==== Running Elasticsearch with SysV `init`

Use the `update-rc.d` command to configure Elasticsearch to start automatically
when the system boots up:

[source,sh]
--------------------------------------------------
sudo update-rc.d elasticsearch defaults 95 10
--------------------------------------------------

Elasticsearch can be started and stopped using the `service` command:

[source,sh]
--------------------------------------------
sudo -i service elasticsearch start
sudo -i service elasticsearch stop
--------------------------------------------

If Elasticsearch fails to start for any reason, it will print the reason for
failure to STDOUT. Log files can be found in `/var/log/elasticsearch/`.
