Installing and Configuring the Puppet Agent[edit]

These steps show how to install and configure the Puppet agent on a host. The Puppet agent must be configured so that Red Hat Satellite Server can list all available hosts in All Hosts.== Installing and Enabling the Puppet Agent: ==

Open a terminal console and login as root on the command line.
Install the Puppet agent using the following command:

# yum install puppet== Configuring the Puppet Agent: ==

Prerequisites:

You must meet the following conditions before continuing with this task:* The host must be registered to the Red Hat Satellite Server.

The Red Hat Common repository must be enabled.
Puppet packages must be installed on the host.

Configure the Puppet agent by changing the /etc/puppet/puppet.conf file:[edit]

# vim /etc/puppet/puppet.conf

[main]

# The Puppet log directory.

# The default value is '$vardir/log'.

logdir = /var/log/puppet

# Where Puppet PID files are kept.

# The default value is '$vardir/run'.

rundir = /var/run/puppet

# Where SSL certificates are kept.

# The default value is '$confdir/ssl'.

ssldir = $vardir/ssl

[agent]

# The file in which puppetd stores a list of the classes

# associated with the retrieved configuratiion. Can be loaded in

# the separate ``puppet`` executable using the ``--loadclasses``

# option.

# The default value is '$confdir/classes.txt'.

classfile = $vardir/classes.txt

pluginsync = true

report = true

ignoreschedules = true

daemon = false

ca_server = gd9105.gstn.org.in

server = gd9105.gstn.org.in

environment = KT_Gstn_Delhi_Library_Puppet_view_2

# Where puppetd caches the local configuration. An

# extension indicating the cache format is added automatically.

# The default value is '$confdir/localconfig'.

localconfig = $vardir/localconfig

# Where puppetd caches the local configuration. An

# extension indicating the cache format is added automatically.

# The default value is '$confdir/localconfig'.

localconfig = $vardir/localconfig

Start and enable puppet agent service:[edit]

#systemctl enable puppet

#systemctl restart puppet

Request for signing of certificate to Satellite server:[edit]

# puppet agent -t --server gd9105.gstn.org.in

Exiting; no certificate found and waitforcert is disabled== Signing client certificate from satellite server: (sap) (Sapose client hostname was gd9204.gstn.local ). ==

# puppet cert sign gd9204.gstn.local

Notice: Removing file Puppet::SSL::CertificateRequest gd9204.gstn.local at '/var/lib/puppet/ssl/ca/requests/gd9204.gstn.local.pem'

Check registration status from the client machine:[edit]

# puppet agent -t --server gd9105.gstn.org.in
