|
|
|
```
|
|
git clone https://github.com/hpcloud-mon/mon-vagrant

## Setup Vagrant
|
|
|
|
### Install Vagrant
|
|
Assumes you have home homebrew installed, if not download and install VirtualBox and Vagrant from their websites then continue with Setup Berkshelf.
|
|
|
|
```
|
|
brew tap phinze/cask
|
|
brew install brew-cask
|
|
brew cask install virtualbox
|
|
brew cask install vagrant
|
|
```
|
|
|
|
### Setup Berkshelf
|
|
```
|
|
vagrant plugin install vagrant-berkshelf
|
|
gem install berkshelf
|
|
```
|
|
|
|
# Using mini-mon
|
|
|
|
- Your home dir is synced to `/vagrant_home` on each vm
|
|
- Vms created
|
|
- `api` at `192.168.10.4`
|
|
- `kafka` at `192.168.10.10` - mon-notification runs on this box also
|
|
- `mysql` at `192.168.10.6`
|
|
- `persister` at `192.168.10.12`
|
|
- `thresh` at `192.168.10.14`
|
|
- `vertica` at `192.168.10.8`
|
|
- The management console is at https://192.168.10.8:5450
|
|
- Run `vagrant help` for more info
|
|
- Run `vagrant ssh <vm name>` to login to a particular vm
|
|
- Can also run `ssh vagrant@<ip address>` to login
|
|
- password is `vagrant`
|
|
|
|
## Start mini-mon
|
|
From within the `mini-mon` directory, to start all the vms run:
|
|
```
|
|
bin/vup
|
|
```
|
|
The standard vagrant commands can also be used, the vup script just starts things up in a dependency order using parallel startup.
|
|
|
|
## Halt mini-mon
|
|
In some cases halting mini-mon can result in certain vms being left in an odd state, to avoid this a script has been made to halt boxes in the
|
|
correct order
|
|
```
|
|
bin/vhalt
|
|
```
|
|
|
|
## Updating a VM
|
|
When someone updates the config for a vm this process should allow you to bring up an updated vm.
|
|
- `git pull`
|
|
- `berks update`
|
|
- `vagrant destroy vm` - Where vm is the name of the vm being updated, for example 'vertica'
|
|
- `vagrant up vm`
|
|
|
|
## Improving Provisioning Speed
|
|
The slowest part of the provisioning process is the downloading of deb packages. To speed this up a local apt-cacher-ng can be used.
|
|
To install on a mac
|
|
```
|
|
brew install apt-cacher-ng
|
|
```
|
|
Run `apt-cacher-ng -c /usr/local/etc/apt-cacher-ng/` or optionally follow the instructions from brew to start up the cache automatically.
|
|
That is all that is needed from now on the cache will be used.
|
|
|
|
A report from the cache is found at http://localhost:3142/acng-report.html
|
|
|
|
## Cookbook Development
|
|
|
|
To develop cookbook changes with Vagrant:
|
|
- Edit Berksfile changing the appropriate cookbook line to a local path, ie `cookbook 'zookeeper', path: '/Users/kuhlmant/src/mon/cookbooks/zookeeper'`
|
|
- Edit your local cookbook as needed.
|
|
- run 'berks update <cookbook_name>'
|
|
- If the vagrant vm is already up run 'vagrant provision' if not run 'Vagrant up'
|
|
- When finish testing commit and upload your cookbook as normal but don't forget to bump the cookbook version in the metadata.rb.
|

# Running hLinux as the base OS
|
|
hLinux can be installed and run as the base OS for all the vms defined in mini-mon. To this comment/uncomment the appropriate lines in the Vagrantfile.
|
|
Also switch to the proper base apt repos in recipes/default.rb. There are a couple of minor problem which would slow down development and are why at
|
|
this point hLinux has not been turned on by default:
|
|
- The vboxsf filesystem driver is not working correctly in hLinux, this prevents home directory syncing.
|
|
- Slow network performance of the hLinux vbox image makes some tasks annoying.
|
|
|
|
## Creating a new hLinux box
|
|
The [hLinux](http://hlinux-home.usa.hp.com/wiki/index.php/Main_Page) box used in mini-mon is created via [packer](http://www.packer.io/), config is in
|
|
the templates directory.
|
|
|
|
- Install packer
|
|
- `brew tap homebrew/binary`
|
|
- `brew install packer`
|
|
- Run packer
|
|
- `cd templates`
|
|
- `packer build hlinux.json`
|
|
- From the mini-mon directory run `vagrant box add hlinux templates/packer_virtualbox-iso_virtualbox.box`
|
|
- If you have an existing hLinux box you man need to first remove it `vagrant box remove hlinux`
|
|
- Also upload to a server for others to download.
