Hi,
Let me repost the problem.
Hope someone can help me resolve this issue with connecting to MongoDB using PHP via http.
Thanks!
DH
The basic setup:
CentOS 7 (release 7.7.1908)
MongoDB v4.2.5, new installation, no authentication.
PHP version 7.4.5
Driver install via ‘pecl install mongodb’
Seeing this error:
No suitable servers found (serverSelectionTryOnce set): [connection refused calling ismaster on ‘127.0.0.1:27017’]
Is there a solution to this problem that I’m not aware of? Is there some mismatch versions of dependent modules or libraries?
Please see more info below. The driver seems to be installed correctly, since the PHP standalone command works but via HTTP, it does not work. And the var_dump shows MongoDB\Client ok on either way.
Thanks for any help.
Here’s a simple PHP test script:
$ cat testmongo.php
<?php
require_once "vendor/autoload.php";
try {
$mc = new MongoDB\Client('mongodb://127.0.0.1/');
print_r($mc);
$dbs = $mc->listDatabases();
print_r($dbs);
} catch (Exception $e) {
echo $e->getMessage();
}
?>
PROBLEM connecting to the database via HTTP (using curl):
$ curl http://localhost/testmongo.php

(
)
)
No suitable servers found (`serverSelectionTryOnce` set): [connection refused calling ismaster on '127.0.0.1:27017']
But it works in PHP command mode (not sure why or what’s the difference than previous?):
$ php -f testmongo.php
