Install & Configure Web Application KodeKloud Engineer Task Success

Question :  xFusionCorp Industries is planning to host two static websites on their infra in Stratos Datacenter. The development of these websites is still in -progress, but we want to get the servers ready. The storage server has a shared directory /data that is mounted on each app host under /var/www/html directory. Please perform the following steps to accomplish the task:

a. Install httpd package and dependencies on all app hosts.

b. Apache should serve on port 8080 within the apps.

c. There are two website's backups /home/thor/news and /home/thor/cluster on jump_host. Set them up on Apache in a way that news should work on link http://<<lb-url>>/ecommerce/ and cluster should work on link http://<<lb-url>>/cluster. (do not worry about load balancer configuration, as its already configured).

d. You can access the website on LBR link; to do so click on the + button on top of your terminal, select the option Select port to view on Host 1, and after adding port 80 click on Display Port.

Please Note :-  Perform the below commands based on your question  server,  user name & other details might differ as per the task.
