InnoDB: Some operating system error numbers are described at

InnoDB: http://dev.mysql.com/doc/refman/5.5/en/operating-system-error-codes.html

InnoDB: File name ./ib_logfile0

InnoDB: File operation call: 'aio read'.

在innodb配置节的最后加上innodb_flush_method=normal就可以了

# MySQL Server Instance Configuration File# ----------------------------------------------------------------------# Generated by the MySQL Server Instance Configuration Wizard### Installation Instructions# ----------------------------------------------------------------------## On Linux you can copy this file to /etc/my.cnf to set global options,# mysql-data-dir/my.cnf to set server-specific options# ( for this installation) or to# ~/.my.cnf to set user-specific options.## On Windows you should keep this file in the installation directory # of your server (e.g. C:/Program Files/MySQL/MySQL Server X.Y). To# make sure the server reads the config file use the startup option # "--defaults-file". ## To run run the server from the command line, execute this in a # command line shell, e.g.# mysqld --defaults-file="C:/Program Files/MySQL/MySQL Server X.Y/my.ini"## To install the server as a Windows service manually, execute this in a # command line shell, e.g.# mysqld --install MySQLXY --defaults-file="C:/Program Files/MySQL/MySQL Server X.Y/my.ini"## And then execute this in a command line shell to start the server, e.g.# net start MySQLXY### Guildlines for editing this file# ----------------------------------------------------------------------## In this file, you can use all long options that the program supports.# If you want to know the options a program supports, start the program# with the "--help" option.## More detailed information about the individual options can also be# found in the manual.### CLIENT SECTION# ----------------------------------------------------------------------## The following options will be read by MySQL client applications.# Note that only client applications shipped by MySQL are guaranteed# to read this section.
