How to Install Tomcat on an Ubuntu 20.04 Server

Tomcat is a popular web container that allows you to run Java applications on a server. This article will guide you through installing Tomcat on an Ubuntu 20.04 server.

1. Installing Java

Before installing Tomcat, ensure Java is installed on your server. Execute the following commands:

sudo apt update
sudo apt install default-jdk

2. Downloading and Installing Tomcat

Now, let’s download and install Tomcat using these commands:

cd /tmp
wget https://downloads.apache.org/tomcat/tomcat-9/v9.0.37/bin/apache-tomcat-9.0.37.tar.gz
sudo tar xzvf apache-tomcat-9.0.37.tar.gz -C /opt
sudo mv /opt/apache-tomcat-9.0.37 /opt/tomcat
sudo useradd -r -m -U -d /opt/tomcat -s /bin/false tomcat
sudo chown -R tomcat: /opt/tomcat
sudo sh -c 'chmod +x /opt/tomcat/bin/*.sh'

3. Configuring Tomcat

Now, configure Tomcat by opening the /opt/tomcat/conf/server.xml file and editing the port Tomcat will use. This is typically port 8080. Locate the line <Connector port="8080" and change the port if necessary.

4. Starting Tomcat

Start Tomcat using this command:

sudo /opt/tomcat/bin/startup.sh

Tomcat is now running. You can verify this by accessing http://your_server_ip:8080 in your web browser, replacing your_server_ip with your server’s IP address.
