First of all set the “yourvagranthostname” in host /etc/hosts, with the the private network ip address that just configured below yourvagranthostname

download centos box file from http://www.vagrantbox.es/

$vagrant box add mylovelybox ~/path-to-box-file/file.box
==> box: Box file was not detected as metadata. Adding it directly...
==> box: Adding box mylovelybox (v0) for provider:
    box: Unpacking necessary files from: file:///Users/MyMac/vagrant_box/CentOS-Ruby.box
$vagrant box list
mylovelybox (virtualbox, 0)
mytrusty  (virtualbox, 0)
$mkdir myproject
$cd myproject
$vagrant init mylovelybox
A Vagrantfile has been placed in this directory. You are now
ready to vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
vagrantup.com for more information on using Vagrant.
$vim Vagrantfile

edit your Vagrantfile to this

Vagrant.configure(2) do |config|
   config.vm.box = "mylovelybox" 
   config.vm.network "forwarded_port", guest: 3000, host: 3000
   #choose random or as your wish ip address for the prvate network
   config.vm.network "private_network", ip: ""
   config.vm.synced_folder "./your-rails-app-project", "/vagrant" 

run your vagrant

There was an error while executing `VBoxManage`, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.

Command: ["startvm", "7b5094ad-75e4-4e75-9100-794569c929c7", "--type", "headless"]

Stderr: VBoxManage: error: Implementation of the USB 2.0 controller not found!
VBoxManage: error: Because the USB 2.0 controller state is part of the saved VM state, the VM cannot be started. To fix this problem, either install the 'Oracle VM VirtualBox Extension Pack' or disable USB 2.0 support in the VM settings.
VBoxManage: error: Note! This error could also mean that an incompatible version of the 'Oracle VM VirtualBox Extension Pack' is installed (VERR_NOT_FOUND)
VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component ConsoleWrap, interface IConsole

oops i think, i forgot something. i should configure my virtualbox first do this so the error will resolved. disable usb!

shutdown the usb port

and dont forget to create host-only network adapter on virtualbox, so we can use our private network that just configured above

add adapter

try run vagrant again

now i am officially in a box. now set the host name. append this to /etc/hosts   yourvagranthostname

because i want to run my thin ruby webserver in nginx server block ( virtual host ) so i should edit the configuration in /etc/nginx/conf.d/whateveryourconfigfile.conf

server {
  listen       80;
  server_name  yourvagranthostname;
  location / {
          proxy_set_header Host $host;
          proxy_set_header X-Real-IP $remote_addr;
          proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
          proxy_set_header X-Forwarded-Proto $scheme;

add new directory called “pids” on your rails project directory

$cd /vagrant
$mkdir -p tmp/pids

now create development.yml in config/thin directory

chdir: "/vagrant"
environment: development
port: 3000
timeout: 30
log: "/etc/nginx/conf.d/log/thin.log"
pid: tmp/pids/thin.pid
max_conns: 1024
max_persistent_conns: 100
require: []
wait: 30
threadpool_size: 20
servers: 1
daemonize: true

then invoke thin. and check it with ps

$thin -e development -C config/thin/development.yml start
Starting server on ...
$ps -ax | grep thin
 6157 ?        Sl     0:08 thin server (
 6170 pts/0    R+     0:00 grep --color=auto thin

Test the nginx configuration and reload my nginx server, dont forget to make sure nginx are run on background

$sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
$sudo nginx -s stop && sudo nginx -s reload && sudo nginx 
$ps -ax | grep nginx
 6262 ?        Ss     0:00 nginx: master process nginx
 6263 ?        S      0:00 nginx: worker process

then call the hostname in browser http://yourvagranthostname/

call vagrant hostname in browser
