Installing Apache Tomcat on Ubuntu Server
Step 1: Update Your Ubuntu Server
Before we begin installing Apache Tomcat, we need to ensure that our Ubuntu server is up-to-date. This can be done with the following command:
Command |
Description |
|---|---|
sudo apt-get update |
Updates the package lists for upgrades and new packages. |
sudo apt-get upgrade |
Upgrades the currently installed packages. |
These commands will download and install any updates for your Ubuntu server.
Step 2: Install Java Development Kit (JDK)
Apache Tomcat is a Java-based application server, so we need to install the Java Development Kit (JDK) before we can install Tomcat. To do this, we will use the following command:
Command |
Description |
|---|---|
sudo apt-get install default-jdk |
Installs the default JDK for Ubuntu. |
After the installation is complete, you can verify that Java is installed by running the following command:
Command |

|---|---|
java -version |
Displays the version of Java installed. |
Step 3: Download and Install Apache Tomcat
Now that we have installed the JDK, we can download and install Apache Tomcat. Here are the steps to download and install Tomcat:
- Visit the Apache Tomcat download page at https://tomcat.apache.org/download-90.cgi.
- Click the link for the latest version of Tomcat (at the time of writing, it is “9.0.52”).
- Scroll down to the “Core” section and click the link for the “tar.gz” file.
- Once the download is complete, extract the contents of the file to a directory of your choice. We will use
/opt/tomcat/for this example.
After extracting the files, you can start Tomcat by running the following command:
Command |
Description |
|---|---|
/opt/tomcat/apache-tomcat-9.0.52/bin/startup.sh |
Starts the Tomcat server. |
Step 4: Verify Tomcat is Running
