Question

我已经设置了一个测试云服务器（Rackspace上的Ubuntu 10.10）来与Cassandra database（0.6.8）一起玩。我可以使用cassandra-cli基本客户端从服务器内部和云外部计算机连接：我创建并检索了样本数据。

然后我在云服务器和外部计算机上安装了phpcassa。

我创建了一个非常简单的php程序来测试连接：

<?php
$GLOBALS['THRIFT_ROOT'] = dirname(__FILE__) . '/include/thrift/';
require_once $GLOBALS['THRIFT_ROOT'].'/packages/cassandra/Cassandra.php';
require_once $GLOBALS['THRIFT_ROOT'].'/transport/TSocket.php';
require_once $GLOBALS['THRIFT_ROOT'].'/protocol/TBinaryProtocol.php';
require_once $GLOBALS['THRIFT_ROOT'].'/transport/TFramedTransport.php';
require_once $GLOBALS['THRIFT_ROOT'].'/transport/TBufferedTransport.php';

include_once(dirname(__FILE__) . '/include/phpcassa.php');
include_once(dirname(__FILE__) . '/include/uuid.php');

echo 'phpcassa test01<br /><br />';
CassandraConn::add_node('184.106.97.245', 9160);

$users = new CassandraCF('Keyspace1', 'Standard2');

try {
    $res = $users->get('jsmith');
    print_r($res);
} catch (Exception $e) {
    print CassandraConn::$last_error;
}

echo 'End.'
?>

我正在使用缓冲传输。

我可以愉快地连接和读取服务器内的数据（我还在其上安装了LAMP）：

phpcassa test01
Array ( [age] => 42 [first] => John [last] => Smith ) 
End.

但不是来自外部，因为我总是得到例外：

phpcassa test01
TException: TSocket: Could not connect to 184.106.97.245:9160 (Operation timed out [60])
End.

这是我的storage-conf.xml文件：

Rackspace支持建议更改防火墙设置，但我没有防火墙：

root@Oahu:~# iptables --list
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         
Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         
Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

非常感谢任何帮助!!!

干杯，鲁杰罗
