Updating the nodes

Work done December 2018

Nodes 1-10 all now have ssmtp installed.

Nodes 6, 7 and 10 updated to 6.10.

Node 8 doesn't connect to the redhat subscription manager so cannot update that

Process

sudo subscription-manager remove --all
sudo subscription-manager unregister
sudo subscription-manager clean
sudo subscription-manager register
sudo subscription-manager refresh
sudo subscription-manager attach --auto


then

yum clean all
yum update


If you see an error

http://apt.sw.be/redhat/el6/en/x86_64/rpmforge/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 503 Service Unavailable"

It's due to the rpmforge repo no longer existing at that location. removing /etc/yum.repos.d/rpmforge.repo fixes the error.

If you see the error

Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again

It's not due to the /etc/yum.repos.d/epel.repo file, it's because there's mirror-rpmforge-*.repo files, which need to be removed.

I then installed ssmtp using

wget http://dl.fedoraproject.org/pub/epel/6/x86_64/Packages/s/ssmtp-2.61-22.el6.x86_64.rpm
rpm -ivh ssmtp-2.61-22.el6.x86_64.rpm

Identifying differences

On each node

yum list > rpmList_nodeX.txt
subscriptionManager repos --list > subManList_nodeX.txt

Then got all files with

for i in {1..10}; do echo scp node$i *_node$i.txt ./; done
