Puppet building notes

I. Introduction

Puppet is a C/S structure software that centrally manages files, packages, servers, cron, user, group, exec (execute shell commands), yumrepo, and other common resources of multiple servers.

 

Ii. puppet Workflow

1. Puppet client collects client information through facter (host name, memory, IP address, system information ......) Concurrently sent to the server

2. The server detects the client host name, and then parses the corresponding node configuration in manifest (syntax detection, pseudo code generation, and pseudo code sending to the client), only parses and modifies the node configuration.

3. The client receives the code and then executes it. Then, the client passes the execution result to the server.

4. The server then writes the execution result of the client to the log.

    

 

Iii. installation and configuration

Puppet server: 192.168.1.10 master.puppet.com

Puppet agent: 192.168.1.11 agent.puppet.com

The Host Name and IP address must be resolved. You can manually modify the hosts file or use DNS resolution.

 

1. Configure the epel Source:

   Rpm-ivh http://mirrors.ustc.edu.cn/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm

2. Operations on puppet server:

   Yum install puppet-server-y

    

   Generate the configuration file:
   

   Puppet master -- genconfig>/etc/puppet. conf

   Touch/etc/puppet/manifests/site. pp

   This file is equivalent to an index file, which records the agent configuration and can also define global variables.

   Example:

   Cat/etc/puppet/manifests/site. pp

   Import 'nodes. PP'

   Import 'nodes/*. PP'

   $ Puppetserver = 'master .puppet.com'

3. Operations on puppet agent:

   Yum install puppet-y

   Vim/etc/puppet. conf

   Add

   Server = master.puppet.com (master host name, which must be pinged, hosts or dns resolution bound)

   Add in agent

   Runinterval = 10 (query interval to master, in seconds)

    

 

Iv. Test

Puppet server is started for the first time:

Puppet master -- verbose -- no-daemonize

 

Puppet agent is started for the first time:

Puppet agent -- server = master.puppet.com -- no-daemonize -- verbose -- noop -- onetime

 

If no authentication is reported, run on the CA server (CA and puppet server are on the same stage ):

Puppet cert -- list displays unauthenticated clients

Puppet cert -- sign agent.puppet.com

 

If the restart command runs normally again, the service is enabled separately.

/Etc/init. d/puppetmaster start

Chkconfig puppetmaster on

 

/Etc/init. d/puppet start

Chkconfig puppet on
