《Mysql應(yīng)用MySQL數(shù)據(jù)庫(kù)恢復(fù)(使用mysqlbinlog命令)》要點(diǎn)：
本文介紹了Mysql應(yīng)用MySQL數(shù)據(jù)庫(kù)恢復(fù)(使用mysqlbinlog命令)，希望對(duì)您有用。如果有疑問(wèn)，可以聯(lián)系我們。
1：開(kāi)啟binlog日志記錄
修改mysql配置文件mysql.ini,在[mysqld]節(jié)點(diǎn)下添加
代碼如下:
# 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(guò)命令行停止和啟動(dòng)mysql服務(wù)
代碼如下:
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
代碼如下:
mysql>show variables like 'log_%';
日志成功開(kāi)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(kù)的備份文件,以后就可以通過(guò)此文件對(duì)數(shù)據(jù)庫(kù)進(jìn)行恢復(fù)操作.
2：查看備份的二進(jìn)制文件
Sql代碼
代碼如下:
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(lái)查看日志內(nèi)容
2.1 導(dǎo)出
Xml代碼
代碼如下:
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
代碼如下:
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
代碼如下:
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
代碼如下:
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(kù)
做了一次更新操作,之后日志的內(nèi)容如下：
Sql代碼
代碼如下:

/*!50003 SET @OLD_COMPLETION_TYPE=@@COMPLETION_TYPE,COMPLETION_TYPE=0*/;

3.1 恢復(fù)：
Sql代碼
代碼如下:
c:\mysql\bin\>mysqlbinlog e:/log/logbin.000001 | mysql -u root -p
3.2 按指定位置恢復(fù)：
Sql代碼
代碼如下:
c:\mysql\bin\>mysqlbinlog --start-position=185 --stop-position=338 e:/log/logbin.000001 | mysql -u root -p
3.3 按指定時(shí)間恢復(fù)：
Xml代碼
代碼如下:
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 通過(guò)導(dǎo)出的腳本文件恢復(fù)
Sql代碼
代碼如下:
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代碼
代碼如下:
mysql>show master logs;
4.2 當(dāng)前使用的binlog文件
Sql代碼
代碼如下:
mysql>show binlog events \g;
4.3 產(chǎn)生一個(gè)新的binlog日志文件
Sql代碼
代碼如下:
mysql>flush logs;
4.4 刪除所有二進(jìn)制日志,并從新開(kāi)始記錄(注意：reset master命令會(huì)刪除所有的二進(jìn)制日志)
Sql代碼
代碼如下:
mysql > flush logs;
mysql > reset master;
4.5 快速備份數(shù)據(jù)到sql文件
Sql代碼
代碼如下:
c:\mysql\bin>mysqldump -u root -p --opt --quick interactive > e:/log/mysqldump.sql
為了方便查看,把從腳本恢復(fù)的命令在寫(xiě)一次
Sql代碼
代碼如下:
c:\mysql\bin\>mysql -e "source e:/log/mysqldump.sql"
