How to Install Tomcat 10 on Debian 10

Apache Tomcat is an open source web server with servlet container for publishing Java based web applications. Tomcat is developed and maintained by an open community of developers under the auspices of the Apache Software Foundation. As of today, Tomcat 10 is the latest stable version available for the installation on development and production environments. To know more about the Apache Tomcat visit apache official site

This tutorial will help you to how to install Apache Tomcat 10 on Debian 10 Buster Linux system.


A running Debian 10 system with sudo privileged account shell access.

You can get cheaper instances from DigitalOcean hosting.

Step 1 – Install Java

Tomcat 10 required JRE 8 or higher version installed on your system. If your system don’t have JRE installed, Use the following commands to install OpenJDK to fulfill the requirements.

sudo apt update 
sudo apt install default-jdk -y 

Check the current active Java version:

java -version 

openjdk 2020-11-04
OpenJDK Runtime Environment (build
OpenJDK 64-Bit Server VM (build, mixed mode, sharing)

Step 2 – Create Tomcat User

Its good to have a dedicated user account for running a Tomcat server. So create a new user with name “tomcat”, which is recommended for the security purposes mainly for production deployments.

To create a new account, type:

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

The above command will create a user and group with name “tomcat” in your system.

Step 3 – Install Tomcat on Debian 10

The Apache Tomcat development team releases latest version of Tomcat time to time. So it will be good check download latest Tomcat version from the official download server. Use below command to download Tomcat 10.


After downloading the archive file, extract file under the tomcat home directory /opt/tomcat with skipping parent folder.

sudo tar xzvf apache-tomcat-10*tar.gz -C /opt/tomcat --strip-components=1 

Next, set the proper file permissions.

sudo chown -R tomcat:tomcat /opt/tomcat/ 
sudo chmod -R u+x /opt/tomcat/bin 

You have now the latest Tomcat application on your system.

Step 4 – Create Tomcat User

Now, configure your tomcat with user accounts to secure access of admin/manager pages. To do this, edit conf/tomcat-users.xml file in your editor and paste the following code inside tags. We recommend changing the password in the below configuration with high secured password.

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

Add the following values. Make sure to change password for admin and manager access.

Save file and close.

Step 5 – Enable Remote Tomcat Access

The default Tomcat manager and host-manager applications are accessible for localhost only. To allow access these pages from the remote system, you need modify following configuration files.

You can either allow specific remote system or allow all. Edit the context.xml file for manager and host manager application:

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

Comment out the section added for IP address restriction to allow connections from anywhere.


Also edit the context.xml for host-manager interface and comment the similar section as above.

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

Tomcat allow remote access

Save all files and close it.

Step 6 – Create a Tomcat Systemd Unit File

Tomcat provides bash scripts to start, stop service. But, to make it simpl, create a startup script to manage Tomcat as systemd service. Let’s create a tomcat.service file with the following content:

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



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



Reload the systemd daemon service to load newly create files.

sudo systemctl daemon-reload 

Now, start the Tomcat application for the first time.

sudo systemctl start tomcat.service 

Next, enable the tomcat service to auto start for subsequent system boots. This is more important for the production deployments.

sudo systemctl enable tomcat.service 

As of now, the tomcat application is running on your system. You can verify the service status by executing the command as below. Make sure the status is showing “active (running)“.

sudo systemctl status tomcat.service 

Manage Tomcat with systemd

That’s it. You have successfully configured Tomcat 10 on your Debian system.

Step 7 – Access the Tomcat Web Interface

The default Tomcat server runs on port 8080. As you have configured Tomcat on your system, you can access web interface from your system. You can access tomcat interfaces by entering your server’s IP address or a domain name pointed to that server, followed by port 8080 in your browser:

Change tecadmin.local with your server ip or domain or localhost.

Click Host Manager button home page or directly type /host-manager url in main Tomcat server to access it.
