Administration's console has no figures

I installed the couchbase4.1 on CentOS 7.2,there has 5 nodes,i met a problem when i use console,that only one node’s console has figure,others doesn’t has
figures,it is blank

Did you do a standard install from RPM or non-root install? Is the user that is running the Couchbase processes SUDO?

i installed by root, use rpm -ivh

i had solved the problem, because some node’s time not same with the master in the cluster,i sync the all node’s time,it is working.
