To start a local WAX node on your development server:

  1. From the command line, enter the following to initialize keosd.

    keosd &

    The console prints the following information:

  2. Next, paste the following to start producing blocks:

    nodeos -e -p eosio \
--plugin eosio::producer_plugin \
--plugin eosio::chain_api_plugin \
--plugin eosio::http_plugin \
--access-control-allow-origin='*' \
--contracts-console \
--http-validate-host=false \
--verbose-http-errors >> nodeos.log 2>&1 &

    This will initialize all of the basic plugins, set the server address (yours), and add contract debugging and logging.

    Important: The --access-control-allow-origin='*' parameter enables Cross-Origin Resource Sharing (CORS). Never enable this for a public node.
    {: .label .label-yellow }

    When the command completes, the console prints out a number, similar to the following:

    [2] 4529.

  3. To verify that nodeos is producing blocks, from the command line, use the tail command to view the log:

    tail -f nodeos.log

    The console prints your block information:

    info  2019-07-16T21:36:14.501 thread-0  producer_plugin.cpp:1597      produce_block        ] Produced block 0000043f8f7c37a1... #1087 @ 2019-07-16T21:36:14.500 signed by eosio [trxs: 0, lib: 1086, confirmed: 0]
info  2019-07-16T21:36:15.001 thread-0  producer_plugin.cpp:1597      produce_block        ] Produced block 00000440315e6c27... #1088 @ 2019-07-16T21:36:15.000 signed by eosio [trxs: 0, lib: 1087, confirmed: 0]

    Tip: Notice the "signed by eosio" signature - this is the local system account. {: .label .label-yellow }

You're now running a local WAX node on your development server. Press Ctrl + c to close the log (nodeos will continue to run in the background).

Stop a Local Node

To cleanly stop nodeos:

  1. From the command line, run pkill:

    pkill nodeos

  2. To verify that nodeos is no longer producing blocks, run the tail command to view the log:

    tail -f nodeos.log

    On the last line, the console prints: "nodeos successfully exiting."
