suggest_brain_key

• Copy the JSON output and save it to secure locations

{
"brain_priv_key": "FULK DEBUG EARTH IMAGINE BABBLE POPIFY PREFEED EMBIND FOREPAW KAHILI ...",
"wif_priv_key": "5JsPmgU1dfKu8SHWAWkBKw1XGz97Kwz4DLwgm2bSz99qtFqTAkp", 
"pub_key": "STM73jgNRFLTKSTaGWv8QfXzSopUZBsQGmrECWPvpnemjyAcBfzAc"
}

• Never share the "wif_private_key"
• You will need your wif private key for the config.ini file in a minute.
• this is a good time to load YOUR key in your cli_wallet terminal window like this:

import_key 5JsPmgU1dfKu8SHWAWkBKw1XGz97Kwz4DLwgm2bSz99qtFqTAkp

Exit cli_wallet terminal:

ctrl + c

This is a good time to pick your account/miner name. Remember, account names must be all lower case, less than 15 characters, and start with a letter. For instance, lets say you pick account name george1234 as your account name. Check if the account already exists by going to:

https://steemit.com/@george1234

If you get an error like this:

Server error (500) 10 assert_exception: Assert Exception itr != accounts_by_name.end(): Unable to find account 'george1234'. Did you forget to add a record for it? {"acct":"george1234"} th_a database.cpp:313 get_account

Then you are in luck and the account name is available to claim, try another until you stop getting the error.

Finally, you have what you need to edit your config.ini file and start mining.

Open file with your favorite linux text editor: steem/programs/steemd/witness_node_data_dir/config.ini

Replace george1234 with your account name and this wif key 5JsPmgU1dfKu8SHWAWkBKw1XGz97Kwz4DLwgm2bSz99qtFqTAkp with yours.

# Number of threads to use for proof of work mining

mining-threads = 1

these are the parts you change, leave the rest as is and save your config file then go back to the steemd terminal window (hopefully it synced by now):

ctrl + c

will stop steemd and then restart it with the following line:

./steemd --rpc-endpoint

It should start mining as soon as it catches up to the latest block. Once a block is mined, the account name will be claimed. You can then run the following commands in CLI_wallet. Remember to change george1234 to your account name:

unlocked >>> get_account "george1234"  

unlocked >>> list_my_accounts  

unlocked >>> vote_for_witness george1234 joseph true true 

unlocked >>> vote george1234 "joseph" "mining-steem-for-dummies" 100 true
