LOL

But i managed to reset the password following this video, very good one.

Put it here in case you guys make the stupid mistake as i did today :)

windows:

netstat -aon  //找出哪个线程在占用你的80端口，eg.35454线程在占用80端口。

taskkill /pid 35454 //结束占用80端口的程序，现在80端口就可用了。

linux:

lsof -P | grep 80

kill 35454

select * from posts where date(created) bettwen date(2009-05-13) and date(2009-05-16)

除了date()，还有year(),month(),day()可以使用。year(2009-05-13) 返回2009，month(2009-05-13)返回05，day(2009-05-13)返回13

Happy Coding…
