- Go to browser and enter public IP Address of EC2 instance.
http:3.54.8.89:8080
If you do not see anything on browser then AWS default security group might turned off port '8080' which jenkins run on. You need to enable that.
- open browser and type ip address of instance along with port number .
http:3.54.8.89:8080
Go to "Mobaxterm" and view password --> type
cat /var/lib/jenkins/secrets/initialAdminPasswordgo to browser, copy & paste password onto admin field and click "continue"
There you go, you have successfully installed the jenkins CI/CD tool onto Ubuntu EC2 instance all by yourself. Congrats.
