Deploying Node.js App on an AWS EC2 Instance
This guide serves to provide instructions on how one can deploy a NodeJS application on an AWS EC2 Linux instance.
The steps involving creating an AWS EC2 instance are detailed in the following page:
There are several methods in which you can SSH into your EC2 instance
Amazon EC2 Instance Connect offers a streamlined and secure method for establishing connections to Linux instances using SSH. AWS Identity and Access Management (IAM) policies and principals are used to control SSH access. This method effectively bypasses the need of handling and sharing SSH keys, which simplifies key management. Thus, EC2 Instance Connect will be our preferred method of accessing our instance.
When trying to connect to the instance, we are brought directly to this page where we are given different options to connect to the instance.
Once connected, you are brought into a Linux instance where the Github repository resides.
After you SSH into the EC2 instance, you need to change the user to a super user in order to have the necessary permissions by using the command:
sudo su
We install nvm (node version manager) by using the following command:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash
Next you will need to activate nvm with the following command:
. ~/.nvm/nvm.sh
Using nvm, we install Node.js with the below command:
nvm install 16
In order to get the source code of the application from GitHub, you must install Git first. This can be done by using the command:
yum update -y
After installing Git, we clone the repository of our application. In our case, we use the following command:
git clone https://github.uconn.edu/mrd19007/CSESDP32
To install the dependencies, use the below command:
npm install
Once everything is set up and all dependencies are installed, you can run the application with the command:
node index.js
