Summary

Click on Launch instance on right side box

Once after clicking on Launch instance , we redirects to another page, in that page we can see Luanch status and Launch logs as success,

Next click on Instance ID in the brackets to connect with that instance

Step 3 – Connecting to Instance using .pem SSH key through SSH Terminal :

(Terminal : if you don’t have the terminal on windows , just to go to Microsoft store(which is preinstalled on windows 10 and 11, Search for Windows Terminal and  install the Windows Terminal)

Wait until the checks completed , below screenshot shows your , instance state and status checks  with pending status and Wait up to 2-5 minutes, keep refreshing until you get the responses like below

Next, Select the instance  by selecting tick at its left side and click on connect button on top

We can connect to EC2 instance with below option

• • EC2 Instance Connect

• • Session Manager

• • SSH client

• • EC2 serial console

But in among them we use SSH client option to connect

Choose SSH, copy the Example: command

Check , which location the pem key is downloaded in file explorer

Open Terminal by searching on windows

Run the below commands:

	Moving to downloads directory	cd downloads
	Paste the Example command here	ssh -i “LP1_ubtuntu-apache-tomcat-server-keypair.pem” ubuntu@ec2-35-174-205-62.compute-1.amazonaws.com
		Press Enter

Now, we are connected to ubuntu EC2.

Vi Editor :

On Next steps we use VI Editor, to edit the file on Terminals, it is a file editor, we need to use some commands to edit the files .

To Read/Get More info by visiting this web page :

https://sagar5.in/linux/linux-vi-editor/

But right now we need basic information so just try to follow this

Note	After running vim commands, file opens , to edit the file Press I andTo save the file first press the ESC button , next type :wq! , press Enter

Step 8	Making public accessible by commenting Remoteaddressvalue for manager
command	sudo vim /usr/share/apache-tomcat/webapps/manager/META-INF/context.xml
Comment this line	<!–<Valve className=”org.apache.catalina.valves.RemoteAddrValve”  allow=”127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1″ />–>

Terminal Response :

Step 9	Making public accessible by commenting Remoteaddressvalue for host-manager
command	sudo vim /usr/share/apache-tomcat/webapps/host-manager/META-INF/context.xml
Comment this line	<!–<Valve className=”org.apache.catalina.valves.RemoteAddrValve”  allow=”127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1″ />–>

Terminal Response :

Step 10	Adding Tomcat username and password by editing tomcat-users.xml file
command	sudo vim /usr/share/apache-tomcat/conf/tomcat-users.xml

Terminal Response :

Step 14

Copy the public IP of EC2 by selecting it

Step 15

Open the public ip at browser by adding port 8080

Before opening it

Add a entry in Instance security group with

(i) Select instance, go security tab at bottom side and Click on Security group

(ii) Click on Edit inbound rules

(iii) Add Rule :

Type : Custom TCP , Port range : 8080 , Source : Anywhere – IPv4 , Next click on Save rules

Step 5: Login & Verify

Now open the Public ip with port : Now it is working

Now we can login in to Tomcat using tomcat-users.xml credentials

Admin user:

Username : AdminUser

&

Password : AdminUser@2023#

Manager user

Username : AdminManager

&

Password : AdminManager@2023#

Click on Manager App : Login with credentials of Manager
