Allow port 8080 on the AWS Security group of Jenkins Server to access it from outside. I have opened the port 8080 for everyone, but you can allow it for your network only.

Access Jenkins Server on Web Browser

Access Jenkins Public IP on port 8080 on a web browser.

      https://JenkinsServerPublicIP:8080

 

Copy the following path as shown in the above screenshot to get the temporary password for Jenkins login. Use cat command to see the password. Use this temporary password to login to Jenkins Server on web browser first time.

$ cat   /var/lib/jenkins/secrets/initialAdminPassword

After login, choose any of the following options. I will recommend choosing ” Install suggested plugins”

 

Create First Admin User and set a password. Note down this credential to log in to Jenkins Server next time.

 

The following page comes, which will show your Jenkins URL. Click “Save and Finish”

As soon as you click on ” Save and Finish” it will redirect you to the Jenkins URL. Now Jenkins Server is ready to use and create jobs.
