The older version of Tomcat is widely used by Java servers due to its robustness, extensibility, dependable core engine, and extensive testing by skilled developers.

Shall we start with article How to Install Apache Tomcat Server on Ubuntu 22.04.

What is Apache Tomcat?

The Apache Software Foundation developed and maintains the open source web server for Java programs known as Apache Tomcat. Its purpose is to host and distribute Java servlets, which are server side Java code snippets responsible for managing HTTP responses from client Java applications. 

Further, Apache Tomcat functions as a web server, providing critical web server processing capabilities for the relevant servlets, rather than an entire application server with features such as load balancing and data persistence. Additionally, it supports the init(), service(), and destroy() methods as part of the Java servlet lifecycle.

Besides, Tomcat offers a web based administration panel that enables administrators to keep an eye on and control the server and its applications. Due to this managing and configuring Tomcat deployments is simple.

Servlet and JSP Support

Apache Tomcat provides full support for Java Servlet API and JavaServer Pages(JSP). Java is consequently a tool that programmers may use to build dynamic, data driven web applications.

Cross Platform

Tomcat is compatible with Windows, Linux, and macOS. Developers that operate across several platforms are drawn to it by its flexibility.

Resource pooling

The connection pooling functionality of Tomcat permits the sharing of many database connections among separate requests. As a result, database-dependent applications might operate more efficiently.

Sessional management

The connection pooling function of Tomcat permits the sharing of many database connections among separate requests. As a result, applications that rely on databases might work more efficiently.

Monitoring and logging

Developers follow the performance of their applications and identify problems as they occur due to Tomcat’s robust monitoring and logging capabilities.

How to Install Apache Tomcat Server on Ubuntu 22.04

In this section, we explain how to install the Apache Tomcat server on Ubuntu.


  • An Ubuntu 22.04 server is installed on your system.
  • A root user or a user with sudo privileges.

Install Java JDK

Apache Tomcat is based on Java. So the Java JDK must be installed on your server. Install it using the following command.

					apt install openjdk-11-jdk

After installing Java JDK, please verify the Java installation using the following command.

					java --version

You should see the Java version in the following output.

					openjdk 11.0.18 2023-01-17
OpenJDK Runtime Environment (build 11.0.18+10-post-Ubuntu-0ubuntu122.04)
OpenJDK 64-Bit Server VM (build 11.0.18+10-post-Ubuntu-0ubuntu122.04, mixed mode, sharing)

Install Apache Tomcat

It is a good idea to create a dedicated user to run the Apache Tomcat server. Create a new user called tomcat using the following command.

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

Next, download the latest version of Apache Tomcat from its official website using the following command.


Once the Apache Tomcat is downloaded, extract the downloaded file with the following command.

					tar -xvf apache-tomcat-10.0.20.tar.gz

Next, move the content of the extracted directory to the Apache Tomcat home directory.

					mv apache-tomcat-10.0.20/* /opt/tomcat

Then, change ownership of the Tomcat directory to tomcat.

					chown -R tomcat: /opt/tomcat

Next, set the execution permission on Tomcat binary file.

					sh -c 'chmod +x /opt/tomcat/bin/*.sh'

Once you are done, please proceed to the next step.

Create a Systemd Service File for Apache Tomcat

It is also recommended to create a systemd service file to manage the Apache Tomcat service. Create it with the following command.

					nano /etc/systemd/system/tomcat.service

Add the following configurations.

Description=Apache Tomcat



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


ExecReload=/bin/kill $MAINPID



Save and close the file then reload the systemd daemon to apply the changes.

					systemctl daemon-reload

Next, start the Apache Tomcat service and enable it to start at system reboot with the following command.

					systemctl enable --now tomcat

Also check the status of the Apache Tomcat service with the following command.

					systemctl status tomcat

This shows you the active status of Apache Tomcat.

To check the Apache Tomcat listening ports, run the following command.

					ss -antpl | grep -i java

You should see Tomcat ports on the following screen.

Configure Apache Tomcat

At this point, the Apache Tomcat is installed and running on your server. Now, you need to add an admin user and password to secure the Apache Tomcat. You can do it by editing tomcat-users.xml file.

					nano /opt/tomcat/conf/tomcat-users.xml

Add the following lines above the line </tomcat-users>:

   <role rolename="admin-gui"/>
   <role rolename="manager-gui"/>
   <user username="admin" password="securepassword" roles="admin-gui,manager-gui"/>


Save and close the file when you are finished.

Enable Apache Tomcat Remote Access

By default, Apache Tomcat is accessed only from the localhost. To access the Apache Tomcat from the remote machine, you need to edit the context.xml file and remove the access restriction.

To enable remote access for Tomcat Manager, edit the context.xml file.

					nano /opt/tomcat/webapps/manager/META-INF/context.xml

Remove the following lines:

					  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />


To enable remote access for Tomcat Host Manager, edit the context.xml file.

					nano /opt/tomcat/webapps/host-manager/META-INF/context.xml

Remove the following lines.

					  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />


Save and close the file when you are done. Then, restart the Tomcat service to implement the changes.

					systemctl restart tomcat

Access Apache Tomcat

Now, Apache Tomcat is installed on your server. Access it using the URL http://your-server-ip:8080 on your web browser.  You should see the Tomcat dashboard on the following screen.

Click on the Manager App. You will be asked to provide Tomcat admin username and password as shown below.
