    Step-by-Step Guide: Install Tomcat on a Linux System

    Step 1: Preparations

    Before installing Apache Tomcat, ensure that Java is installed on your system. The latest Long-Term Support (LTS) version is OpenJDK 21, released in September 2023.

    Update your package sources:

    Copy<br /> Code 
    

    sudo apt update

    Install the default JDK:

    Copy<br /> Code 
    

    sudo apt install default-jdk

    Verify the Java installation:

    Copy<br /> Code 
    

    java -version

    Step 2: Set Up Tomcat User

    It’s recommended to run Tomcat under a dedicated user. Create a new user named ‘tomcat’:

    Copy<br /> Code 
    

    sudo useradd -r -m -U -d /opt/tomcat -s /bin/false tomcat

    Step 3: Download Tomcat Package

    As of January 2025, the latest stable version of Apache Tomcat is 10.1.x. APACHE TOMCAT

    Download the latest version:

    Copy<br /> Code 
    

    wget https://downloads.apache.org/tomcat/tomcat-10/v10.1.34/bin/apache-tomcat-10.1.34.tar.gz

    Step 4: Install Tomcat on Linux

    Extract the downloaded archive to /opt/tomcat:

    Copy<br /> Code 
    

    sudo mkdir /opt/tomcat
sudo tar xf apache-tomcat-10.1.34.tar.gz -C /opt/tomcat --strip-components=1

    Adjust permissions:

    Copy<br /> Code 
    

    sudo chown -R tomcat: /opt/tomcat
sudo sh -c 'chmod +x /opt/tomcat/bin/*.sh'

    Step 5: Configure Tomcat Service

    Create a systemd service file for Tomcat:

    Copy<br /> Code 
    

    sudo nano /etc/systemd/system/tomcat.service

    Add the following content:

    Copy<br /> Code 

    
[Unit]
    
Description=Apache Tomcat Web Application Container
    
After=network.target
    

    [Service]
    
Type=forking
    

    Environment=”JAVA_HOME=/usr/lib/jvm/java-1.21.0-openjdk-amd64″
    
Environment=”CATALINA_PID=/opt/tomcat/temp/tomcat.pid”
    
Environment=”CATALINA_HOME=/opt/tomcat”
    
Environment=”CATALINA_BASE=/opt/tomcat”
    
Environment=”CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC”
    
Environment=”JAVA_OPTS=-Djava.awt.headless=true -Djava.security.egd=file:/dev/./urandom”
    

    ExecStart=/opt/tomcat/bin/startup.sh
    
ExecStop=/opt/tomcat/bin/shutdown.sh
    

    User=tomcat
    
Group=tomcat
    
UMask=0007
    
RestartSec=10
    
Restart=always
    

    [Install]
    
WantedBy=multi-user.target
    

    

    
			
    
        
    

    Reload the systemd daemon:
    

    
			
    
                
    
                    
    
                        
    
                        
    
                        
    
                    
    
                    
    
                        
                        Copy<br />
Code
                        
                        
                    
    
                
    
                
    

    sudo systemctl daemon-reload

    

    
			
    
        
    

    Start and enable the Tomcat service:
    

    
			
    
                
    
                    
    
                        
    
                        
    
                        
    
                    
    
                    
    
                        
                        Copy<br />
Code
                        
                        
                    
    
                
    
                
    

    sudo systemctl start tomcat
sudo systemctl enable tomcat

    

    
			
    
        
    

    Step 6: Allow Port 8080
    

    If you have a firewall enabled, allow traffic on port 8080:
    

    
			
    
                
    
                    
    
                        
    
                        
    
                        
    
                    
    
                    
    
                        
                        Copy<br />
Code
                        
                        
                    
    
                
    
                
    

    sudo ufw allow 8080/tcp

    

    
			
    
        
    

    Step 7: Verify Installation
    

    Open your web browser and navigate to http://<your_server_ip>:8080. You should see the Apache Tomcat homepage.
