Mcollective client installation

[Deep]

Hi All,

I have installed puppet enterprise which comes with Mcollective. I have installed Puppet Master on node 1 and puppet agent on node 2 and node 3. while installing , it asked me if I want to install Mcollective. I wanted to have Mcollective client on my Puppet Master. and Mcollective servers on node 2 and node 3.

But when I checked, there was no client.cfg file created at /etc/puppetlabs/mcollective/. And Mcollective was started using server.cfg

How can I use Mcollective client on puppet Master?

I have created client.cfg but still Mcollective needs server.cfg to start. Can anybody suggest me on this please? I am new to Mcollective and trying to learn it and implement it.

Regards,

Deep

Hi,

Mcollective has 3 roles:
- the server installed in every puppet client
- the middleware installed in puppet master
- the client installed anywhere, puppet master is a good place

The client is just the utilities to call commands, it attacks the middleware, authenticate with certificates, and it is the middle ware who spread the command to every mcollective server. It doesnt have an agent running.

Just try 'mco ping' from the server/user that is the mco client to check if it works.

Regards,

Hi Jose,

Thanks for your quick response and explaining me in details. I tried mco ping command but getting below error.

error 2014/02/17 16:23:00: activemq.rb:131:in `on_ssl_connectfail' SSL session creation with stomp+ssl://mcollective@gsldev23:61613 failed: nested asn1 error

I am using below ssl configuration in client.cfg

plugin.activemq.pool.1.ssl.ca = /etc/puppetlabs/mcollective/ssl/mcollective-cacert.pem

plugin.activemq.pool.1.ssl.cert = /etc/puppetlabs/mcollective/ssl/mcollective-private.pem

plugin.activemq.pool.1.ssl.key = /etc/puppetlabs/mcollective/ssl/mcollective-cert.pem

securityprovider = ssl

# SSL plugin settings:

plugin.ssl_server_public = /etc/puppetlabs/mcollective/ssl/mcollective-public.pem

plugin.ssl_client_private = /etc/puppetlabs/mcollective/ssl/mcollective-private.pem

plugin.ssl_client_public = /etc/puppetlabs/mcollective/ssl/mcollective-public.pem

Can you tell me if this is wrong?

I don't know how puppet enterprise works with mco, but in the open source version you have to create a certificate for the user you are going to call mco and sign in with the middleware certificate.

Last time I installed PE and looked at the Mcollective install it wasn't using SSL but rather PSK only.

[Johan De Wit]

With PE, mco commands needs to be run as peadmin user, so,  su - peadmin should do the trick.

Hi Johan,

Thanks for the suggestion . it is working as peadmin user. But where I can get all these information regarding mcollective in one place. Because it took lot of time to resolve this issue. I didn't find anywhere that it should be running as a pe-admin user.
