CentOS 7 Yum Repo Fix with One-click Script

Why did the Yum repos stop working?

CentOS 7 officially reached end-of-life (EOL) on June 30, 2024. The default Yum repositories have been removed from official and mirror servers, so yum install fails not because of slow connections, but because the repos no longer exist.

Recommended Solution: One-click Script

Use our automated script to quickly switch to the Vault archive repos:

bash <(curl -sSL https://reshub.cn/data/sh/switch-centos7-repo.sh)

This script will:

• Backup existing /etc/yum.repos.d/*.repo
• Switch to vault.centos.org repos
• Regenerate Yum cache

This restores package installation temporarily, but no further security updates will be available.

Alternative: Manual Switch to Vault

sed -i.bak 's|mirror.centos.org|vault.centos.org|g' /etc/yum.repos.d/CentOS-Base.repo
sed -i 's|^#baseurl=http://vault|baseurl=http://vault|g' /etc/yum.repos.d/CentOS-Base.repo
sed -i 's|^mirrorlist=|#mirrorlist=|g' /etc/yum.repos.d/CentOS-Base.repo
yum clean all && yum makecache

Long-term Recommendation

Since CentOS 7 is EOL, migrate to Rocky Linux or AlmaLinux for ongoing updates and community support.
