i get mysql.dll error something.

the port i use in mysql, does it have to be the same as in Ruby? in  
Ruby the standard is 3000.

what is better to change if i need to change something? other  
programing languages use port 8080.  
should i keep them all the same?

marvelously informative, that.

and the MySQL default is 3306. Different processes need to listen on  
_different_ ports; unless you have a good reason to change them from  
the default, don’t 🙂

libmysql.dll is missing. Google it. You will find it. Chuck it in  
C:\Windows\system32. No, it’s not a virus.

This case has already posted many times here. The matter is, user always  
lazy to search their question to get answer in this forum, we put search  
query at the bottom of left menu. Here i repost again the answer :

[1] gem install mysql  
[2] you will see like error syntac but dont pay attention to it  
[3] find LIBMYSQL.DLL from your mysql/bin folder in your mysql folder  
not ruby folder.  
[4] copy & paste that file to ruby/bin  
[5] restart your server or console, if you are already run it.

Then Cheer 🙂
