Elastic Search Digital Ocean

Question

I tried to install elasticsearch in my droplet on Digital Ocean.

When I execute command to start elasticsearch,

cd /usr/share/elasticsearch/bin
./elasticsearch

I get this error:

Answer 1

The problem occurs when you have installed elasticsearch via a package but are attempting to run via the command line instead of the service.

Try this instead:

sudo service elasticsearch start

Also, try changing #START_DAEMON toSTART_DAEMON (if it's not already uncommented) in /etc/default/elasticsearch and then restart the service.

If you absolutely must run it from the command line then try the archive distribution instead.
