我正在尝试在我的MAC OS X Yosemite上重新安装mysql.为此，我按照以下说明进行操作

I'm trying to reinstall mysql on my MAC OS X Yosemite. for this I followed the instruction as mentioned below

sudo rm /usr/local/mysql
sudo rm -rf /usr/local/mysql*
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/MySQL*
vim /etc/hostconfig and removed the line MYSQLCOM=-YES-
rm -rf ~/Library/PreferencePanes/MySQL*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*
sudo rm -rf /var/db/receipts/com.mysql.*

我也尝试过

brew uninstall mysql

在此之后，我使用命令brew install mysql使用homebrew安装了mysql. 安装后，当我尝试运行mysql -u root时，它会引发以下错误

after this I installed mysql using homebrew using command brew install mysql. After installation when I tried to run mysql -u root It throws the following error

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

我没有为mysql设置密码.我不知道出了什么问题.任何建议都将不胜感激.谢谢

I didn't set password for mysql.I don't know what's going wrong.Any suggestion will be appreciated. Thank you

推荐答案

我用homebrew安装了mysql，并遇到了与您相同的问题，因为mysql已有一个具有现有密码的现有数据库.有关更多详细信息，请参见本文.

I installed mysql with homebrew and got the same problem as you because mysql has had an existing database with an existing password there. See this article for more details.

$ brew services stop mysql
$ pkill mysqld
$ rm -rf /usr/local/var/mysql/ # NOTE: this will delete your existing database!!!
$ brew postinstall mysql
$ brew services restart mysql
$ mysql -uroot
