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。 博主推荐阅读:https://dev.mysql.com/doc/refman/5.7/en/mysqldump.html mydumper: 博主推荐阅读:https://launchpad.net/mydumper/ phpMyAdmin: 一个基于PHP语言开发的Web版本的数据库管理工具，常见的备份操作均可以再Web点点鼠标就可以轻松完成。该服务需要手动安装。 博主推荐阅读:https://www.phpmyadmin.net/
2>.Schema
Schema存放着数据的各种定义，DDL语言("CREATE DATABASE","CREATE TABLE","CREATE VIEW"等)包括通过INSERT语句导出各种数据。
Schema和数据存储在一起、巨大的SQL语句、单个巨大的备份文件

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 1：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") 2：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

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 4.1.0 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 1, will printit as a CHANGE MASTER command in the dumped data output; 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. -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=1 or --dump-slave=1.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 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 (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.

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=1 --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=1 --flush-privileges --triggers --default-character-set=utf8mb4 --hex-blob >$BACKUP/fullbak_$BACKUP_TIME.sql
