1.Mysql 已经装好了，DB driver 也已经安装成功，在尝试连接数据库时候失败

ERROR 2002 (HY000)Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

已经尝试：

mysql start

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

mysql -uroot

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

mysql -h localhost

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

mysql -h 127.0.0.1

ERROR 2003 (HY000): Can't connect to MySQL server on '127.0.0.1' (61)
然后去temp文件夹下面根本没有目标文件

/tmp/mysql.sock

使用查找命令：

find / -name mysql.sock

都是：

Permission denied

网上找了好多都失败～求助，谢谢
