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

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：

 

# 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

原来mysql用的套接字文件是： /opt/lampp/var/mysql/mysql.sock 于是建立了个软连接， 命令如下。不能建立硬链接，不知道为什么。

 

ln -s /opt/lampp/var/mysql/mysql.sock  /var/run/mysqld/mysqld.sock

现在可以用mysql -uroot命令登陆上了~
