When I first tried to deploy Elasticsearch, I got stuck at a bug
. So, I restored from backup to get a clean system again. I tried again after a few days and it worked then.
You should have 8GB of RAM. When I had 4GB, the Out Of Memory Manager kept killing the elasticsearch process. Also, if sidekiq complains about Faraday connection lost, it's elasticsearch down. You can check what the problem is with "systemctl status elasticsearch". Test with "live/bin/tootctl search deploy".
Follow the documentation on joimastodon.org
to get elasticsearch running.
There's no documentation on how to use a username & password in Mastodon for accessing Elasticsearch, but I managed to configure some basic security.
First, find the Elasticsearch configuration file:
find / -name elasticsearch.yml
Then edit the file and add the following lines:
Generate the passwords following the guide at Set up minimal security for Elasticsearch
(replace the version number in the link with your Elasticsearch version).
Then configure live/.env.production with:
Restart the service with sudo systemctl restart elasticsearch
and then test the setup with live/bin/tootctl search deploy --only tags
Edit the elasticsearch.yml
file again and add this entry:
If you are running a cluster rather than just a local installation, refer to Secure the Elastic Stack
. I'm not running a cluster, so I have no experience to share about this.
