What is Apache Tomcat? A Beginner's Guide to the Web Server
"Exploring Apache Tomcat: Elevate Your Web Development Experience"
🚀🚀Deployment of Apache Tomcat Webserver
Apache Tomcat is a web server
Apache Tomcat is free and open source
Apache Tomcat runs on 8080 port by default (we can also change that port )
Apache Tomcat Folder Structure
bin : It contain commands to start and stop Tomcat server (if we are using windows then we use startup.bat and shutdown.bat )(if we are using Linux OS then we use startup.sh and shutdown.sh )
conf : It contains configuration files
lib : It contains libraries (jars files)
logs : It contains servers logs files
temp : Temp files will be created here (we can also delete them )
webapps : This is called as a deployment folder
Note : We will keep all war files in webapps folder for deployment , thats why webpps called deployment folder
Working with Apache Tomcat in Linux OS
Here , the steps we need to follow for set up tomcat
Login into AWS Management Console
Create EC2 Instance (Ubuntu or any AMI)
Connect to EC2 instance using Git-bash /putty / MobaXterm
Install java software using below command
sudo apt install openjdk-11-jdk -y
- Verify the version of java installed in our machine
java -version
Note : If we have multiple java version installed then we can switch to particular version using below command
alternatives --config java
- We can download Apache Tomcat from Official Website
https://tomcat.apache.org/download-90.cgi
We can find Apache Tomcat URLs to downloads in officials website downloads page
Copy the URL of tar file and execute below command in linux machine
wget< tomcat-tar-file-url>
- After tomcat tar file got download the extract Tomcat Tar file using below command
tar -xvf<tomcat-tar-file-name>
- Go inside tomcat folder and see folder structure
$cd tomcat -folder
ls -lrt
- Go to tomcat bin directory and run tomcat server
cd bin/
./startup.sh
Note : Tomcat server runs on 8080 port by Default . Enable this port in security group as custom tcp
| Security Groups config | |
| Type : Custom TCP | |
| Portoal : TCP | |
| Port Range : 8080 | |
| Source : Custom (0.0.0.0/0) |
- Access Tomcat server from your browser
URL : http : // EC2-VM-Public-IP :8080/
Note : It should open tomcat server home page .
By default the Host Manager is only accessible from a browser running on the same machine as Tomcat .
If you wish to modify this restriction , you 'll need to edit the Host Manager 's Context.xml file.
File Location : <Tomcat >/webapps/manager/META-INF/context.xml
<context antiResourceLocking="false" privileged="true" > <valve className="org.apache.catalina.valves.RemoteAddrValve" allow".*" /> </context>Add Tomcat Users in Tomcat/conf/tomcat/tomcat-users.xml file like below /
<role rolename="manager-gui" />
<user username="tomcat" password="tomcat" roles="manager-gui" />
<role rolename="divya-gui" />
<role rolename="manager-script"/>
<user username="divya" password="divya" roles="manager-gui,divya-gui, manager-script"/>
We can change tomcat servers default port in tomcat/conf/server.xml file
When We change tomcat port number in server.xml file then we have to enable that port in security Group which is associated with our EC2 Instance .
Steps to display Maven Web Application
Create Maven Web Application
Edit index.html file like below (File Location : project-folder\src\main\webapp)
<html>
<body>
<h1><font color='red'> Welcome to divyalearn.online...!! <font></h1>
<h2> Learn here .... Lead Anywhere ...!! </h2>
<a href="https://learnwithdivya.hashnode.dev"> click Here To see My Blogs</a>
</body>
</html>
- package Maven Web Application as a war file using Maven Goals
mvn clean package
Go to Tomcat Server Admin Dashboard and click on "Manager App "
Select War file to upload and click on "Deploy" button
War file will be deployed and it will display in application
Click on Application Path (It will open the application in browser )
CONCLUSION
Stop Apache Tomcat Server
Stop EC2 instance
