In this tutorial, we will show you how to install and configure Apache Tomcat nine.0.34 with the Java OpenJDK 11 on the latest version of ubuntu twenty.04 Server.

Prerequisites

For this tutorial, we will install the Apache Tomcat on the Ubuntu 20.04 Server with 1 GB of RAM, 25 GB costless disk space, and 2 CPUs.

What we will do?

• Install Java OpenJDK
• Setup JAVA_HOME Environment variable
• Download and Install Apache Tomcat nine.0.34
• Setup Apache Tomcat equally a Systemd Service
• Setup Apache Tomcat Hallmark
• Testing

Step 1 - Install Coffee OpenJDK

First, we will install the Java OpenJDK packages to our Ubuntu xx.04 Server.

By default, the latest Ubuntu xx.04 repository provides multiple Coffee versions, including the OpenJDK 11.

Update all repository on your organisation and install Java OpenJDK 11 using the apt command equally below.

cd /opt/
wget -q https://downloads.apache.org/tomcat/tomcat-nine/v9.0.34/bin/apache-tomcat-9.0.34.tar.gz

Once it'south downloaded, extract the Apache Tomcat binary file and rename the directory to 'tomcat'.

tar -xf apache-tomcat-9.0.34.tar.gz
mv apache-tomcat-9.*/ tomcat/

Next, alter the ownership of the '/opt/tomcat' directory to the user 'tomcat'.

chown -R tomcat:tomcat /opt/tomcat
chmod +ten /opt/tomcat/bin/*

The Apache Tomcat is downloaded at the '/opt/tomcat' directory.

Adjacent, nosotros will configure the Apache Tomcat 'CATALINA_HOME' surround variable, which is located at the '/opt/tomcat' directory. Advertisement

Edit the '~/.bashrc' configuration using vim editor.

vim ~/.bashrc

Paste the following configuration into information technology.

export CATALINA_HOME=/opt/tomcat

Relieve and close.

Now reload the '~/.bashrc' config file and check the 'CATALINA_HOME' environs variable.

source ~/.bashrc
repeat $CATALINA_HOME

You will get the '/opt/tomcat' equally a value of the environment variable 'CATALINA_HOME'.

Now y'all can start the Apache Tomcat manually using the following control.

$CATALINA_HOME/bin/startup.sh

Yous will get the Apache Tomcat is started.

The Apache Tomcat is upwardly and running on the Ubuntu system, and it's running on default port '8080'. Cheque it using the following command.

ss -plnt

And you will become the port '8080' that is used by the Java awarding.

Now stop the Apache Tomcat and alter the buying of the '/opt/tomcat' directory to the 'tomcat' user as beneath.

$CATALINA_HOME/bin/shutdown.sh
chown -hR tomcat:tomcat /opt/tomcat/

As a result, the installation and configuration of Apache Tomcat have been completed.

Pace iv - Setup Apache Tomcat every bit a Systemd Service

For this tutorial, we will run the Apache Tomcat as a systemd service. And for this footstep, nosotros will create a new systemd service file named 'tomcat.service' for our Apache Tomcat installation.

Go to the '/etc/systemd/system' directory and create a new service file 'tomcat.service'.

cd /etc/systemd/system/
vim tomcat.service

At present paste the following configuration into it.

[Unit]
Clarification=Apache Tomcat 9 Servlet Container
After=syslog.target network.target
[Service]
User=tomcat
Group=tomcat
Type=forking
Environment=CATALINA_PID=/opt/tomcat/tomcat.pid
Environment=CATALINA_HOME=/opt/tomcat
Environment=CATALINA_BASE=/opt/tomcat
ExecStart=/opt/tomcat/bin/startup.sh
ExecStop=/opt/tomcat/bin/shutdown.sh
Restart=on-failure
                
[Install]
WantedBy=multi-user.target

cd /opt/tomcat/conf
vim tomcat-users.xml

Alter the username and password with your own and paste the following configuration into it.

<role rolename="manager-gui"/>
<user username="hakase" countersign="hakasepassword01" roles="manager-gui,admin-gui"/>

Save and shut.

Next, get to the '/opt/tomcat/webapps/manager/META-INF/' directory and edit the Apche Tomcat mnager configuration 'context.xml'.

cd /opt/tomcat/webapps/manager/META-INF/
vim context.xml

Comment the following line below.

<!--  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::ane|0:0:0:0:0:0:0:ane" /> -->

Save and close.

Next, go to the '/opt/tomcat/webapps/host-manager/META-INF/' directory nd edit the Apache Tomcat hos- managing director configuration 'context.xml'.

cd /opt/tomcat/webapps/host-director/META-INF/
vim context.xml

Comment the following line below.

<!--  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:ane" /> -->

Salve and close.

Now restart the Apache Tomcat service using the control below.

systemctl restart tomcat

Equally a result, the Apache Tomcat authentication for manager and host-manager has been enabled.

Stride half-dozen - Testing

Open your spider web browser and type the server IP address with port 8080. ANd yous will come across the Apache Tomcat default index page that informs that the installation is successful.

http://x.5.v.34:8080/

Next, add the '/manager/html' path on the  URL and you volition be prompted for the Tomcat managing director authentication.

http://ten.5.5.34:8080/manager/html

Type your username and countersign, and you will go the Apache Tomcat Manager Dashboard.

Next, become to the Apache Tomcat virtualhost director '/host-manager/html'.
