Although this Library is a good source of information on using Passenger, you do not have to consult this Library for everything. Passenger is self-documenting: every Passenger command supports the
--help option, which will provide you with basic information about the command, its behavior and its syntax.
Here is an example of
$ cd /path-to-your-app $ bundle exec passenger --help Phusion Passenger Standalone, the easiest way to run web apps. Available commands: passenger start Start Phusion Passenger Standalone. passenger stop Stop a Phusion Passenger instance. passenger status Show the status of a running Phusion Passenger instance. Run 'passenger <COMMAND> --help' for more information about each command.
Many Passenger commands support subcommands. These subcommands, too, support
--help. The above output already suggested that you can run
passenger start --help:
$ cd /path-to-your-app $ bundle exec passenger start --help Usage: passenger start [DIRECTORY] [OPTIONS] Starts Passenger Standalone and serve one or more web applications. Server options: -a, --address HOST Bind to the given address. Default: 0.0.0.0 -p, --port NUMBER Use the given port number. Default: 3000 ...
