1：开启binlog日志记录
修改mysql配置文件mysql.ini，在[mysqld]节点下添加
# log-bin
log-bin = E:/log/logbin.log
路径中不要包含中文和空格。重启mysql服务。通过命令行停止和启动mysql服务
c:\>net stop mysql;
c:\>net start mysql;
进入命令行进入mysql并查看二进制日志是否已经启动
Sql代码
mysql>show variables like 'log_%';
日志成功开启后，会在E:/log/目录下创建logbin.index和logbin.000001两个文件。logbin.000001就是数据库的备份文件，以后就可以通过此文件对数据库进行恢复操作。
2：查看备份的二进制文件
Sql代码
c:\mysql\bin\>mysqlbinlog e:/log/logbin.000001
日后记录的操作多了，命令行方式基本就用不上了。可以使用将日志导出文件的方式来查看日志内容
2.1 导出
Xml代码
c:\mysql\bin\>mysqlbinlog e:/log/logbin.000001 > e:/log/log.txt
">": 导入到文件中; ">>": 追加到文件中
如果有多个日志文件
Sql代码
c:\mysql\bin\> mysqlbinlog e:/log/logbin.000001 > e:/log/log.sql
c:\mysql\bin\> mysqlbinlog e:/log/logbin.000002 >> e:/log/log.sq
2.2 按指定位置导出：
Sql代码
c:\mysql\bin\>mysqlbinlog --start-position=185 --stop-position=338 e:/log/logbin.000001 > e:/log/log3.txt
2.3 按指定时间导出：
Xml代码
c:\mysql\bin\>mysqlbinlog --start-datetime="2010-01-07 11:25:56" --stop-datetime="2010-01-07 13:23:50" e:/log/logbin.000001 > e:/log/log_by_date22.txt
3：从备份恢复数据库
做了一次更新操作，之后日志的内容如下：
Sql代码

3.1 恢复：
Sql代码
c:\mysql\bin\>mysqlbinlog e:/log/logbin.000001 | mysql -u root -p
3.2 按指定位置恢复：
Sql代码
c:\mysql\bin\>mysqlbinlog --start-position=185 --stop-position=338 e:/log/logbin.000001 | mysql -u root -p
3.3 按指定时间恢复：
Xml代码
c:\mysql\bin\>mysqlbinlog --start-datetime="2010-01-07 11:25:56" --stop-datetime="2010-01-07 13:23:50" e:/log/logbin.000001 | mysql -u root -p
3.4 通过导出的脚本文件恢复
Sql代码
c:\mysql\bin\>mysql -e "source e:/log/log.sql"
4.其他常用操作
4.1 查看所有日志文件
Sql代码
mysql>show master logs;
4.2 当前使用的binlog文件
Sql代码
mysql>show binlog events \g;
4.3 产生一个新的binlog日志文件
Sql代码
mysql>flush logs;
4.4 删除所有二进制日志，并从新开始记录（注意：reset master命令会删除所有的二进制日志）
Sql代码
mysql > flush logs;
mysql > reset master;
4.5 快速备份数据到sql文件
Sql代码
c:\mysql\bin>mysqldump -u root -p --opt --quick interactive > e:/log/mysqldump.sql
为了方便查看，把从脚本恢复的命令在写一次
Sql代码
c:\mysql\bin\>mysql -e "source e:/log/mysqldump.sql"
