I've been trying to start ES for hours and I can't seem to be able to do so.
sudo service elasticsearch status prints out :
elasticsearch.service - Elasticsearch Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since ven. 2019-01-11 12:22:33 CET; 5min ago Docs: http://www.elastic.co Process: 16713 ExecStart=/usr/share/elasticsearch/bin/elasticsearch -Des.pidfile=$PID_DIR/elasticsearch.pid -Des.default.path.home=$ES_HOME -Des.default.path.logs=$LOG_DIR -Des.default.path.data=$DATA_DIR -Des.default.confi Main PID: 16713 (code=exited, status=1/FAILURE) janv. 11 12:22:33 glamuse systemd: Started Elasticsearch. janv. 11 12:22:33 glamuse systemd: elasticsearch.service: Main process exited, code=exited, status=1/FAILURE janv. 11 12:22:33 glamuse systemd: elasticsearch.service: Unit entered failed state. janv. 11 12:22:33 glamuse systemd: elasticsearch.service: Failed with result 'exit-code'.
I've increased the memory and done all the fixes I could find on the internet, but I can't seem to figure out what's going on, there's not even a single log generated today... So I don't even have any trace of where the error could be.
Any idea how can I debug this?
