1. clone git repository - it is public

vagrant up - should bring up vagrant guest machine

3. can ssh into vagrant machine as [email protected] - double check ssh port as vagrant swaps it on various loads
4. adjust location of your private key with below command.

ssh -i /home/sanket-rhythmone/lifeworks/.vagrant/machines/default/virtualbox/private_key -p 2200 [email protected] ansible ssh port config can be found in the lifeworks-inventory file

5. you will need ansible version 2.5.5. preferably inside an ansible virtualenv so that you do not pollute your environment to provisin the server use ansible-playbook module. and call it like this.

ansible-playbook -i lifeworks-inventory site.yml

after ansible provisions the server. nginx will be available on host machine at localhost:1234

downloading Vagrant
also considering using jupyter-notebook to serve a python code interpreter which will have the fizzbuzz test easy to run vagarant will have to port forward jupyter-notebook to host port so that notebook can be accessed wrote fizzbuzz in python using ipython notebook interpreter locally\

def fizzbuzz():
....for i in range(1,101):\
........if i%3==0 and i%5==0:
..........print "fizubuzz"
........elif i%3==0:
..........print "fizz"
........elif i%5==0:
..........print "buzz"
........else:
..........print str(i)\

checked results of fizzbuzz to reasonable depth

tried vagrant up. it fails with plugin conflicting dependecy errors. \ trying vagrant plugin expunge --reinstall "vagrant expunge has been declined" uninstalled and reinstalled vagrant. same results as above.

installing hostmanager pluging, it manages hosts file

vagrant plugin install vagrant-hostmanager

trying vagrant again

1. vagrant up vagrant comes up !!!

default: SSH address: 127.0.0.1:2222 default: SSH username: vagrant default: SSH auth method: private key ==> default: Machine booted and ready! default: Mounting shared folders... default: /vagrant => /home/sanket-rhythmone/lifeworks

trying vagrant ssh default Errors - OpenSSL version mismatch. Built against 1000200f, you have 1000105f

inspecting vagrantbox ssh config info using vagrant ssh-config gives details about the vagrant box, and there is a ssh private key location too.

trying alternative ssh login vagrant ssh using ssh key and 127.0.0.1 port2222 WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! Host key verification failed. remove known host for vagrant ssh-keygen -f "/home/sanket-rhythmone/.ssh/known_hosts" -R "[127.0.0.1]:2222"

now trying ssh again ssh -i /home/sanket-rhythmone/lifeworks/.vagrant/machines/default/virtualbox/private_key -p 2222 [email protected] Welcome to your Scale Factory virtual machine. [vagrant@centos6 ~]$ success loggin into vagrant

Using ansible to collect official nginx role to install onto vagrant box.
nginx role needs various variables to be configured to make installation for CentOS.

Vagrant trouble again. "insecure private key, making new one" then asks for password at login. --solution - vagrant sets up ssh port different each time I do vagrant up. so ssh login command has to be updated each time.

ansible ssh port config can be found in the lifeworks-inventory file

and again - Vagrant cannot forward the specified ports on this VM, since they would collide...Solution - discovered I need to destroy previous running vagrant instances to eliminate this error.

Ansible site.yml is configured to install nginx and run it.

successfully started nginx on vagrant box. port forwarded to localhost:1234. nginx webpage shows up from browser.

successfully added ansible tasks to

1. install required libraries for development
2. python development modules are needed aswell, python-devel.x86_64, lots of errors when installing
3. it was tricky to find and install the right python-pip version because CentOS does not come with python dependencies
4. installed and extracted python setup.py
5. found an older more compatible version of python-pip after much googling https://bootstrap.pypa.io/2.6/get-pip.py
6. for webserver stack installing jupyter-notebook on CentOS would involve compiling and Building the pyzmq. so decided to tackle nginx-uwsgi with python flask
7. currently figuring out an error causing timeout from upstream uwsgi to nginx proxy. proxy_pass looks fine, issue is elsewhere.

uwsgi --socket 127.0.0.1:8080 --protocol=http -w WSGI:app & uwsgi --ini myconf.ini --socket 127.0.0.1:8080 --protocol=http -w WSGI:app &
