无法在 Mac 上启动 MySQL - 权限被拒绝

Question

我试图在 Mac (High Sierra) 上运行通过 HomeBrew 安装的 MySQL，但我总是遇到这些权限和 PID 文件问题。我尝试了在网上找到的数百种可能的解决方案，但无法解决这些问题：

Haline:/ Haline$ mysql.server start
Starting MySQL
./usr/local/Cellar/mysql/8.0.12/bin/mysqld_safe: line 144: /usr/local/var/mysql/Haline.local.err: Permission denied
/usr/local/Cellar/mysql/8.0.12/bin/mysqld_safe: line 144: /usr/local/var/mysql/Haline.local.err: Permission denied
/usr/local/Cellar/mysql/8.0.12/bin/mysqld_safe: line 199: /usr/local/var/mysql/Haline.local.err: Permission denied
/usr/local/Cellar/mysql/8.0.12/bin/mysqld_safe: line 144: /usr/local/var/mysql/Haline.local.err: Permission denied
 ERROR! The server quit without updating PID file (/usr/local/var/mysql/Haline.local.pid).

有人可以帮助我吗？

根据Homebrew 的官方故障排除页面：

如果命令因权限错误而失败，请检查 /usr/local\xe2\x80\x99s 子目录的权限。如果您\xe2\x80\x99不确定该怎么做，您可以运行cd /usr/local && sudo chown -R $(whoami) bin etc include lib sbin share var opt Cellar Caskroom Frameworks.

或者，如果您尚未安装/usr/local依赖于特定权限的应用程序，您也可以运行：

sudo chown -R $(whoami) /usr/local/*\n
