cd /usr/local
wget wget http://www-us.apache.org/dist/tomcat/tomcat-9/v9.0.10/bin/apache-tomcat-9.0.10.tar.gz
tar xzf apache-tomcat-9.0.10.tar.gz
mv apache-tomcat-9.0.10 tomcat9

Step 3 – Configure Environment Variables

Let’s configure CATALINA_HOME environment variable in your system using the following commands. Its 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_HOME:   /usr/local/tomcat9
Using CATALINA_TMPDIR: /usr/local/tomcat9/temp
