Elasticsearch 6.4.0 won't start on RHEL7

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
