Start the Blockchain node

Now we have everything we require to start the node, we will keep all the config files below ready on server to spin the node.

Edit config file

This is sample config file which can be edit as per business and security requirements:

Replace PRODUCER_NAME, PUBLIC_KEY and PRIVATE_KEY.

cat >etc/config.ini <<'EOT'
producer-name = PRODUCER_NAME
signature-provider=PUBLIC_KEY=KEY:PRIVATE_KEY
enable-stale-production = true

http-server-address = 0.0.0.0:8888
p2p-listen-endpoint = 0.0.0.0:9851

access-control-allow-origin = *
http-validate-host = false
contracts-console = true
verbose-http-errors = true

plugin = eosio::chain_plugin
plugin = eosio::chain_api_plugin
plugin = eosio::producer_plugin
plugin = eosio::producer_api_plugin
plugin = eosio::http_plugin
plugin = eosio::history_api_plugin
plugin = eosio::history_plugin

plugin = eosio::state_history_plugin
plugin = eosio::net_plugin

trace-history = true
chain-state-history = true
trace-history-debug-mode = true
state-history-endpoint = 0.0.0.0:8081

EOT

Change 0.0.0.0 to internal IP for security purposes.

Create log file

cat >etc/logging.json <<'EOT'
{
  "includes": [],
  "appenders": [{
      "name": "consoleout",
      "type": "console",
      "args": {
        "stream": "std_out",
        "level_colors": [{
            "level": "debug",
            "color": "green"
          },{
            "level": "warn",
            "color": "brown"
          },{
            "level": "error",
            "color": "red"
          }
        ]
      },
      "enabled": true
    }
  ],
  "loggers": [{
      "name": "default",
      "level": "warn",
      "enabled": true,
      "additivity": false,
      "appenders": [
        "consoleout"
      ]
    }
  ]
}
EOT

Edit Genesis file

This is sample genesis file, where we need to edit only three things, initial_timestamp, initial_key and initial_chain_id.

cat >etc/genesis.json <<'EOT'
{
  "initial_timestamp": "2020-06-25T00:00:00.000",
  "initial_key": "PUBLIC_KEY",
  "initial_configuration": {
    "max_block_net_usage": 1048576,
    "target_block_net_usage_pct": 1000,
    "max_transaction_net_usage": 524288,
    "base_per_transaction_net_usage": 12,
    "net_usage_leeway": 500,
    "context_free_discount_net_usage_num": 20,
    "context_free_discount_net_usage_den": 100,
    "max_block_cpu_usage": 100000,
    "target_block_cpu_usage_pct": 500,
    "max_transaction_cpu_usage": 50000,
    "min_transaction_cpu_usage": 100,
    "max_transaction_lifetime": 3600,
    "deferred_trx_expiration_window": 600,
    "max_transaction_delay": 3888000,
    "max_inline_action_size": 4096,
    "max_inline_action_depth": 4,
    "max_authority_depth": 6
  },
  "initial_chain_id": "00000000000000000000000000000000000000000000000000005368696e650a"
}

Create systemd

systemd service manager will take care of on-demand starting of daemons.

cat >etc/shine.service <<'EOT'
[Unit]
Description=Shine
[Service]
Type=simple
ExecStart=/usr/bin/nodeos --genesis-json /home/shine/etc/genesis.json --data-dir /home/shine/data/ --config-dir /home/shine/etc/ --disable-replay-opts
TimeoutStartSec=30s
TimeoutStopSec=300s
Restart=no
User=root
Group=daemon
KillMode=control-group
[Install]
WantedBy=multi-user.target
EOT

Start the node

Finally we are ready to spin the node, on entering below command we should have our new private-net node up and running and producing blocks.

sudo cp etc/shine.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable shine
sudo systemctl restart shine
