cannot find a valid baseurl for repo: base/7/x86_64(2024) different but best solution

Welcome to our tutorial on resolving the error “cannot find a valid baseurl for repo: base/7/x86_64” in CentOS 7. In this video, we will guide you through a step-by-step method to fix this issue by updating your repository URLs to point to the CentOS vault repositories.
1. **Backup your existing repo files** (just in case you need to revert back):

“`
mkdir /etc/yum.repos.d/backup

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/backup/
mv /etc/yum.repos.d/CentOS-CR.repo /etc/yum.repos.d/backup/
mv /etc/yum.repos.d/CentOS-Debuginfo.repo /etc/yum.repos.d/backup/
mv /etc/yum.repos.d/CentOS-fasttrack.repo /etc/yum.repos.d/backup/
mv /etc/yum.repos.d/CentOS-Media.repo /etc/yum.repos.d/backup/
mv /etc/yum.repos.d/CentOS-Sources.repo /etc/yum.repos.d/backup/
mv /etc/yum.repos.d/CentOS-Vault.repo /etc/yum.repos.d/backup/
mv /etc/yum.repos.d/CentOS-x86_64-kernel.repo /etc/yum.repos.d/backup/

“`

2. **Create a new CentOS-Base.repo** with the updated URLs:

“`
vi /etc/yum.repos.d/CentOS-Base.repo

“`

3. **Add the following content to the new repo file**:

“`
[base]
name=CentOS-$releasever – Base
baseurl=http://vault.centos.org/7.9.2009/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

[updates]
name=CentOS-$releasever – Updates
baseurl=http://vault.centos.org/7.9.2009/updates/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

[extras]
name=CentOS-$releasever – Extras
baseurl=http://vault.centos.org/7.9.2009/extras/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

[centosplus]
name=CentOS-$releasever – Plus
baseurl=http://vault.centos.org/7.9.2009/centosplus/$basearch/
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

“`

4. **Save the file and exit the editor**.
5. **Clear the yum cache** to ensure it picks up the new repo configuration:

“`
yum clean all

“`

6. **Update the system** to verify that the new repo URLs are working:

“`
yum update

“`

This should resolve the issue by pointing yum to the CentOS vault repositories, which are the official repositories for older releases of CentOS.
Why Do We Need This?
This issue arises because the standard CentOS 7 repositories are no longer maintained and have been moved to the vault. By updating your repository URLs to the vault repositories, you ensure that yum can access the necessary metadata and packages for updates and installations. This fix is essential for maintaining and securing your CentOS 7 system.
