CentOS 7.9.2009 repository configuration

By 1 min read

As for year 2025 there is no more updates for CentOS 7.9.2009. Moreover you need to adjust repository file as network locations changed a little bit. So edit /etc/yum.repos.d/CentOS-Base.repo as follows:

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

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

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

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

Then recreate yum cache:

Bash
sudo yum clean all
sudo yum makecache

And if necessary:

Bash
sudo yum update yum

Now you are good to go with packages installation. If installing rkhunter, remember to install epel-release and then

Bash
sudo yum install rkhunter --enablerepo epel

in case you did no enable EPEL to be enable by default which is the most probably situation.
