我刚刚开始使用 Homebrew，并且我的 msql 正在运行。但我似乎无法登录。我重新启动了计算机，但现在它没有运行。我跑了ps -u mysql确认这一点，它返回 UID PID TTY TIME CMD
在我加载的 php.ini 文件中，我的套接字命令如下所示
; 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？是否是创建一个 mysql.sock 文件(我不知道该怎么做)，然后在 php.ini 和 my.cnf 文件中填写对套接字的空白或未注释的引用？
关于无法连接到 S/O 上的 MYSQL 有很多问题。其中许多问题从未得到答复。我查看了其中的很多内容，尝试自己解决问题，但未能向比我聪明得多的人提供足够的(希望相关的)信息来尝试解决问题。希望它是可以修复的，并且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 usr/local/var/mysql 文件夹中时，我可以看到生成了一个 PID 文件。如果我运行 mysqladmin version我得到Can't connect to local MySQL server through socket '/var/mysql/mysql.sock
这些是我的日志:

最佳答案
你有这个文件吗？
/tmp/mysql.sock
如果是这样，请尝试将其添加到您的 php.ini
mysql.default_socket = /tmp/mysql.sock
并重新启动apache
sudo apachectl restart
否则您遇到问题，您应该尝试重新启动 mysqld 服务:
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
