主要使用命令为：
$ bin/mysqlbinlog
具体使用方法，直接参数 $ bin/mysqlbinglog --help 输出信息。
我在操作的时候，主要是针对某个 mysql-bin.000006 文件转 SQL 数据！命令为：
[mysql@ryan mysql]# bin/mysqlbinlog --no-defaults -v --base64-output=DECODE-ROWS binlog_data/mysql-bin.000006 > ./my-sql.sql
-----------------------------
遇到的问题：
1. 执行 bin/mysqlbinlog 命令，报错如下：
[mysql@ryan mysql]# bin/mysqlbinlogmysqlbinlog: [ERROR] unknown variable 'default_character_set=utf8mb4'[mysql@ryan mysql]#
解决办法：
在执行命令的时候增加参数 : --no-defaults， 使用如下命令：
[mysql@ryan mysql]# bin/mysqlbinlog --no-defaultsbin/mysqlbinlog Ver 3.4 for linux-glibc2.12 at x86_64Copyright (c) 2000, 2018, Oracle and/or its affiliates.

If no --base64-output[=name] option is given at all, the default is 'auto'. --bind-address=name IP address to bind to. --character-sets-dir=name Directory for character set files. -d, --database=name List entries for just this database (local log only). --rewrite-db=name Rewrite the row event to point so that it can be applied to a new database -#, --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-auth=name Default authentication client-side plugin to use. -D, --disable-log-bin Disable binary log. This is useful, if you enabled --to-last-log and are sending the output to the same MySQL server. This way you could avoid an endless loop. You would also like to use it when restoring after a crash to avoid duplication of the statements you already have. NOTE: you will need a SUPER privilege to use this option. -F, --force-if-open Force if binlog was not closed properly. (Defaults to on; use --skip-force-if-open to disable.) -f, --force-read Force reading unknown binlog events. -H, --hexdump Augment output with hexadecimal and ASCII event dump. -h, --host=name Get the binlog from server. -i, --idempotent Notify the server to use idempotent mode before applying Row Events -l, --local-load=name Prepare local temporary files for LOAD DATA INFILE in the specified directory. -o, --offset=# Skip the first N entries. -p, --password[=name] Password to connect to remote server. --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). -R, --read-from-remote-server Read binary logs from a MySQL server. This is an alias for read-from-remote-master=BINLOG-DUMP-NON-GTIDS. --read-from-remote-master=name Read binary logs from a MySQL server through the COM_BINLOG_DUMP or COM_BINLOG_DUMP_GTID commands by setting the option to either BINLOG-DUMP-NON-GTIDS or BINLOG-DUMP-GTIDS, respectively. If --read-from-remote-master=BINLOG-DUMP-GTIDS is combined with --exclude-gtids, transactions can be filtered out on the master avoiding unnecessary network traffic. --raw Requires -R. Output raw binlog data instead of SQL statements, output is to log files. -r, --result-file=name Direct output to a given file. With --raw this is a prefix for the file names. --secure-auth Refuse client connecting to server if it uses old (pre-4.1.1) protocol. Deprecated. Always TRUE --server-id=# Extract only binlog entries created by the server having the given id. --server-id-bits=# Set number of significant bits in server-id --set-charset=name Add 'SET NAMES character_set' to the output. -s, --short-form Just show regular queries: no extra info and no row-based events. This is for testing only, and should not be used in production systems. If you want to suppress base64-output, consider using --base64-output=never instead. -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 --start-datetime=name Start reading the binlog at first event having a datetime equal or posterior to the argument; the argument must be a date and time in the local time zone, in any format accepted by the MySQL server for DATETIME and TIMESTAMP types, for example: 2004-12-25 11:25:56 (you should probably use quotes for your shell to set it properly). -j, --start-position=# Start reading the binlog at position N. Applies to the first binlog passed on the command line. --stop-datetime=name Stop reading the binlog at first event having a datetime equal or posterior to the argument; the argument must be a date and time in the local time zone, in any format accepted by the MySQL server for DATETIME and TIMESTAMP types, for example: 2004-12-25 11:25:56 (you should probably use quotes for your shell to set it properly). --stop-never Wait for more data from the server instead of stopping at the end of the last log. Implicitly sets --to-last-log but instead of stopping at the end of the last log it continues to wait till the server disconnects. --stop-never-slave-server-id=# The slave server_id used for --read-from-remote-server --stop-never. This option cannot be used together with connection-server-id. --connection-server-id=# The slave server_id used for --read-from-remote-server. This option cannot be used together with stop-never-slave-server-id. --stop-position=# Stop reading the binlog at position N. Applies to the last binlog passed on the command line. -t, --to-last-log Requires -R. Will not stop at the end of the requested binlog but rather continue printing until the end of the last binlog of the MySQL server. If you send the output to the same MySQL server, that may lead to an endless loop. -u, --user=name Connect to the remote server as username. -v, --verbose Reconstruct pseudo-SQL statements out of row events. -v -v adds comments on column data types. -V, --version Print version and exit. --open-files-limit=# Used to reserve file descriptors for use by this program. -c, --verify-binlog-checksum Verify checksum binlog events. --binlog-row-event-max-size=# The maximum size of a row-based binary log event in bytes. Rows will be grouped into events smaller than this size if possible. This value must be a multiple of 256. --skip-gtids Do not preserve Global Transaction Identifiers; instead make the server execute the transactions as if they were new. --include-gtids=name Print events whose Global Transaction Identifiers were provided. --exclude-gtids=name Print all events but those whose Global Transaction Identifiers were provided.Variables (--variable-name=value)and boolean options {FALSE|TRUE} Value (after reading options)--------------------------------- ----------------------------------------base64-output (No default value)bind-address (No default value)character-sets-dir (No default value)database (No default value)rewrite-db (No default value)default-auth (No default value)disable-log-bin FALSEforce-if-open TRUEforce-read FALSEhexdump FALSEhost (No default value)idempotent FALSElocal-load (No default value)offset 0plugin-dir (No default value)port 0read-from-remote-server FALSEread-from-remote-master (No default value)raw FALSEresult-file (No default value)secure-auth TRUEserver-id 0server-id-bits 32set-charset (No default value)short-form FALSEsocket (No default value)ssl TRUEssl-verify-server-cert FALSEssl-ca (No default value)ssl-capath (No default value)ssl-cert (No default value)ssl-cipher (No default value)ssl-key (No default value)ssl-crl (No default value)ssl-crlpath (No default value)tls-version (No default value)start-datetime (No default value)start-position 4stop-datetime (No default value)stop-never FALSEstop-never-slave-server-id -1connection-server-id -1stop-position 18446744073709551615to-last-log FALSEuser (No default value)open-files-limit 64verify-binlog-checksum FALSEbinlog-row-event-max-size 4294967040skip-gtids FALSEinclude-gtids (No default value)exclude-gtids (No default value)[mysql@ryan mysql]#
2. mysqlbinlog 转出来的 SQL 是进过 base64 的，无法直接查看到SQL 语句。故需要进行转换！再多增加一个如下参数，即可：
--base64-output=DECODE-ROWS -v
