Start Snow Owl

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

Archive packages (.tar.gz, .zip)

If you installed Snow Owl with a .tar.gz or zip package, you can start Snow Owl from the command line.

Running Snow Owl from the command line

Snow Owl can be started from the command line as follows:

./bin/startup

By default, Snow Owl runs in the foreground, prints some of its logs to the standard output (stdout), and can be stopped by pressing Ctrl-C.

Running as a daemon

To run Snow Owl as a daemon, use the following command:

nohup ./bin/startup > /dev/null &

Log messages can be found in the $SO_HOME/serviceability/logs/ directory.

The startup scripts provided in the RPM and Debian packages take care of starting and stopping the Snow Owl process for you.

RPM packages

Snow Owl is not started automatically after installation. How to start and stop Snow Owl 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 Snow Owl with SysV init

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

sudo chkconfig --add snowowl

Snow Owl can be started and stopped using the service command:

sudo -i service snowowl start
sudo -i service snowowl stop

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

Running Snow Owl with systemd

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

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

Snow Owl can be started and stopped as follows:

sudo systemctl start snowowl.service
sudo systemctl stop snowowl.service

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