Installing Jenkins on Ubuntu

Question

I am trying to install Jenkins on ubuntu 11.04

I have installed Oracle Java

$:~$ java -version
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) Server VM (build 25.5-b02, mixed mode)
$:~$ javac -version
javac 1.8.0_05
$:~$

$ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/lib/jvm/jdk1.8.0_05/bin:/usr/lib/hadoop/hadoop-1.2.0/bin/:/usr/lib/pig/pig-0.12.0/bin:/usr/lib/hive/hive-0.11.0/bin:/usr/lib/hbase/hbase-0.94.8/bin
$:~$ echo $JAVA_HOME
/usr/lib/jvm/jdk1.8.0_05

When I try to install, I have some dependency issues..

$ sudo apt-get install jenkins

Steps to install jenkins and view in browser with IP:-

1. sudo apt update
2. sudo apt search jdk --to search jdk
3. sudo install openjdk-8-jre
4. sudo install openjdk-8-jre-headless

5. wget -q -O - https://pkg.jenkins.io/debian/jenkins.io.key | sudo apt-key add -

6. add below line in the file /etc/apt/sources.list: sudo nano /etc/apt/sources.list OR sudo vi /etc/apt/sources.list

   Add this below link at the end of editing document.

   deb https://pkg.jenkins.io/debian binary/

7. Update your local package index

   sudo apt-get update

8. Install jenkins now

   sudo apt install jenkins

9. start jenkins service

   sudo systemctl start jenkins

10. Enable the jenkins service

    sudo systemctl enable jenkins

    Now jenkins installed in your system. If are following these steps you are good to go. heat localhost:8080 in the browser. because jenkins works on 8080 by default. you can change it's port to others.

    Now if are using google cloud then there is one more step.

11. Firewall rule details (Add firewall rule to enable ip and tcp 8080 port) That's that now if you open in browser http://<your-ip>:8080 jenkins will open and ask you to view the password which give location on the ui.
