You have to run the start command of the oozie to access it via web. As I can see from the console log attached that you have not run the start command of oozie. You have to follow the below steps to start the oozie:
Change the directory to Oozie and start it.
$ cd /usr/lib/oozie-4.0.0/
$ ./bin/oozie-start.sh
Once the service is started you can access it via web
