Today we're going to install and config tomcat.
#!/bin/bash
# Step 1: Install Java
sudo apt-get update
sudo apt-get install -y default-jdk
# Step 2: Create Tomcat User and Group
sudo groupadd tomcat
sudo useradd -s /bin/false -g tomcat -d /opt/tomcat tomcat
# Step 3: Download Tomcat 10
cd /opt
sudo wget https://dlcdn.apache.org/tomcat/tomcat-10/v10.1.19/bin/apache-tomcat-10.1.19.tar.gz
sudo tar xzvf apache-tomcat-10*tar.gz
sudo mv apache-tomcat-10.1.19 tomcat
# Step 4: Update Permissions
sudo chgrp -R tomcat /opt/tomcat
sudo chmod -R g+rwx /opt/tomcat/conf
sudo chmod g+x /opt/tomcat/conf
sudo chown -R tomcat /opt/tomcat/webapps/ /opt/tomcat/work/ /opt/tomcat/temp/ /opt/tomcat/logs/
# Step 5: Create a systemd Service File
sudo tee /etc/systemd/system/tomcat.service <<EOF

# Step 6: Reload systemd
sudo systemctl daemon-reload
# Step 7: Start and enable Tomcat service
sudo systemctl start tomcat
sudo systemctl enable tomcat
# Step 8: Allow port 8080 in firewall
sudo ufw allow 8080
# Step 9: Deploy WAR file
sudo cp ~/Documents/war/sample.war /opt/tomcat/webapps/
# Step 10: Restart Tomcat
sudo systemctl restart tomcat
# Step 11: Verify Tomcat status
sudo systemctl status tomcat
sample.war makes sample folder ultimately when we move the .war file.
