Install/Configure Ranger Admin:

1. lay Lay down the binaries into appropriate places.  

• cd /usr/local

• sudo tar zxf ~/dev/ranger/target/ranger-0.4.0-admin.tar.gz

• sudo ln -s ranger-0.4.0-admin ranger-admin
2. Open install.properties in ranger root folder
3. Verify the root password that you had picked while installing mysql.  I had chosen root so the relevant section in my install.properties file looks as follows
4. The install process would create a couple of users in the database for storing administration and audit information, pick passwords for those too.  With my choices here’s how the relevant sections in the install.properties file look now.
5.  Ranger allows you to get fancier with security and authentication mode different authentication modes but for now let’s just leave rest of the things in this install.properties file as they are. 

6. Once all the required properties are updated, 

       Execute : ./setup.sh
       Execute : ./set_globals.sh
       This will install the Ranger service.

7. create a valid symlink in /usr/bin/ for start/stop of ranger admin
       cd /usr/bin
       ln -sf /usr/local/ranger-admin/ews/start-ranger-admin.sh ranger-admin-start
       ln -sf /usr/local/ranger-admin/ews/stop-ranger-admin.sh ranger-admin-stop

8. update ranger-admin service file to link to the start and stop scripts
       vim /etc/init.d/ranger-admin ( Update the Start and Stop commands to point to the created symlinks )

9. Start the Ranger Admin
        service ranger-admin start

10. You can verify by visiting the external URL of the server using browser, for example :
        http://<Host Address>:6080/
