romangarcia / vagrant-test

OJO!!!

• Acordate de correr todo con SUDO!
• Fijate que las VM puedan verse entre si (VagrantFile, hosts, etc)

Preparar las VMs

1)Instalar Vagrant

vagrant init

3. Modificar el VagrantFile

• Levantar un entorno de N VMs con private-networking
• Elegir un box - Yo elegi CentOS 6.3 minimal desde http://www.vagrantbox.es
• Usar IP estatica para el Master
• Forwardear el puerto del Puppet-Dashboard para accederlo desde la PC host

Ejemplo del script:

SCRIPT VAGRANT PARA PUPPET ----------------------------

-- mode: ruby --

vi: set ft=ruby :

Vagrant.configure("2") do |config|

config.vm.define :master do |master| master.vm.box = "centos63" master.vm.box_url = "https://dl.dropbox.com/u/7225008/Vagrant/CentOS-6.3-x86_64-minimal.box" master.vm.network :private_network, ip: "192.168.50.4" master.vm.network :forwarded_port, host: 3000, guest: 3000 end config.vm.define :agent do |agent| agent.vm.box = "centos63" agent.vm.box_url = "https://dl.dropbox.com/u/7225008/Vagrant/CentOS-6.3-x86_64-minimal.box" end

config.vm.network :forwarded_port, guest: 80, host: 8080

end

SCRIPT VAGRANT PARA PUPPET ----------------------------

vagrant up

Instalar Puppet (MASTER):

(http://docs.puppetlabs.com/guides/installation.html)

vagrant ssh master

2. Agregar repositorio de Puppet sudo rpm -ivh http://yum.puppetlabs.com/el/6/products/i386/puppetlabs-release-6-7.noarch.rpm

3. Instalar Master sudo yum install puppet-server (en el master)

Instalar Puppet (AGENT):

(http://docs.puppetlabs.com/guides/installation.html)

vagrant ssh agent

2. Agregar repositorio de Puppet sudo rpm -ivh http://yum.puppetlabs.com/el/6/products/i386/puppetlabs-release-6-7.noarch.rpm

3. Instalar Agente sudo yum install puppet

Configurar hosts y firmar certificados:

1. Cambiar HOSTNAME (en ambos)

sudo vi /etc/sysconfig/network

HOSTNAME=agent.localdomain (master.localdomain en el master)

sudo vi /etc/hosts

192.168.100.100 master.localdomain 192.168.100.200 agent.localdomain

2. Configurar Puppet (Agent)

sudo vi /etc/puppet/puppet.conf

[agent] report = true pluginsync = true certname = agent.localdomain server = master.localdomain

3. Firmar certificados

a) En el agent:

sudo puppet agent --test --debug

deberian aparecer las siguientes lineas: Info: Creating a new SSL certificate request for agent.localdomain Exiting; no certificate found and waitforcert is disabled

b) En el master, despues de (A):

sudo puppet cert list --all

deberia listarse un "certificate_request" para "agent.localdomain"

sudo puppet cert --sign agent.localdomain

deberia aparecer el "sign" del certificado, y el remove del "certificate_request"

---

!!! En caso de problemas !!!

a) Usar --debug en el AGENT y --no-daemonize --verbose --debug en el MASTER b) Eliminar los certificados generados y los requests (ojo si tenias cert aprobados los vas a perder!)

• AGENT: sudo rm -rf /var/lib/puppet/ssl
• MASTER: sudo puppet cert clean --all c) Fijate si el firewall te deja llegar al master puerto 8140 (ver iptables) d) Asegurate que /etc/hosts este bien e) Asegurate que el comando: "hostname" te devuelve el nombre que esperabas (quiza te falto reiniciar la VM)

Instalar el Dashboard:

Instalar MySQL

sudo yum install mysql-server.x86_64

Crear DB

sudo service mysqld start

sudo mysql -u root

CREATE DATABASE dashboard CHARACTER SET utf8; CREATE USER 'dashboard'@'localhost' IDENTIFIED BY 'dashboard'; GRANT ALL PRIVILEGES ON dashboard.* TO 'dashboard'@'localhost';

Instalar el Dashboard

sudo yum install puppet-dashboard

Configurarlo ( user/password y nombre de base )

sudo vi /usr/share/puppet-dashboard/config/database.yml

Arrancar el server

sudo service puppet-dashboard start

• Configurar MySQL para auto-arranque

sudo /sbin/chkconfig --add mysqld

sudo /sbin/chkconfig mysqld on

• Configurar para reportar al dashboard

sudo vi /etc/puppet/puppet.conf (on each agent)

[agent] report = true

sudo vi /etc/puppet/puppet.conf (on puppet master)

[master] reports = store, http reporturl = http://dashboard.example.com:3000/reports/upload

• Configurar para usar el Dashboard como ENC (External Node Classifier) --- OPCIONAL [master] node_terminus = exec external_nodes = /usr/bin/env PUPPET_DASHBOARD_URL=http://localhost:3000 /opt/puppet-dashboard/bin/external_node

• Configurar el Dashboard y los Workers para auto-arranque

sudo chkconfig puppet-dashboard on

sudo chkconfig puppet-dashboard-workers on

Agregar al final

env RAILS_ENV=production /usr/share/puppet-dashboard/script/delayed_job -p dashboard -n 4 -m start

Reiniciar el Master

sudo service puppetmaster restart

Instalar una VM Windows 2008

• Modificar VagrantFile config.vm.define :winagent do |winagent| winagent.vm.box = "win2008" winagent.vm.box_url = "http://dl.dropbox.com/u/58604/vagrant/win2k8r2-core.box" winagent.vm.guest = :windows winagent.windows.halt_timeout = 15 winagent.winrm.username = "vagrant" winagent.winrm.password = "vagrant"
  winagent.vm.network :private_network, ip: "192.168.50.6" winagent.vm.network :forwarded_port, guest: 5985, host: 5985 end

Iniciar la VM con Virtualbox y asegurarse lo siguiente -Enable WinRM winrm quickconfig -q winrm set winrm/config/winrs @{MaxMemoryPerShellMB="512"} winrm set winrm/config @{MaxTimeoutms="1800000"} winrm set winrm/config/service @{AllowUnencrypted="true"} winrm set winrm/config/service/auth @{Basic="true"} Create a vagrant user, for things to work out of the box username and password should both be "vagrant". Turn off UAC (Msconfig) Disable complex passwords

• Instalar el plugin vagrant-windows

vagrant plugin install vagrant-windows
