mysql数据恢复工具
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 -？

Other names may be trademarks of their respectiveowners.Dumps a MySQL binary log in a format usable for viewing or for piping tothe 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 --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. --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. --shared-memory-base-name=name Base name of shared memory. -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-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 stop-never --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 print Global Transaction Identifier information (SET GTID_NEXT=... etc). --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)debug-check FALSEdebug-info FALSEdefault-auth (No default value)disable-log-bin FALSEforce-if-open TRUEforce-read FALSEhexdump FALSEhost (No default value)local-load (No default value)offset 0plugin-dir (No default value)port 6306read-from-remote-server FALSEread-from-remote-master (No default value)raw FALSEresult-file (No default value)server-id 0set-charset (No default value)shared-memory-base-name (No default value)short-form FALSEsocket (No default value)start-datetime (No default value)start-position 4stop-datetime (No default value)stop-never FALSEstop-never-slave-server-id 65535stop-position 18446744073709551615to-last-log FALSEuser (No default value)open-files-limit 18432verify-binlog-checksum FALSEbinlog-row-event-max-size 4294967040skip-gtids FALSEinclude-gtids (No default value)exclude-gtids (No default value)?如果英文不好可以借助google翻译，有道翻译或直接在百度中找下相关资料即可这里给个参考

其实这篇文章说的很好了，就是排版上有点糟。
?
知道参数了 就可以恢复了
mysqlbinlog? --startdate=“”? 日志目录/mysql-bin-000012 >mysql -uroot -p 数据库
?
恢复的详细介绍可参考
http://topic.csdn.net/u/20090608/20/e50feb34-0a07-4675-80d4-2eac35973286.html
?
当然参数可以根据需要自己添加
?
到处为sql（ 其中-v -v 低版本是不支持的，需要5.1.18以上）
mysqlbinlog -uroot -p -v? -v -d 数据库的名称? 日志目录/mysql-bin-000012 > sql.sql
?
?
但是由于使用的mysql数据库时间过长，备份日志不全，没办法就把日志中的删除语句改为了 蒲绒的sql插入语句
?
但是发现在处理大字段上出现了问题，在sql中大字段都是‘\x00\x00’形式
?
导入数据库时 报? Unkown? command ‘\x’? 至今未得到解决 ，哪位如果处理过类似问题，还希望多多指教！！
