Configure general settings

The following information describes the most important node configuration settings found in the ~/.terra/config/ directory. It is recommended that you update these settings with your own information.

Structure of .terra/config


_8
~/.terra/config
_8
│-- addrbook.json # a registry of peers to connect to
_8
│-- app.toml # terrad configuration file
_8
│-- client.toml # configurations for the cli wallet (ex terracli)
_8
│-- config.toml # Tendermint configuration file
_8
│-- genesis.json # gensesis transactions
_8
│-- node_key.json # private key used for node authentication in the p2p protocol (its corresponding public key is the nodeid)
_8
└-- priv_validator_key.json # key used by the validator on the node to sign blocks

Initialize and configure moniker​

Initialize the node with a human-readable name:


_1
terrad init <your_custom_moniker> # ex., terrad init validator-joes-node

☢️Moniker characters

Monikers can only contain ASCII characters. Using Unicode characters will render your node unreachable by other peers in the network.

You can update your node's moniker by editing the moniker field in ~/.terra/config/config.toml.

Update minimum gas prices​

  1. Open ~/.terra/config/app.toml.

  2. Modify minimum-gas-prices and set the minimum price of gas a validator will accept to validate a transaction and to prevent spam.

The recommended setting is:

minimum-gas-prices = "0.015uluna"

Example:


_3
# The minimum gas prices a validator is willing to accept for processing a
_3
# transaction.
_3
minimum-gas-prices = "0.015uluna"

Start the light client daemon (LCD)​

For information about the available Terra REST API endpoints, see the Swagger documentation. To enable the REST API and Swagger, and to start the LCD, complete the following steps:

  1. Open ~/.terra/config/app.toml.

  2. Locate the API Configuration section ([api]).

  3. Change enable = false to enable = true.


_2
# Enable defines if the API server should be enabled.
_2
enable = true

  1. Optional: Swagger defines if swagger documentation should automatically be registered. To enable Swagger, change swagger = false to swagger = true.

_1
swagger = true

  1. Restart the service via systemctl restart terrad. Once restarted, the LCD will be available (by default on port 127.0.0.1:1317).

Set up external_address in config.toml​

In order to be added to the address book in seed nodes, you need to configure external_address in config.toml. This addition will prevent continuous reconnections. The default P2P_PORT is 26656.


_1
sed -i -e 's/external_address = \"\"/external_address = \"'$(curl httpbin.org/ip | jq -r .origin)':26656\"/g' ~/.terra/config/config.toml
