无法从PHP连接到MySQL：“mysql_connect（）：没有这样的文件或目录”

我无法通过php连接到mysql。它在PHP中执行mysql_connect()函数时，会在apache错误日志中产生[error] [client 127.0.0.1] PHP Warning: mysql_connect(): No such file or directory错误消息。无法从PHP连接到MySQL：“mysql_connect（）：没有这样的文件或目录”

@heapzero - 这可能是更好的问堆栈溢出。我正在投票决定将其迁移到那里，请不要转贴，如果其他人同意迁移，应该转移。 – JNK 2010-09-15 12:54:51

这是什么确切的平台？你是如何安装MySQL的？ '$ mysqladmin -h \'主机名\'--port = 3306版本'在我的Snow Leopard上可以正常工作，但我看起来MySQL的版本低于你（5.0.51），尽管我最近OSX（10.6.4）。 – 2010-09-15 15:50:46
