We are going to discuss Installing Jenkins today. We will be focusing on installing it on Tomcat server as a servlet, and tomcat will act as a container for Jenkins.<\/p>\n\n\n\n

Step 1 : <\/strong>Check java 1.8 is installed in the system.<\/p>\n\n\n\n

Step 2:<\/strong> Installing Tomcat server.<\/p>\n\n\n\n

Tomcat server of your choice can be downloaded from below link :
https:\/\/tomcat.apache.org\/download-90.cgi<\/a> – I downloaded core zipped version for my mac. which was 11mb in size.<\/p>\n\n\n\n

Create a new folder and place the downloaded zip file there and Unzip it:<\/p>\n\n\n\n

For unzipping u can type :<\/p>\n\n\n\n

>\/ unzip <file.name><\/p>\n\n\n\n

\"\"
extracting zip file<\/figcaption><\/figure>\n\n\n\n

Now, goto \/Users\/penguin\/tomcat\/apache-tomcat-9.0.31\/bin , for you path could be different depending upon the time and version which you are using for tomcat but It could be pretty much similar in any case :<\/p>\n\n\n\n

when you will run ls command there you will see something similar<\/p>\n\n\n\n

\"\"
path to bin directory<\/figcaption><\/figure>\n\n\n\n

Run, sh startup.sh command which should start tomcat for you.<\/p>\n\n\n\n

\"\"

If you are getting a permission error like below :<\/p>\n\n\n\n

permission error on catalina.sh<\/figcaption><\/figure>\n\n\n\n

Run, chmod +x catalina.sh<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

You should be good post this goto : localhost:8080 you will see something line this , Step 2 completed, phew !!!!<\/p>\n\n\n\n

Step 3: <\/strong>Installing Jenkins as servlet on Tomcat as container.<\/p>\n\n\n\n

First let’s download latest Jar of Jenkins, from here<\/a>. Once done place the jar in \/Users\/penguin\/tomcat\/apache-tomcat-9.0.31\/webapps<\/em><\/p>\n\n\n\n

Make sure, your tomcat server is up and running, as we will copy the jar file Tomcat will start the jar automatically and a jenkins folder will get created in the webapps directory – which will be something like below – <\/p>\n\n\n\n

\"\"
before and after – new jenkins folder created.<\/figcaption><\/figure>\n\n\n\n

Now, let try accessing jenkins – try going to localhost:8080\/jenkins<\/p>\n\n\n\n

If you see something like this – you are done !!! thanks for holding your nerves and following all steps – if you see any error feel free to reach out to me.<\/p>\n\n\n\n
