Here’s how to install a RPM locally. Download the RPM first.
wget https://domain.com/path/to/file/rpmfile1.rpm wget https://domain.com/path/to/file/rpmfile2.rpm |
wget https://domain.com/path/to/file/rpmfile1.rpm wget https://domain.com/path/to/file/rpmfile2.rpm
Then install RPM from a local file.
yum localinstall /path/to/rpmfile1.rpm yum localinstall /path/to/rpmfile2.rpm |
yum localinstall /path/to/rpmfile1.rpm yum localinstall /path/to/rpmfile2.rpm
Here’s how to disable plugin in Yum repos.
# check which plugins are enabled yum repolist # disable plugins yum update --disableplugin=product-id,subscription-manager # check agin yum repolist |
# check which plugins are enabled yum repolist # disable plugins yum update --disableplugin=product-id,subscription-manager # check agin yum repolist
If that doesn’t work, check the individual config files of each plugin.
cd /etc/yum/pluginconf.d/ vim product-id.conf vim subscription-manager.conf |
cd /etc/yum/pluginconf.d/ vim product-id.conf vim subscription-manager.conf
Disable it.

[main] enable=0

Add a yum repo manually by adding a configuration file in /etc/yum.repo.d/ directory.
cd /etc/yum.repos.d/ vi newrepo |
cd /etc/yum.repos.d/ vi newrepo
Add the following.
[newrepo] name=New Repo for RHEL/ CentOS $releasever - $basearch baseurl=http://newrepo.domain.com/centos/$releasever/$basearch/ enabled=1 gpgcheck=1 gpgkey=http://newrepo.domain.com/RPM-GPG-KEY.txt |
[newrepo] name=New Repo for RHEL/ CentOS $releasever - $basearch baseurl=http://newrepo.domain.com/centos/$releasever/$basearch/ enabled=1 gpgcheck=1 gpgkey=http://newrepo.domain.com/RPM-GPG-KEY.txt
You may need to import the key.
rpm --import http://newrepo.domain.com/RPM-GPG-KEY.txt |
rpm --import http://newrepo.domain.com/RPM-GPG-KEY.txt
Finally, test the new repo by running the following.
yum update -y yum install new-package |
yum update -y yum install new-package
