一.mysqldump概述mysql
1>.邏輯備份工具sql
mysqldump: 客戶端命令，經過mysql協議鏈接至mysql服務器進行備份。所以備份過程當中須要MySQL數據庫實例必須處於可訪問狀態。 博主推薦閱讀:https://dev.mysql.com/doc/refman/5.7/en/mysqldump.html mydumper: 博主推薦閱讀:https://launchpad.net/mydumper/ phpMyAdmin: 一個基於PHP語言開發的Web版本的數據庫管理工具，常見的備份操做都可以再Web點點鼠標就能夠輕鬆完成。該服務須要手動安裝。 博主推薦閱讀:https://www.phpmyadmin.net/
2>.Schema數據庫
Schema存放着數據的各類定義，DDL語言("CREATE DATABASE","CREATE TABLE","CREATE VIEW"等)包括經過INSERT語句導出各類數據。
Schema和數據存儲在一塊兒、巨大的SQL語句、單個巨大的備份文件
3>.mysqldump工具centos
客戶端命令，經過mysql協議鏈接至mysql服務器進行備份。 博主推薦閱讀: https://dev.mysql.com/doc/refman/5.7/en/mysqldump.html
二.mysqldump經常使用選項案例緩存
1>.備份指定的數據庫(僅備份該數據庫下全部的表，但不包括create database語句，生產環境不推薦使用)bash

[root@node105.yinzhengjie.org.cn ~]# mysqldump --help mysqldump Ver 10.16 Distrib 10.2.19-MariaDB, for Linux (x86_64) Copyright (c) 2000, 2018, 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 4.1.0 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.

三.生產環境實戰備份策略
1>.MyISAM備份選項
MyISAM支持溫備；不支持熱備，因此必須先鎖定要備份的庫，然後啓動備份操做 鎖定方法以下： -x,--lock-all-tables：(強烈推薦使用)
加全局讀鎖，鎖定全部庫的全部表，同時加--single-transaction或--lock-tables選項會關閉此選項功能 注意：數據量大時，可能會致使長時間沒法併發訪問數據庫 -l,--lock-tables：
對於須要備份的每一個數據庫，在啓動備份以前分別鎖定其全部表，默認爲on,--skip-lock-tables選項可禁用,對備份MyISAM的多個庫,可能會形成數據不一致 注：以上選項對InnoDB表同樣生效，實現溫備，但不推薦使用
2>.InnoDB備份選項
InnoDB支持熱備，可用溫備但不建議用 --single-transaction:(強烈推薦使用) 此選項Innodb中推薦使用，不適用MyISAM，此選項會開始備份前，先執行START TRANSACTION指令開啓事務 此選項經過在單個事務中轉儲全部表來建立一致的快照。 僅適用於存儲在支持多版本控制的存儲引擎中的表（目前只有InnoDB能夠）; 轉儲不保證與其餘存儲引擎保持一致。 在進行單事務轉儲時，要確保有效的轉儲文件（正確的表內容和二進制日誌位置），沒有其餘鏈接應該使用如下語句：ALTER TABLE，DROP TABLE，RENAME TABLE，TRUNCATE TABLE 此選項和--lock-tables（此選項隱含提交掛起的事務）選項是相互排斥 備份大型表時，建議將--single-transaction選項和--quick結合一塊兒使用
3>.InnoDB建議備份策略
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建議備份策略
mysqldump –uroot –A –F –E –R –x --master-data=1 --flush-privileges --triggers --default-character-set=utf8mb4 --hex-blob >$BACKUP/fullbak_$BACKUP_TIME.sql
