Puppet installation and deployment

Puppet installation and deployment

Environment: CoentOS 5.8 x86_64, selinux, and iptables have disabled host planning:

 
 

  
  
server.laoguang.me  192.168.12.117 
  
  
client.laoguang.me  192.168.12.161 
 
 

1. Preparations before installation are required.1.1 hostname and IP ing write/etc/hosts

 
 

  
  
echo " 
  
  
192.168.12.117  server.laoguang.me  server 
  
  
192.168.12.161  client.laoguang.me  client 
  
  
" >> /etc/hosts 
  
  
 
  
  
scp /etc/hosts client:/etc/ 
 
 

1.2 synchronization time, which is very important

 
 

  
  
yum -y install ntp 
  
  
ntpdate ntp.api.bz 
 
 

Ii. Install puppet2.1 software preparation

 
 

  
  
Factor ## factor is a built-in tool provided by puppet to obtain client variables.
  
  
Wget http://puppetlabs.com/downloads/facter/facter-1.6.7.tar.gz
  
  
Puppet
  
  
Wget http://puppetlabs.com/downloads/puppet/puppet-2.7.13.tar.gz
 
 

2.2 install ruby. Puppet is written in ruby.

 
 

  
  
yum -y install ruby 
 
 

2.3 install facter

 
 

  
  
tar zxvf facter-1.6.4.tar.gz 
  
  
cd facter-1.6.4 
  
  
ruby install.rb 
 
 

2.3 install Puppet

 
 

  
  
cd .. 
  
  
tar zxvf puppet-2.7.6.tar.gz 
  
  
cd puppet-2.7.6 
  
  
ruby install.rb 
 
 

2.4 Add puppet users

 
 

  
  
useradd -s /sbin/nologin puppet 
 
 

2.5 copy the required configuration file.

 
 

  
  
cd conf/redhat/ 
  
  
cp puppet.conf /etc/puppet/ 
  
  
cp fileserver.conf /etc/puppet/ 
  
  
cp logrotate /etc/puppet/ 
  
  
cp server.sysconfig /etc/sysconfig/puppetmaster 
  
  
cp server.init /etc/init.d/puppetmaster 
 
 

Iii. Configuration and Testing3.1 modify the configuration file server without modifying the client:

 
 

  
  
Vim/etc/puppet. conf
  
  
 
  
  
[Main]
  
  
Logdir =/var/log/puppet
  
  
Rundir =/var/run/puppet
  
  
Ssldir = $ vardir/ssl
  
  
[Agent]
  
  
Classfile = $ vardir/classes.txt
  
  
Serverserver = server. laoguang. me # define server
  
  
Report = true # status report
  
  
Runinterval = 180 # client Update Interval
  
  
Localconfig = $ vardir/localconfig
 
 

3.2 Test the server front-end startup to facilitate viewing logs:

 
 

  
  
puppet master --no-daemonize --debug --verbose 
 
 

Client Verification:

 
 

  
  
puppetd --test --server server.laoguang.me  
 
 

Server to check whether a signature request is received:

 
 

  
  
puppet cert --list  
  
  
  client.laoguang.me (xx:xx:xx:xx:xx:xx:--) 
 
 

The server signs the client

 
 

  
  
puppet cert -s client.laoguang.me 
 
 

The client obtains the server's configuration for the client and applies

 
 

  
  
pupppet --test --server server.laoguang.me 
 
 

Deployment is complete! Problems: 1. no puppet is added. server startup fails. 2. no synchronization time, no signature is allowed. After the synchronization time, delete all files under/var/lib/puppet/ssl/and verify again. The installation is relatively simple, the specific configuration in the future will be very complicated. Let's make it easy to update: deploy the puppet web Management page puppet-dashboard 4. Deploy the dashboard4.1 software preparation 1. ruby-enterprise-1.8.7 # compatibility issues with the 1.8.5 System

 
 

  
  
wget http://rubyenterpriseedition.googlecode.com/files/ruby-enterprise-1.8.7-2012.02.tar.gz 
 
 

2. readline-devel # ruby dependency, which is not included in my source

 
 

  
  
Wget ftp://rpmfind.net/linux/centos/5.9/ OS /i386/CentOS/readline-devel-5.1-3.el5.i386.rpm # x64 available
 
 

3. libtermcap-devel # readline-devel dependency

 
 

  
  
wget ftp://rpmfind.net/linux/centos/5.8/os/x86_64/CentOS/libtermcap-devel-2.0.8-46.1.x86_64.rpm 
 
 

4. puppet-dashboard-1.2.7 # what we want to install

 
 

  
  
wget http://downloads.puppetlabs.com/dashboard/puppet-dashboard-1.2.7.tar.gz 
 
 

4.2 install ruby-enterprise-1.87 first install the dependency package

 
 

  
  
rpm -ivh libtermcap-devel-2.0.8-46.1.x86_64.rpm readline-devel-5.1-3.el5.i386.rpm 
 
 

Unzip and install ruby

 
 

  
  
Tar xvf ruby-enterprise-1.8.7-2012.02.tar.gz

Database: dashboard
  
  
Username: dashboard
  
  
Password: "redhat"
  
  
Encoding: utf8
  
  
Adapter: mysql # If mysql-server is on another host, you can add host: Segment
 
 

Generate table

 
 

  
  
Rake RAILS_ENV = production db: create # This may cause an error. The gem and rails versions may be incompatible,
 
 

I chose to downgrade the gem.

 
 

  
  
Gem update -- system 1.5.3 # downgrade gem
 
 

Re-Execute

 
 

  
  
Rake RAILS_ENV = production db: create # Run in/usr/local/puppet-dashboard
  
  
Rake RAILS_ENV = production db: migrate
 
 

If the execution is normal, congratulations on starting dashboard
