There is your hint, the index script can't connect to the explorer.
Make sure your iquidus is running before trying to index.

how to run iquidus please tell me

Follow the readme at https://github.com/iquidus/explorer it cointains step-by-step instructions to install and run the iquidus explorer. Once it is running you can start the indexing script.

i am typing
./newerad -daemon -reindex -txindex

Error: An error occurred while setting up the RPC port 49110 for listening on IPv4: bind: Address already in use

Your coin daemon seems to be already running, try connecting with either newerad getinfo or newera-cli getinfo (I don't know which is valid for that specific coin).
