Install Sails.js with Apache as a reverse proxy on CentOS 7


Sails.js on CentOSIn today’s article we will install Sails.js on a CentOS 7 VPS with Apache configured as a reverse proxy.

Sails.js is a Javascript framework designed to emulate the familiar MVC pattern of frameworks like Ruby on Rails, but with support for the requirements of modern apps:
data-driven APIs with a scalable, service-oriented architecture.
Sails.js is database agnostic, automatically generates a RESTful JSON API for your app, provides basic security and role-based access control by default, has automatic asset minification and many more.

It’s especially good for building chat, real time dashboards, or multiplayer games; but you can use it for any web application project – top to bottom.

REQUIREMENTS

We will be using our SSD 1 Linux VPS hosting plan for this tutorial.

Log in to your server via SSH:

# ssh root@server_ip

Before starting, enter the command below to check whether you have the proper version of CentOS installed on your machine:

# cat /etc/redhat-release

which should give you the underneath output:

CentOS Linux release 7.2.1511 (Core)

UPDATE THE SYSTEM

Make sure your server is fully up to date:

# yum update

Before installing Sails.js we need to install the Node.js platform. But first, install some much needed tools:

# yum install yum-utils bzip2 bzip2-devel wget curl tar

# yum groupinstall "Development Tools"

Once the install is completed, navigate to your server /opt directory and download the latest (at the time of writing this tutorial) Node.js version with the below two commands:

# cd /opt

# wget http://nodejs.org/dist/v0.12.9/node-v0.12.9.tar.gz

Unpack the archive:

# tar -xzf node-v0.12.9.tar.gz

Enter the unpacked directory:

# cd node-v0.12.9

Next, configure NodeJS sources by setting the –prefix flag to /usr/local, so that NodeJS will be installed in this location and will be usable to all users on the Linux VPS:

# ./configure --prefix=/usr/local

Once the configuration is completed, compile and install NodeJS using the following commands:

# make

# make install

After the installation is finished, check the Node.js version with:

# node --version

Which should give you the following output:

# v0.12.9

Now you can install Sails.js. In your command line interface type:

# npm -g install sails

Create a new Sails project:

# cd && sails new yourprojectName

Start the server and make it work in the background using:

# cd yourprojectName && sails lift &

By default the server is listening on 127.0.0.1:1337

Last but not least you need to configure Apache as a reverse proxy for your domain. With your favorite text editor open a new file. We are using vim:

# vim /etc/httpd/conf.d/your_domain.conf

Once the file is opened, paste the below lines:

<VirtualHost *:80>
ServerName your_domain.com
ServerAlias www.your_domain.com

ProxyRequests Off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>

ProxyPass / http://your_domain.com:1337/
ProxyPassReverse / http://your_domain.com:1337/
<Location />
Order allow,deny
Allow from all
</Location>
</VirtualHost>

Don’t forget to replace your_domain.com with your actual domain. Save and close the file. Restart Apache for the changes to take effect:

# service httpd restart

Congratulations, you have successfully installed Sails.js and configured Apache as a reverse proxy.

Your next step is to open your favorite web browser and navigate to http://your_domain.com where you will be welcomed by a page as shown in the picture below:
