AWS Tutorial: How to install Tomcat 9 in AWS EC2 Instance

In this tutorial I will show you how you install Tomcat Server in your AWS Linux.

Prerequisite:

AWS Account and login to AWS Console, here.
Create an AWS EC2 with Amazon Linux 2 AMI instance and Instance type between *micro-*small.
Install Java JDK on Amazon Linux, here.

1) Install Tomcat:

Go to tomcat.apache.org/download and find the latest stable version of tomcat, as this tutorial wrote, tomcat 9.0.41 is the latest stable we can use. Get the URL address of "tar.gz" file below;

tomcat9-download

Go in your in your EC2 instance and remember log as "sudo" 1st before you execute below command:

wget https://downloads.apache.org/tomcat/tomcat-9/v9.0.41/bin/apache-tomcat-9.0.41.tar.gz

2) Extract TAR file
Go /usr/local or /usr/shared and then extract the TAR file you downloaded in previous step.

tar -xvf /root/apache-tomcat-9.0.41.tar.gz

3) Rename the Tomcat

Rename tomcat to simplest name so easy for us to maintain in later stage.

mv apache-tomcat-9.0.41 tomcat9

After that your "tomcat9" will look like below;

Tomcat-Folder-Structure

4) Add User for Tomcat

useradd -r tomcat

5) Give User Permission
Give permission user to tomcat9 folder:

chown -R tomcat:tomcat /usr/local/tomcat9

6) Create Tomcat Service

Copy below script for your Tomcat Service file

sudo tee /etc/systemd/system/tomcat.service<<EOF
[Unit]
Description=Tomcat Server
After=syslog.target network.target

[Service]
Type=forking
User=tomcat
Group=tomcat

Environment=CATALINA_HOME=/usr/local/tomcat9
Environment=CATALINA_BASE=/usr/local/tomcat9
Environment=CATALINA_PID=/usr/local/tomcat9/temp/tomcat.pid

ExecStart=/usr/local/tomcat9/bin/catalina.sh start
ExecStop=/usr/local/tomcat9/bin/catalina.sh stop

RestartSec=12
Restart=always

[Install]
WantedBy=multi-user.target
EOF

7) Enable and start tomcat service:

#Reload tomcat service
sudo systemctl daemon-reload

#Restart/Start tomcat service
sudo systemctl start tomcat

#Check tomcat service status
systemctl status tomcat.service

8) Check Tomcat Service and Host-Manager(GUI)
