重装mysql无法启动服务的问题

之前装的mysql5.1,但是经过系统还原后服务没有了,干脆升级到5.5,但是安装好了,配置时最后一步就是启动不了!

查看日志:programdata/data/pc.err发现:

111121 22:16:50  InnoDB: Log file .\ib_logfile0 did not exist: new to be created
InnoDB: Setting log file .\ib_logfile0 size to 10 MB
InnoDB: Database physically writes the file full: wait...
111121 22:16:50  InnoDB: Log file .\ib_logfile1 did not exist: new to be created

在网上一查,原来要将ib_logfile0,ib_logfile1,还有ibdata1这三个文件删掉才行,它们分别在data和programdata目录中(在配置时由你指定的)。

但是最后还是连不上,即使是服务启动了,就是连不上。

总是在第四步的security setting上提示1045 Error,死活不能连接'root'@'localhost' password[YES]

找这篇文章来:http://marclee.blog.163.com/blog/static/40317017201157101349210/ 任然不行。

没办法,退回去下载5.1的,安装顺利。

╮(╯▽╰)╭,还是老老实实用5.1吧!
