一.mysqldump概述
1>.逻辑备份工具
mysqldump:
客户端命令，通过mysql协议连接至mysql服务器进行备份。因此备份过程中需要MySQL数据库实例必须处于可访问状态。

10>.mysqldump常见选项
-A， --all-databases :
备份所有数据库，含create database
-B , --databases db_name…:
指定备份的数据库，包括create database语句
-E, --events:
备份相关的所有event scheduler
-R, --routines:
备份所有存储过程和自定义函数
--triggers:
备份表相关触发器，默认启用,用--skip-triggers，不备份触发器
--default-character-set=utf8
指定字符集
--master-data[=#]：
此选项须启用二进制日志
：所备份的数据之前加一条记录为CHANGE MASTER TO语句，非注释，不指定#，默认为1(一般用于主从复制使用该备份方式,"--master-data=1")
：记录为注释的CHANGE MASTER TO语句(若不用于主从复制只是单纯备份使用"--master-data=2"即可。)
此选项会自动关闭--lock-tables功能，自动打开-x | --lock-all-tables功能（除非开启--single-transaction）
-F, --flush-logs:
备份前滚动日志，锁定表完成后，执行flush logs命令,生成新的二进制日志文件，配合-A 或 -B 选项时，会导致刷新多次数据库。建议在同一时刻执行转储和日志刷新，可通过和--single-transaction或-x，--master-data 一起使用实现，此时只刷新一次日志
--compact:
去掉注释，适合调试，生产不使用
-d, --no-data:
只备份表结构
-t, --no-create-info:
只备份数据,不备份create table
-n,--no-create-db:
不备份create database，可被-A或-B覆盖
--flush-privileges:
备份mysql或权限刷新相关时需要使用
-f, --force:
忽略SQL错误，继续执行
--hex-blob:
使用十六进制符号转储二进制列，当有包括BINARY， VARBINARY，BLOB，BIT的数据类型的列时使用，避免乱码
-q, --quick:
不缓存查询，直接输出，加快备份速度

mysqldump Ver 10.16 Distrib 10.2.-MariaDB, for Linux (x86_64)
Copyright (c) , , Oracle, MariaDB Corporation Ab and others. Dumping structure and contents of MySQL databases and tables.
Usage: mysqldump [OPTIONS] database [tables]
OR mysqldump [OPTIONS] --databases [OPTIONS] DB1 [DB2 DB3...]
OR mysqldump [OPTIONS] --all-databases [OPTIONS] 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: mysqldump client client-server client-mariadb
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.
The following specify which files/extra groups are read (specified before remaining options):
--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=# Additionally read default groups with # appended as a suffix. -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.
(Defaults to on; use --skip-add-drop-table to disable.)
--add-drop-trigger Add a DROP TRIGGER before each create.
--add-locks Add locks around INSERT statements.
(Defaults to on; use --skip-add-locks to disable.)
--allow-keywords Allow creation of column names that are keywords.
--apply-slave-statements
Adds 'STOP SLAVE' prior to 'CHANGE MASTER' and 'START
SLAVE' to bottom of dump.
--character-sets-dir=name
Directory for character set files.
-i, --comments Write additional information.
(Defaults to on; use --skip-comments to disable.)
--compatible=name Change the dump to be compatible with a given mode. By
default tables are dumped in a format optimized for
MySQL. Legal modes are: ansi, mysql323, mysql40,
postgresql, oracle, mssql, db2, maxdb, no_key_options,
no_table_options, no_field_options. One can use several
modes separated by commas. Note: Requires MySQL server
version 4.1. or higher. This option is ignored with
earlier server versions.
--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.
(Defaults to on; use --skip-create-options to disable.)
-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.
(Defaults to on; use --skip-disable-keys to disable.)
--dump-slave[=#] This causes the binary log position and filename of the
master to be appended to the dumped data output. Setting
the value to , will printit as a CHANGE MASTER command
in the dumped data output; if equal to , 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.
-E, --events Dump events.
-e, --extended-insert
Use multiple-row INSERT syntax that include several
VALUES lists.
(Defaults to on; use --skip-extended-insert to disable.)
--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.
-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.
--gtid Used together with --master-data= or --dump-slave=.When
enabled, the output from those options will set the GTID
position instead of the binlog file and offset; the
file/offset will appear only as a comment. When disabled,
the GTID position will still appear in the output, but
only commented.
-?, --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.
--include-master-host-port
Adds 'MASTER_HOST=<host>, MASTER_PORT=<port>' to 'CHANGE
MASTER TO..' in dump produced with --dump-slave.
--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.
(Defaults to on; use --skip-lock-tables to disable.)
--log-error=name Append warnings and errors to given file.
--log-queries When restoring the dump, the server will, if logging
turned on, log the queries to the general and slow query
log.
(Defaults to on; use --skip-log-queries to disable.)
--master-data[=#] This causes the binary log position and filename to be
appended to the output. If equal to , will print it as a
CHANGE MASTER command; if equal to , that command will
be prefixed with a comment symbol. This option will turn
--lock-all-tables on, unless --single-transaction is
specified too (on servers before MariaDB 5.3 this will
still take a global read lock for 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.
--no-data-med No row information for engines that Manage External Data
(MRG_MyISAM, MRG_ISAM, CONNECT, OQGRAPH, SPIDER, VP,
FEDERATED).
(Defaults to on; use --skip-no-data-med to disable.)
-N, --no-set-names Same as --skip-set-charset.
--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.
(Defaults to on; use --skip-quick to disable.)
-Q, --quote-names Quote table and column names with backticks (`).
(Defaults to on; use --skip-quote-names to disable.)
--replace Use REPLACE INTO instead of INSERT INTO.
-r, --result-file=name
Direct output to a given file. This option should be used
in systems (e.g., DOS, Windows) that use carriage-return
linefeed pairs (\r\n) to separate text lines. This option
ensures that only a single newline is used.
-R, --routines Dump stored routines (functions and procedures).
--set-charset Add 'SET NAMES default_character_set' to the output.
(Defaults to on; use --skip-set-charset to disable.)
--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.
(Defaults to on; use --skip-dump-date to disable.)
--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).
--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-crl=name Certificate revocation list (implies --ssl).
--ssl-crlpath=name Certificate revocation list path (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.
(Defaults to on; use --skip-triggers to disable.)
--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.
(Defaults to on; use --skip-tz-utc to disable.)
-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.
--plugin-dir=name Directory for client-side plugins.
--default-auth=name Default authentication client-side plugin to use. Variables (--variable-name=value)
and boolean options {FALSE|TRUE} Value (after reading options)

11>. 分库备份脚本
核心代码如下:
方案一:
for db in `mysql -e 'show databases' |grep -Ev '^(Database|information_schema|performance_schema)$'`;do mysqldump -B $db|gzip > $db`date +%F`.sql.gz;done
方案二:
mysql -e 'show databases' |grep -Ev '^(Database|information_schema|performance_schema)$'|sed -r 's/(.*)/mysqldump -B \1 |gzip > \/data\/\1.sql.gz/' |bash
三.生产环境实战备份策略
1>.MyISAM备份选项
MyISAM支持温备；不支持热备，所以必须先锁定要备份的库，而后启动备份操作
锁定方法如下：
-x,--lock-all-tables：(强烈推荐使用)
加全局读锁，锁定所有库的所有表，同时加--single-transaction或--lock-tables选项会关闭此选项功能
注意：数据量大时，可能会导致长时间无法并发访问数据库
-l,--lock-tables：
对于需要备份的每个数据库，在启动备份之前分别锁定其所有表，默认为on,--skip-lock-tables选项可禁用,对备份MyISAM的多个库,可能会造成数据不一致
注：以上选项对InnoDB表一样生效，实现温备，但不推荐使用
2>.InnoDB备份选项
InnoDB支持热备，可用温备但不建议用
--single-transaction:(强烈推荐使用)
此选项Innodb中推荐使用，不适用MyISAM，此选项会开始备份前，先执行START TRANSACTION指令开启事务
此选项通过在单个事务中转储所有表来创建一致的快照。 仅适用于存储在支持多版本控制的存储引擎中的表（目前只有InnoDB可以）; 转储不保证与其他存储引擎保持一致。 在进行单事务转储时，要确保有效的转储文件（正确的表内容和二进制日志位置），没有其他连接应该使用以下语句：ALTER TABLE，DROP TABLE，RENAME TABLE，TRUNCATE TABLE
此选项和--lock-tables（此选项隐含提交挂起的事务）选项是相互排斥
备份大型表时，建议将--single-transaction选项和--quick结合一起使用
3>.InnoDB建议备份策略
mysqldump –uroot –A –F –E –R --single-transaction --master-data= --flush-privileges --triggers --default-character-set=utf8mb4 --hex-blob >$BACKUP/fullbak_$BACKUP_TIME.sql
4>.MyISAM建议备份策略
mysqldump –uroot –A –F –E –R –x --master-data= --flush-privileges --triggers --default-character-set=utf8mb4 --hex-blob >$BACKUP/fullbak_$BACKUP_TIME.sql
