To create a local YUM (Yellowdog Updater Modified) server, you'll need a system with access to the packages you want to host locally. This local server can then be used to distribute packages to other systems on the same network, improving installation and update speeds and reducing external internet dependencies. Here's a step-by-step guide to creating a local YUM server:
Steps To follow:
1 - Set Up a CentOS/RHEL System (or Similar)
2 - Install Required Software
3 - Prepare the Package Repository
4 - Create the YUM Repository Metadata
5 - Configure HTTP Server (Apache)
6 - Configure Firewall (if necessary)
7 - Verify the YUM Repository
8 - Configure YUM Clients:
9 - Update YUM Cache on Clients
10 - Install Packages from Local Repository
1: Set Up a CentOS/RHEL System (or Similar):
Choose a CentOS, Red Hat Enterprise Linux (RHEL), or a similar distribution as the base for your local YUM server. You can also use a virtual machine for this purpose.
2: Install Required Software: Open a terminal and make sure your system is up to date. Install the necessary packages:
bashsudo yum update
sudo yum install epel-release
sudo yum install createrepo httpd3: Prepare the Package Repository: Create a directory to store the RPM packages you want to make available via YUM. For example, you can use the following directory structure:
bashsudo mkdir -p /var/www/html/local-yum/repo
Copy or download the RPM packages you want to host into this directory.
4: Create the YUM Repository Metadata: Now, you need to generate metadata for the repository using the
createrepo
command. This metadata helps YUM clients understand the package dependencies and other information.bashsudo createrepo /var/www/html/local-yum/repo
5: Configure HTTP Server (Apache): Since YUM clients will access the repository over HTTP, you need to configure a web server. The most common choice is Apache.
bashsudo systemctl start httpd
sudo systemctl enable httpd6: Configure Firewall (if necessary): If you have an active firewall, you need to open the HTTP port (port 80) to allow incoming connections.
bashsudo firewall-cmd --add-service=http --permanent
sudo firewall-cmd --reload7: Verify the YUM Repository: At this point, your local YUM repository should be set up and accessible over HTTP. To verify it, open a web browser and go to
http://your_server_ip/local-yum/repo/
. You should see the repository's directory listing and therepodata
folder containing the repository metadata.8: Configure YUM Clients: On the client machines, create a
.repo
file in the/etc/yum.repos.d/
directory to configure YUM to use your local repository. For example:bashsudo vi /etc/yum.repos.d/local-yum.repo
Add the following content to the file (replace
your_server_ip
with the IP address or hostname of your YUM server):makefile[local-yum]
name=Local YUM Repository
baseurl=http://your_server_ip/local-yum/repo
enabled=1
gpgcheck=0 # If you're not using GPG signingSave the file and exit the editor.
9: Update YUM Cache on Clients: On the client systems, update the YUM cache to include the new local repository:
bashsudo yum clean all
sudo yum makecache10: Install Packages from Local Repository: Now, you can install packages from your local repository as you would with any other YUM repository:
bashsudo yum install package_name
That's it! You now have a local YUM server that provides packages to your local network. Keep in mind that you'll need to regularly update the packages in your local repository to keep it up to date with the latest versions. Additionally, you can explore further configurations, such as setting up GPG signing for added security.
