I installed per the instructions at https://opensearch.org/docs/latest/install-and-configure/install-opensearch/..., but it fails to start:
$ sudo systemctl start opensearch Job for opensearch.service failed because the control process exited with error code. See "systemctl status opensearch.service" and "journalctl -xeu opensearch.service" for details.
$ systemctl status opensearch.service × opensearch.service - OpenSearch Loaded: loaded (/lib/systemd/system/opensearch.service; enabled; preset: enabled) Active: failed (Result: exit-code) since Tue 2023-12-19 15:24:58 UTC; 7min ago Docs: https://opensearch.org/ Process: 43719 ExecStart=/usr/share/opensearch/bin/systemd-entrypoint -p ${PID_DIR}/opensearch.pid --quiet (code=exited, status=1/FAILURE) Main PID: 43719 (code=exited, status=1/FAILURE) CPU: 2.001s
This is on opensearch.spi-tools.eqiad1.wikimedia.cloud https://horizon.wikimedia.org/project/instances/c282d273-6007-4320-9df2-69cd949a1a37/. It’s a brand new debian bookworm instance I just spun up for this. The only configuration I’ve done was to increase vm.max_map_count per their recommendation:
$ cat /proc/sys/vm/max_map_count 262144
Any ideas?

I want to install elasticsearch on a VPS instance. I’m guessing this involves puppet, but can’t figure out the details. The instructions at https://wikitech.wikimedia.org/wiki/Help:Puppet don’t match what I’m actually seeing in Horizon. I go to the Puppet Configuration tab for my instance and there’s no project/common/all sub-pages as described under Apply a puppet role to or change hiera config of an individual instance.
Hi Roy,
Elasticsearch is licensed under a non-free license, so I would encourage you to use OpenSearch instead, as the Cloud Services terms of use [1] require that only OSI-compliant software is installed in Cloud VPS instances.
The screenshots included in https://wikitech.wikimedia.org/wiki/Help:Puppet are a bit old, the interface is now slightly different. We will update that page, but in the meantime my recommendation is to ignore Puppet and install OpenSearch by logging into your Cloud VPS instance and following the upstream instructions at https://opensearch.org/docs/latest/install-and-configure/install-opensearch/...
Let us know if that works or if you run into further issues!
Thanks, Francesco
