Start keosd and nodeos

Step 1: Boot Node and Wallet

Step 1.1: Start keosd

First let us start keosd:

keosd &

You should see some output that looks like this:

info  2018-11-26T06:54:24.789 thread-0  wallet_plugin.cpp:42          plugin_initialize    ] initializing wallet plugin
info  2018-11-26T06:54:24.795 thread-0  http_plugin.cpp:554           add_handler          ] add api url: /v1/keosd/stop

info  2018-11-26T06:54:24.796 thread-0  http_plugin.cpp:554           add_handler          ] add api url: /v1/wallet/get_public_keys

Press enter to continue

Troubleshooting

After entering keosd &, you may encounter this message:

"3120000 wallet_exception: Wallet exception Failed to lock access to wallet directory; is another keosd running?"

This is because another instance of keosd process might be running in the background. Kill all instances by pkill keosd and rerun keosd &.

Step 1.2: Start nodeos

Start nodeos now:

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

These settings accomplish the following:

1. Run Nodeos. This command loads all the basic plugins, set the server address, enable CORS and add some contract debugging and logging.

2. Enable CORS with no restrictions (*) and development logging

危险

In the above configuration, CORS is enabled for * for development purposes only, you should never enable CORS for * on a node that is publicly accessible!

Troubleshooting

After starting nodeos, if you see an error message similar to "Database dirty flag set (likely due to unclean shutdown): replay required", try to start nodeos with --replay-blockchain. More details on troubleshooting nodeos can be found here.

Step 2: Check the installation

Step 2.1: Check that Nodeos is Producing Blocks

Run the following command

tail -f nodeos.log

You should see some output in the console that looks like this:

Press ctrl + c to close the log

Step 2.2: Check the Wallet

Open the shell and run the cleos command to list available wallets. We will talk more about wallets in the future. For now, we need to validate the installation and see that the command line client cleos is working as intended.

cleos wallet list

You should see a response with an empty list of wallets:

Wallets:
[]

From this point forward, you'll be executing commands from your local system (Linux or Mac)

Step 2.3: Check Nodeos endpoints

This will check that the RPC API is working correctly, pick one.

1. Check the get_info endpoint provided by the chain_api_plugin in your browser: http://localhost:8888/v1/chain/get_info
2. Check the same thing, but in the console on your host machine

curl http://localhost:8888/v1/chain/get_info
