NAME

       tarantoolctl - a utility to control Tarantool instances

SYNOPSIS

       tarantoolctl COMMAND [INSTANCE] [FILE] [URI] [OPTIONS...]

DESCRIPTION

       tarantoolctl may be used to introspect and control the state of Tarantool instances.

       The "INSTANCE" represents the name of an instance file.

COMMANDS

       The following commands are understood:

       start INSTANCE
           Start the Tarantool instance specified on the command line if the instance is not running. This does
           nothing if an instance is running.

       stop INSTANCE
           Stop the Tarantool instance specified on the command line if the instance is running. This does
           nothing if an instance is not running.

       status INSTANCE
           Show status of the Tarantool instance specified on the command line (started/stopped). If pid file
           exists and an alive control socket exists, the return code is 0. Otherwise, the return code is not 0.
           Reports typical problems to stderr (e.g. pid file exists and control socket does not).

       restart INSTANCE
           Stop and start the Tarantool instance specified on the command line if the instance is running. This
           does nothing if an instance is not running.

       logrotate INSTANCE
           Rotate logs of the Tarantool instance specified on the command line if the instance is running. This
           works only if logging-into-file is enabled in the instance file ("box.cfg{log=...}" parameter).
           Pipe/syslog make no effect.

       check INSTANCE
           Check if there are syntax errors in the instance script of the Tarantool instance specified on the
           command line.

       enter INSTANCE
           Enter the interactive console of the Tarantool instance specified on the command line.

       eval INSTANCE FILE
       COMMAND | tarantoolctl eval INSTANCE
           Evaluate a local file on the Tarantool instance specified on the command line if the instance is
           running. This does nothing if an instance is not running.

       connect URI
       COMMAND | tarantoolctl connect URI
           Connect on an admin-console port to the Tarantool instance with the URI specified on the command
           line. This supports both TCP/Unix sockets.

       cat FILE... [--space=space_no...] [--show-system] [--from=from_lsn] [--to=to_lsn] [--replica=replica_id]
           Print into stdout the contents of .snap/.xlog files specified on the command line.

       play URI FILE... [--space=space_no...] [--show-system] [--from=from_lsn] [--to=to_lsn]
       [--replica=replica_id]
           Play the contents of .snap/.xlog files to another Tarantool instance with URI specified on the
           command line.

OPTIONS

       The following options are understood:

       --space=space_no
           Filter the output by space number. May be passed more than once.

       --show-system
           Show/play the contents of system spaces.

       --from=from_lsn
           Show/play operations starting from the given lsn.

       --to=to_lsn
           Show/play operations ending with the given lsn.

       --replica=replica_id
           Filter the output by replica ID. May be passed more than once.

CONFIGURATION

       The file with system-wide defaults for tarantoolctl is installed in "/etc/default/tarantool". This file
       is used when tarantoolctl is invoked by root. When invoked by a local user, tarantoolctl first looks for
       its defaults file in the current directory ("$PWD/.tarantoolctl"), and then in the current user's home
       directory ("$HOME/.config/tarantool/tarantool").  If not found, tarantoolctl falls back to built-in
       defaults:

           default_cfg = {
           pid_file  = "/var/run/tarantool",
           wal_dir   = "/var/lib/tarantool",
           memtx_dir = "/var/lib/tarantool",
           vinyl_dir = "/var/lib/tarantool",
           log       = "/var/log/tarantool",
           username  = "tarantool",
           }
           instance_dir = "/etc/tarantool/instances.enabled"

       Most of these parameters are similar to those in "box.cfg{}":

       pid_file
           Directory for the pid file and control-socket file; tarantoolctl will add "/instance_name" to the
           directory name.

       wal_dir
           Directory for write-ahead *.xlog files; tarantoolctl will add "/instance_name" to the directory name.

       memtx_dir
           Directory for snapshot *.snap files; tarantoolctl will add "/instance_name" to the directory name.

       vinyl_dir
           Directory for vinyl files; tarantoolctl will add "/instance_name" to the directory name.

       log The place where the application log will go; tarantoolctl will add "/instance_name.log" to the name.

       username
           The user that runs the Tarantool instance. This is the operating-system user name rather than the
           Tarantool-client user name. Tarantool will change its effective user to this user after becoming a
           daemon.

       instance_dir
           The directory where all instance files for this host are stored. Put instance files in this
           directory, or create symbolic links.

           As a full-featured example, you can take "example.lua" script that ships with Tarantool and defines
           all configuration options.

EXIT STATUS

       On success, 0 is returned, a non-zero failure code otherwise.
