	English	Russian	Actions
	The directory where all instance files for this host are stored. Put instance files in this directory, or create symbolic links.
	The default instance directory depends on Tarantool's ``WITH_SYSVINIT`` build option: when ON, it is ``/etc/tarantool/instances.enabled``, otherwise (OFF or not set) it is ``/etc/tarantool/instances.available``. The latter case is typical for Tarantool builds for Linux distros with ``systemd``.
	To check the build options, say ``tarantool --version``.
	Log rotation in tarantooctl	Утилита tarantoolctl
	With ``tarantoolctl``, :ref:`log rotation <admin-logs>` is pre-configured to use ``logrotate`` program, which you must have installed.
	File ``/etc/logrotate.d/tarantool`` is part of the standard Tarantool distribution, and you can modify it to change the default behavior. This is what this file is usually like:
	/var/log/tarantool/.log { daily size 512k missingok rotate 10 compress delaycompress create 0640 tarantool adm postrotate /usr/bin/tt logrotate `basename ${1%%.}` endscript }
	If you use a different log rotation program, you can invoke ``tarantoolctl logrotate`` command to request instances to reopen their log files after they were moved by the program of your choice.
	Using tarantooctl on FreeBSD
	To make ``tarantoolctl`` work along with ``init.d`` utilities on FreeBSD, use paths other than those suggested in :ref:`Instance configuration <admin-instance_config>`. Instead of ``/usr/share/tarantool/`` directory, use ``/usr/local/etc/tarantool/`` and create the following subdirectories:
	``default`` for ``tarantoolctl`` defaults (see example below),
	``instances.available`` for all available instance files, and
	``instances.enabled`` for instance files to be auto-started by sysvinit.
	Here is an example of ``tarantoolctl`` defaults on FreeBSD:
	default_cfg = { pid_file = "/var/run/tarantool", -- /var/run/tarantool/${INSTANCE}.pid wal_dir = "/var/db/tarantool", -- /var/db/tarantool/${INSTANCE}/ snap_dir = "/var/db/tarantool", -- /var/db/tarantool/${INSTANCE} vinyl_dir = "/var/db/tarantool", -- /var/db/tarantool/${INSTANCE} logger = "/var/log/tarantool", -- /var/log/tarantool/${INSTANCE}.log username = "admin" } -- instances.available - all available instances -- instances.enabled - instances to autostart by sysvinit instance_dir = "/usr/local/etc/tarantool/instances.available"
	Starting and stopping instances	Запуск экземпляра Tarantool’а.
	While a Lua application is executed by Tarantool, an instance file is executed by ``tarantoolctl`` which is a Tarantool script.
	Here is what ``tarantoolctl`` does when you issue the command:
	$ tarantoolctl start <instance_name>	``tarantoolctl start NAME``
	Read and parse the command line arguments. The last argument, in our case, contains an instance name.
	Read and parse its own configuration file. This file contains ``tarantoolctl`` defaults, like the path to the directory where instances should be searched for.
	When ``tarantool`` is invoked by root, it looks for a configuration file in ``/etc/default/tarantool``. When ``tarantool`` is invoked by a local (non-root) user, it looks for a configuration file first in the current directory (``$PWD/.tarantoolctl``), and then in the current user's home directory (``$HOME/.config/tarantool/tarantool``). If no configuration file is found there, or in the ``/usr/local/etc/default/tarantool`` file, then ``tarantoolctl`` falls back to :ref:`built-in defaults <admin-tt_config_file>`.
	Look up the instance file in the instance directory, for example ``/etc/tarantool/instances.enabled``. To build the instance file path, ``tarantoolctl`` takes the instance name, prepends the instance directory and appends ".lua" extension to the instance file.
	Override :doc:`box.cfg{} </reference/reference_lua/box_cfg>` function to pre-process its parameters and ensure that instance paths are pointing to the paths defined in the ``tarantoolctl`` configuration file. For example, if the configuration file specifies that instance work directory must be in ``/var/tarantool``, then the new implementation of ``box.cfg{}`` ensures that :ref:`work_dir <cfg_basic-work_dir>` parameter in ``box.cfg{}`` is set to ``/var/tarantool/<instance_name>``, regardless of what the path is set to in the instance file itself.
	Create a so-called "instance control file". This is a Unix socket with Lua console attached to it. This file is used later by ``tarantoolctl`` to query the instance state, send commands to the instance and so on.
	Set the TARANTOOLCTL environment variable to 'true'. This allows the user to know that the instance was started by ``tarantoolctl``.	Кроме того, данная команда задает значение переменной окружения TARANTOOLCTL = 'true' (правда), чтобы отметить, что экземпляр был запущен с помощью ``tarantoolctl``.
	Finally, use Lua ``dofile`` command to execute the instance file.
	To check the instance file for syntax errors prior to starting ``my_app`` instance, say:
	$ tarantoolctl check my_app	``tarantoolctl check NAME``
	To stop a running ``my_app`` instance, say:
	$ tarantoolctl stop my_app	``tarantoolctl stop NAME``
