mysqlbinlog \- utility for processing binary log files
.SH "SYNOPSIS"
.HP 35
\fBmysqlbinlog [\fR\fBoptions\fR\fB] \fR\fB\fIlog_file\fR\fR\fB ...\fR
.SH "DESCRIPTION"
.PP
The binary log files that the server generates are written in binary format. To examine these files in text format, use the
\fBmysqlbinlog\fR
utility. You can also use
\fBmysqlbinlog\fR
to read relay log files written by a slave server in a replication setup. Relay logs have the same format as binary log files.
.PP
Invoke
\fBmysqlbinlog\fR
like this:
.sp
.RS 3n
.nf
shell> \fBmysqlbinlog [\fR\fB\fIoptions\fR\fR\fB] \fR\fB\fIlog_file\fR\fR\fB ...\fR
.fi
.RE
.PP
For example, to display the contents of the binary log file named
\fIbinlog.000003\fR, use this command:
.sp
.RS 3n
.nf
shell> \fBmysqlbinlog binlog.0000003\fR
.fi
.RE
.PP
The output includes all events contained in
\fIbinlog.000003\fR. Event information includes the statement executed, the time the statement took, the thread ID of the client that issued it, the timestamp when it was executed, and so forth.
.PP
The output from
\fBmysqlbinlog\fR
can be re\-executed (for example, by using it as input to
\fBmysql\fR) to reapply the statements in the log. This is useful for recovery operations after a server crash. For other usage examples, see the discussion later in this section.
.PP
Normally, you use
\fBmysqlbinlog\fR
to read binary log files directly and apply them to the local MySQL server. It is also possible to read binary logs from a remote server by using the
\fB\-\-read\-from\-remote\-server\fR
option. When you read remote binary logs, the connection parameter options can be given to indicate how to connect to the server. These options are
\fB\-\-host\fR,
\fB\-\-password\fR,
\fB\-\-port\fR,
\fB\-\-protocol\fR,
\fB\-\-socket\fR, and
\fB\-\-user\fR; they are ignored except when you also use the
\fB\-\-read\-from\-remote\-server\fR
option.
.PP
Binary logs and relay logs are discussed further in
Section\ 2.3, \(lqThe Binary Log\(rq, and
Section\ 4.2, \(lqReplication Relay and Status Files\(rq.
.PP
\fBmysqlbinlog\fR

.sp
List entries for just this database (local log only). You can only specify one database with this option \- if you specify multiple
\fB\-\-database\fR
options, only the last one is used. This option forces
\fBmysqlbinlog\fR
to output entries from the binary log where the default database (that is, the one selected by
USE) is
\fIdb_name\fR. Note that this does not replicate cross\-database statements such as
UPDATE \fIsome_db.some_table\fR SET foo='bar'

Disable binary logging. This is useful for avoiding an endless loop if you use the
\fB\-\-to\-last\-log\fR
option and are sending the output to the same MySQL server. This option also is useful when restoring after a crash to avoid duplication of the statements you have logged.
.sp
This option requires that you have the
SUPER
privilege. It causes
\fBmysqlbinlog\fR
to include a
SET SQL_LOG_BIN=0
statement in its output to disable binary logging of the remaining output. The
SET
statement is ineffective unless you have the
SUPER
privilege.
.TP 3n
\(bu
\fB\-\-force\-read\fR,

With this option, if
\fBmysqlbinlog\fR

\fBmysqlbinlog\fR
stops if it reads such an event.
.TP 3n
\(bu
\fB\-\-hexdump\fR,

\fIcannot\fR
have a space between the option and the password. If you omit the
\fIpassword\fR
value following the
\fB\-\-password\fR

Start reading the binary log at the first event having a timestamp equal to or later than the

value is relative to the local time zone on the machine where you run
\fBmysqlbinlog\fR. The value should be in a format accepted for the

.sp

\(bu
\fB\-\-stop\-datetime=\fR\fB\fIdatetime\fR\fR
.sp
Stop reading the binary log at the first event having a timestamp equal or posterior to the

\fB\-\-start\-datetime\fR
option for information about the

.TP 3n
\(bu
\fB\-\-start\-position=\fR\fB\fIN\fR\fR

.TP 3n
\(bu
\fB\-\-stop\-position=\fR\fB\fIN\fR\fR

.TP 3n
\(bu
\fB\-\-to\-last\-log\fR,

Do not stop at the end of the requested binary log from a MySQL server, but rather continue printing until the end of the last binary log. If you send the output to the same MySQL server, this may lead to an endless loop. This option requires

You can also set the following variable by using
\fB\-\-\fR\fB\fIvar_name\fR\fR\fB=\fR\fB\fIvalue\fR\fR

It is also possible to set variables by using

or
\fB\-O \fR\fB\fIvar_name\fR\fR\fB=\fR\fB\fIvalue\fR\fR
syntax.
\fIThis syntax is deprecated\fR.
.PP
You can pipe the output of
\fBmysqlbinlog\fR
into the
\fBmysql\fR
client to execute the statements contained in the binary log. This is used to recover from a crash when you have an old backup (see
Section\ 6.1, \(lqDatabase Backups\(rq). For example:
.sp
.RS 3n
.nf
shell> \fBmysqlbinlog binlog.000001 | mysql\fR
.fi
.RE
.PP
Or:
.sp
.RS 3n
.nf
shell> \fBmysqlbinlog binlog.[0\-9]* | mysql\fR
.fi
.RE
.PP
You can also redirect the output of
\fBmysqlbinlog\fR
to a text file instead, if you need to modify the statement log first (for example, to remove statements that you do not want to execute for some reason). After editing the file, execute the statements that it contains by using it as input to the
\fBmysql\fR
program.
.PP
\fBmysqlbinlog\fR
has the
\fB\-\-start\-position\fR
option, which prints only those statements with an offset in the binary log greater than or equal to a given position (the given position must match the start of one event). It also has options to stop and start when it sees an event with a given date and time. This enables you to perform point\-in\-time recovery using the
\fB\-\-stop\-datetime\fR
option (to be able to say, for example,
\(lqroll forward my databases to how they were today at 10:30 a.m.\(rq).
.PP
If you have more than one binary log to execute on the MySQL server, the safe method is to process them all using a single connection to the server. Here is an example that demonstrates what may be
\fIunsafe\fR:
.sp
.RS 3n
.nf
shell> \fBmysqlbinlog binlog.000001 | mysql # DANGER!!\fR
shell> \fBmysqlbinlog binlog.000002 | mysql # DANGER!!\fR
.fi
.RE
.PP
Processing binary logs this way using different connections to the server causes problems if the first log file contains a
CREATE TEMPORARY TABLE
statement and the second log contains a statement that uses the temporary table. When the first
\fBmysql\fR
process terminates, the server drops the temporary table. When the second
\fBmysql\fR
process attempts to use the table, the server reports
\(lqunknown table.\(rq
.PP
To avoid problems like this, use a
\fIsingle\fR
connection to execute the contents of all binary logs that you want to process. Here is one way to do so:
.sp
.RS 3n
.nf
shell> \fBmysqlbinlog binlog.000001 binlog.000002 | mysql\fR
.fi
.RE
.PP
Another approach is to write all the logs to a single file and then process the file:
.sp
.RS 3n
.nf
shell> \fBmysqlbinlog binlog.000001 >  /tmp/statements.sql\fR
shell> \fBmysqlbinlog binlog.000002 >> /tmp/statements.sql\fR
shell> \fBmysql \-e "source /tmp/statements.sql"\fR
.fi
.RE
.PP
\fBmysqlbinlog\fR
can produce output that reproduces a
LOAD DATA INFILE
operation without the original data file.
\fBmysqlbinlog\fR
copies the data to a temporary file and writes a
LOAD DATA LOCAL INFILE
statement that refers to the file. The default location of the directory where these files are written is system\-specific. To specify a directory explicitly, use the
\fB\-\-local\-load\fR
option.
.PP
Because
\fBmysqlbinlog\fR
converts
LOAD DATA INFILE
statements to
LOAD DATA LOCAL INFILE
statements (that is, it adds
LOCAL), both the client and the server that you use to process the statements must be configured to allow
LOCAL
capability. See
Section\ 3.4, \(lqSecurity Issues with LOAD DATA LOCAL\(rq.

.it 1 an-trap

\fBWarning\fR
.PP
The temporary files created for
LOAD DATA LOCAL
statements are
\fInot\fR
automatically deleted because they are needed until you actually execute those statements. You should delete the temporary files yourself after you no longer need the statement log. The files can be found in the temporary file directory and have names like
\fIoriginal_file_name\-#\-#\fR.
.PP
The
\fB\-\-hexdump\fR
option produces a hex dump of the log contents in comments:
.sp
.RS 3n
.nf
shell> \fBmysqlbinlog \-\-hexdump master\-bin.000001\fR

LOG_EVENT_BINLOG_IN_USE_F

Log file correctly closed. (Used only in
                    FORMAT_DESCRIPTION_EVENT.) If
                    this flag is set (if the flags are, for example,
                    '01 00') in a
                    FORMAT_DESCRIPTION_EVENT, the log
                    file has not been properly closed. Most probably
                    this is because of a master crash (for example, due
                    to power failure).
