PHP的FTP不工作在Amazon Linux的EC2实例？ [英] PHP's FTP isn't working on Amazon linux EC2 instance?

问题描述

我成立了一个m1.large EC2实例，并希望用它来下载日志掀起了CDN的服务器。我有code工作就好在我的Ubuntu的笔记本电脑，但一旦上传到ftp_rawlist（）函数停止工作的服务器。至于我可以告诉code仍是登录到FTP服务器，但rawlist没有返回任何文件。

I set up a m1.large EC2 instance and want to use it to download logs off a cdn's server. I had the code working just fine on my ubuntu laptop but once uploaded to the server the ftp_rawlist() function stopped working. As far as i can tell the code is still logging into the ftp server but rawlist isn't returning any files.

下面是示例code：

<?php

$FTP_USERNAME = 'username';
$FTP_PASSWORD = 'pass';
$FTP_SERVER   = 'cdn.server';
$FTP_LOGDIR   = 'logs';

$conn_id = ftp_connect($FTP_SERVER) or die('Couldn\'t connect to '.$FTP_SERVER);

if(!ftp_login($conn_id, $FTP_USERNAME, $FTP_PASSWORD)) {
        die('Couldn\'t connect as '.$FTP_USERNAME);
}

ftp_chdir($conn_id, $FTP_LOGDIR);

$rawlist = ftp_rawlist($conn_id, '.');

ftp_close($conn_id);

var_dump($rawlist);
?>

和输出是这样的：

bool(false)

尽管我知道目录不是空的。

even though i know the directory isn't empty.

在设置服务器，这些都是我用来安装所有的命令：

When setting up the server these are the commands i used to install everything:

sudo yum install php
sudo yum install php-mysql
sudo yum install php-pear
sudo pear channel-discover pear.amazonwebservices.com
sudo pear install aws/sdk

我甚至打开所有的端口安全组，但即使再输出仍然布尔（假）。和PHP -i显示，启用FTP。

I even opened all the ports for the security group but even then the output was still bool(false). And php -i shows that ftp is enabled.

任何帮助将是很大的AP preciated，我一直在货架我的脑子整天都试图弄清楚这一点。

Any help would be greatly appreciated, i have been racking my brain all day trying to figure this out.

推荐答案

所需在被动模式下运行。

Needed to run it in passive mode

ftp_pasv($conn_id, true);
