Question

使用PHP mongodb扩展名尝试连接到需要SSL / TLS的MongoDB服务器时遇到问题：

PHP Fatal error:  Uncaught MongoDB\Driver\Exception\ConnectionTimeoutException: No suitable servers found (`serverSelectionTryOnce` set): [Failed to receive length header from server. calling ismaster on 'mongodb.example.com:27017'] in /tmp/mongodb-test/vendor/mongodb/mongodb/src/Client.php:228

我在线上经历了数十个类似的问题，而且似乎存在连接问题时，这实际上是扩展中的一般错误。到目前为止，我已经尝试了这些常见的解决方案，但没有一个对我有用：

使用IPv4地址代替主机名（通常在MongoDB在本地运行时发生，当在MongoDB配置中未启用IPv6时，localhost被解析为::1时发生）。我也曾尝试将IPv4地址放在我的/ etc / hosts中，也没有帮助。
setsebool -P httpd_can_network_connect on。由SELinux引起，我没有使用。
将net.ssl.allowConnectionsWithoutCertificates设置为false。它似乎无关紧要，但是我还是对其进行了测试，没有帮助。

我正在使用连接字符串，只是为了使事情变得更加奇怪，相同的连接字符串与mongo Shell，Compass和pymongo在同一台机器上以及PHP 7.3 w / mongodb 1.5完美配合。在macOS下为5 。

以下是一些详细信息：

我在Arch Linux下将PHP 7.3.7与mongodb 1.5.5结合使用（我也已经在Ubuntu下进行了测试，具有相同的症状）。

$ php --version

服务器是MongoDB 4.0.10，这是其/etc/mongodb.conf：

---
net:
  bindIpAll: true
  ipv6: true
  ssl:
    PEMKeyFile: /etc/ssl/mongodb.pem    # Let's Encrypt certificate
    mode: requireSSL
security:
  authorization: "enabled"
storage:
  dbPath: /var/lib/mongodb
systemLog:
  destination: file
  logAppend: true
  path: /var/log/mongodb/mongod.log
  quiet: false

当我运行以下脚本时

require 'vendor/autoload.php';

// I've also tried copying the URI parameters to the second argument, didn't work
// allow_invalid_hostname and weak_cert_validation didn't help, either
$client = new MongoDB\Client(
    'mongodb://frederick:password@mongodb.example.com/?ssl=true&authSource=admin'
);
var_dump( $client->listDatabases() );

...失败，并显示（完整日志here，它太长，导致该帖子超出了长度限制）

因此，它似乎设法连接到服务器，但由于某种原因errno: 11 Resource temporarily unavailable失败。而且，如果我禁用SSL / TLS，则无需任何进一步更改即可立即解决此问题。

我现在真的很笨，所以请给我一些启示...谢谢。

使用PHP MongoDB扩展通过SSL / TLS连接时出现问题：ConnectionTimeoutException：找不到合适的服务器（设置了“ serverSelectionTryOnce”）
