我让MySQL在MAMP下工作，现在它不再工作，我不知道为什么。我正在尝试卸载所有MySQL，我想设置它，当我键入mysql时，mysql数据库将启动，当我键入localhost / phpMyAdmin时，phpMyAdmin应该启动。
然而，我确实遇到了这样的问题：
1）
brew install mysql
SEICCN-3:~ stefanieness$ brew install mysql
==> Downloading https://downloads.sf.net/project/machomebrew/Bottles/mysql-5.6.21.mavericks.bottle.tar.gz
Already downloaded: /Library/Caches/Homebrew/mysql-5.6.21.mavericks.bottle.tar.gz
==> Pouring mysql-5.6.21.mavericks.bottle.tar.gz
==> Caveats
A "/etc/my.cnf" from another install may interfere with a Homebrew-built
server starting up correctly.
To connect:
mysql -uroot
To have launchd start mysql at login:
ln -sfv /usr/local/opt/mysql/*.plist ~/Library/LaunchAgents
Then to load mysql now:
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
Or, if you don't want/need launchctl, you can just run:
mysql.server start

直到无穷大。
2）如何设置MySQL root密码和mysqladmin密码。我经常收到错误ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
After some trials, I go `ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)` but still the same error.
3）当我输入localhost时，我可以使用它，但是当我输入：localhost/phpMyAdmin时，它只显示文件夹结构。就像那样：https://www.dropbox.com/s/9wnacznpk80s54j/Screenshot%202014-11-20%2015.48.30.png?dl=0
非常感谢你！
