How to install LAMP (Apache, MySQL, PHP) stack in Ubuntu 18.0.4?


Pre-requisites:
Pupper master up and running

Watch the steps in YouTube channel:


Login to Puppet Master, follow the below steps:

cd /opt/puppetlabs/puppet/modules
sudo mkdir lamp
cd lamp
sudo mkdir manifests
cd manifests
sudo vi init.pp
Copy the below lines in init.pp

class lamp {
# execute 'apt-get update'
exec { 'apt-update':                    # exec resource named 'apt-update'
  command => '/usr/bin/apt-get update'  # command this resource will run
}

# install apache2 package
package { 'apache2':
  require => Exec['apt-update'],        # require 'apt-update' before installing
  ensure => installed,
}

# ensure apache2 service is running
service { 'apache2':
  ensure => running,
}

# install mysql-server package
package { 'mysql-server':
  require => Exec['apt-update'],        # require 'apt-update' before installing
  ensure => installed,
}

# ensure mysql service is running
service { 'mysql':
  ensure => running,
}

# install php7 package
package { 'php7.2-cli':
  require => Exec['apt-update'],        # require 'apt-update' before installing
  ensure => installed,
}

# ensure info.php file exists
file { '/var/www/html/info.php':
  ensure => file,
  content => '<?php  phpinfo(); ?>',    # phpinfo code
  require => Package['apache2'],        # require 'apache2' package before creating
}
}

sudo vi /etc/puppetlabs/code/environments/production/manifests/site.pp
Add below line of code where node should be your target node where you already approved the certificate. the highlighted below section needs to be changed:

node 'your_target_puppet_agent_node_private_DNS_name' {
 include lamp
 }

Now to login to puppet agent node, execute the below command:
sudo /opt/puppetlabs/bin/puppet agent --test

You should see message like below:

Now make sure Apache is running on the target node by entering the target node(Agent's) public IP address on the browser. You should see Apache home page in the browser.
