osx下brew install mysql之後mysql報錯的問題
報錯如下：
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
然後檢視/tmp/目錄下根本沒有mysql.sock
其實當年安裝完brew install mysql之後，還要這樣：
brew info mysql來進行配置
用他們推薦的mysql.server start無法啟動，報錯：
junjiedeMacBook-Pro:mysql junjielin$ mysql.server start
Starting MySQL
..................................................................................................... ERROR! The server quit without updating PID file (/usr/local/var/mysql/junjiedeMacBook-Pro.local.pid).
但是突然發現用這種方式可以：
junjiedeMacBook-Pro:mysql junjielin$ mysql -uroot -h127.0.0.1 -p
Enter password:

這是怎麼回事？
後來重啟電腦之後正常了！

現在mysql沒有問題了~~
2016.2.24：
今天有碰到這個問題了，我刪除了/usr/local/var/mysql/*.err 的檔案，一切就沒問題了: ), mysql.server start 成功啟動mysql資料庫。
