Question

我已经通过composer安装了mongodb php库，但是我遇到了一个与权限有关的问题。有没有办法看看它是否正在运行（我认为它是，因为我显然有一个开放的连接），如果是这样，我将如何为此启用权限？

以下是代码：

    $client = new \MongoDB\Client("mongodb://localhost:27017");

    $collection = $client->test->foo;

    $result = $collection->insertOne(['name' => 'foo', 'sex' => 'Male']);


    $find = $collection->find(['name' => 'foo']);

    foreach ($find as $entry) {
        echo $entry['_id'] . ' : ' . $entry['name'] . ' : ' . $entry['sex'];
    }

我收到的异常消息是：

    MongoDB\Driver\Exception\ConnectionTimeoutException: No suitable servers 
    found (`serverselectiontryonce` set): 
    [Failed connecting to 'localhost:27017': Permission denied]

谢谢！

如果有人需要更多信息，请告诉我。

更新

我在系统shell上运行了命令mongo，这就是出现的结果：

MongoDB shell version: 2.6.11
connecting to: test
2016-06-15T06:59:58.752-0400 warning: Failed to connect to 127.0.0.1:27017, reason: errno:111 Connection refused
2016-06-15T06:59:58.753-0400 Error: couldn't connect to server 127.0.0.1:27017 (127.0.0.1), connection failed at src/mongo/shell/mongo.js:146
exception: connect failed

我有这个错误。我不得不重新启动mongodb来完成这项工作。

我使用了以下命令

// REGULAR FUNCTION

function editTemplates() {

    console.log(this)    // window
    var myVar = this;

    // sits within for loop

    clocksTemplate.gmt[i].addEventListener('keydown', function(e) {

        // new value assigned for 'this' as element bound to clocksTemplate.gmt

        console.log(this);    // returns element bound to clocksTemplate.gmt

        console.log(myVar);    // returns window
    });



// ARROW FUNCTION (Anonymous Functions)

function editTemplates() {

    console.log(this)    // returns window object
    var myVar = this;

    // sits within for loop

    clocksTemplate.gmt[i].addEventListener('keydown', (e) => {

        // No new value gets assigned to 'this'

        console.log(this); // returns window object

        console.log(myVar);    // returns window object

        // Saves the hassle of saving 'this' to another variable!
    });

MongoDB连接超时 - 权限被拒绝
