最近一星期全在捣鼓mysql数据恢复，那个头大啊…………

?

网上找了找资料说使用mysqlbinlog 可以恢复。就试了试。

?

查询是否开启日志

?

show variables like 'log_bin';

?

显示为on，恭喜你开启了日志

?

下面就是恢复数据了

?

在恢复前还是先了解下mysqlbinlog的使用吧

?

在命令行中打开mysql的bin目录，执行mysqlbinlog -？

?

{mysqlhome}\bin>mysqlbinlog -?

Dumps a MySQL binary log in a format usable for viewing or for piping to
the mysql command line client.

Usage: mysqlbinlog [options] log-files
  -?, --help          Display this help and exit.
  --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
                      pseudo-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).  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).
  --debug-check       Check memory and open file usage at exit .
  --debug-info        Print some debug info at 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.
  -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 --exc
