加log恢复功能

vi /etc/my.cnf

要想通过日志恢复数据库，在你的my.cnf文件里应该有如下的定义，log-bin=mysql-bin，这个是必须的.binlog-do-db=db_test,这个是指定哪些数据库需要日志，如果有多个数据库就每行一个，如果不指定的话默认就是所有数据库.
[mysqld]
log-bin=mysql-bin
binlog-do-db=db_test
binlog-do-db=db_test2

expire_logs_day=3设置日志的过期天数,过了指定的天数,会自动删除

--------------------------------------

reset master(清空所有的二进制日志文件)
purge master logs to 'bintest.000006';(删除bintest.000006之前的二进制日志文件)

purge master logs before '2007-08-10 04:07:00'(删除该日期之前的日志)

1.还原全部数据库:

(1) mysql命令行：mysql>source f:\all.sql

(2) 系统命令行： mysql -uroot -p123456 <f:\all.sql
