错误2002（HY000）：无法通过套接字'/var/mysql/mysql.sock'连接到本地MySQL服务器 - 丢失文件

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。自从重新启动计算机后，它就没有运行。我跑ps -u mysql证实这一点，它在我的php.ini装回UID PID TTY TIME CMD错误2002（HY000）：无法通过套接字'/var/mysql/mysql.sock'连接到本地MySQL服务器 - 丢失文件

文件我的socket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文件我的插座

是跌

# These are commonly set, remove the # and set as required. 
# basedir = ..... 
# datadir = ..... 
# port = ..... 
# server_id = ..... 
# socket = .....

在我的自制安装\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？是否创建了一个mysql.sock文件（我不知道该怎么做），然后在php.ini和my.cnf文件中填入空白或未注释的套接字引用？

关于无法在S/O上连接到MYSQL的问题有很多。他们中的许多人从未回答过。我已经看过很多人尝试自己解决这个问题，并且没有提供足够的（希望相关的）信息给比我更聪明的人来尝试修复它。希望它是可以修复的，其他人将从这个问题中受益。

更新

我已经更新了我的插座都php.ini并my.cnf中为/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我得到Can't connect to local MySQL server through socket '/var/mysql/mysql.sock

这是我的日志：

你有这个文件？

/tmp/mysql.sock

如果是的话，尝试在你的php.ini

mysql.default_socket = /tmp/mysql.sock

添加此并重新启动Apache

sudo apachectl restart

否则你有问题，你应该尝试重新启动您的mysqld服务：

launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

我似乎没有该文件。我的/ usr/local /文件夹中没有tmp文件夹 – Jonnny

我运行了'mysql_config --socket'，它用'/ tmp/mysql.sock'返回。所以我更新了我的'php.ini'文件。重新启动Apache。我运行了最后一条命令，它表示操作已在进行中。 – Jonnny
