Hi,

I'm getting an error while trying to install X-Pack. I'm running this as root, in the ES\_HOME directory (but it's not the standard location). Elastic is running, along with Kibana on this server, and it has internet access.  
Any suggestions?

[root@flow1 elasticsearch-6.2.4]# bin/elasticsearch-plugin install x-pack

It doesn't look like your machine has direct internet access. The x-pack install process downloads the plugin from our servers.  
If your machine is unable to do that, you should follow the offline install process described here:

- [https://www.elastic.co/guide/en/elasticsearch/reference/6.2/installing-xpack-es.html](https://www.elastic.co/guide/en/elasticsearch/reference/6.2/installing-xpack-es.html)

In particular, follow _step 1_ and the second part of _step 2_.
