I installed CrateDB on an Ubuntu server 18.04 across the LAN. But I am not able to access the Admin-UI and I get the following message:

Firefox can’t establish a connection to the server at 192.168.1.102:4200.

How can i solve this problem?

CrateDB is running on the server and this is the status:

sudo systemctl status crate.service

crate.service - CrateDB Server

  • What does your 'network.*' configuration look like? – Caramiriel Jun 30 '18 at 17:58
  • Do you mean network configuration for CrateDB?. Where can i find it?. Otherwise, i have no problem with firewall and accessing all other services like apache, MySQL etc over the LAN. – R.Alamsha Jun 30 '18 at 18:06

per default cratedb binds itself to local which means that you can't access it from the outside.

you need to set network.host to something like _site_.

https://crate.io/docs/crate/reference/en/latest/config/node.html#hosts

you need to make sure all the bootstrap checks pass: https://crate.io/docs/crate/guide/en/latest/admin/bootstrap-checks.html

Solution 1

And in addition to what @Johannes Moser has replied, that first you need to add your machine's IP in crate.yml file, against network.host.

Then optionally you can specify psql.port, which defaults to 5432, and then you can access Crate from outside like:

l.oc.al.ip/PSQL_PORT

Solution 2

Use nGROK

ngrok exposes local servers behind NATs and firewalls to the public internet over secure tunnels.
