[7.0 Error] CANNOT start after changing IP in 7.0 (code=exited, status=78)

[cosloli (Yang Juecheng)]

At first I used the default setting, and everything works fine.

But when I change the host IP in elasticsearch.yml, it just can't launch:

The config I changed:

I can launch ES succesfully in 1.7.3 version with changed IP, so I don't think it's a firewall problem. Does anyone know why?

Here's the log:

You are not binding to localhost so you are subject to bootstrap checks:

@cosloli

bound or publishing to a non-loopback address, enforcing bootstrap checks

However one of the bootstrap checks is failing:

@cosloli

the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured

To resolve this, configure at least one of the settings given, or disable the bootstrap checks by setting discovery.type: single-node.

thanks a lot! I'll try it now.
