Eos: nodeos fail to start in local testnet

[Npizza]

I followed the instractions from the local enviroment page and when run the:
./nodeos -e -p eosio --plugin eosio::wallet_api_plugin --plugin eosio::chain_api_plugin --plugin eosio::account_history_api_plugin
I get this error:
3124424ms thread-0 main.cpp:97 main ] Throw location unknown (consider using BOOST_THROW_EXCEPTION) Dynamic exception type: boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::system::system_error> > std::exception::what: bind: Address already in use

what I am doing wrong?

nodeos is already running. First pkill nodeos before launching another one with the same listen port number.

Thank you.It worked.It seems that when you install it is running to the background
