<span style="font-family: "georgia" , "times new roman" , serif;">Now we should have npm installed.

<span style="font-family: "georgia" , "times new roman" , serif;">The next step is to install nginx. Nginx installation is pretty easy and straight forward:</span></div>
<pre style="background-color: whitesmoke; border-radius: 4px; border: 1px solid rgb(204, 204, 204); box-sizing: border-box; color: #333333; font-family: Menlo, Monaco, Consolas, 'Courier New', monospace; font-size: 14px; line-height: 1.42857; margin-bottom: 10.5px; overflow: auto; padding: 10px; word-break: break-all; word-wrap: break-word;"><code style="background-color: transparent; border-radius: 0px; box-sizing: border-box; color: inherit; font-family: Menlo, Monaco, Consolas, 'Courier New', monospace; font-size: inherit; padding: 0px; white-space: pre-wrap;"># sudo apt-get install nginx
</code></pre>
<div style="background-color: #fdfdfd; box-sizing: border-box; font-size: 18px; line-height: 28px; margin-bottom: 10.5px;">
<span style="font-family: "georgia" , "times new roman" , serif;">That’s it, nginx is installed. Now we need to configure it. First, we change to nginx directory and remove the default configuration file and create a new one:</span></div>
<pre style="background-color: whitesmoke; border-radius: 4px; border: 1px solid rgb(204, 204, 204); box-sizing: border-box; color: #333333; font-family: Menlo, Monaco, Consolas, 'Courier New', monospace; font-size: 14px; line-height: 1.42857; margin-bottom: 10.5px; overflow: auto; padding: 10px; word-break: break-all; word-wrap: break-word;"><code style="background-color: transparent; border-radius: 0px; box-sizing: border-box; color: inherit; font-family: Menlo, Monaco, Consolas, 'Courier New', monospace; font-size: inherit; padding: 0px; white-space: pre-wrap;"># cd /etc/nginx/
# rm sites-enabled/default
# cd sites-available
# touch ghost
</code></pre>
<div style="background-color: #fdfdfd; box-sizing: border-box; font-size: 18px; line-height: 28px; margin-bottom: 10.5px;">
<span style="font-family: "georgia" , "times new roman" , serif;">Then, we need to open <code style="background-color: #f9f2f4; border-radius: 4px; box-sizing: border-box; font-size: 16.2px; padding: 2px 4px;"><span style="color: red;">/etc/nginx/sites-available/ghost</span></code> in our favorite editor, and the paste the following content inside:</span></div>
<pre style="background-color: whitesmoke; border-radius: 4px; border: 1px solid rgb(204, 204, 204); box-sizing: border-box; color: #333333; font-family: Menlo, Monaco, Consolas, 'Courier New', monospace; font-size: 14px; line-height: 1.42857; margin-bottom: 10.5px; overflow: auto; padding: 10px; word-break: break-all; word-wrap: break-word;"><code style="background-color: transparent; border-radius: 0px; box-sizing: border-box; color: inherit; font-family: Menlo, Monaco, Consolas, 'Courier New', monospace; font-size: inherit; padding: 0px; white-space: pre-wrap;">server {
    listen 0.0.0.0:80;

    }
}
</code></pre>
<div style="background-color: #fdfdfd; box-sizing: border-box; font-size: 18px; line-height: 28px; margin-bottom: 10.5px;">
<span style="font-family: "georgia" , "times new roman" , serif;">Next, we need to create a symbolic link to activate the configuration.</span></div>
<pre style="background-color: whitesmoke; border-radius: 4px; border: 1px solid rgb(204, 204, 204); box-sizing: border-box; color: #333333; font-family: Menlo, Monaco, Consolas, 'Courier New', monospace; font-size: 14px; line-height: 1.42857; margin-bottom: 10.5px; overflow: auto; padding: 10px; word-break: break-all; word-wrap: break-word;"><code style="background-color: transparent; border-radius: 0px; box-sizing: border-box; color: inherit; font-family: Menlo, Monaco, Consolas, 'Courier New', monospace; font-size: inherit; padding: 0px; white-space: pre-wrap;"># ln -s /etc/nginx/sites-available/ghost /etc/nginx/sites-enabled/ghost
</code></pre>
<div style="background-color: #fdfdfd; box-sizing: border-box; font-size: 18px; line-height: 28px; margin-bottom: 10.5px;">
<span style="font-family: "georgia" , "times new roman" , serif;">If we restart nginx and start ghost again, we should get Ghost welcome page in our browser. If that is the case, we are done with the installation. The last thing we need to do is to make us able to start/stop the Ghost service like any other server on Ubuntu, using service start and service stop commands. In order to do that we need to create new file in <code style="background-color: #f9f2f4; border-radius: 4px; box-sizing: border-box; font-size: 16.2px; padding: 2px 4px;"><span style="color: red;">/etc/init</span></code> directory.</span></div>

<span style="font-family: "georgia" , "times new roman" , serif;">That concludes the configuration. Now we have fully functional ghost server that will start automatically when system boots up. We can enjoy our blogging on a beautifully designed platform dedicated to that.</span></div>

Using Vagrant, developers and sysadmins can create any virtual environment instantly. Vagrant is extremely simple to use and configure.</div>
<div style="background-color: white; color: #111111; font-family: Georgia, 'Times New Roman', Times, serif; font-size: 16px; line-height: 26px; margin-bottom: 26px; padding: 0px; word-wrap: break-word;">
Vagrant acts as central configuration repository for managing and deploying multiple reproducible virtual environments from a canned OS image with same configuration.<br />
<span id="more-16756" style="margin: 0px; padding: 0px; word-wrap: break-word;"></span></div>
<h3 style="background-color: white; font-family: Georgia, 'Times New Roman', Times, serif; font-size: 1.286em; font-weight: normal; line-height: 1.222em; margin: 1.833em 0px 0.611em; padding: 0px; word-wrap: break-word;">
<span style="color: #0b5394;">1. Install Vagrant</span></h3>
<div style="background-color: white; color: #111111; font-family: Georgia, 'Times New Roman', Times, serif; font-size: 16px; line-height: 26px; margin-bottom: 26px; padding: 0px; word-wrap: break-word;">
First, download the vagrant binaries for your OS from <a href="http://www.vagrantup.com/" style="color: #dd0000; margin: 0px; padding: 0px; word-wrap: break-word;">VagrantUp</a>.</div>
<div style="background-color: white; color: #111111; font-family: Georgia, 'Times New Roman', Times, serif; font-size: 16px; line-height: 26px; margin-bottom: 26px; padding: 0px; word-wrap: break-word;">
Currently it is available for MacOS, Windows, <a href="http://www.hackthesec.co.in/search/label/Debian" target="_blank">Debian </a>and <a href="http://www.hackthesec.co.in/search/label/Centos" target="_blank">CentOS</a>.</div>
<div style="background-color: white; color: #111111; font-family: Georgia, 'Times New Roman', Times, serif; font-size: 16px; line-height: 26px; margin-bottom: 26px; padding: 0px; word-wrap: break-word;">
For this tutorial, we downloaded the 64bit rpm for <a href="http://www.hackthesec.co.in/search/label/centos7" target="_blank">centos</a>.</div>

Please note that vagrant is available on windows as well which means you can download and install vagrant and virtualbox on your windows machine and then run the vagrant commands to quickly build any available vagrant OS’es for your testing.</div>
<div style="background-color: white; color: #111111; font-family: Georgia, 'Times New Roman', Times, serif; font-size: 16px; line-height: 26px; margin-bottom: 26px; padding: 0px; word-wrap: break-word;">
Install the downloaded file on your system using your systems appropriate package installer. Since i am installing this on CentOS.</div>

<span style="color: #0b5394; font-size: large;">2. Add a Vagrant Box</span></h3>
<div style="background-color: white; color: #111111; font-family: Georgia, 'Times New Roman', Times, serif; font-size: 16px; line-height: 26px; margin-bottom: 26px; padding: 0px; word-wrap: break-word;">
The next step is to run “vagrant box add” command. In this example, I am using one of the predefined catalogs available on HashiCorp’s Atlas box catalog. This catalog has <a href="http://www.hackthesec.co.in/2016/01/how-to-install-linux-apache-mysql-and.html" target="_blank">LAMP </a>stack already configured on it.</div>
<pre style="background: none 0px 0px repeat scroll rgb(60, 60, 60); border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="font-size: medium;"><span style="line-height: 15.6px;"><span style="color: white;"># vagrant box add smallhadroncollider/centos-6.4-lamp

Verify that the vagrant box is successfully added using the following command. This will display all the vagrant boxes that are installed on our system. Currently we have only one box installed.</div>
<pre style="background: none 0px 0px repeat scroll rgb(60, 60, 60); border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="font-size: medium;"><span style="line-height: 15.6px;"><span style="color: white;"># vagrant box list

<span style="color: #0b5394; font-size: large;">3. Initialize Vagrant Box</span></h3>
<div style="background-color: white; color: #111111; font-family: Georgia, 'Times New Roman', Times, serif; font-size: 16px; line-height: 26px; margin-bottom: 26px; padding: 0px; word-wrap: break-word;">
Now we are ready to initialize the new Vagrant environment by creating a vagrant file. vagrant status command displays the currently initialized vagrant environments. In this case since we do not have any machines initialized yet, vagrant status gives the below output.</div>
<pre style="background: none 0px 0px repeat scroll rgb(60, 60, 60); border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="font-size: medium;"><span style="line-height: 15.6px;"><span style="color: lime;"># vagrant status

</span><span style="color: white;">A Vagrant environment or target machine is required to run this
command. Run `vagrant init` to create a new Vagrant environment. Or,
get an ID of a target machine from `vagrant global-status` to run
this command on. A final option is to change to a directory with a
Vagrantfile and to try again.</span></span></span></pre>
<div style="background-color: white; color: #111111; font-family: Georgia, 'Times New Roman', Times, serif; font-size: 16px; line-height: 26px; margin-bottom: 26px; padding: 0px; word-wrap: break-word;">
Now we can create a new directory and initialize the vagrant environment that we just downloaded, this will place a plain vagrantfile in the current working directory. You can change many of settings in this file, we can change things such as network configuration, shared folders, and puppet and chef details.</div>
<div style="background-color: white; color: #111111; font-family: Georgia, 'Times New Roman', Times, serif; font-size: 16px; line-height: 26px; margin-bottom: 26px; padding: 0px; word-wrap: break-word;">
Just be aware a box restart will likely be required before changes take effect.</div>
<div style="background-color: white; color: #111111; font-family: Georgia, 'Times New Roman', Times, serif; font-size: 16px; line-height: 26px; margin-bottom: 26px; padding: 0px; word-wrap: break-word;">
To learn more about configuration inside the vagrant file, you can refer the<a href="https://docs.vagrantup.com/v2/vagrantfile/version.html" style="color: #dd0000; margin: 0px; padding: 0px; word-wrap: break-word;">vagrant documentation</a>.</div>
<pre style="background: none 0px 0px repeat scroll rgb(60, 60, 60); border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="font-size: medium;"><span style="line-height: 15.6px;"><span style="color: lime;"># mkdir centos-6.4-lamp
</span><span style="color: white;">
# cd centos-6.4-lamp

# vagrant init smallhadroncollider/centos-6.4-lamp
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
</span><span style="color: lime;">`vagrantup.com` for more information on using Vagrant.</span></span></span></pre>

After you initialize vagrant box, you’ll see that it has created the following file under the current directory.</div>
<pre style="background: none 0px 0px repeat scroll rgb(60, 60, 60); border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="font-size: medium;"><span style="line-height: 15.6px;"><span style="color: white;"># ls -ltr

<div style="background-color: white; color: #111111; font-family: Georgia, 'Times New Roman', Times, serif; font-size: 16px; line-height: 26px; margin-bottom: 26px; padding: 0px; word-wrap: break-word;">
Now if you to try to bring up the vagrant machine, you will see the below error. This is because the provider has not been installed yet on the machine. The provider can be usually Oracle Virtualbox, VMWARE, Hyper-V. Once you choose the provider, depending on OS platform install the respective rpm on the machine.</div>
<pre style="background: none 0px 0px repeat scroll rgb(60, 60, 60); border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="font-size: medium;"><span style="line-height: 15.6px;"><span style="color: white;"># vagrant up

No usable default provider could be found for your system.
Vagrant relies on interactions with 3rd party systems, known as
"providers", to provide Vagrant with resources to run development
</span><span style="color: lime;">environments. Examples are VirtualBox, VMware, Hyper-V.
The easiest solution to this message is to install VirtualBox, which
</span><span style="color: white;">is available for free on all major platforms.

If you believe you already have a provider available, make sure it
is properly installed and configured. You can see more details about
why a particular provider isn't working by forcing usage with
</span><span style="color: lime;">`vagrant up --provider=PROVIDER`, which should give you a more specific
</span><span style="color: white;">error message for that particular provider.</span></span></span></pre>

Note: In my case, I have downloaded and installed Oracle Virtualbox. You need to have one of the virtualization provider installed on your machine for this to work. </div>

Once a provider (Oracle virtualbox, VMWare, etc.) is installed, try to bring up the virtual environment using “vagrant up” as shown below, you can also setup your public network and any other software packages needs to be included or any other configurations in the vagrant file and bring up the virtual machine.</div>
