Enable the Jenkins Service
|
1 |
ubuntu@ip-172-31-13-137:~$sudo systemctl enable jenkins<br /> |
7. Access the Jenkins
we can access the Jenkins through web page.
Jenkins default port is 8080.
Open browser we need to give Public IP of Jenkins Machine:8080 for accessing Jenkins.
Copy the Public IP of Jenkins
Search Public IP:8080 in browser
We can see the Jenkins page and we need to unlock Jenkins.
Unlock Jenkins
If you want to unlock jenkins we need to provide password.
we will get password by using path ” /var/lib/jenkins/secrets/initialAdminPassword”.
Get Password
Go the path “/var/lib/jenkins/secrets” and open the file “initialAdminPassword” and copy the password.
|
1 2 |
ubuntu@ip-172-31-13-137:~$ sudo cat /var/lib/jenkins/secrets/initialAdminPassword c00a82fdff7747bdbdf7c3a35bd8db9c |
Provide password which was copied and click on continue.
Select Install suggested plugins.
when you select install suggested plugins you will get so many default plugins.
Once select “Install suggested plugins”, it is going to install all default plugins.
It may take 10 minutes to complete.
Create First Admin User
Provide required things to create admin user and click on save and continue.
we can see Jenkins URL “http://13.233.117.219:8080/” and Save and Finish.
Jenkins is ready to use and click on Start using Jenkins.
Finally, we can see the dashboard of Jenkins.
