VMmanager 6: Administrator guide

How to configure a cluster node in OVH data center?

ISPSystem

In OVH data center, operating systems on servers use local repositories by default. Currently, using these repositories on the server may cause problems when adding the server as a node of the VMmanager cluster.

To change the repositories, perform the following in the files /etc/yum.repos.d/CentOS-Base.repo and /etc/yum.repos.d/CentOS-fasttrack.repo:

  1. Comment out baseurl strings with a link to local repositories.
  2. Uncomment mirrorlist strings with a link to the official list of CentOS repositories.
Example of file /etc/yum.repos.d/CentOS-Base.repo
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.
