==== Run as a daemon To run Elasticsearch as a daemon, specify `-d` on the command line, and record the process ID in a file using the `-p` option: [source,sh] -------------------------------------------- ./bin/elasticsearch -d -p pid -------------------------------------------- If you have password-protected the {es} keystore, you will be prompted to enter the keystore's password. See <> for more details. Log messages can be found in the `$ES_HOME/logs/` directory. To shut down Elasticsearch, kill the process ID recorded in the `pid` file: [source,sh] -------------------------------------------- pkill -F pid -------------------------------------------- NOTE: The {es} `.tar.gz` package does not include the `systemd` module. To manage {es} as a service, use the <> or <> package instead.
