Making Our CI Server into A Vagrant

Now let’s make our CI server into a Vagrant that is provisioned by Puppet. First we need a base box. Since my current theme is using AWS, I will use a CentOS distribution of Linux.

I found a CentOS Jenkins basebox from nrel (which at first glance I took to be RHEL… but not, it’s NREL which stands for National Renewable Energy Laboratory!)

This basebox can be located at this link:
http://nrel.github.io/vagrant-boxes
or Vagrant Cloud: nrel/CentOS-6.5-x86_64

$ vagrant init nrel/CentOS-6.5-x86_64

I modified the Vagrantfile for a custom IP address, just because that’s how I roll. I like to use an IP address and hack my local host file to point to it.

config.vm.network "private_network", ip: "192.168.33.88"

Our CI Server Vagrant box will feature:

Jenkins
PHPUnit
WP-Unit Testing

But first, we have to take care of the home front: the server itself. Let’s whip it into shape.

Clear IP Tables

CentOS has iptables in place to keep the server locked down when you first run it. Down the road, I will refine this to be more nuanced, but for now I’m just going to open all the ports.

exec{'clear_iptables':
command => "/sbin/iptables -F",
}

Install Apache

package { 'httpd':
name => "httpd",
ensure => present,
}

service { "httpd":
ensure => "running",
require => Package["httpd"],
}

Install the Latest WordPress

exec{'download_latest_wordpress':
command => "/usr/bin/wget -q http://wordpress.org/latest.tar.gz -O /var/www/html/latest.tar.gz",
creates => "/var/www/html/latest.tar.gz",
require => Package["httpd"],
before => Exec["unpack_latest.tar.gz"],
}

exec {'unpack_latest.tar.gz':
command => "tar xf /var/www/html/latest.tar.gz",
cwd => "/var/www/html",
path => "/bin",
}

Install Java

Let’s get started with installing Java. Puppet considers the default package manager for CentOS to be yum, so since we know the repo exists in yum, we can do it just this easily.

package { "java-1.6.0-openjdk":
ensure => "installed"
}

Install Jenkins

exec{'download_latest_jenkins_repo':
command => "/usr/bin/wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat/jenkins.repo",
creates => "/etc/yum.repos.d/jenkins.repo",
require => Package["java-1.6.0-openjdk"],
before => Exec["import_jenkins_key"],
}

exec {'import_jenkins_key':
command => "/bin/rpm --import https://jenkins-ci.org/redhat/jenkins-ci.org.key",
cwd => "/home/vagrant",
before => Package["jenkins"]
}

package { "jenkins":
ensure => "installed"
}

service { "jenkins":
ensure => "running",
require => Package["jenkins"],
}

http://pkg.jenkins-ci.org/redhat/

Install PHPUnit

exec{'download_PHP_unit':
command => "/usr/bin/wget -O /usr/bin/phpunit.phar https://phar.phpunit.de/phpunit.phar",
creates => "/usr/bin/phpunit.phar",
before => Exec["run_phpunit_phar_commands"],
}

exec{'run_phpunit_phar_commands':
command => "/bin/chmod +x /usr/bin/phpunit.phar && /bin/mv /usr/bin/phpunit.phar /usr/local/bin/phpunit",
cwd => "/usr/bin",
}

Install mysql

package { "mysql-server":
ensure => "installed",
require => Package["httpd"],
}

service { "mysqld":
enable => true,
ensure => running,
require => Package["mysql-server"],
before => Exec["wait-for-mysqld"]
}

exec {"wait-for-mysqld":
require => Service["mysqld"],
command => "/usr/bin/mysql -u root --password= -e \"create database wp_test_database;grant all on wp_test_database.* to 'wptestuser'@'localhost' identified by 'vagrant';\"",
}

package { "php-mysql":
ensure => "installed",
require => Package["mysql-server"],
}

Install PHP Cli

package { "php-cli":
ensure => "installed",
require => Package["php-mysql"],
}

Install SVN

package { "mod_dav_svn":
ensure => "installed",
require => Package["php-cli"],
}

Install WP Unit Testing

file { "/home/vagrant/svn":
ensure => "directory",
}

file { "/home/vagrant/svn/wordpress-dev":
ensure => "directory",
}

exec {"checkout-svn-wordpress-test":
  command => "/usr/bin/svn co http://develop.svn.wordpress.org/trunk/",
  cwd => "/home/vagrant/svn/wordpress-dev/",
  before => Exec["copy-wp-tests-config-sample"]
}

exec {"copy-wp-tests-config-sample":
  command => "/bin/cp wp-tests-config-sample.php wp-tests-config.php",
  cwd => "/home/vagrant/svn/wordpress-dev/trunk",
  before => Exec["configure-wp-tests-config-sample"]
}

exec {"configure-wp-tests-config-sample":
  command => "/bin/sed -i 's%youremptytestdbnamehere%wp_test_database%g' wp-tests-config.php && sudo sed -i 's%yourusernamehere%wptestuser%g' wp-tests-config.php && sudo sed -i 's%yourpasswordhere%vagrant%g' wp-tests-config.php",
  cwd => "/home/vagrant/svn/wordpress-dev/trunk",
  before => Package["php-xml"]
}

So now we’re done, right?

[vagrant@localhost trunk]$ phpunit
PHP Fatal error:  Class 'DOMDocument' not found in phar:///usr/local/bin/phpunit/phpunit/Util/XML.php on line 146

Not so fast! Unfortunately, our local CentOS install doesn’t quite match our AWS Linux AMI. When I referenced the above error online, I quickly learned that it is the result of not having the php-xml module installed. So we have to add this to our manifest:

package { "php-xml":
  ensure => "installed",
  require => Exec["configure-wp-tests-config-sample"]
}
