# Set up a production environment

Use the following information to set up and manage your production-level full Terra node. This information has been tested against RPM-based Linux distributions only.

For information about running a validator node, see Validator Guide.

# Create a dedicated user

Although terrad does not require a super user account, during the setup process you'll need super user permission to create and modify some files. In general, to run terrad, we strongly recommend using a normal user.

# Increase the maximum files terrad can open

By default, terrad is set to open 1024 files. However, we recommend you increase this amount.

Modify /etc/security/limits.conf to increase the amount, where nofile is the number of files terrad can open.

*                soft    nofile          65535
*                hard    nofile          65535

# Configure the firewall

terrad uses the following TCP ports. Toggle their settings to fit your environment.

  • 26656: The default port for the P2P protocol. This port is used to communicate with other nodes and must be open to join a network. However, it does not have to be open to the public. For validator nodes, we recommend configuring persistent_peers and closing this port to the public.

  • 26657: The default port for the RPC protocol. Because this port is used for querying and sending transactions, it must be open for serving queries from terrad.


Do not open this port to the public unless you plan to run a public node.

  • 1317: The default port for the Lite Client Daemon (LCD), which can be executed by terrad rest-server. The LCD provides an HTTP RESTful API layer to allow applications and services to interact with your terrad instance through RPC. For usage examples, see Terra REST API (opens new window). You don't need to open this port unless you have use of it.

  • 26660: The default port for interacting with the Prometheus (opens new window) database, which can be used to monitor the environment. In the default configuration, this port is not open.

# Run the server as a daemon

terrad must be running all the time. It can be kept running in several ways, but we recommend that you register terrad as a systemd service so that it will be started automatically when the system reboots and other events occur.

# Register terrad as a service

  1. Create a service definition file in /etc/systemd/system/terrad.service, as shown in the following example:
Description=Terra Daemon

ExecStart=/data/terra/go/bin/terrad start


  1. Modify the Service section for your environment. Even if you raised the number of open files, you must include LimitNOFILE.

  2. Run systemctl daemon-reload and systemctl enable terrad.

# Control the service

Use systemctl to start, stop, and restart the service.

# Start
systemctl start terrad
# Stop
systemctl stop terrad
# Restart
systemctl restart terrad

# Access logs

Use journalctl -t to access entire logs, entire logs in reverse, and the latest and continuous log.

# Entire log
journalctl -t terrad
# Entire log reversed
journalctl -t terrad -r
# Latest and continuous
journalctl -t terrad -f
