我的数据库的表是INNODB类型,我在MY.CNF中开起了INNODB如下: # Uncomment the following if you are using InnoDB tables innodb_data_home_dir = /usr/local/mysql/var/ innodb_data_file_path = ibdata1:2000M;ibdata2:10M:autoextend innodb_log_group_home_dir = /usr/local/mysql/var/ innodb_log_arch_dir = /usr/local/mysql/var/ # You can set .._buffer_pool_size up to 50 - 80 % # of RAM but beware of setting memo...

关键数据，因系统崩溃而丢失，而系统后来连mount都不行，后来请高手将数据寻找到节点dump出来了，但是将ibdata1文件恢复到安装好的系统上后，结果mysql连启动都无法启动，其中.err文件报错如下， 070604 23:42:18 mysqld started 070604 23:42:18 InnoDB: database was not shut down normally! InnoDB: Starting crash recovery. InnoDB: Reading tablespace information from the .ibd files... InnoDB: Restoring possible h...

my.cnf里我没有配置innodb。 但因为数据库里有innodb的表，可能系统按照默认的方式来运行innodb。 怎么通过现在的ibdata1文件来恢复数据呢？

系统内核是2.6.15, mysql版本是5.0.20 现在系统是装在一块256MB的CF卡上，因为担心ibdata1,ib_logfile0,ib_logfile1这几个文件太占空间，而且时间久了，CF卡就放不下了，所以又装了一块硬盘，希望能够把这几个文件直接在这块硬盘上生成，而不是在CF卡上。请问该如何设置？谢谢！！ [ 本帖最后由 setsuna 于 2006-9-12 12:47 编辑 ]

今天下午有个哥们问我这个问题。 做了点简单的测试，步骤如下： 1、导出你的INNODB数据到自己的目录。 2、然后停掉mysqlD。 3、删除掉目录下的ib_logfile0,ib_logfile1,ibdata1...等。 4、修改my.cnf。添加比如： innodb_data_file_path = ibdata1:10M;ibdata2:10M;ibdata3:20M;ibdata4:30M:autoextend:max:1000M 原来是： #innodb_data_file_path = ibdata1:10M;ibdata2:10M:autoextend 5、重新启动数据库。 6、导入备份...
