ixwebhosting主机提示找不到数据库是什么原因呀？呀

页面提示：
Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

数据库配置：

    'DB_TYPE' => 'mysql',
    'DB_HOST' => 'mysql1209.ixwebhosting.com',
    'DB_NAME' => 'C348703_macroledlight',
    'DB_USER' => 'C348703_miayi',
    'DB_PWD' => 'adwe1523',
    'DB_PORT' => '3306',
    'DB_PREFIX' => 'think_',

这究竟是肿么啦咧，ixwebhosting主机不支持thinkphp吗？
