InnoDB: The log sequence number in ibdata files does not match

InnoDB: The log sequence number in ibdata files does not match
InnoDB的：在ibdata文件的日志序列号不匹配

可能ibdata文件损坏了
解决办法如下:
在my.cny 的[mysqld]中加入

# Size of each log file in a log group. You should set the combined size

# of log files to about 25%-100% of your buffer pool size to avoid

# unneeded buffer pool flush activity on log file overwrite. However,

# note that a larger logfile size will increase the time needed for the

# recovery process.
    innodb_log_file_size=10M


# Number of threads allowed inside the InnoDB kernel. The optimal value

# depends highly on the application, hardware as well as the OS
    #
scheduler properties. A too high value may lead to thread thrashing.

innodb_thread_concurrency=8

innodb_force_recovery = 4

max_allowed_packet=16M

MySQL · 引擎特性 · InnoDB redo log漫游（转）

前言 InnoDB 有两块非常重要的日志,一个是undo log,另外一个是redo log,前者用来保证事务的原子性以及InnoDB的MVCC,后者用来保证事务的持久性. 和大多数关系型数据库一样,InnoDB记录了对数据文件的物理更改,并保证总是日志先行,也就是所谓的WAL,即在持久化数据文件前,保证之前的redo日志已经写到磁盘. LSN(log sequence number) 用于记录日志序号,它是一个不断递增的 unsigned long long 类型整数.在 InnoDB 的日志

相较于Oracle的在线调整redo日志的数目和大小,mysql这点则有所欠缺,即使目前的mysql80版本,也不能对innodb redo日志的数目和大小进行在线调整,下面仅就mysql调整innodb redo log files数目和大小的具体方法和步骤进行说明.1. 停止mysql服务器,并确信对其进行了正常关闭:2. 编辑my.cnf 文件以对其中的redo log file相关配置进行调整. 为了改变redo log file的大小,需对选项innodb_log_file_size进

MySQL InnoDB redo Log 浅析

MySQL的InnoDB存储引引擎的物理文件存储体系中,除了实际的数据文件(ibd, ibdata)之外,还有两个非常重要的日志系统,分别是redo日志和undo日志. 跟Oracle类似, redo log记录了对实际数据文件的物理变更(数据文件的什么位置数据做了如何的变更).InnoDB也是采用了WAL(日志优先落盘),也就是说在实际数据文件的修改落盘之前redo日志已经落盘,从而来保证事务的持久性.Undo日志用来保证事务的原子性和MVCC,所有的undo操作产身的数据文件的变更也会记录到
