tarantoolctl - Man Page
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 not0
. 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.
