Failed when using none-root user with ssh-key auth install Vertica Cluster nodes
Failed when using none-root user with ssh-key auth install Vertica Cluster nodes There is a problem in Vertica Cluster installation using none-root user with sudo command. The test case is describing below: I try to install a 3 nodes Cluster on HPCS Node1: Public IP: 220.127.116.11 Private IP: 10.7.31.42 Node2: Public IP: 18.104.22.168 Private IP: 10.7.31.37 Node3: Public IP: 22.214.171.124 Private IP: 10.7.30.169 Using jbossadm user running sudo command, I successfully installed first and second nodes, but in the 3rd nodes installation I got the following errors, which indicate that in 3rd node the passwordless ssh connection not configured. Actually I did configured passwordless ssh connection both for root and jbossadm user(tested that I can login as root/jbossadm via ssh into other 2 nodes without password), and the second node was installed with same command without problem. Any one have experiences in using none-root user to install cluster Another question, after I success installed cluster, if I disable root login, is that Cluster could work properly. Thanks Rosso
