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