1.根据binlog解析出所有ring数据库的所有sql
[mysql@localhost ]$ mysqlbinlog --no-defaults --database=ring --start-datetime="2005-04-20 9:55:00" --stop-datetim="2009-04-08 08:05:00" /u01/mysql/log/mysql-bin.000005 > /u01/mysql/log/mysql_restore5.sql
[mysql@localhost ]$ ls -l /u01/mysql/log/mysql_restore5.sql
-rw-r--r-- 1 mysql dba 407 Apr 8 15:33 /u01/mysql/log/mysql_restore5.sql
--start-datetime=datetime 从哪个点开始解析
--stop-datetim=datetime 从哪个点停止解析
--database=ring 指定需要解析哪个数据库，只提取某个数据库的sql语句
--如果有多个binlog的话需要解析多次，需要解析所有的binlog
2.重新在数据库中执行
[mysql@localhost ]$ mysql -u root < /u01/mysql/log/mysql_restore5.sql
ERROR 1062 (23000) at line 2559580: Duplicate entry 175754263-140 for key 1 --恢复过程中出现主键冲突，导入失败
3.删除已经恢复的数据，重新恢复一遍
[mysql@localhost ]$ mysql -u root
Welcome to the MySQL monitor. Commands end with ; or g.
Your MySQL connection id is 7647

[mysql@localhost ]$ mysql -u root -f < /u01/mysql/log/mysql_restore5.sql -f参数：忽略错误继续

恢复成功，有部分数据冲突需要开发自己去处理了。
MySQL利用binlog来恢复数据库
