Deploy Spring Boot Application with Nginx Ubuntu on AWS Beanstalk

• The Spring Framework is an application framework and inversion of control container for the Java platform. The framework's core features can be used by any Java application, but there are extensions for building web applications on top of the Java EE platform.

• Nginx, stylized as NGINX, nginx or NginX, is a web server that can also be used as a reverse proxy, load balancer, mail proxy and HTTP cache. The software was created by Igor Sysoev and publicly released in 2004. Nginx is free and open-source software, released under the terms of the 2-clause BSD license.

• Amazon Web Services is a subsidiary of Amazon providing on-demand cloud computing platforms and APIs to individuals, companies, and governments, on a metered pay-as-you-go basis.

Requirements

• Java Version 8
• Ubuntu server
• AWS Server

Getting Started

Update your server with the following command:

apt-get update -y
apt-get upgrade -y

Install Java and check version

apt-get install openjdk-8-jdk -y
java -version

You should see the following output:

java version "1.8.0_221"
Java(TM) SE Runtime Environment (build 1.8.0_221-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.221-b11, mixed mode)

Install Spring Boot CLI

Now install Spring Boot CLI and Other build tools

# curl -s https://get.sdkman.io | bash
# source "/root/.sdkman/bin/sdkman-init.sh"
# sdk install springboot
# spring version
# sdk install gradle 4.5.1

Build a Jar File with Gradle

# spring init --build=gradle --dependencies=web --name=hello hello-world
Using service at https://start.spring.io
Project extracted to '/root/hello-world'
# spring init --list
# cd hello-world
# nano src/main/java/com/example/helloworld/HelloApplication.java
# ./gradlew build
# java -jar build/libs/hello-world-0.0.1-SNAPSHOT.jar
# gradle bootRun

Create a Systemd Service File for Spring Boot

# nano /etc/systemd/system/helloworld.service
# systemctl daemon-reload
# systemctl start helloworld
# systemctl enable helloworld
# systemctl status helloworld

Configure Nginx as a Reverse Proxy

# apt-get install nginx -y
# nano /etc/nginx/conf.d/helloworld.conf
# systemctl restart nginx
