Mac用brew安裝 mysql 報錯
MacBook-Pro:mysql apple$ brew postinstall mysql

保證 --datadir目錄爲空。。 /usr/local/var/mysql 這個目錄
我刪除目錄的內容 還是會自動生成，刪除了這mysql然後馬上執行brew postinstall mysql
然後奇蹟出現了
MacBook-Pro:mysql apple$ brew postinstall mysql
==> /usr/local/Cellar/mysql/5.7.12/bin/mysqld --initialize-insecure --user=apple --basedir=/usr/local/Cellar/mysql/5.7.1
MacBook-Pro:mysql apple$ mysql.server start
Starting MySQL
SUCCESS!
服務器也啓動好了
自動生成原因可能是mysqld這個服務器已經啓動。下次遇到可以試試 看活動監視器裏有沒有mysqld這個進程，有就Kill掉
