After I installed starcluster to bring up a cluster using ami-a3d126c8. I can't successfully start the rstudio session on the master node, but I can on the worker nodes.
Using the web browser to connect to the Rstudio Server's login page on the master node, after log in with username 'ubuntu' and password 'bioc', i get the rstudio initialization error: unable to connect to service. I ssh into the master node, and do some checking. I ran command 'su rstudio-server verify-installation', and I got
ERROR system error 13 (Permission denied).
On the other hand however, if i connect to any of the worker nodes, i can successfully log in to R-studio server. I also try just bringing up one-node cluster which has only the master node, i can log in successfully too.
Can anyone help? This will be much appreciated.
thank you so much
