Installation on OSX
Install Vagrant, librarian-puppet and bundler.
Vagrant (http://vagrantup.com)
librarian-puppet (http://librarian-puppet.com/)
bundler (http://bundler.io/)
Clone the git repository to local disk
git clone https://github.com/SydOps/challenge.git
Install all required gems
bundle install
Install all Puppet modules with Puppet Librarian
librarian-puppet install
you can ignore below error message:
Invalid module name 'apache', you should qualify it with 'ORGANIZATION-apache' for resolution to work correctly
Invalid module name 'haproxy', you should qualify it with 'ORGANIZATION-haproxy' for resolution to work correctly
Start all the vms with Vagrant
vagrant up (or vagrant up web01 ; vagrant up web02; vagrant up haproxy)
( Notes: If you find some services don't run properly, run vagrant provision BOXNAME again, it will fix this issue)
Test the load balancer from your favorite web browser
http://192.168.50.54
Keep refresh, you should see the server name keep changing between web01.example.com and web02.example.com
If you need add more webservers under haproxy, for example, add two more web servers.
edit manifests/vagrant.pp file, you can add more IPs, or remove some IPs.
switch
$webserver = ['192.168.50.50','192.168.50.52']
to
$webserver = ['192.168.50.50','192.168.50.52', '192.168.50.56', '192.168.50.58']
add more boxes in Vagrantfile
config.vm.define :web03 do |config|
config.vm.host_name = "web03.example.com"
config.vm.network :private_network, ip: "192.168.50.56"
end
config.vm.define :web04 do |config|
config.vm.host_name = "web04.example.com"
config.vm.network :private_network, ip: "192.168.50.58"
end
No need run librarian-puppet install this time. Because there is no change in puppet modules.
start new web servers and provision haproxy server.
vagrant up web03; vagrant up web04; vagrant provision haproxy
Then you should see four webservers in haproxy server control
