解决办法参考:
http://www.jb51.net/article/27009.htm

/etc/init.d/mysqld stop
//停止mysql
mv ib_logfile0 ib_logfile0.back
mv ib_logfile1 ib_logfile1.back
重命名ib_logfile文件

vi my.cnf
修改innodb_log_file_size字段
#
my-innodb-heavy-4G.cnf的话(log file 的大小是256M:innodb_log_file_size = 256M)
#

/etc/init.d/mysqld start
//开启mysql

cat 10isp.err
//查看日志文件 是否再有错误
