Curator running problem

Elastic Stack Elasticsearch

Hi all,

I have installed curator via RPM package on CentOS 6.7. I tried to delete some indices on elastic search.
But when I tried to run curator, it gives error as below.

Please let me know if you have any ideas, thanks so much.

Elasticsearch version is 5.2.2
Curator version is 5.1.1.

Just want to add something that I just found here. I did not have python installed, which python version I need to choose.

Since you installed via the RPM, Python is bundled with that. You don't need a separate Python.

This indicates that the host you specified, 127.31.21.47:9200, is not reachable by Curator, or Elasticsearch is not running on port 9200 at that IP address..

Thanks for your reply. I have checked Elasticsearch via typing curl "127.31.21.47:9200" from the terminal, it runs well.
I also checked the config.yml, like this:
client:
hosts: ["127.31.21.47:9200"]

Why it cannot reachable? Thanks.

By changing the logging: block in your config.yml file to have blacklist: [], and loglevel: DEBUG, you will receive more debug information. I can't answer why curl works, and Curator can't. The error Unable to create client connection to Elasticsearch. is pretty clear, though.

Please run with these settings changed, and include the last 20 or so lines of the log after attempting again.

Here's the information that I got after the change based on your suggestion.

It's quite clear that Curator cannot form a connection, regardless of what curl may reveal. On that subject, what do you see when you run curl http://127.31.21.47:9200/?

@theuntergeek

I found the stupid mistake... I put 127 instead of 172... , now it's working. thanks so much.
By the way, can you take a look at this question about elasticsearch? Here's the link.
