The Java-based web application is hosted by Tomcat, a web server. The Apache Tomcat team has released Tomcat 9. This guide will show you how to install Tomcat 9 on Ubuntu 19.10, 18.04 LTS, and 16.04 LTS.

Step 1: Verify/Install Java

Before you can install Apache Tomcat on a Linux VPS, you must first install Java. To run Tomcat 9, you will need Java 8 or later. You should double-check that the correct version of Java is installed.

					java -version

java version "11.0.2" 2019-01-15 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.2+9-LTS)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.2+9-LTS, mixed mode)

Run the commands below to fulfill requirements if you do not have Java installed or have an older version.

					sudo apt-get update
sudo apt-get install default-jdk

Step 2: Download and Install Apache Tomcat 9

To get the Tomcat archive, go to the official download page or one of its mirrors. Using the commands below, download and install the Apache Tomcat 9 archive file. You should also go to the official download page to get the latest version.

tar xzf apache-tomcat-9.0.35.tar.gz
sudo mv apache-tomcat-9.0.35 /usr/local/tomcat9

Step 3: Configure the Required Environment Variables

Configure the Tomcat’s required environment variables now. Set CATALINA HOME to the tomcat directory that was extracted. Set Java environment variables according to the Java version installed on your system.

					echo "export CATALINA_HOME="/usr/local/tomcat9"" >> ~/.bashrc
echo "export JAVA_HOME="/usr/lib/jvm/java-11-oracle"" >> ~/.bashrc
echo "export JRE_HOME="/usr/lib/jvm/java-11-oracle"" >> ~/.bashrc
source ~/.bashrc

Step 4: Create User Accounts for Tomcat

Finally, in order to secure and access admin/manager pages, we must create user accounts. Copy the contents of the conf/tomcat-users.xml file into the and /tomcat-users> tags.

					<!-- user manager can access only manager section -->
<role rolename="manager-gui" />
<user username="manager" password="_SECRET_PASSWORD_" roles="manager-gui" />

<!-- user admin can access manager and admin section both -->
<role rolename="admin-gui" />
<user username="admin" password="_SECRET_PASSWORD_" roles="manager-gui,admin-gui" />

Step 5: Enable Remote IP Host/Manager

Only localhost is allowed to access the default manager and host-manager web pages. You must enable the IP or IP range in the application-specific context.xml file to access these pages from a remote system.

					Manager File: ./webapps/manager/META-INF/context.xml
Host Manager File: ./webapps/host-manager/META-INF/context.xml


Edit the above files and replace your IP address like the one seen in the screenshot. Restart Tomcat after you have made the changes.

Step 6: Start Tomcat 9 Service

Tomcat is very simple to use; there is no need to compile its source. Simply unpack the archive and launch the Tomcat server. Tomcat starts on port 8080 by chance, so make sure no other applications are using the same port.

					cd /usr/local/apache-tomcat9
chmod +x ./bin/


					Using CATALINA_BASE:   /usr/local/tomcat9
Using CATALINA_HOME:   /usr/local/tomcat9
Using CATALINA_TMPDIR: /usr/local/tomcat9/temp
Using JRE_HOME:        /usr/lib/jvm/java-11-oracle
Using CLASSPATH:       /usr/local/tomcat9/bin/bootstrap.jar:/usr/local/tomcat9/bin/tomcat-juli.jar
Tomcat started.

Step 7: Access Tomcat 9 in Browser

The default port for the Tomcat server is 8080. Connect your server to port 8080 in your web browser to use Tomcat.

Tomcat Home– This is Tomcat 9’s default home page. This page does not need authentication to access.
