Unable to set up Elasticsearch for Wagtail

I used the following guide so far:

http://docs.wagtail.io/en/v1.9/advanced_topics/performance.html

I added: 

WAGTAILSEARCH_BACKENDS = {
    'default': {
        'BACKEND': 'wagtail.wagtailsearch.backends.elasticsearch',
        'INDEX': '{{ project_name }}',
    },
}

to my base.py. When I run $ ./manage.py update_index, I get the following output:

Updating backend: default
default: Rebuilding index {{ project_name }}
Traceback (most recent call last):

Thanks in advance.

EDIT UPDATE:

It looks like my Linode might not have enough RAM. I get the following error when trying to run ES with ./bin/elasticsearch after global install:

OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x0000000085330000, 2060255232, 0) failed; error='Cannot allocate memory' (errno=12)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 2060255232 bytes for committing reserved memory.
# An error report file with more information is saved as:

Thanks.

For people still having issues with this, make sure your Elasticsearch version and elasticsearch-py version are the same. Both elasticsearch and the py versions need to be installed. That fixed it for me.

sorry I don't have enough reputation to comment directly under your question, I hope this will help you to get things sorted out:

  • install elasticsearch locally, run it, and then check if it's running (should be on port 9200) using a simple curl http://localhost:9200. If you get a JSON response, it's running 🎉

OR

  • setup a bonsai (http://bonsai.io) instance in order to have a hosted elasticsearch server running, and just copy-paste the bonsai's server URL into your config, but it can need a bit more settings (SSL etc), and is more limited in term of elasticsearch version

Bonus: if you are a macOS user, installing/running Elastic Search is as easy as brew install elasticsearch (maybe set a specific version though), and then elasticsearch if you don't mind about having it running in the foreground.
