Problem :
Ive tried what this article describes:
yum install yum-security
Next step is
yum list-security
but the result of this is:
Loading mirror speeds from cached hostfile
* base: mirror.anl.gov
* epel: mirrors.liquidweb.com
* extras: mirror.wiredtree.com
* updates: centos.mirrors.tds.net
* webtatic: us-east.repo.webtatic.com
Killed
Any idea why it gets killed? I don’t care how if there is another way to do it I’m fine with that as well.
The system version is this
2.6.32-042stab088.4 #1 SMP Sat Jun 21 00:15:09 MSK 2014 x86_64 x86_64 x86_64 GNU/Linux
Edit:
Running yum clean all and then trying it again didn’t help:
[root@foobar burzum]# yum clean all

Solution :
Late answer, but this is typically due to memory exhaustion. The security plugin seems to use extra memory.
Good luck implementing articles from 2009. CentOS 6/7 doesn’t supply “security” categories inside package metadata (unlike RHEL), so nevermind what yum plugin magic you use, it won’t do.
The best practice is to update all, and in my practice the complete updates are still conservative enough so that problems are very rare.
Working solution: Centos Security updates only
sudo yum install yum-plugin-changelog pcre-devel python-pip
mkdir /var/lib/centos-package-cron
pip install centos_package_cron
centos-package-cron --output stdout --forceold | pcregrep -M 'Packages:[^:]*' | grep -o "[^* ]*" | grep -v 'Packages:' | grep -v 'References' | sort | uniq | xargs yum -y update
You need to install the plugin called yum-plugin-security. The commands give you the security information.
