NAME

6       tarantoolctl - a utility to control Tarantool instances
7

SYNOPSIS

9       tarantoolctl COMMAND [INSTANCE] [FILE] [URI] [OPTIONS...]
10

DESCRIPTION

12       tarantoolctl may be used to introspect and control the state of
13       Tarantool instances.
14
15       The "INSTANCE" represents the name of an instance file.
16

COMMANDS

18       The following commands are understood:
19
20       start INSTANCE
21           Start the Tarantool instance specified on the command line if the
22           instance is not running. This does nothing if an instance is
23           running.
24
25       stop INSTANCE
26           Stop the Tarantool instance specified on the command line if the
27           instance is running. This does nothing if an instance is not
28           running.
29
30       status INSTANCE
31           Show status of the Tarantool instance specified on the command line
32           (started/stopped). If pid file exists and an alive control socket
33           exists, the return code is 0. Otherwise, the return code is not 0.
34           Reports typical problems to stderr (e.g. pid file exists and
35           control socket does not).
36
37       restart INSTANCE
38           Stop and start the Tarantool instance specified on the command line
39           if the instance is running. This does nothing if an instance is not
40           running.
41
42       logrotate INSTANCE
43           Rotate logs of the Tarantool instance specified on the command line
44           if the instance is running. This works only if logging-into-file is
45           enabled in the instance file ("box.cfg{log=...}" parameter).
46           Pipe/syslog make no effect.
47
48       check INSTANCE
49           Check if there are syntax errors in the instance script of the
50           Tarantool instance specified on the command line.
51
52       enter INSTANCE
53           Enter the interactive console of the Tarantool instance specified
54           on the command line.
55
56       eval INSTANCE FILE
57       COMMAND | tarantoolctl eval INSTANCE
58           Evaluate a local file on the Tarantool instance specified on the
59           command line if the instance is running. This does nothing if an
60           instance is not running.
61
62       connect URI
63       COMMAND | tarantoolctl connect URI
64           Connect on an admin-console port to the Tarantool instance with the
65           URI specified on the command line. This supports both TCP/Unix
66           sockets.
67
68       cat FILE... [--space=space_no...] [--show-system] [--from=from_lsn]
69       [--to=to_lsn] [--replica=replica_id]
70           Print into stdout the contents of .snap/.xlog files specified on
71           the command line.
72
73       play URI FILE... [--space=space_no...] [--show-system]
74       [--from=from_lsn] [--to=to_lsn] [--replica=replica_id]
75           Play the contents of .snap/.xlog files to another Tarantool
76           instance with URI specified on the command line.
77

OPTIONS

79       The following options are understood:
80
81       --space=space_no
82           Filter the output by space number. May be passed more than once.
83
84       --show-system
85           Show/play the contents of system spaces.
86
87       --from=from_lsn
88           Show/play operations starting from the given lsn.
89
90       --to=to_lsn
91           Show/play operations ending with the given lsn.
92
93       --replica=replica_id
94           Filter the output by replica ID. May be passed more than once.
95

CONFIGURATION

97       The file with system-wide defaults for tarantoolctl is installed in
98       "/etc/default/tarantool". This file is used when tarantoolctl is
99       invoked by root. When invoked by a local user, tarantoolctl first looks
100       for its defaults file in the current directory ("$PWD/.tarantoolctl"),
101       and then in the current user's home directory
102       ("$HOME/.config/tarantool/tarantool").  If not found, tarantoolctl
103       falls back to built-in defaults:
104
105           default_cfg = {
106           pid_file  = "/var/run/tarantool",
107           wal_dir   = "/var/lib/tarantool",
108           memtx_dir = "/var/lib/tarantool",
109           vinyl_dir = "/var/lib/tarantool",
110           log       = "/var/log/tarantool",
111           username  = "tarantool",
112           }
113           instance_dir = "/etc/tarantool/instances.enabled"
114
115       Most of these parameters are similar to those in "box.cfg{}":
116
117       pid_file
118           Directory for the pid file and control-socket file; tarantoolctl
119           will add "/instance_name" to the directory name.
120
121       wal_dir
122           Directory for write-ahead *.xlog files; tarantoolctl will add
123           "/instance_name" to the directory name.
124
125       memtx_dir
126           Directory for snapshot *.snap files; tarantoolctl will add
127           "/instance_name" to the directory name.
128
129       vinyl_dir
130           Directory for vinyl files; tarantoolctl will add "/instance_name"
131           to the directory name.
132
133       log The place where the application log will go; tarantoolctl will add
134           "/instance_name.log" to the name.
135
136       username
137           The user that runs the Tarantool instance. This is the operating-
138           system user name rather than the Tarantool-client user name.
139           Tarantool will change its effective user to this user after
140           becoming a daemon.
141
142       instance_dir
143           The directory where all instance files for this host are stored.
144           Put instance files in this directory, or create symbolic links.
145
146           As a full-featured example, you can take "example.lua" script that
147           ships with Tarantool and defines all configuration options.
148

EXIT STATUS

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