How To Install Apache Tomcat on Linux Mint 21

Install Apache Tomcat on Linux Mint 21

In this tutorial, we will show you how to install Apache Tomcat on Linux Mint 21. For those of you who didn’t know, Apache Tomcat is an open-source Java servlet container. Tomcat is developed and maintained by a free group of developers under the Apache Software Foundation’s auspices and is licensed under the Apache License 2.0.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of an Apache Tomcat on Linux Mint 21 (Vanessa).

Prerequisites

  • A server running one of the following operating systems: Linux Mint 21 (Vanessa).
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo useror access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Apache Tomcat on Linux Mint 21 Vanessa

Step 1. Before running the tutorial below, it’s important to make sure your system is up to date by running the following apt commands in the terminal:

sudo apt update
sudo apt install software-properties-common apt-transport-https wget ca-certificates gnupg2

Step 2. Installing Java.

Apache Tomcat required Java installation. Now run the following command to install Java to your system using the following command:

sudo apt install default-jdk

Check the currently installed version by simply running the command below:

java --version

Step 3. Installing Apache Tomcat on Linux Mint 21.

By default, Apache Tomcat is not available on the Linux Mint 21 base repository. Now we download the Apache Tomcat package from the official page using the wget command below:

wget https://dlcdn.apache.org/tomcat/tomcat-10/v10.0.23/bin/apache-tomcat-10.0.23.tar.gz

Next, extract the downloaded archive:

tar xvf apache-tomcat-10.0.23.tar.gz

Then, move it to the /usr directory using the following command:

sudo mv apache-tomcat-10.0.23 /usr/share/apache-tomcat

Next, create a user for Apache Tomcat and give ownership:

sudo useradd -M -d /usr/share/apache-tomcat tomcat
sudo chown -R tomcat /usr/share/apache-tomcat

Step 4. Configure Apache Tomcat

Now allow access to Apache Tomcat UI from your IP address:

sudo nano /usr/share/apache-tomcat/webapps/manager/META-INF/context.xml

Allow specific IP address by adding it to the line:

<Valve className="org.apache.catalina.valves.RemoteAddrValve"
allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1|192.168.0.1" />

Do the same with the following file:

sudo nano /usr/share/apache-tomcat/webapps/host-manager/META-INF/context.xml

To allow any IP address to access remove the added IP above:

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

Next, we set up a secure Apache Tomcat dashboard:

sudo nano /usr/share/apache-tomcat/conf/tomcat-users.xml

Add the following file above <tomcat-users xm..:

<!-- manager section user role -->
<role rolename="manager-gui" />
<user username="manager" password="Your-Strong-Passwd" roles="manager-gui" />

<!-- admin section user role -->
<role rolename="admin-gui" />
<user username="admin" password="Your-Strong-Passwd" roles="manager-gui,admin-gui" />

Step 5. Create Systemd for Apache Tomcat

Now we create systemd unit for tomcat to start/stop and restart service:

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

Add the following file:

[Unit]
Description=Tomcat
After=syslog.target network.target

[Service]
Type=forking

User=tomcat
Group=tomcat

Environment=JAVA_HOME=/usr/lib/jvm/default-java
Environment='JAVA_OPTS=-Djava.awt.headless=true'

Environment=CATALINA_HOME=/usr/share/apache-tomcat
Environment=CATALINA_BASE=/usr/share/apache-tomcat
Environment=CATALINA_PID=/usr/share/apache-tomcat/temp/tomcat.pid

ExecStart=/usr/share/apache-tomcat/bin/catalina.sh start
ExecStop=/usr/share/apache-tomcat/bin/catalina.sh stop

[Install]
WantedBy=multi-user.target

Save and close the file, then reload systemd daemon:

sudo systemctl daemon-reload
sudo systemctl enable tomcat
sudo systemctl status tomcat

Step 6. Configure Firewall.

Now we set up an Uncomplicated Firewall (UFW) with Tomcat to allow public access on default web port 8080:

sudo ufw allow OpenSSH
sudo ufw allow 8080
sudo ufw enable

Step 7. Accessing Apache Tomcat Web Interface.

Once successfully installed, open your web browser and access the OwnCloud installation wizard using the URL http://your-IP-address:8080. You will be redirected to the following page:
