I'm interesting in playing around with NoSQL and particularly MongoDB. To this end, I've installed MongoDB on an external Linux box by SSHing into the server and running the following command:
sudo pecl install mongo
Mongo seems to have installed correctly and there's now a 'Mongo' section if I run phpinfo()
.
But what now? I seem to be having trouble going from here to using it in production. The problem being, I don't think the MongoDB service is running, and I haven't configured any MongoDB users because I'm not sure how to. As a result, the following test script fails:
<?php
// connect
$m = new Mongo();
// select a database
$db = $m->comedy;
// select a collection (analogous to a relational database's table)
$collection = $db->cartoons;
// add a record
$obj = array( "title" => "Calvin and Hobbes", "author" => "Bill Watterson" );
$collection->insert($obj);
// add another record, with a different "shape"
$obj = array( "title" => "XKCD", "online" => true );
$collection->insert($obj);
// find everything in the collection
$cursor = $collection->find();
// iterate through the results
foreach ($cursor as $obj) {
echo $obj["title"] . "\n";
}
?>
As I get the following error message:
Fatal error: Uncaught exception 'MongoConnectionException' with message 'connecting to failed: Transport endpoint is not connected' in /home/[username]/public_html/mongodbtest/index.php:4 Stack trace: #0 /home/[username]/public_html/mongodbtest/index.php(4): Mongo->__construct() #1 {main} thrown in /home/woohoobi/public_html/mongodbtest/index.php on line 4
Ho开发者_如何学Cw can I get from here to using MongoDB?
You never actually installed MongoDB, but rather the PHP extension that lets you connect to a MongoDB instance. Install MongoDB by downloading it and installing it on your server, and then connect to it from your PHP script.
