Please considerate the installation article of Master puppet in the article before from this LINK : http://unixmen.com/puppet-installation-and-configuration-to-centos-7-x64/
The articles are related to understand how puppet works
Install puppet agent to the CentOS7 x64 server
After steps for CentOS nodes in the CentOS PuppetManager.docx artcile we must install puppet agent:
First : rpm -ivh http://yum.puppetlabs.com/puppetlabs-release-el-7.noarch.rpm
[root@pupnode1 ~]# yum install net-tools –y
[root@pupnode1 ~]# yum install -y puppet
The content of the /etc/puppet/puppet.conf file will be as following (Be careful, you must set node certificate name in the certname and server in the server directive):
[main] logdir = /var/log/puppet runinterval = 10 rundir = /var/run/puppet ssldir = $vardir/ssl
[agent] classfile = $vardir/classes.txt localconfig = $vardir/localconfig server = pupmaster.unixmen.com certname = pupnode1.unixmen.com
Check the server connection(The following command will help us for troubleshooting and for that before start the daemon, use this command):
[root@pupnode1 ~]# puppet agent –server=pupmaster.unixmen.com –test –debug
If command will successfully will created file with /tmp/hello-file name.
Remove certificates
When server removes already signed certificate for agent, we must remove certificates from agent as follows:
[root@pupnode1 ~]# rm -rf /var/lib/puppet/ssl/*
Install puppet agent to the FreeBSD 10.1 x64 server
After steps for FreeBSD nodes in the CentOS PuppetManager.docx artcile we must install puppet agent. We will install agent from the ports:
root@pupnode7:~ # cd `whereis puppet | awk '{ print $2 }'`
root@pupnode7:~ # make config
root@pupnode7:~ # make -DBATCH install
Add to startup:
root@pupnode7:~ # echo 'puppet_enable="YES"' >> /etc/rc.conf
Copy the configuration files:
root@pupnode7:~ # cd /usr/local/etc/puppet/ root@pupnode7:~ # cp auth.conf-dist auth.conf root@pupnode7:~ # cp puppet.conf-dist puppet.conf
You can download the content of the /usr/local/etc/puppet/puppet.conf file from this link.
We must add runinterval = 10 line in the [agent] topic, remove [main] topic and change hostname directives as you server hostname (This means change every place where pupnode7 to yours).
Puppet require know about root CA’s and for that we will install ca_root_nss from the ports:
root@pupnode7:~ # cd /usr/ports/security/ca_root_nss root@pupnode7:~ # make –DBATCH install
Manifests as install provider uses portupgrade and portmaster. We must install them:
root@pupnode7:~ # cd `whereis portupgrade | awk '{ print $2 }'`
root@pupnode7:~ # make –DBATCH install
root@pupnode7:~ # cd `whereis portmaster | awk '{ print $2 }'`
root@pupnode7:~ # make –DBATCH install
Check the connection:
root@pupnode7:~ # puppet agent --server=pupmaster.unixmen.com --test --debug
Or:
root@pupnode9:~ # puppet agent --test
Note: Be careful, in manifests must not be anything blocks configuration your server. Else will be “Error: Could not retrieve catalog from remote server: Error 400 on SERVER:” error.
Start the daemon:
root@pupnode8:~ # /usr/local/etc/rc.d/puppet start
Install puppet agent to Ubuntu 14.04 x64 server
After steps for Ubuntu nodes in the CentOS PuppetManager.docx artcile we must install puppet agent. In default ubuntu repositories puppet version is very old and for that we will add the puppet repositories from the puppet official site:
root@pupnode6:~# wget https://apt.puppetlabs.com/puppetlabs-release-trusty.deb root@pupnode6:~# dpkg -i puppetlabs-release-trusty.deb root@pupnode6:~# apt-get update root@pupnode6:~# apt-get install puppet
Look to the version:
root@pupnode6:~# puppet -V 3.8.3
Our puppet version is 3.8.3. For automatically update this version add the following lines to the /etc/apt/preferences.d/00-puppet.pref file:
# /etc/apt/preferences.d/00-puppet.pref
Package: puppet puppet-common puppetmaster-passenger
Pin: version 3.8*
Pin-Priority: 501
Change the /etc/puppet/puppet.conf configuration file as follows(As you see server directive define the master server and certname directive define ubuntu agent common name):
[main] logdir = /var/log/puppet runinterval = 10 rundir = /var/run/puppet ssldir = $vardir/ssl
[agent] classfile = $vardir/classes.txt localconfig = $vardir/localconfig server = pupmaster.unixmen.com certname = pupnode6.unixmen.com
Change the following line in the /etc/default/puppet file as following. This will start the puppet automatically after system reboot:
START=yes
Start puppet agent:
root@pupnode6:~# service puppet start
Look at the agent fingerprint:
root@pupnode6:~# puppet agent --fingerprint (SHA256) F0:43:70:C6:9C:99:43:8F:46:50:37:DD:C1:51:B4:55:1F:FE:73:D1:0C:3B:FD:1D:C0:AD:E4:D3:38:3D:9B:FA
