The method for starting Elasticsearch varies depending on how you installed it.

Archive packages (.tar.gz)edit

If you installed Elasticsearch with a .tar.gz package, you can start Elasticsearch from the command line.

Running Elasticsearch from the command lineedit

Elasticsearch can be started from the command line as follows:

./bin/elasticsearch

If you have password-protected the Elasticsearch keystore, you will be prompted to enter the keystore’s password. See Secure settings for more details.

By default Elasticsearch prints its logs to the console (stdout) and to the <cluster name>.log file within the logs directory. Elasticsearch logs some information while it is starting up, but once it has finished initializing it will continue to run in the foreground and won’t log anything further until something happens that is worth recording. While Elasticsearch is running you can interact with it through its HTTP interface which is on port 9200 by default. To stop Elasticsearch, press Ctrl-C.

Running as a daemonedit

To run Elasticsearch as a daemon, specify -d on the command line, and record the process ID in a file using the -p option:

./bin/elasticsearch -d -p pid

If you have password-protected the Elasticsearch keystore, you will be prompted to enter the keystore’s password. See Secure settings 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:

pkill -F pid

Archive packages (.zip)edit

If you installed Elasticsearch on Windows with a .zip package, you can start Elasticsearch from the command line. If you want Elasticsearch to start automatically at boot time without any user interaction, install Elasticsearch as a service.

Running Elasticsearch from the command lineedit

Elasticsearch can be started from the command line as follows:

.\bin\elasticsearch.bat

If you have password-protected the Elasticsearch keystore, you will be prompted to enter the keystore’s password. See Secure settings for more details.

By default Elasticsearch prints its logs to the console (STDOUT) and to the <cluster name>.log file within the logs directory. Elasticsearch logs some information while it is starting up, but once it has finished initializing it will continue to run in the foreground and won’t log anything further until something happens that is worth recording. While Elasticsearch is running you can interact with it through its HTTP interface which is on port 9200 by default. To stop Elasticsearch, press Ctrl-C.

Debian packagesedit

Elasticsearch is not started automatically after installation. How to start and stop Elasticsearch depends on whether your system uses SysV init or systemd (used by newer distributions). You can tell which is being used by running this command:

ps -p 1

Running Elasticsearch with SysV initedit

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

sudo update-rc.d elasticsearch defaults 95 10

Elasticsearch can be started and stopped using the service command:

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/.

Running Elasticsearch with systemdedit

To configure Elasticsearch to start automatically when the system boots up, run the following commands:

sudo /bin/systemctl daemon-reload
sudo /bin/systemctl enable elasticsearch.service

Elasticsearch can be started and stopped as follows:

sudo systemctl start elasticsearch.service
sudo systemctl stop elasticsearch.service

These commands provide no feedback as to whether Elasticsearch was started successfully or not. Instead, this information will be written in the log files located in /var/log/elasticsearch/.

If you have password-protected your Elasticsearch keystore, you will need to provide systemd with the keystore password using a local file and systemd environment variables. This local file should be protected while it exists and may be safely deleted once Elasticsearch is up and running.

echo "keystore_password" > /path/to/my_pwd_file.tmp
chmod 600 /path/to/my_pwd_file.tmp
sudo systemctl set-environment ES_KEYSTORE_PASSPHRASE_FILE=/path/to/my_pwd_file.tmp
sudo systemctl start elasticsearch.service

By default the Elasticsearch service doesn’t log information in the systemd journal. To enable journalctl logging, the --quiet option must be removed from the ExecStart command line in the elasticsearch.service file.

When systemd logging is enabled, the logging information are available using the journalctl commands:

To tail the journal:

sudo journalctl -f

To list journal entries for the elasticsearch service:

sudo journalctl --unit elasticsearch

To list journal entries for the elasticsearch service starting from a given time:

sudo journalctl --unit elasticsearch --since  "2016-10-30 18:17:16"

Check man journalctl or https://www.freedesktop.org/software/systemd/man/journalctl.html for more command line options.

Docker imagesedit

If you installed a Docker image, you can start Elasticsearch from the command line. There are different methods depending on whether you’re using development mode or production mode. See Docker Run.

RPM packagesedit

Elasticsearch is not started automatically after installation. How to start and stop Elasticsearch depends on whether your system uses SysV init or systemd (used by newer distributions). You can tell which is being used by running this command:

ps -p 1

Running Elasticsearch with SysV initedit

Use the chkconfig command to configure Elasticsearch to start automatically when the system boots up:

sudo chkconfig --add elasticsearch

Elasticsearch can be started and stopped using the service command:

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/.

Running Elasticsearch with systemdedit

sudo /bin/systemctl daemon-reload
sudo /bin/systemctl enable elasticsearch.service

sudo systemctl start elasticsearch.service
