How to Install Apache Tomcat 10 on Ubuntu 22.04 with Nginx

Install Apache Tomcat 10 on Ubuntu 22.04 with Nginx. Apache Tomcat is an open source web server and a servlet container which is mainly used to server Java based applications.

In this guide, you are going to learn how to install Apache Tomcat 10 on Ubuntu 22.04 and secure the setup with Nginx and Let’s Encrypt SSL.


  • A server with Ubuntu 22.04 OS
  • A user with sudo privileges.

Initial Setup

Start by updating the server packages to the latest version available.

sudo apt update
sudo apt dist-upgrade -y

Create New User for Tomcat

It would be better if Tomcat runs as it’s own unprivileged user. Execute the following command to create a new user with required privileges for Tomcat. This user wont be allowed to be logged in to SSH.

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

Install Java

Install default JDK using the below command. Check here for more detailed guide to install Java.

sudo apt install default-jdk

Once the installation is completed, check the version using the following command.

java -version

Your output should be similar to the one below.

openjdk version "11.0.15" 2022-04-19
OpenJDK Runtime Environment (build 11.0.15+10-Ubuntu-0ubuntu0.22.04.1)
OpenJDK 64-Bit Server VM (build 11.0.15+10-Ubuntu-0ubuntu0.22.04.1, mixed mode, sharing)

Install Apache Tomcat

Download the latest version of Tomcat from their official downloads page. Choose the tar.gz under the core section.

Download the archive using wget.

cd ~/

Extract the contents to /opt/tomcat directory.

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

Configure correct permissions for Tomcat files.

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

Configure Admin Users

Now we need to setup users who can access the Host manager and the Manager pages in Tomcat.

Add the users with passwords in /opt/tomcat/conf/tomcat-users.xml

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

Add the following lines before the end tag.

<role rolename="manager-gui" />
<user username="manager" password="secure_password" roles="manager-gui" />

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

Now we have 2 users who can access the Manager and the Host manager pages.

Configure Tomcat as a Service

Here we will configure a systemd service to manage Tomcat to start, stop and restart automatically.

Note the Java location.

sudo update-java-alternatives -l
java-1.11.0-openjdk-amd64      1111       /usr/lib/jvm/java-1.11.0-openjdk-amd64

Create a systemd file.

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

Add the following contents to the file.




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




Replace JAVA_HOME variable with the one you noted before.

Reload systemd daemon for the changes to take effect.

sudo systemctl daemon-reload

Start Tomcat.

sudo systemctl start tomcat

Enable Tomcat to start at system boot.

sudo systemctl enable tomcat

Check Tomcat status.

sudo systemctl status tomcat
● tomcat.service - Tomcat
     Loaded: loaded (/etc/systemd/system/tomcat.service; disabled; vendor preset: enabled)
     Active: active (running) since Wed 2022-05-25 06:41:36 UTC; 6s ago
    Process: 5155 ExecStart=/opt/tomcat/bin/ (code=exited, status=0/SUCCESS)
   Main PID: 5302 (java)
      Tasks: 29 (limit: 1151)
     Memory: 132.7M
     CGroup: /system.slice/tomcat.service

Install Nginx

Install Nginx using the following command.

sudo apt install nginx

Remove default configurations

sudo rm /etc/nginx/sites-available/default
sudo rm /etc/nginx/sites-enabled/default

Configure Nginx Proxy for Tomcat

Create new Nginx configuration

sudo nano /etc/nginx/sites-available/yourdomainname.conf

Paste the following

server {
     listen [::]:80;
     listen 80;


     location / {
         proxy_pass http://localhost:8080;
         proxy_http_version 1.1;
         proxy_set_header Upgrade $http_upgrade;
         proxy_set_header Connection 'upgrade';
         proxy_set_header Host $host;
         proxy_cache_bypass $http_upgrade;

Save and exit the file.

Enable your configuration by creating a symbolic link.

sudo ln -s /etc/nginx/sites-available/yourdomainname.conf /etc/nginx/sites-enabled/yourdomainname.conf

Install Let’s Encrypt SSL with Certbot

Install Certbot package.

sudo apt install python3-certbot-nginx

Install SSL certificate using the below command.

sudo certbot --nginx --redirect --no-eff-email --agree-tos -m [email protected] -d -d

If your domain is pointed to the server the free SSL certificate will get installed and HTTP to HTTPS redirection will get configured automatically and Nginx will get restarted by itself for the changes to take effect.

If you want to restart you can check your Nginx configuration and restart it.

sudo nginx -t
sudo service nginx restart

Verify Tomcat Installation

Now check your domain in your browser.
