Let Us Install Jenkins 1.617 in Ubuntu 15.04
Download Jenkins

Install the Oracle Java 8 JDK(JRE/JDK)
Type 'su' and the update "sudo apt-get update" then below steps follow :-
Step1 :- sudo apt-get install openjdk-8-jre
Step2 :- sudo apt-get install openjdk-8-jdk
Step3 :- java -version
Download Java JDK 8 From Oracle Website

Installing Jenkins
Step4 :- wget -q -O - https://jenkins-ci.org/debian/jenkins-ci.org.key | sudo apt-key add -
Step5 :- sudo sh -c 'echo deb http://pkg.jenkins-ci.org/debian binary/ > /etc/apt/sources.list.d/jenkins.list'
Step6 :- sudo apt-get update
Step7 :- sudo apt-get install jenkins
Upgrade to Latest Version
If available for latest version you can update
Step8 :- sudo apt-get update
Step9 :- sudo apt-get install jenkins
What does this package do?
Jenkins will be launched as a daemon up on start. See /etc/init.d/jenkins for more details.
The 'jenkins' user is created to run this service.
Log file will be placed in /var/log/jenkins/jenkins.log. Check this file if you are troubleshooting Jenkins.
/etc/default/jenkins will capture configuration parameters for the launch like e.g JENKINS_HOME
By default, Jenkins listen on port 8080. Access this port with your browser to start configuration.
The Ubuntu Jenkins maintainer also maintains for deployment in clouds.
Step11 :- juju deploy jenkins
Step12 :- juju deploy -n 5 jenkins-slave
Step13 :- juju add-relation jenkins jenkins-slave
The default password for the 'admin' account will be auto-generated. You can set it using:
Step14 :- juju set jenkins password=mypassword
Always change it this way - this account is used by the charm to manage slave configuration. Then feel free to expose your jenkins master:
Step15 :- juju expose jenkins
Setting up an Apache Proxy for port 80 -> 8080
This configuration will setup Apache2 to proxy port 80 to 8080 so that you can keep Jenkins on 8080.
Step16 :- sudo aptitude install apache2
Step17 :- sudo a2enmod proxy
Step18 :- sudo a2enmod proxy_http
Note :- do not do this next command if you already have virtual hosting setup that depends on the default site.
Step19 :- sudo a2dissite default
Create a file called jenkins.conf in /etc/apache2/sites-available
<VirtualHost *:80>
ServerAdmin webmaster@localhost
ServerName cloudnetwork.in
ServerAlias cloud
ProxyRequests Off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPreserveHost on
ProxyPass / http://localhost:8080/ nocanon
AllowEncodedSlashes NoDecode
</VirtualHost>
Step21 :- sudo a2ensite jenkins
Step22 :- sudo apache2ctl restart
Setting up an Nginx Proxy for port 80 -> 8080
This configuration will setup Nginx to proxy port 80 to 8080 so that you can keep Jenkins on 8080.
Step22 :- Install Nginx.
Step23 :- sudo aptitude -y install nginx
Remove default configuration.
Step24 :- cd /etc/nginx/sites-available
Step25 :- sudo rm default ../sites-enabled/default
Create new configuration for Jenkins.
Note: Sometimes your permissions (umask, etc) might be setup such that this won't work.
Create the file somewhere else then copy it into place if you run into that problem
Step27 :- sudo cat > jenkins
upstream app_server {
server 127.0.0.1:8080 fail_timeout=0;
}
server {
listen 80;
listen [::]:80 default ipv6only=on;
server_name cloudnetwork.in
location / {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
if (!-f $request_filename) {
proxy_pass http://app_server;
break;
}
}
}
Hit CTRL + D to finish writing the file
Link your configuration from sites-available to sites-enabled:
Step28 :- sudo ln -s /etc/nginx/sites-available/jenkins /etc/nginx/sites-enabled/
Step29 :- Restart Nginx
Step30 :- sudo service nginx restart
Where to go from here?
(http://myserver/jenkins/ instead of http://myserver:8080/)
