How to Install Apache Tomcat on Amazon Web Services EC2
As a data scientist or software engineer, the necessity of setting up a server environment is a common requirement. Apache Tomcat, a Java Servlet container developed by the Apache Software Foundation, is a popular choice for deploying Java applications. In this guide, we’ll cover the steps to install Apache Tomcat on an Amazon Web Services (AWS) EC2 instance.
Prerequisites
Before starting, ensure that you have:
- An AWS account.
- Basic knowledge of working with the AWS Management Console.
Step 1: Launch an EC2 Instance
Firstly, you’ll need to launch an EC2 instance. Log into your AWS Management Console, navigate to the EC2 dashboard, and click on ‘Launch Instance’. For this guide, we’ll select the ‘Ubuntu Server 18.04 LTS’ AMI.
Step 2: Connect to Your EC2 Instance
Using an SSH client, connect to your EC2 instance. If you’re using Windows, PuTTY is a good option. If you’re on a Mac or Linux system, simply use the terminal.
Step3: Update Your Instance
Once connected, it’s a good practice to update the instance. Use the following commands:
sudo apt-get update
sudo apt-get upgrade
Step 4: Install Java
Apache Tomcat requires Java, so we’ll install the OpenJDK package:
sudo apt-get install default-jdk
Confirm the installation by checking the Java version:
java -version
Step 5: Download and Install Tomcat
Next, we download Apache Tomcat. At the time of writing, the latest version is Tomcat 9. Use wget to download it:
wget https://downloads.apache.org/tomcat/tomcat-9/v9.0.45/bin/apache-tomcat-9.0.45.tar.gz
Extract the package using the tar command:
tar xvf apache-tomcat-9.0.45.tar.gz
Move it to the /opt directory:
sudo mv apache-tomcat-9.0.45 /opt/tomcat
Step 6: Configure Environment Variables
Set the CATALINA_HOME environment variable to point to the Tomcat installation directory:
echo "export CATALINA_HOME=\"/opt/tomcat\"" >> ~/.bashrc
source ~/.bashrc
Step 7: Start Tomcat
Navigate to the bin directory in the Tomcat folder and execute the startup script:
cd /opt/tomcat/bin
./startup.sh
If the Tomcat server starts successfully, you should see a message similar to ‘Tomcat started’.
Step 8: Access Tomcat
Open a web browser and access Tomcat by typing http://<your-ec2-ip-address>:8080. Replace <your-ec2-ip-address> with the public IP of your EC2 instance. If everything is set up correctly, you should see the Apache Tomcat home page.
Conclusion
In this guide, we walked through the steps to install Apache Tomcat on an AWS EC2 instance. This setup is a common requirement for many web applications and services, especially those requiring a Java environment. With Apache Tomcat on EC2, you can easily deploy and manage your apps.
Remember, this is a basic setup. For a production environment, consider further steps such as setting up security groups, configuring firewalls, and installing SSL certificates.
