Step 1 – Prerequisites

Tomcat 9 is designed to run on Java SE 8 and later. So make sure you have installed the correct version on your system.

java -version

openjdk version "11.0.7" 2020-04-14 LTS
OpenJDK Runtime Environment 18.9 (build 11.0.7+10-LTS)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.7+10-LTS, mixed mode, sharing)

Step 2 – Download Tomcat Archive

Download Apache Tomcat 9 archive file using following commands or you can visit Tomcat 9 official download page for download most recent available version. After downloading extract archive file in /usr/local directory. You may change this location as per your setup.

wget wget http://www-us.apache.org/dist/tomcat/tomcat-9/v9.0.50/bin/apache-tomcat-9.0.50.tar.gz
tar xzf apache-tomcat-9.0.50.tar.gz
sudo mv apache-tomcat-9.0.50 /usr/local/tomcat9 

Step 3 – Set Environment Variables

Let’s configure the CATALINA_HOME environment variable in your system using the following commands. It is required to run the Tomcat server.

echo "export CATALINA_HOME="/usr/local/tomcat9"" >> ~/.bashrc
source ~/.bashrc

Step 4 – Setup User Accounts

Finally we need to create user accounts to secure and access admin/manager pages. Edit conf/tomcat-users.xml file in your editor and paste inside <tomcat-users> </tomcat-users> tags.

vim /usr/local/tomcat9/conf/tomcat-users.xml

<!-- 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 – Start Tomcat Service

Tomcat is very easy to use, There is no need to compile its source. You simply extract the archive and start the tomcat server. Tomcat by default start on port 8080, So make sure no other application using the same port.

cd /usr/local/tomcat9
./bin/startup.sh

[Sample Output]

Using CATALINA_BASE:   /usr/local/tomcat9
Using CATALINA_HOME:   /usr/local/tomcat9
Using CATALINA_TMPDIR: /usr/local/tomcat9/temp
Using CLASSPATH:       /usr/local/tomcat9/bin/bootstrap.jar:/usr/local/tomcat9/bin/tomcat-juli.jar
Tomcat started.
