Puppet Enterprise Architecture deployment

Puppet Enterprise Architecture deployment

I have been preparing for Puppet. I have read the Puppet document these two days and simulated the deployment scheme of Puppet in the production environment:

Test Machine:
Server: 192.168.3.68
Clinet: 192.168.3.67

Command rules:
Application _ IDC _ location _ IP address _ server system _ Domain Name
192.168.3.67 ppttest_wangsu_bj_192.168.3.67.CentOS.yypuppet.com
192.168.3.68 pptserver_wangsu_bj_192.168.3.68.centos.yypuppet.com

*****
This article focuses on deployment of the puppet architecture. The installation process is not the focus of this Article. Please install it on your own.

Main configuration file:
Root @ pts/2 # cat/etc/puppet. conf
[Main]
Logdir =/var/log/puppet

Rundir =/var/run/puppet

Ssldir = $ vardir/ssl

[Agent]
Classfile = $ vardir/classes.txt

Localconfig = $ vardir/localconfig
Server = pptserver_wangsu_bj_192.168.3.68.centos.yypuppet.com
[Master]
Environments = yydev, yytest, yyprd
[Yydev]
Modulepath = $ confdir/multi-environment/yydev/environment/modules: $ confdir/multi-environment/yydev/application/modules
Manifest = $ confdir/multi-environment/yydev/manifests/site. pp
Fileserverconfig =/etc/puppet/fileserver. conf. yydev
[Yytest]
Modulepath = $ confdir/multi-environment/yytest/environment/modules: $ confdir/multi-environment/yytest/application/modules
Manifest = $ confdir/multi-environment/yytest/manifests/site. pp
Fileserverconfig =/etc/puppet/fileserver. conf. yytest
[Yyprd]
Modulepath = $ confdir/multi-environment/yyprd/environment/modules: $ confdir/multi-environment/yyprd/application/modules
Manifest = $ confdir/multi-environment/yyprd/manifests/site. pp
Fileserverconfig =/etc/puppet/fileserver. conf. yyprd
Why are there two directories, environment and application, in each environment? The environment directory stores the basic environment modules, such as puppet and yum;
The application directory contains application environment modules, such as apache and mysql. Of course, you can also put it in the same directory. If there are many applications, you can split the application. Everything is to facilitate management.


Implementation process:
1: Create a multi-environment directory:
Cd/etc/puppet
Mkdir-p multi-environment/yydev/environment/modules; mkdir-p multi-environment/yydev/application/modules
Mkdir-p multi-environment/yytest/environment/modules; mkdir-p multi-environment/yytest/application/modules
Mkdir-p multi-environment/yyprd/environment/modules; mkdir-p multi-environment/yyprd/application/modules
2: Create a multi-Environment File Server:
Cp/etc/puppet/fileserver. conf {,. yydev}; cp/etc/puppet/fileserver. conf {,. yytest}; cp/etc/puppet/fileserver. conf {,. yyprd}
3: copy existing modules to three environments:
Cp/etc/puppet/modules/ssh/etc/puppet/multi-environment/yydev/environment/modules
Cp/etc/puppet/modules/httpd/etc/puppet/multi-environment/yydev/application/modules
Cp/etc/puppet/modules/ssh/etc/puppet/multi-environment/yytest/environment/modules
Cp/etc/puppet/modules/httpd/etc/puppet/multi-environment/yytest/application/modules
Cp/etc/puppet/modules/ssh/etc/puppet/multi-environment/yyprd/environment/modules
Cp/etc/puppet/modules/httpd/etc/puppet/multi-environment/yyprd/application/modules
