ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock'解决

用XAMPP装装好mysql之后，mysql -uroot 连不上，报这个错误：

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock'

在mysql的配置文件里，/opt/lampp/etc/my.cnf， 发现了这样的配置：

[java]

# The following options will be passed to all MySQL clients

[client]

#password = your_password

port = 3306

socket = /opt/lampp/var/mysql/mysql.sock

# Here follows entries for some specific programs

# The MySQL server

[mysqld]

user = nobody

port = 3306

socket = /opt/lampp/var/mysql/mysql.sock
