osx下brew install mysql之后mysql报错的问题
报错如下：
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
然后查看/tmp/目录下根本没有mysql.sock
其实当年安装完brew install mysql之后，还要这样：
brew info mysql来进行配置
用他们推荐的mysql.server start无法启动，报错：
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).
但是突然发现用这种方式可以：
junjiedeMacBook-Pro:mysql junjielin$ mysql -uroot -h127.0.0.1 -p
Enter password:

这是怎么回事？
后来重启电脑之后正常了！

现在mysql没有问题了~~
2016.2.24：
今天有碰到这个问题了，我删除了/usr/local/var/mysql/*.err 的文件，一切就没问题了: ), mysql.server start 成功启动mysql数据库。
