mysqldump 参数：

常用参数

--databases

--all-databases

--single-transaction

--master-data=2

--quick

--events

--routines

--ignore-table

-d

-R

-A, --all-databases    Dump all the databases. This will be same as --databases with all databases selected.
-Y, --all-tablespaces     Dump all the tablespaces.
-y, --no-tablespaces     Do not dump any tablespace information.
--add-drop-database    Add a DROP DATABASE before each create.
--add-drop-table          Add a DROP TABLE before each create.
--add-locks                 Add locks around INSERT statements.
--allow-keywords        Allow creation of column names that are keywords.
--character-sets-dir=name Directory for character set files.
-i, --comments Write additional information.
--compatible=name Change the dump to be compatible with a given mode. 
--compact Give less verbose output (useful for debugging). Disables
structure comments and header/footer constructs. Enables
options --skip-add-drop-table --skip-add-locks
--skip-comments --skip-disable-keys --skip-set-charset.
-c, --complete-insert
Use complete insert statements.
-C, --compress Use compression in server/client protocol.
-a, --create-options
Include all MySQL specific create options.
-B, --databases Dump several databases. Note the difference in usage; in
this case no tables are given. All name arguments are
regarded as database names. 'USE db_name;' will be
included in the output.
-#, --debug[=#] This is a non-debug version. Catch this and exit.
--debug-check Check memory and open file usage at exit.
--debug-info Print some debug info at exit.
--default-character-set=name
Set the default character set.
--delayed-insert Insert rows with INSERT DELAYED.
--delete-master-logs
Delete logs on master after backup. This automatically
enables --master-data.
-K, --disable-keys '/*!40000 ALTER TABLE tb_name DISABLE KEYS */; and
'/*!40000 ALTER TABLE tb_name ENABLE KEYS */; will be put
in the output.
-E, --events Dump events.
-e, --extended-insert
Use multiple-row INSERT syntax that include several
VALUES lists.
--fields-terminated-by=name
Fields in the output file are terminated by the given
string.
--fields-enclosed-by=name
Fields in the output file are enclosed by the given
character.
--fields-optionally-enclosed-by=name
Fields in the output file are optionally enclosed by the
given character.
--fields-escaped-by=name
Fields in the output file are escaped by the given
character.
--first-slave Deprecated, renamed to --lock-all-tables.
-F, --flush-logs Flush logs file in server before starting dump. Note that
if you dump many databases at once (using the option
--databases= or --all-databases), the logs will be
flushed for each database dumped. The exception is when
using --lock-all-tables or --master-data: in this case
the logs will be flushed only once, corresponding to the
moment all tables are locked. So if you want your dump
and the log flush to happen at the same exact moment you
should use --lock-all-tables or --master-data with
--flush-logs.
--flush-privileges Emit a FLUSH PRIVILEGES statement after dumping the mysql
database. This option should be used any time the dump
contains the mysql database and any other database that
depends on the data in the mysql database for proper
restore.
-f, --force Continue even if we get an SQL error.
-?, --help Display this help message and exit.
--hex-blob Dump binary strings (BINARY, VARBINARY, BLOB) in
hexadecimal format.
-h, --host=name Connect to host.
--ignore-table=name Do not dump the specified table. To specify more than one
table to ignore, use the directive multiple times, once
for each table. Each table must be specified with both
database and table names, e.g.,
--ignore-table=database.table.
--insert-ignore Insert rows with INSERT IGNORE.
--lines-terminated-by=name
Lines in the output file are terminated by the given
string.
-x, --lock-all-tables
Locks all tables across all databases. This is achieved
by taking a global read lock for the duration of the
whole dump. Automatically turns --single-transaction and
--lock-tables off.
-l, --lock-tables Lock all tables for read.
--log-error=name Append warnings and errors to given file.
--master-data[=#] This causes the binary log position and filename to be
appended to the output. If equal to 1, will print it as a
CHANGE MASTER command; if equal to 2, that command will
be prefixed with a comment symbol. This option will turn
--lock-all-tables on, unless --single-transaction is
specified too (in which case a global read lock is only
taken a short time at the beginning of the dump; don't
forget to read about --single-transaction below). In all
cases, any action on logs will happen at the exact moment
of the dump. Option automatically turns --lock-tables
off.
--max_allowed_packet=#
The maximum packet length to send to or receive from
server.
--net_buffer_length=#
The buffer size for TCP/IP and socket communication.
--no-autocommit Wrap tables with autocommit/commit statements.
-n, --no-create-db Suppress the CREATE DATABASE ... IF EXISTS statement that
normally is output for each dumped database if
--all-databases or --databases is given.
-t, --no-create-info
Don't write table creation info.
-d, --no-data No row information.
-N, --no-set-names Suppress the SET NAMES statement
--opt Same as --add-drop-table, --add-locks, --create-options,
--quick, --extended-insert, --lock-tables, --set-charset,
and --disable-keys. Enabled by default, disable with
--skip-opt.
--order-by-primary Sorts each table's rows by primary key, or first unique
key, if such a key exists. Useful when dumping a MyISAM
table to be loaded into an InnoDB table, but will make
the dump itself take considerably longer.
-p, --password[=name]
Password to use when connecting to server. If password is
not given it's solicited on the tty.
-P, --port=# Port number to use for connection.
--protocol=name The protocol to use for connection (tcp, socket, pipe,
memory).
-q, --quick Don't buffer query, dump directly to stdout.
-Q, --quote-names Quote table and column names with backticks (`).
--replace Use REPLACE INTO instead of INSERT INTO.
-r, --result-file=name
Direct output to a given file. This option should be used
in MSDOS, because it prevents new line '\n' from being
converted to '\r\n' (carriage return + line feed).
-R, --routines Dump stored routines (functions and procedures).
--set-charset Add 'SET NAMES default_character_set' to the output.
Enabled by default; suppress with --skip-set-charset.
-O, --set-variable=name
Change the value of a variable. Please note that this
option is deprecated; you can set variables directly with
--variable-name=value.
--single-transaction
Creates a consistent snapshot by dumping all tables in a
single transaction. Works ONLY for tables stored in
storage engines which support multiversioning (currently
only InnoDB does); the dump is NOT guaranteed to be
consistent for other storage engines. While a
--single-transaction dump is in process, to ensure a
valid dump file (correct table contents and binary log
position), no other connection should use the following
statements: ALTER TABLE, DROP TABLE, RENAME TABLE,
TRUNCATE TABLE, as consistent snapshot is not isolated
from them. Option automatically turns off --lock-tables.
--dump-date Put a dump date to the end of the output.
--skip-opt Disable --opt. Disables --add-drop-table, --add-locks,
--create-options, --quick, --extended-insert,
--lock-tables, --set-charset, and --disable-keys.
-S, --socket=name The socket file to use for connection.
--ssl Enable SSL for connection (automatically enabled with
other flags).Disable with --skip-ssl.
--ssl-ca=name CA file in PEM format (check OpenSSL docs, implies
--ssl).
--ssl-capath=name CA directory (check OpenSSL docs, implies --ssl).
--ssl-cert=name X509 cert in PEM format (implies --ssl).
--ssl-cipher=name SSL cipher to use (implies --ssl).
--ssl-key=name X509 key in PEM format (implies --ssl).
--ssl-verify-server-cert
Verify server's "Common Name" in its cert against
hostname used when connecting. This option is disabled by
default.
-T, --tab=name Create tab-separated textfile for each table to given
path. (Create .sql and .txt files.) NOTE: This only works
if mysqldump is run on the same machine as the mysqld
server.
--tables Overrides option --databases (-B).
--triggers Dump triggers for each dumped table.
--tz-utc SET TIME_ZONE='+00:00' at top of dump to allow dumping of
TIMESTAMP data when a server has data in different time
zones or data is being moved between servers with
different time zones.
-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.
-w, --where=name Dump only selected records. Quotes are mandatory.
-X, --xml Dump a database as well formed XML.

mysqlcheck 参数：

--print-defaults Print the program argument list and exit.
--no-defaults Don't read default options from any option file.
--defaults-file=# Only read default options from the given file #.
--defaults-extra-file=# Read this file after the global files are read.
-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.
--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 Check memory and open file usage at exit.
--debug-info Print some debug info at exit.
--default-character-set=name
Set the default character set.
-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. Enabled
by default; use --skip-write-binlog when commands should
not be sent to replication slaves.
-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.
-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.
-S, --socket=name The socket file to use for connection.
--ssl Enable SSL for connection (automatically enabled with
other flags).Disable with --skip-ssl.
--ssl-ca=name CA file in PEM format (check OpenSSL docs, implies
--ssl).
--ssl-capath=name CA directory (check OpenSSL docs, implies --ssl).
--ssl-cert=name X509 cert in PEM format (implies --ssl).
--ssl-cipher=name SSL cipher to use (implies --ssl).
--ssl-key=name X509 key in PEM format (implies --ssl).
--ssl-verify-server-cert
Verify server's "Common Name" in its cert against
hostname used when connecting. This option is disabled by
default.
--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.
