Hi everybody,
I configured a cluster between two nodes, following the wizard in
Settings->Cluster menu. After inserting IPs and names of the two nodes and
root password of the second node, I clicked on "Configure RSA connections
between nodes": the page reloads but no success messages appears, so when I
click on "Configure cluster type" to save and enable cluster
configurations, the error "configure RSA connection first" appears.
The two nodes are in the same subnet without firewall between them, and DNS
is working properly; I can mutually ping and login as root in the two nodes
without problems.
I made the cluster working by manually exchanging the RSA keys between the
two nodes, I used on each node:
ssh-keygen
ssh-copy-id -i ~/.ssh/id_rsa.pub root@node
After this I can login as root between servers without password, cluster
status and tests on web interface complete successfully.
What has happened? I have configured other Zen Load clusters in our
environment, but I have never encountered problems like this. The two nodes
are virtual machines, the only difference is that the secondary node is on
an older hypervisor, that is slower than the other one, so the VM perform
poorly...maybe a timeout problem? I searched in Zen Load logs, but I did
not find anything.
I used Zen load balancer distro v. 3.03 .
Have a nice day.
