| How To Install Jenkins on Ubuntu 16.04 Box |
Introduction
Jenkins is an open source automation server intended to automate repetitive technical tasks involved in the continuous integration and delivery of software. Jenkins is Java-based and can be installed from Ubuntu packages or by downloading and running its Web application ARchive (WAR) file. For the latter, it is only relevant to Java Servlet Container (e.g. Apache Tomcat) and the installation process should be good for any OS including Ubuntu.
Prerequisites
Tomcat 8 (with Java 8) which is running on Ubuntu 16.04 box
At least 1 GB of RAM

WinSCP to your Ubuntu 16.04 box
Upload jenkins.war to /tmp --> (Rights: rw-rw-r-- Owner: administrator)
PuTTy to Ubuntu 16.04 box
$ cd /tmp
$ sudo cp jenkins.war /opt/tomcat/apache-tomcat-8.5.23/webapps/ --> (Rights: rw-r--r-- Owner: root)
The service should be automatically deployed under folder ./webapps/jenkins (Rights: rwxr-x--- Owner: administrator)
The built-in administrative user password can be found by:
$ cat /opt/tomcat/apache-tomcat-8.5.23/logs/catalina.out
*************************************************************
Jenkins initial setup is required. An admin user has been created and a password generated.
Please use the following password to proceed to installation:

http://10.11.12.13:8080/jenkins --> http://10.11.12.13:8080/jenkins/login?from=%2Fjenkins%2F
Unlock Jenkins
To ensure Jenkins is securely set up by the administrator, a password has been written to the log (not sure where to find it?) and this file on the server:
/home/administrator/.jenkins/secrets/initialAdminPassword
Please copy the password from either location and paste it below.
Administrator password
xxxxxxxx

Customize Jenkins
Plugins extend Jenkins with additional features to support many different needs.
Select Suggested Plugins:
(If your JVM has limited RAM resource (e.g. ~512MB), you may experience the OutOfMemory error at the plugins loading stage)
