You have to first enable "miner" API with --rpcapi option and then start miner. To enable this API, use:

$ geth --rpc --rpcapi "eth,miner,net,web3"

Now you won't get this error.

I am not able to add peer using addPeer command. Even after using the command you told. Let me know what I can do

This is because addPeer is a function that comes under admin option of rpcapi. To use it, you will have to use the following command:

$ geth --rpc --rpcapi "eth,miner,net,web3,admin"
