6.4. Allowing root Access to Cluster Nodes Over SSH¶
If you enable any third-party repositories like EPEL, make sure that packages from the official repository,
hci.repo, are never overwritten by packages from the third-party repositories. Do not run
yum update with such repositories enabled and disable them when you do not need them anymore. Otherwise product stability may be at risk.
In certain situations, you or the technical support team may need root access to cluster nodes via SSH. To allow root access to all nodes in the cluster, do the following:
Obtain an SSH public key from the technical support team.
Open the SETTINGS > Security > SSH screen and click ADD.
On the Add public key panel, paste the key and click ADD KEY.
To delete the key after root access is no longer required, select the key and click Delete.
