MySQL数据库恢复(使用mysqlbinlog命令)
小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.
1：開啟binlog日志記錄?
修改mysql配置文件mysql.ini，在[mysqld]節(jié)點(diǎn)下添加?
# log-bin?
log-bin = E:/log/logbin.log?
路徑中不要包含中文和空格。重啟mysql服務(wù)。通過命令行停止和啟動(dòng)mysql服務(wù)?
c:\>net stop mysql;?
c:\>net start mysql;?
進(jìn)入命令行進(jìn)入mysql并查看二進(jìn)制日志是否已經(jīng)啟動(dòng)?
Sql代碼?
mysql>show variables like 'log_%';?
日志成功開啟后，會(huì)在E:/log/目錄下創(chuàng)建logbin.index和logbin.000001兩個(gè)文件。logbin.000001就是數(shù)據(jù)庫的備份文件，以后就可以通過此文件對(duì)數(shù)據(jù)庫進(jìn)行恢復(fù)操作。?
2：查看備份的二進(jìn)制文件?
Sql代碼?
c:\mysql\bin\>mysqlbinlog e:/log/logbin.000001?
日后記錄的操作多了，命令行方式基本就用不上了。可以使用將日志導(dǎo)出文件的方式來查看日志內(nèi)容?
2.1 導(dǎo)出?
Xml代碼?
c:\mysql\bin\>mysqlbinlog e:/log/logbin.000001 > e:/log/log.txt?
">": 導(dǎo)入到文件中; ">>": 追加到文件中?
如果有多個(gè)日志文件?
Sql代碼?
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 按指定位置導(dǎo)出：?
Sql代碼?
c:\mysql\bin\>mysqlbinlog --start-position=185 --stop-position=338 e:/log/logbin.000001 > e:/log/log3.txt?
2.3 按指定時(shí)間導(dǎo)出：?
Xml代碼?
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：從備份恢復(fù)數(shù)據(jù)庫?
做了一次更新操作，之后日志的內(nèi)容如下：?
Sql代碼?
