neo4j 3.2.2-1 constant restart just after Failed to find a usable hardware address

I am trying to get neo4j to run on a minimal install of Centos 7.2, neo4j installed through yum.

However it seems to start booting up, but fails, shuts down, then restarts in a continuous loop:

...
2017-07-18 03:06:35.335+0000 INFO [o.n.k.i.f.GraphDatabaseFacadeFactory] Shutdown started

ifconfig gives me:

I've tried setting dbms.connectors.default_listen_address to 0.0.0.0, the static ip, and commenting it out.

I feel like I might be missing a dependency or something that netty uses to get the MAC address, but the netty site claims no dependencies are required.

The last bit of info is that this is an lxc container, but I swear I have had a version of neo4j running in an lxc in the past.

Additionally this is being flagged as a warning, but it seems to be stopping the bootup.

Any thoughts would be greatly appreciated!

Solution

  • Final solution was to not use neo4j-admin and set the password using the web api.

    This link shows a good example using curl: http://430.io/change-neo4j-default-password-in-command-line/

    curl -H "Content-Type: application/json" -X POST -d '{"password":"NEW PASSWORD"}' -u neo4j:neo4j http://localhost:7474/user/neo4j/password
