To manually sign the certificate
<pre>'''#puppetca –sign <certificate CN>'''</pre>
note: it is done in puppet master. To list the requsete certificate, issu the commad
<pre>'''#puppetca –list'''</pre>
5)Puppet receives the signed certificate. Once the puppet receives the certificate, it will start configuration run immediately.
On server, In this case it will be Hongkong.proximity.on.ca
<pre> '''#yum install puppet-server'''</pre>
it will install puppetmaster and puppet on the server which is to be as puppetmaster.
<pre> '''#yum install mysql-server ruby-mysql'''</pre>
<pre> '''#yum install ruby-RRDtool'''</pre>
it will install ruby library.
On client, in this case it will be Ireland.proximity.on.ca
it will install puppet client on the client system.
On the server, Hongkong
<pre>
#ls /etc/puppet
</pre>
a) carete sudo.pp, vi /etc/puppet/manifests/class/sudo.pp
<pre>
# /etc/puppet/manifests/classes/sudo.pp
class sudo {
mode => 440, }
}
</pre>
b) create site.pp, vi /etc/puppet/manifests/site.pp
<pre>
# /etc/puppet/manifests/site.pp
import "classes/*"
include sudo
}
</pre>
c) start the puppet master.
<pre>'''#puppetmasterd –mkusers'''</pre>
this option will create the puppet user that is needed.
Once the puppetmaster daemon is stated, it will create the necessary files and folders under /var/lib/puppet.
should have bucket, clientsbucket, facts, reports, ssl, yaml, class.txt, client_yaml, l ib, rrd, state
all the details information about these files and folder will be included in the next blog.
<pre> '''#'''service puppetmaster start'''</pre>
d) start the puppet client.
On the client, Ireland
<pre>'''#puppetd –verbose'''</pre>
when the puppet client daemon starts, it creates the necessary certificate and waits for the certificate to be signed by the puppetmaster.
On the server
<pre>'''#puppetca –list'''</pre>
this will list the all the requested certificate that are to be signed by puppetmaster.
== '''Release 0.2''' ==
'''Functional with file server'''
1) file server configuration: For the the configuration to be saved
'''File server configuration'''
The last release 0.1 was installing the basic puppet installation and gets the puppet working. In the puppet master there should be service that should store and deliver the needed configuration files. Puppet can be act as the file server.
Ex:
<pre>
file { “resolv.conf”:
}
</pre>
The fileserver configuration is managed by the fileserver.conf that is located in the /etc/puppet directory by default. But using the following command can change the location.
In the puppet master
<pre>
#puppetmasterd --fsconfig /usr/local/etc/puppet/fileserver.conf
</pre>
The fileserver.conf file defines paths to serve files from and it has the access control that specifying which nodes can access these files.
Here is an example
<pre>
[configuration]
allow *.senecac.on.ca
deny *
</pre>
Here the each path being served is called a module. For example , configuration is a module. The use of modules allows puppet to abstract and simplify file system configuration and paths. The path statement specifies the location on the puppet master server where the files being served are located.
Lets see if we want to get the resolv.conf file from the configuration module in the file server, we simply specify as follows
<pre>
file { “/etc/resolv.conf”:
}
</pre>
what happens above is that, the file resource type need the titled /etc/resolv.conf file that is saved in the configuration module( /var/lib/puppet/files/configurtion/resolv.conf) is retrieved by the puppet.
Puppet://puppetmaster/module/files
Ex: <pre>source => “puppet://puppetmaster/configuration/resolv.conf”</pre>
This is for only single file is being down loaded by puppet and applied to the nodes. But if we want to download the full directory, there is a small changed needs to be done when specify the source.
<pre>
file { “/etc/pam.d”:
}
</pre>
What we have done here is that instead of just specifying the file resource type, we specify the directory /etc/pam.d. Therefore, the puppet will download pam.d directory and applied to the nodes. The recurse attribute and value true tells the puppet server that it should download all the files from the directory.
