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

Step 1: Preparations

Before installing Tomcat on Linux, ensure that Java is installed on your system. If not, we will use the OpenJDK package, which is the default Java Development Kit. Open the terminal on your Ubuntu system and first update the package sources with the following command:

This ensures that you get the latest version of the OpenJDK package when installing Java on your system. Then, install Java with this command:

Check the Java installation to ensure it was successful:

Step 2: Set Up Tomcat User

It is not recommended to run Tomcat under a root account. Therefore, we need to create a new user under which the Tomcat server will run on our system. Use the following command to create the user:

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

Here, the user “tomcat” is associated with the directory “/opt/tomcat” where the Tomcat service will run.

Step 3: Download Tomcat Package

After creating the user, we need to download the Tomcat package to install Tomcat on Linux. Use the “wget” command to download the Tomcat package from the official website:

wget -c

Step 4: Install Tomcat on Linux

Once the tar archive is downloaded on your system, extract it to the directory “/opt/tomcat” with the following command:

sudo tar xf apache-tomcat-9.0.34.tar.gz -C /opt/tomcat

Create a symbolic link pointing to the Tomcat installation directory to facilitate future updates:

sudo ln -s /opt/tomcat/apache-tomcat-9.0.34 /opt/tomcat/updated

Change permissions in the Tomcat directory with the following commands:

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

Step 5: Configure Tomcat Service

After installation, you need to configure Tomcat to run it as a service. Create a systemd unit file under “/etc/systemd/system” with a text editor of your choice:

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

Insert the following content into the file and save it:

Description=Apache Tomcat Web Application Container


Environment="CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC"



Update the system daemon to apply the changes:

Start the Tomcat service with the following command:

Check the status of the Tomcat service:

Step 6: Allow Port 8080

To allow Tomcat to communicate on port 8080, adjust the firewall configuration:

Step 7: Verify Installation

To verify the successful installation of Tomcat, open your web browser and enter your server’s IP address followed by “:8080”, e.g., “http://:8080”. You should see the Tomcat homepage.
