elasticsearch can't install head plugin

I am planing to install head pluging for elasticsearch.

in both these two official documentation, http://mobz.github.io/elasticsearch-head/ and http://docs.couchbase.com/admin/elastic/install-plugin.html they said to use this: 

bin/plugin -install mobz/elasticsearch-head

I did, but i got the following error:

PS C:\elasticsearch-1.3.9\elasticsearch-1.3.9> bin/plugin -install mobz/elasticsearch-head

as I was trying to diagnosis the error, I found that there might b something wrong in elasticsearch.yml file. I went to that file, and opened it using notpadd++, and it was all commented except the last three-four lines, they were letters not understandable. this is a print screen of them:

could you help please

Solution

  • In that file you shouldn't have those chars. Remove them and start over. Or take a clean instance of ES, take the config file from that and use it.
