how to add livy server to spark2 installed?

[#1]

I have installed spark2 in ambari without livy server. Can i add livy server to spark2 server?

I found livy server has installed, but it's still 0/0 in ambari UI?

You can add Livy Server to any of your cluster host using Ambari as followng:

Ambari UI --> Hosts (Tab) --> click on your desired Host link --> On the Hosts page you will see "Add" button 

as following

Just choose "Livy for Spark2 Server"
