mysqlbinlog用法如下：

mysqbinlog mysql.err ? 查詢錯誤日志

當然可以通過添加參數來查看指定內容,如：

mysqlbinlog mysql-bin.000001 ?-d test 只顯示對test數據庫的二進制日志

mysqlbinlog?mysql-bin.000001???-o 3 -r result-file 首先忽略前三個操作，并將日志結果輸出到result-file文件中

mysqlbinlog相關參數：

--base64-output[=name]

Determine when the output statements should be

base64-encoded BINLOG statements: 'never' disables it and

works only for binlogs without row-based events;

'decode-rows' decodes row events into commented SQL

statements if the --verbose option is also given; 'auto'

prints base64 only when necessary (i.e., for row-based

events and format description events); 'always' prints

base64 whenever possible. 'always' is for debugging only

and should not be used in a production system. If this

argument is not given, the default is 'auto'; if it is

given with no argument, 'always' is used.

--character-sets-dir=name

Directory for character set files.

-d, --database=name List entries for just this database (local log only).

--debug-check Check memory and open file usage at exit .

--debug-info Print some debug info at exit.

-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.

-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.

-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.

-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).

--position=# Deprecated. Use --start-position instead.

--protocol=name The protocol to use for connection (tcp, socket, pipe,

memory).

-R, --read-from-remote-server

Read binary logs from a MySQL server.

-r, --result-file=name

Direct output to a given file.

--server-id=# Extract only binlog entries created by the server having

the given 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.

--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-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 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.

在使用mysqlbinlog查看二進制日志時會出現mysqlbinlog: unknown variable 'default-character-set=utf8'

解決辦法：

1、mysqlbinlog --no-defaults mysql-bin.000001

2、修改my.cnf

#default-character-set=utf8

因為mysqlbinlog會重新從my.cnf中讀取，不是從內存中讀取，使用完畢之后，再修改過來即可
