【问题描述】：

如问题标题中所述，我无法使用 Homebrew 安装 mysql。

shubhamgoyal$ brew install mysql

==> 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

You can try again using `brew postinstall mysql`

shubhamgoyal$ mysql.server 启动

Starting MySQL
. ERROR! The server quit without updating PID file (/usr/local/var/mysql/27-43.priv23.nus.edu.sg.pid).`

我找不到任何 /etc/my.cnf 文件，所以我不知道为什么会出现这个问题。

【解决方案1】：

sudo chown -R $(whoami) /usr/local

【解决方案2】：

如果您使用的是 High Sierra 或更高版本，则无法再对 /usr/local 进行 chown'd。假设您已经使用 Homebrew 安装了 mysql，请尝试：

sudo chown -R $(whoami) $(brew --prefix)/*
