0.96 -> Hello Everyone ā¦ Welcome back to our channel.
3.51 -> Hope everyone is doing good.
4.51 -> In this video, we are going to see how to
setup jenkins on Ubuntu ( which is one of
12.08 -> the Linux version ) and on Windows.
16.01 -> Maybe a question would arise as to why on
ubuntu ? Well, if you take DevOps infrastructure
23.13 -> of most of the teams ā¦ more than 90% of
them will have their Jenkins running on Linux
29.499 -> Operating System like CentOS or Red Hat Enterprise
Linux or Ubuntu.
34.89 -> The reason behind this is Linux comes with
great benefits like scalability, flexibility
40.989 -> and easy to install packages etc.
45.829 -> Also, the security feature of Linux is a major
plus.
50.09 -> So, in order to understand DevOps completely
one must have good Linux skills too.
57.26 -> With that being said ā¦ let's begin
59.149 -> So, first we are going to start with Ubuntu.
67.659 -> If you are already running any linux version
on your local then you can directly skip to
76.25 -> Jenkins installation step which is marked
in the timestamp.
80.89 -> Now, If you are running Windows on your local
machine then there are some pre-requisites
86.909 -> which needs to be installed first in order
to launch a ubuntu machine on top of your
92.64 -> windows machine.
93.75 -> First one is Oracle Virtual Box and the second
is Vagrant.
100.799 -> So, let's start installing Virtual Box.
116.95 -> Select Windows Host and you can see an executable
file will be downloaded.
123.28 -> Once the download is complete, just run the
exe file, click 'Next' and approve the license
131.16 -> terms.
132.83 -> The installation is just simple as that.
137.5 -> Now, we are going to install Vagrant.
152.66 -> Download the msi file and follow the standard
installation procedure same as earlier.
161.28 -> Once the installation of Virtual Box is complete
you should be able to see this screen.
166.58 -> You can see currently we don't have any machines
running.
171.2 -> If I click 'Add' it will ask me to import
an vbox file.
179.3 -> Finding an appropriate box and downloading
it is somewhat lengthy.
183.88 -> So, that's where Vagrant helps us.
190.45 -> By running a couple of commands , we can launch
an ubuntu on the Virtual box.
196.72 -> Create a new folder in your local drive where
you want to store the ubuntu box.
206.86 -> If you have git installed, then right-click
and select Git bash.
212.9 -> I, personally feel more comfortable with Git
bash.
216.59 -> If you donāt have Git then no worries, you
can execute the commands from your windows
222.041 -> command prompt terminal
We are going to check if vagrant is correctly
226.37 -> installed ā¦ and we can see that vagrant
is installed.
231.92 -> Now, visit the Vagrant site again, go to 'Find
Boxes' and search for ubuntu box.
243.62 -> You can switch to 'new' tab and execute the
same commands from your terminal
267.03 -> After executing the initialization command
, we can see that a vagrant file is generated
275.89 -> in the folder.
278.919 -> I'm going to open it to check some configurations.
285.379 -> This is the one configuration which we are
going to uncomment and modify the guest port
297.96 -> to 8080 and we will see soon why this needed.
303.15 -> Save the file and exit.
305.909 -> Now execute the vagrant up command . As we
are bringing up the ubuntu box for the first
311.409 -> time it will take some time to complete
316.129 -> After the installation is complete, you should
see this window which displays all the configurations
322.47 -> of our ubuntu box.
324.129 -> Now, we will ssh into the box
If we observe the above output, we can see
332.65 -> the 'vagrant' user generated along with ssh
key.
338.629 -> Also this command is easier if we compare
with our usual ssh command that we use on
344.159 -> Linux server.
346.24 -> Now we have successfully logged in to our
ubuntu box
356.34 -> As our Virtualbox installation is complete,
we can see that it is running our ubuntu box
362.469 -> launched by vagrant
366.169 -> Now , to install jenkins we are going to follow
the official documentation as it is.
375.389 -> We can see the Minimum requirements mentioned
for the Jenkins to run smoothly
385.189 -> Installing Java is mandatory as Jenkins can't
run without Java
394.439 -> I'm going to check the java version on the
ubuntu box.
399.77 -> Looks like we don't have any version installed.
403.21 -> Currently Jenkins supports only JDK8 and JDK11
and that too JDK 11 is compatible with Jenkins
411.591 -> 2.164 and above
So, if you donāt have any java installed
417.08 -> on your ubuntu then execute the following
command to check for available jdk versions
425.29 -> Here we can see that, only jdk11 is available
on my ubuntu box ā¦ so, I'm going to install
430.99 -> jdk11 on my ubuntu.
432.919 -> So, whatever ubuntu box that you have selected
from vagrant, check if it has jdk8 or jdk11.
439.009 -> If not then destroy the box and pick the correct
one else you will run into errors while installing
445.74 -> Jenkins.
448.319 -> JDK installation usually takes more time.
453.009 -> So, let's wait
Our jdk installation is finally complete,
468.559 -> I'm checking for the java version again.
476.139 -> Now we can see that jdk11 is installed on
our ubuntu
486.599 -> I'm just executing the steps from the official
documentation here
492.62 -> Jenkins installation also takes time ā¦ so
let's wait
509.389 -> We can now see that Jenkins has been successfully
installed
512.65 -> Now, let's try to access our jenkins through
browser.
520.91 -> And Jenkins is showing up
Earlier we have enabled port forward configuration
526.711 -> in vagrant file.
528.63 -> This configuration helps us to access the
Jenkins installed on Virtual box from our
534.39 -> local windows machine browser.
535.82 -> So, that is the reason we have to edit it
543.63 -> Let's see how to install jenkins on Windows
First we need to check the java version in
551.37 -> my local machine.
552.37 -> As we can see Java 1.8 is already installed
in my local.
557.32 -> So, I will not be doing any new installation
here.
561.59 -> I'm just going to get the path where the java
is installed
567.07 -> If you couldn't find any jdk on your machine
then download the jdk from the link given
571.97 -> in description
The installation of jdk will be straight-forward.
578.96 -> Only one thing to remember is please copy
the java path while installing the jdk because
585.66 -> we need it during jenkins installation
Also remember to pick correct jdk and jenkins
592.77 -> combination i.e, if you are installing jdk11
then you should pick >= Jenkins 2.164
600.51 -> Now, I'm going to download the jenkins 2.232
from the website and start installing it
609.54 -> Click on Next and when it prompts to enter
the java path, paste the one which you have
635.4 -> copied earlier and click 'Next'
Finish your installation and then your browser
643.08 -> should automatically open up localhost
Give it sometime and once the installation
651.1 -> is complete then you should see this screen
Retrieve the admin password from the below
658.4 -> directory and proceed further
664.38 -> We have retrieved our admin password from
the ubuntu box as well.
675.06 -> Once the password is authenticated, we can
see that Jenkins prompts for the plugin installation.
685.8 -> As Jenkins is a CI tool, it helps us to integrate
with other tools easily and this can be done
691.95 -> by installing respective plugins
For now, we are going to install suggested
698.76 -> plugins
707.48 -> Once the plugins are installed , we can see
in the next window which prompts to create
713.16 -> our first user.
715.33 -> I'm just going to fill out these details.
719 -> Now, we can see that we can modify the jenkins
URL as per our need.
725.46 -> Let's complete the setup
Now Our Jenkins installation is finally complete
732.98 -> and it is running !
734.43 -> Let's create our first jenkins job.
740.71 -> We can see that there are different types
of jobs like freestyle, pipeline and others
747.76 -> etc.
748.76 -> We will discuss about each of them as we progress
through this series.
753.13 -> For now, We are just going to build a job
which executes a shell command.
764.81 -> Select the name for the job
Let's add some description
778.15 -> Next, we can see SCM which needs to be configured
if we are pulling the code from Git or bitbucket
792.5 -> We have many Build Triggers, which triggers
our jenkins job accordingly
797.13 -> Now, for the actual 'Build' step , we can
see, we can execute Ant or Gradle or Maven.
807.31 -> If we add more plugins we can see them appearing
here respectively
813.04 -> Let's select 'Execute Shell' and print a simple
message
818.21 -> Yeah, now we can see that our build is successful
and our job has been successfully executed.
837.44 -> So, with this video, we have covered the installation
of Jenkins on Ubuntu and Windows and building
844.07 -> your first job.
845.63 -> Try it out on your local machines and if you
encounter any errors, please reach out to
851.12 -> us in the 'Comments' section.
853.99 -> We will try to address it as quickly as possible
859.06 -> In our next sessions we will explore more
about Jenkins like building a project by pulling
865.23 -> the code from SCM, Pipeline jobs, Jenkins
administration etc.
