MySQL multiple instance into DB Error Error 2002

I did a MySQL multi-instance experiment today,

Enter 3307 no problem.

Enter 3306 : Enter : mysql-s/data/3306/mysql.sock error :

ERROR 2002 (HY000): Can ' t connect to local MySQL server

Solve:

1.

Kill 33934

Kill 34228

2,

I removed the password from the startup script MySQL.

I put the startup script MySQL all chmod +x processing (before 700)

3, restart

Mysqld_safe--defaults-file=/data/3306/my.cnf 2>&1/dev/null &

Login :

Enter : Mysql-s/data/3306/mysql.sock it's normal. .
