问题
I am trying to install Client tools on RHEL/OpenShift free server. However following https://developers.openshift.com/en/getting-started-rhel-centos.html#client-tools I am supposed to execute some super user commands which gives a permission error. Do I need to do something to enable super user access on my virtual machine?
sudo su
bash: /usr/bin/sudo: Permission denied
回答1:
OpenShift Online does not allow you to gain super user access, so I don't think you will be able to install the client tools on your OpenShift servers. The OpenShift client tools (rhc) aren't meant to be installed on your OpenShift servers, they are meant to be installed on your local computer.
