【问题描述】：
我刚开始使用 Homebrew，我的 msql 正在运行。但我似乎无法登录。我已经重新启动了我的计算机，现在它没有运行。我跑了ps -u mysql 来确认这一点，它返回了UID PID TTY TIME CMD
在我加载的 php.ini 文件中，我的套接字命令看起来像这样
; Default socket name for local MySQL connects. If empty, uses the built-in
; MySQL defaults.
; http://php.net/mysql.default-socket
mysql.default_socket =
在我的 my.cnf 文件中，我的套接字已关闭
# These are commonly set, remove the # and set as required.
# basedir = .....
# datadir = .....
# port = .....
# server_id = .....
# socket = .....
在我的 homebrew 安装中 \var\mysql\ 我没有 mysql.sock 文件。
所以我想我的问题是我需要什么来解决这个问题？是创建一个mysql.sock文件（我不知道怎么做）然后在php.ini和my.cnf文件中填写空白或未注释的套接字引用的情况吗？
有很多关于无法在 S/O 上连接到 MYSQL 的问题。他们中的许多人从未得到答复。我查看了很多他们尝试自己解决问题的方法，但未能为比我聪明得多的人提供足够的（希望是相关的）信息来尝试解决问题。希望它是可修复的，其他人将从这个问题中受益。
更新
我已将 php.ini 和 my.cnf 中的套接字更新为 /tmp/mysql.sock。当我在我的 usr/local/var/mysql 文件夹中时，我可以看到我生成了一个 PID 文件。如果我运行mysqladmin version，我会得到Can't connect to local MySQL server through socket '/var/mysql/mysql.sock
这些是我的日志：
