-rw-r--r--. 1 root root  630 Aug 30  2017 CentOS-Media.repo
-rw-r--r--. 1 root root 1331 Aug 30  2017 CentOS-Sources.repo
-rw-r--r--. 1 root root 3830 Aug 30  2017 CentOS-Vault.repo

 

Not all of these repositories will be in enable state, some of them may be in disable state. To check the currently active repos use below command

To download (or sync) a repository use the below command

# reposync --gpgcheck -l --repoid=<repo_id> --download_path=<path>

Here replace repo_id with the ID of the repository you wish to sync locally, for example in the below command I am syncing extras repo and downloading the rpms to /tmp

# reposync --gpgcheck -l --repoid=extras --download_path=/tmp
NOTE:
In the targeted directory, there will be a new directory named after the Repository ID. Inside there is all the packages

To have access to the group data for the newly synced repo, please run the createrepo command as follows:

# cd /tmp/<channel-id>
# createrepo -v /tmp/<channel-id>/

For example:

# cd /tmp/extras
# createrepo /tmp/extras

 

Download entire repository from RHEL 7

First of all on RHEL 7 you must first register your node to the Red Hat Network.

# subscription-manager register
Registering to: subscription.rhsm.redhat.com:443/subscription
Username: deepak
Password:
The system has been registered with ID: 04bbc67c-f45c-47e9-9bec-122e8cd10c9d

Next check the list of entitlements to your ID

# subscription-manager list --available --all

Once you know which entitlement suits your requirement, then attach the POOL ID for your system

# subscription-manager attach --pool=<pool_id>

Next enable all the repositories you wish to use. You can check all the subscribed repositories using the below command

# yum repolist all

Once you have the repo id which you wish to download use the same command as we use with CentOS 7

Syntax:

# reposync --gpgcheck -l --repoid=<repo_id> --download_path=<path> --downloadcomps --download-metadata

Here replace repo_id with the ID of the repository you wish to sync locally, for example in the below command I am syncing extras repo and downloading the rpms to /tmp

# reposync --gpgcheck -l --repoid=rhel-7-server-openstack-10-devtools-rpms --download_path=/tmp --downloadcomps --download-metadata
NOTE:
In the targeted directory, there will be a new directory named after the Repository ID. Inside there is all the packages

To have access to the group data for the newly synced repo, please run the createrepo command as follows:

# cd /var/www/html/<channel-id>
# createrepo -v /var/www/html/<channel-id>/ -g comps.xml

For example:

# cd /var/www/html/rhel-7-server-openstack-10-devtools-rpms

# createrepo -v /var/www/html/rhel-7-server-openstack-10-devtools-rpms/ -g comps.xml

So now I can start using this repository offline.

 

Lastly I hope the steps from the article to download entire repository from CentOS /RHEL 7 to your local Linux node was helpful. So, let me know your suggestions and feedback using the comment section.
