CentOS 7 Vault Repositories (End-of-Life - Limited Use)

This repository contains vault .repo files for the CentOS 7 and scripts used to generate those repos.

Important Note:

CentOS 7 reached its end-of-life (EOL) on December 31, 2021. These vault repositories provide limited access to critical security updates for a short grace period only. They are not intended as a long-term solution.

This repository is intended for:

• Informational purposes: See the structure and content of the CentOS 7 vault repositories.
• Emergency situations: Potentially address critical security vulnerabilities on a system that cannot be migrated immediately.

Warning:

Using these repositories for ongoing use is strongly discouraged due to limited availability and lack of future updates. It is highly recommended to migrate to a supported alternative like Rocky Linux or AlmaLinux for continued security and stability.

How to use the scripts

We have created two scripts that are used to generate and enable or disable repositories.

1. generate_base_repos.sh: Use this to generate repositories in .repo.
2. enable_repos.sh: Use this to enable or disable repositories

Step 1: Clone the repository

git clone https://github.com/cloudspinx/centos7-vault-repositories.git
cd centos7-vault-repositories

If you don't have git, you can download the scripts using curl:

curl -fsSL -O https://raw.githubusercontent.com/cloudspinx/centos7-vault-repositories/main/generate_base_repos.sh
curl -fsSL -O https://raw.githubusercontent.com/cloudspinx/centos7-vault-repositories/main/enable_repos.sh

Step 2: Run script to generate key vault repositories:

bash generate_base_repos.sh

See example output:

Created centos7_repos/atomic.repo
Created centos7_repos/centosplus.repo
Created centos7_repos/dotnet.repo
Created centos7_repos/extras.repo
Created centos7_repos/fasttrack.repo
Created centos7_repos/os.repo
Created centos7_repos/rt.repo
Created centos7_repos/updates.repo
Generated .repo files for all repositories in centos7_repos.

Step 3: Run script to enable or disable vault repos. Choose ones to enable and ones to disable accordingly.

bash enable_repos.sh

See example:

Do you want to enable repository 'atomic' (y/n)? n
Disabled repository 'atomic'.
Do you want to enable repository 'centosplus' (y/n)? y
Enabled repository 'centosplus'.
Do you want to enable repository 'dotnet' (y/n)? n
Disabled repository 'dotnet'.
Do you want to enable repository 'extras' (y/n)? y
Enabled repository 'extras'.
Do you want to enable repository 'fasttrack' (y/n)? y
Enabled repository 'fasttrack'.
Do you want to enable repository 'os' (y/n)? y
Enabled repository 'os'.
Do you want to enable repository 'rt' (y/n)? n
Disabled repository 'rt'.
Do you want to enable repository 'updates' (y/n)? y
Enabled repository 'updates'.
Repository enablement process completed.

Step 4: Backup current repositories

mkdir ~/repos_backup
sudo mv /etc/yum.repos.d/* ~/repos_backup

Step 5: Copy generated repository files to /etc/yum.repos.d/

sudo cp -r centos7_repos/* /etc/yum.repos.d/
