文章标签 mysql bin 恢复 mysql sql 命令行 文章分类 MySQL 数据库

1：开启binlog日志记录修改mysql配置文件mysql.ini，在[mysqld]节点下添加

复制代码代码如下:

# 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

复制代码代码如下:

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

复制代码代码如下:

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

复制代码代码如下:

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

复制代码代码如下:

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

复制代码代码如下:

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 按指定位置导出：Sql代码

复制代码代码如下:

c:\mysql\bin\>mysqlbinlog --start-position=185 --stop-position=338 e:/log/logbin.000001 > e:/log/log3.txt

2.3 按指定时间导出：Xml代码

复制代码代码如下:

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：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

复制代码代码如下:
