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.
