虚拟机关机后第二天mysql起不来，回想一下我关机前和关机后的操作发现：关机前没关闭mysqld服务就直接init 0了，关机后将虚拟机内存由1G降到724M。笔者保证再也做过别的骚操作了。

貌似是innodb引擎错误，还有就是分配内存失败，内存分配失败会导致innodb错误吗，还是断电导致的？不得而知！！！
百度答案花样百出，最后试着在/etc/my.cnf中加入下列一行再重启
tmp_table_size=500M
***************************************
PS:下列谷歌出来的方法笔者没试过，可以一试：
主要是innodb日志大小不对造成的 innodb_buffer_pool_size=512M innodb_log_file_size=128M 把以上几个参数调大点，然后把ibdata1，ib_logfile0，ib_logfile1这三个文件删除后，再重启服务就好了。 如果还是不行，在my.ini文件里还需要加入tmpdir="usr/tmp"这样的路径，因为innodb还需要一个临时的文件缓存区。
****************************************
事实证明没用，该句只是用来设置内部（内存中）临时表的最大大小
重启后仍然报错，网上解决方法一般是：
问题描述： 非正常关闭mysql，同时更改了my.cnf 导致启动时不支持innodb，出现如下错误： [ERROR] Plugin ‘InnoDB’ init function returned error. [ERROR] Plugin ‘InnoDB’ registration as a STORAGE ENGINE failed. [ERROR] Unknown/unsupported table type: InnoDB [ERROR] Aborting 解决办法： 删除log文件和data的初始化文件 重新运行mysql_install_db 再启动
笔者并没有删除文件，只是将/data/dbdata下的三个文件移动到/tmp下备份了，万一以后用得着呢？
三个文件：ibdata1、ib_logfile0、ib_logfile1
再用mysql-install-db初始化
但是这一系列操作后mysqld仍然启动不了，直接关机，将虚拟机内存调回1G，没想到居然好了，可以成功启动mysqld服务啦！

但是这还不够，进入数据库后出现了奇怪的一幕：数据库和表都在，却打不开，什么鬼

各种表都不能访问，包括下列五个表：
innodb_table_stats innodb_index_stats slave_master_info slave_relay_log_info slave_worker_info
之前备份过旧的ibdata1文件
虽然重新初始化之后,数据库会自动创建一个ibdata1文件,但是上述系统表也是innodb引擎,所以不能访问了.
关闭mysql服务后，尝试着将之前备份的ibdata1恢复。结果很神奇的解决了这个问题！数据库能成功读写了，但查看日志文件后发现还是有问题：
