mysqlbinlog用法如下：
mysqbinlog mysql.err 查询错误日志
当然可以通过添加参数来查看指定内容,如：
mysqlbinlog mysql-bin.000001 -d test 只显示对test数据库的二进制日志
mysqlbinlog mysql-bin.000001 -o 3 -r result-file 首先忽略前三个操作，并将日志结果输出到result-file文件中
mysqlbinlog相关参数：
--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查看二进制日志时会出现mysqlbinlog: unknown variable 'default-character-set=utf8'
解决办法：
1、mysqlbinlog --no-defaults mysql-bin.000001
2、修改my.cnf
#default-character-set=utf8
因为mysqlbinlog会重新从my.cnf中读取，不是从内存中读取，使用完毕之后，再修改过来即可
