Step 1: Requirements

Before you start, guarantee that you have the following requirements set up:

Java Development Kit (JDK) 17 or later: Apache Tomcat requires a JDK to run. You can download the latest version of the JDK from the official Oracle website.
Administrator Access: You will need administrator privileges to install software on your PC.

Step 2: Download Apache Tomcat

Visit the Apache Tomcat official website (https://tomcat.apache.org/download-10.cgi), navigate to the “Downloads” section and select the version you wish to install. For this guide, we are utilizing Apache Tomcat 10.

Pick the Binary Distribution. Under the “Core” section, you will find various distributions. The “32-bit/64-bit Windows Service Installer” is recommended for Windows users, and the “tar.gz” and “zip” files are appropriate for Linux and macOS users.

Download the Installer: Click on the suitable version to download the installer or archive file to your local machine. Download the appropriate package for your operating system.

Step 3: Install Apache Tomcat 10

For Windows Users

Run the Installer: Find the downloaded .exe file and double-click it to run the installer.
Follow the Installation Wizard: The wizard will direct you through the installation process. Here are a few key steps:
- Choose Components: Select the components you need to install. The default choice is normally adequate.
- Configure Server Ports: The default port for Tomcat is 8080. You can change this if necessary.
- Select the path of JDK installed on your system.
- Specify Installation Location: Choose the directory where you need to install Tomcat. The default location is like this:
  
  C:\Program Files\Apache Software Foundation\Tomcat 10.1
- Define User Roles: Set up administrator and manager roles by giving usernames and passwords.
Complete Installation: Click “Install” to finish the installation process. Once finished, you can begin the Tomcat server through the Windows Service Manager or from the Start menu.

For Linux and macOS Users

Extract the Archive: Open a terminal and explore to the directory where you downloaded the Tomcat archive. Utilize the accompanying command to extract it:

tar -xvzf apache-tomcat-10.*.tar.gz
Move to Installation Directory: Move the extracted folder to your preferred installation directory, for instance, sudo mv apache-tomcat-10.* /usr/local/tomcat10
Set Environment Variables: To make it simpler to run Tomcat, set environment variables in your .bashrc or .zshrc file:

export CATALINA_HOME=/usr/local/tomcat10
export PATH=$PATH:$CATALINA_HOME/bin

After adding these lines, run source ~/.bashrc or source ~/.zshrc to apply the changes.
Begin Tomcat Server: Utilize the following command to begin the Tomcat server:

$CATALINA_HOME/bin/startup.sh

Step 4: Verify the Installation

To guarantee that Apache Tomcat is installed and running correctly, open a web browser and access the Tomcat welcome page. Enter “http://localhost:8080” in the address bar. Assuming Tomcat is running, you ought to see the Tomcat welcome page.

Step 5: Configure Tomcat (Optional)

For advanced users, you should alter Tomcat settings. Here are a few common configurations:

Server Port Configuration: Modify the server.xml file located in the conf directory to change the default port.
Memory Settings: Change memory settings in the setenv.sh or setenv.bat file to optimize performance.
Security Configuration: Set up user roles and permissions in the tomcat-users.xml file to secure your server.

Conclusion

Whether you’re a novice or an experienced engineer, having Apache Tomcat up and running is a crucial step in developing and deploying Java web applications.
