The Nautilus production support team and security team had a meeting last month in which they decided to use local yum repositories for maintaing packages needed for their servers. For now they have decided to configure a local yum repo on Nautilus Backup Server. This is one of the pending items from last month, so please configure a local yum repository on Nautilus Backup Server as per details given below.
a. We have some packages already present at location /packages/downloaded_rpms/ on Nautilus Backup Server.
b. Create a yum repo named localyum and make sure to set Repository ID to localyum. Configure it to use package's location /packages/downloaded_rpms/.
c. Install package samba from this newly created repo.
Introduction
Local Yum repositories are essential in environments without internet access, where consistent package versions are required, or when custom packages need to be maintained. This guide covers the complete process of configuring a local repository and installing packages from it.
Why Use a Local Repository
Local repositories provide offline availability, ensuring systems can install packages without internet connectivity. They guarantee consistent versions across all servers, accelerate installation and updates, support custom packages, and enhance security by controlling exactly which packages are available.
Prerequisites
- Linux server with root access
- Directory containing RPM packages (
/packages/downloaded_rpms/) - Yum installed on the system
- Basic command-line knowledge
Step-by-Step Configuration
1. Connect to the Server
ssh clint@stbkp01
sudo su -
2. Verify the Packages Directory
ls -la /packages/downloaded_rpms/
Confirm the directory contains the required RPM packages.
3. Create the Repository Directory
mkdir -p /etc/yum.repos.d/
4. Create the Repository Configuration File
cat > /etc/yum.repos.d/localyum.repo << EOF
[localyum]
name=localyum
baseurl=file:///packages/downloaded_rpms/
enabled=1
gpgcheck=0
EOF
5. Verify the Repository
yum repolist all
The output should show the repository as enabled.
6. Install the Package
yum install -y samba
7. Verify Installation
rpm -qa | grep samba
samba --version
Repository Configuration Explained

1 | Repository active |
gpgcheck |
0 | GPG checking disabled |
Complete One-Line Setup
cat > /etc/yum.repos.d/localyum.repo << EOF && yum repolist && yum install -y samba
[localyum]
name=localyum
baseurl=file:///packages/downloaded_rpms/
enabled=1
gpgcheck=0
EOF
Verification Commands
# Check repository
yum repolist | grep localyum
# Check installed packages
rpm -qa | grep samba
# Check package details
rpm -qi samba
# Verify samba version
samba --version
Expected Output
[root@stbkp01 ~]# yum repolist
repo id repo name status
localyum localyum enabled
[root@stbkp01 ~]# yum install -y samba
Dependencies resolved.
Installed:
samba-4.24.5-2.el9.x86_64
Complete!
[root@stbkp01 ~]# rpm -qa | grep samba
samba-4.24.5-2.el9.x86_64
Troubleshooting
Issue: /etc/yum.repos.d/ directory not found
Solution: mkdir -p /etc/yum.repos.d/
Issue: Repository not showing in yum repolist
Solution: Check syntax, verify path, run yum clean all
Issue: GPG key errors
Solution: Set gpgcheck=0 or import the correct key
Summary
- Repository configured:
localyum - Package location:
/packages/downloaded_rpms/ - Package installed:
samba - Repository verified and functioning
The local Yum repository is now ready for use on the server.
