MySQL不喜欢ins〜/ .my.cnf中的任何配置

Question

Mac El Capitan（10.11.6）在这里。 我通过自制软件安装了MySQL（ brew install mysql ，安装了5.7.17 ），并能够使用默认值（对my.cnf绝对为零配置）启动它。 我能够用表创建数据库，填充表等。

我打开~/.my.cnf并看到它为空，这很有意义，因为我一开始从未向它添加任何特殊配置。

所以我添加（到这个空文件）：

[mysqld]
default-storage-engine = innodb
default-character-set=utf8
collation-server = utf8_unicode_ci
init-connect='SET NAMES utf8'

然后我运行mysql.server start启动MySQL并：

mysql.server start
Starting MySQL
... ERROR! The server quit without updating PID file (/usr/local/var/mysql/MyUsername.local.pid).

如果清除~/.my.cnf的内容（并再次使其为空）并重新启动MySQL，它的启动将完全正常（无错误；我可以查询表等）。 但是，如果我重新添加这些内容，则会收到相同的错误。

因此， 很明显， MySQL正在检查~/.my.cnf以加载配置，并且显然 ，它不喜欢这种语法。 因此，我开始了一系列的配置/测试周期，以查看哪个属性是犯罪者。

我将~/.my.cnf更改为：

[mysqld]
default-storage-engine = innodb

并重新启动。 完全相同的错误。

我将~/.my.cnf更改为：

[mysqld]
default-character-set=utf8

并重新启动。 完全相同的错误。

我将~/.my.cnf更改为：

[mysqld]
collation-server = utf8_unicode_ci

并重新启动。 完全相同的错误。

我将~/.my.cnf更改为：

[mysqld]
init-connect='SET NAMES utf8'

并重新启动。 完全相同的错误。 显然，这里还有其他事情。 当我在~/.my.cnf指定任何配置时，MySQL不喜欢它。 这里发生了什么？！？

我试着按照所有建议这篇文章 ，但没有一次成功。 绝对像是MacOS / MySQL问题。

如果我打开/usr/local/var/mysql/MyUser.local.err我会看到：

关于字符集：可能不再允许您编写任何内容。

请参阅my.cnf中的将MySQL默认字符集更改为UTF-8
