This program can be used to CHECK (-c, -m, -C), REPAIR (-r), ANALYZE (-a),
or OPTIMIZE (-o) tables. Some of the options (like -e or -q) can be
used at the same time. Not all options are supported by all storage engines.
Please consult the MySQL manual for latest information about the
above. The options -c, -r, -a, and -o are exclusive to each other, which
means that the last option will be used, if several was specified.
The option -c will be used by default, if none was specified. You
can change the default behavior by making a symbolic link, or
copying this file somewhere with another name, the alternatives are:
mysqlrepair: The default option will be -r
mysqlanalyze: The default option will be -a
mysqloptimize: The default option will be -o
Usage: mysqlcheck [OPTIONS] database [tables]
OR mysqlcheck [OPTIONS] --databases DB1 [DB2 DB3...]
OR mysqlcheck [OPTIONS] --all-databases
Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf ~/.my.cnf
The following groups are read: mysqlcheck client
The following options may be given as the first argument:
--print-defaults Print the program argument list and exit.
--no-defaults Don't read default options from any option file,
except for login file.
--defaults-file=# Only read default options from the given file #.
--defaults-extra-file=# Read this file after the global files are read.
--defaults-group-suffix=#
Also read groups with concat(group, suffix)
--login-path=# Read this path from the login file.
-A, --all-databases Check all the databases. This is the same as --databases
with all databases selected.
-a, --analyze Analyze given tables.
-1, --all-in-1 Instead of issuing one query for each table, use one
query per database, naming all tables in the database in
a comma-separated list.
--auto-repair If a checked table is corrupted, automatically fix it.
Repairing will be done after all tables have been
checked, if corrupted ones were found.
--bind-address=name IP address to bind to.
--character-sets-dir=name
Directory for character set files.
-c, --check Check table for errors.
-C, --check-only-changed
Check only tables that have changed since last check or
haven't been closed properly.
-g, --check-upgrade Check tables for version-dependent changes. May be used
with --auto-repair to correct tables requiring
version-dependent updates.
--compress Use compression in server/client protocol.
-B, --databases Check several databases. Note the difference in usage; in
this case no tables are given. All name arguments are
regarded as database names.
-#, --debug[=#] This is a non-debug version. Catch this and exit.
--debug-check This is a non-debug version. Catch this and exit.
--debug-info This is a non-debug version. Catch this and exit.
--default-character-set=name
Set the default character set.
--default-auth=name Default authentication client-side plugin to use.
--enable-cleartext-plugin
Enable/disable the clear text authentication plugin.
-F, --fast Check only tables that haven't been closed properly.
--fix-db-names Fix database names.
--fix-table-names Fix table names.
-f, --force Continue even if we get an SQL error.
-e, --extended If you are using this option with CHECK TABLE, it will
ensure that the table is 100 percent consistent, but will
take a long time. If you are using this option with
REPAIR TABLE, it will force using old slow repair with
keycache method, instead of much faster repair by
sorting.
-?, --help Display this help message and exit.
-h, --host=name Connect to host.
-m, --medium-check Faster than extended-check, but only finds 99.99 percent
of all errors. Should be good enough for most cases.
--write-binlog Log ANALYZE, OPTIMIZE and REPAIR TABLE commands. Use
--skip-write-binlog when commands should not be sent to
replication slaves.
(Defaults to on; use --skip-write-binlog to disable.)
--secure-auth Refuse client connecting to server if it uses old
(pre-4.1.1) protocol. Deprecated. Always TRUE
-o, --optimize Optimize table.
-p, --password[=name]
Password to use when connecting to server. If password is
not given, it's solicited on the tty.
--plugin-dir=name Directory for client-side plugins.
-P, --port=# Port number to use for connection or 0 for default to, in
order of preference, my.cnf, $MYSQL_TCP_PORT,
/etc/services, built-in default (3306).
--protocol=name The protocol to use for connection (tcp, socket, pipe,
memory).
-q, --quick If you are using this option with CHECK TABLE, it
prevents the check from scanning the rows to check for
wrong links. This is the fastest check. If you are using
this option with REPAIR TABLE, it will try to repair only
the index tree. This is the fastest repair method for a
table.
-r, --repair Can fix almost anything except unique keys that aren't
unique.
-s, --silent Print only error messages.
--skip-database=name
Don't process the database specified as argument
-S, --socket=name The socket file to use for connection.
--ssl-mode=name SSL connection mode.
--ssl Deprecated. Use --ssl-mode instead.
(Defaults to on; use --skip-ssl to disable.)
--ssl-verify-server-cert
Deprecated. Use --ssl-mode=VERIFY_IDENTITY instead.
--ssl-ca=name CA file in PEM format.
--ssl-capath=name CA directory.
--ssl-cert=name X509 cert in PEM format.
--ssl-cipher=name SSL cipher to use.
--ssl-key=name X509 key in PEM format.
--ssl-crl=name Certificate revocation list.
--ssl-crlpath=name Certificate revocation list path.
--tls-version=name TLS version to use, permitted values are: TLSv1, TLSv1.1
--tables Overrides option --databases (-B).
--use-frm When used with REPAIR, get table structure from .frm
file, so the table can be repaired even if .MYI header is
corrupted.
-u, --user=name User for login if not current user.
-v, --verbose Print info about the various stages.
-V, --version Output version information and exit.
