9 mysqlhotcopy arguments
10
12 mysqlhotcopy is a Perl script that was originally written and
13 contributed by Tim Bunce. It uses FLUSH TABLES, LOCK TABLES, and cp or
14 scp to make a database backup. It is a fast way to make a backup of the
15 database or single tables, but it can be run only on the same machine
16 where the database directories are located. mysqlhotcopy works only
17 for backing up MyISAM and ARCHIVE tables. It runs on Unix and NetWare.
18 To use mysqlhotcopy, you must have read access to the files for the
20 tables that you are backing up, the SELECT privilege for those tables,
21 the RELOAD privilege (to be able to execute FLUSH TABLES), and the LOCK
22 TABLES privilege (to be able to lock the tables).
23 shell> mysqlhotcopy db_name [/path/to/new_directory]
25 shell> mysqlhotcopy db_name_1 ... db_name_n /path/to/new_directory
27 Back up tables in the given database that match a regular expression:
29 shell> mysqlhotcopy db_name./regex/
31 The regular expression for the table name can be negated by prefixing
33 it with a tilde (“~”):
34 shell> mysqlhotcopy db_name./~regex/
36 mysqlhotcopy supports the following options, which can be specified on
38 the command line or in the [mysqlhotcopy] and [client] groups of an
39 option file. For information about option files, see Section 4.2.3.3,
40 “Using Option Files”.
41 · --help, -?
43 Display a help message and exit.
45 · --addtodest
47 Do not rename target directory (if it exists); merely add files to
49 it.
50 · --allowold
52 Do not abort if a target exists; rename it by adding an _old
54 suffix.
55 · --checkpoint=db_name.tbl_name
57 Insert checkpoint entries into the specified database db_name and
59 table tbl_name.
60 · --chroot=path
62 Base directory of the chroot jail in which mysqld operates. The
64 path value should match that of the --chroot option given to
65 mysqld.
66 · --debug
68 Enable debug output.
70 · --dryrun, -n
72 Report actions without performing them.
74 · --flushlog
76 Flush logs after all tables are locked.
78 · --host=host_name, -h host_name
80 The host name of the local host to use for making a TCP/IP
82 connection to the local server. By default, the connection is made
83 to localhost using a Unix socket file.
84 · --keepold
86 Do not delete previous (renamed) target when done.
88 · --method=command
90 The method for copying files (cp or scp). The default is cp.
92 · --noindices
94 Do not include full index files for MyISAM tables in the backup.
96 This makes the backup smaller and faster. The indexes for reloaded
97 tables can be reconstructed later with myisamchk -rq.
98 · --password=password, -ppassword
100 The password to use when connecting to the server. The password
102 value is not optional for this option, unlike for other MySQL
103 programs.
104 Specifying a password on the command line should be considered
106 insecure. See Section 6.1.2.1, “End-User Guidelines for Password
107 Security”. You can use an option file to avoid giving the password
108 on the command line.
109 · --port=port_num, -P port_num
111 The TCP/IP port number to use when connecting to the local server.
113 · --quiet, -q
115 Be silent except for errors.
117 · --record_log_pos=db_name.tbl_name
119 Record master and slave status in the specified database db_name
121 and table tbl_name.
122 · --regexp=expr
124 Copy all databases with names that match the given regular
126 expression.
127 · --resetmaster
129 Reset the binary log after locking all the tables.
131 · --resetslave
133 Reset the master.info file after locking all the tables.
135 · --socket=path, -S path
137 The Unix socket file to use for connections to localhost.
139 · --suffix=str
141 The suffix to use for names of copied databases.
143 · --tmpdir=path
145 The temporary directory. The default is /tmp.
147 · --user=user_name, -u user_name
149 The MySQL user name to use when connecting to the server.
151 Use perldoc for additional mysqlhotcopy documentation, including
153 information about the structure of the tables needed for the
154 --checkpoint and --record_log_pos options:
155 shell> perldoc mysqlhotcopy
