Hi Elastic team,

I am trying to install and run Elasticsearch 6.4.0 on RHEL 7 with JAVA:  
java version "1.8.0\_181"  
Java(TM) SE Runtime Environment (build 1.8.0\_181-b13)  
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)

However, upon running `rpm --install elasticsearch-6.4.0.rpm`, I get this error:

```
Exception in thread "main" java.nio.file.FileAlreadyExistsException: /etc/elasticsearch/elasticsearch.keystore.tmp

```

It seems that there is no elasticsearch.keystore under /etc/elasticsearch. I only manage to see elasticsearch.keystore.tmp. I tried to find elasticsearch-keystore under /bin as suggested in some related articles but couldn't also find it.

How/where can I generate this elasticsearch.keystore?

Thanks in advance.

Hi @Jason_Almonte ,

I would recommend to proceed as follows:

- Create a copy of `/etc/elasticsearch/elasticsearch.keystore.tmp`
- Delete `/etc/elasticsearch/elasticsearch.keystore.tmp`

Then:

1. Try to start Elasticsearch. If it starts: Done
2. If Elasticsearch does not start: (i) locate `elasticsearch-keystore` (the location depends on your distribution: this will be in your Elasticsearch installation directory; for me, that is `/usr/share/elasticsearch`); (ii) create the keystore
