1. Choose a Suitable VPS Plan
Ensure your VPS supports your preferred OS, such as Ubuntu, CentOS, or Debian. For development purposes, choose a plan with at least 2-4 GB of RAM, adequate CPU power, and sufficient storage (50-100 GB).
2. Connect to Your VPS
SSH Access: Use SSH to connect to your VPS. Open your terminal and enter
3. Update Your System
Upgrade Packages: Make sure all your system packages are up to date

sudo yum update -y # For CentOS
4. Install Java
Install OpenJDK: OpenJDK is a popular choice for Java development. Install it using your package manager.
sudo apt install openjdk-11-jdk -y # For Debian/Ubuntu
sudo yum install java-11-openjdk-devel -y # For CentOS
5. Install an Integrated Development Environment (IDE)
Remote Access IDE: While many developers use local IDEs, you can also install a web-based IDE like Eclipse Che or Theia for remote development.
Example: Installing Eclipse Che:
curl -L -o chectl https://github.com/eclipse/chectl/releases/download/latest/chectl-linux-x64.tar.gz
tar -xvf chectl-linux-x64.tar.gz -C /usr/local/bin
chectl server:start --platform=docker
6. Set Up Your Development Environment
Environment Variables: Set JAVA_HOME and update PATH:
echo 'export JAVA_HOME=$(dirname $(dirname $(readlink -f $(which java))))' >> ~/.bashrc
echo 'export PATH=$PATH:$JAVA_HOME/bin' >> ~/.bashrc
source ~/.bashrc
7. Install Build Tools
Maven: A popular build automation tool for Java.
sudo apt install maven -y # For Debian/Ubuntu
sudo yum install maven -y # For CentOS
Gradle: Another build automation tool.
sudo apt install gradle -y # For Debian/Ubuntu
sudo yum install gradle -y # For CentOS
8. Set Up Version Control
Git: Install Git for version control.
sudo apt install git -y # For Debian/Ubuntu

git config --global user.email 'your.email@example.com'
9. Install Application Server
Apache Tomcat: A widely used application server for running Java applications.
sudo apt install tomcat9 -y # For Debian/Ubuntu
sudo yum install tomcat -y # For CentOS
10. Deploy Your Java Application
Upload Application: Transfer your .war file to the Tomcat webapps directory.
scp your_application.war username@your_vps_ip:/var/lib/tomcat9/webapps/
Start Tomcat: Ensure Tomcat is running.
sudo systemctl start tomcat9 # For Debian/Ubuntu
sudo systemctl start tomcat # For CentOS
11. Access Your Application
Web Browser: Open a web browser and navigate to 'http://your_vps_ip:8080/your_application'.
