Change IP or Hostname

If you need to change the IP address or hostname of a node or a cluster after TigerGraph is up and running, you can change them by running the following commands as the tigergraph admin user.

  1. Pause your database operations.

  2. Shut down services, as shown below:

gadmin init etcd
gadmin stop all

The command gadmin init etcd initializes the etcd component of TigerGraph, while gadmin stop all stops all running TigerGraph services.

  1. Make your IP changes (outside of TigerGraph).

  2. Apply the new IP/hostnames, using the two commands below.

The first command applies the updated TigerGraph host list from '~/.tg.cfg' to define cluster nodes for deployment.

The second command initializes the TigerGraph cluster without stopping running services (--skip-stop) and also initializes etcd, the distributed key-value store for configuration and coordination (--init-etcd).

After change IP/hostname(s):
gadmin config entry System.HostList --file ~/.tg.cfg  # Edit IP/hostname here
gadmin init cluster --skip-stop --init-etcd
