MySQL install on OSX, I want to start again, is it safe to delete all mysql folders?

I want to start again with attempting to install MySQL on OSX, I typed this to find all folders find / -name mysql. Is it safe just to delete all of 开发者_JAVA百科the folders that I found?

/opt/local/include/mysql5/mysql
/opt/local/lib/mysql5/bin/mysql
/opt/local/lib/mysql5/mysql
/opt/local/share/mysql5/mysql
/opt/local/var/db/mysql5/mysql
/opt/local/var/macports/software/mysql5/5.1.40_0/opt/local/include/mysql5/mysql

Thanks

If you don't care about any of the data that might be in there, then yes.

You may also want to find and destroy my.ini which should be in /etc/ or some configuration directory.
