我刚开始尝试在本地机器上学习node.js和mysql。我用自制软件安装了mysql。
尝试设置根目录的密码时，得到以下响应：

Thaddeuss-iMac➜  ~  ᐅ  mysqladmin -u root password 'password'

mysqladmin: connect to server at 'localhost' failed

error: 'Access denied for user 'root'@'localhost' (using password: NO)'

但是，如果试图以这种方式设置密码，似乎已经有了密码：

Thaddeuss-iMac➜  ~  ᐅ  mysqladmin -u root -p 

password

Enter password: 

mysqladmin: connect to server at 'localhost' failed

error: 'Access denied for user 'root'@'localhost' (using password: YES)'

最近的卸载行如下：

Thaddeuss-iMac➜  ~  ᐅ  sudo rm /usr/local/mysql
Password:

Thaddeuss-iMac➜  ~  ᐅ  sudo rm -rf /usr/local/mysql*

Thaddeuss-iMac➜  ~  ᐅ  sudo rm -rf /Library/StartupItems/MySQLCOM

Thaddeuss-iMac➜  ~  ᐅ  sudo rm -rf /Library/PreferencePanes/My*

Thaddeuss-iMac➜  ~  ᐅ  rm -rf ~/Library/PreferencePanes/My*
zsh: no matches found: /Users/thaddeuspinch/Library/PreferencePanes/My*

Thaddeuss-iMac➜  ~  ᐅ  sudo rm -rf /Library/Receipts/mysql*
zsh: no matches found: /Library/Receipts/mysql*

Thaddeuss-iMac➜  ~  ᐅ  sudo rm -rf 
/Library/Receipts/MySQL*
zsh: no matches found: /Library/Receipts/MySQL*

Thaddeuss-iMac➜  ~  ᐅ  sudo rm -rf /private/var/db/receipts/*mysql*

我已经通过多种方式卸载了mysql，并通过自制和oracle的.dmg重新安装了osx版本（10.12.6）。总是得到同样的问题。任何建议都将不胜感激。
