所以我有一个更新的macOS-macOS Mojave 10.14.1。我已安装的mysql版本是5.6-很遗憾，我无法升级（试图运行我们的公司应用，并且我们的文件语法停留在5.6中，而不会在5.7中运行）。我使用自制软件安装。
当我运行mysql.server start时-出现以下错误：
Starting MySQL
. ERROR! The server quit without updating PID file
(/usr/local/var/mysql/Cecilles-MacBook-Pro.local.pid).
我读了很多书，这是一个权限问题，所以我去确保用户设置为mysql而不是root或我。

查看mysql.server是否只是一个符号链接-确实是。
➜ support-files which mysql.server
/usr/local/opt/mysql@5.6/bin/mysql.server
所以我去那里更改任何必要的权限。

我运行mysql.server start并且仍然没有骰子。我很确定由于权限问题而没有创建PID文件，但是目前，我还不确定要更改权限/所有者的其他条件。
任何反馈将不胜感激，谢谢！
