[DE72]: Sometimes have to rerun install --role=server #481

Closed retreved closed 11 years ago

retreved commented 11 years ago

I have had occasional problems after installin role--server and role=dashboard where I have to rerun --role=server due to 403 errors returned from opencentercli. All nodes with the agent check in and show green.

root@opencenter:~# opencentercli node list

Executing Adventure 2, Install Chef Server on Node 5, chef-server 2013-04-02 16:48:00,230 - opencenter.adventure - WARNING - status code 403 on post

Manually restarting the services does not fix the problem. The workaround is to rerun './install.sh role=server'.

@retreved: can you provide a better view of the steps taken to reproduce this? Did it look like this?

  1. Install.sh with --role=server on node4
  2. install.sh with --role=dashboard on node4
  3. Install.sh with --role=agent on node{5,6,7,8}
  4. opencentercli adventure execute 5 2

According to https://privatecloudforums.rackspace.com/viewtopic.php?f=4&t=401, this happens when you install the agent role on the OpenCenter server node.

@kstev the server install automatically does the agent as well.. So you do not need to run the last install command.. Can you verify that resolves the issue?

galstrom21 commented 11 years ago

All you need on the server is the server role and the dashboard role.

kstev commented 11 years ago

Correct. That's what I've been telling folks. Perhaps this is not a 'bug' but evidence that the install instructions are not clear or that there should be some sort of sanity check if you try to run the agent role install on the 1st and only server node?

galstrom21 commented 11 years ago

@kstev: which documentation is instructing you to run the agent install on the server node? Let me know and Ill file a docbug.

ddaeschler commented 11 years ago

In this documentation: http://www.rackspace.com/knowledge_center/article/installing-rackspace-private-cloud-software

Immediately after the "Install the OpenCenter User Interface" section, under "Install OpenCenter Agent" the instructions are simply:

"Run the following curl command on each node that will be managed with OpenCenter:"

I think that is what is tripping people up. Adding something like "(note it is not necessary to install the OpenCenter Agent on the OpenCenter server node)" may resolve the problem.

galstrom21 commented 11 years ago

@ddaeschler: thanks for the link.. I have filed a docbug to amend the guide with a note about the agent already being installed on the server.
