基于php的权威dns解析服务器程序PHP DNS Server

An Authoritative DNS Server written purely in PHP.

This is an Authoritative DNS Server written in pure PHP. It will listen to DNS request on the default port (Default: port 53) and give answers about any domain that it has DNS records for. This class can be used to give DNS responses dynamically based on your pre-existing PHP code.

Requirements

• PHP 7.2+
• Needs either sockets or socket_create PHP extension loaded (which they are by default)

Example

Here is an example of DNS server usage:

require_once __DIR__.'/../vendor/autoload.php';

// JsonResolver created and provided with path to file with json dns records
$jsonResolver = new yswery\DNS\Resolver\JsonResolver([
    '/path/to/zones/example.com.json',
    '/path/to/zone/test.com.json',
]);

// System resolver acting as a fallback to the JsonResolver
$systemResolver = new yswery\DNS\Resolver\SystemResolver();

// StackableResolver will try each resolver in order and return the first match
$stackableResolver = new yswery\DNS\Resolver\StackableResolver([$jsonResolver, $systemResolver]);

// Create the eventDispatcher and add the event subscribers
$eventDispatcher = new \Symfony\Component\EventDispatcher\EventDispatcher();
$eventDispatcher->addSubscriber(new \yswery\DNS\Event\Subscriber\EchoLogger());

// Create a new instance of Server class
$server = new yswery\DNS\Server($stackableResolver, $eventDispatcher);

// Start DNS server
$server->start();

Running example

• Run composer install to install dependencies
• Run php example/example.php to run the server

Query server using dig command to ensure proper functioning

$ dig @127.0.0.1 test.com A +short
111.111.111.111

$ dig @127.0.0.1 test.com TXT +short
"Some text."

$ dig @127.0.0.1 test2.com A +short
111.111.111.111
112.112.112.112

Zone File Storage

PHP DNS Server supports four zone file formats out-of-the-box: Bind, JSON, XML, and YAML; each file format is supported by a specialised Resolver class: BindResolver, JsonResolver, XmlResolver, and YamlResolver, respectively. Example files are in the example/ directory.

JSON zone example

{
  "domain": "example.com.",
  "default-ttl": 7200,
  "resource-records": [
    {
      "name": "@",
      "ttl": 10800,
      "type": "SOA",
      "class": "IN",
      "mname": "example.com.",
      "rname": "postmaster",
      "serial": 2,
      "refresh": 3600,
      "retry": 7200,
      "expire": 10800,
      "minimum": 3600
    }, {
      "type": "A",
      "address": "12.34.56.78"
    },{
      "type": "A",
      "address": "90.12.34.56"
    }, {
      "type": "AAAA",
      "address": "2001:acad:ad::32"
    }, {
      "name": "www",
      "type": "cname",
      "target": "@"
    }, {
      "name": "@",
      "type": "MX",
      "preference": 15,
      "exchange": "mail"
    }, {
      "name": "*.subdomain",
      "ttl": 3600,
      "type": "A",
      "address": "192.168.1.42"
    }
  ]
}

Running Tests

Unit tests using PHPUnit are provided. A simple script is located in the root.

• run composer install to install PHPUnit and dependencies
• run vendor/bin/phpunit from the root to run the tests

Building .phar

• run composer run-script build-server to build the phpdnsserver.phar file, outputs in the bin folder.
• run composer run-script build-console to build the phpdnscli.phar file, outputs in the bin folder.
• run composer run-script build-installer to build the installer. Windows support for the installer is currently limited.

Running the .phar files

To run the new .phar files, download them from the release and move them to the desired folder.

• phpdnsserver.phar to run the phpdnsserver, uses the new filesystem by default
• phpdnscli.phar to run cli commands
• phpdnsinstaller.phar as root to create required folders and default config.

Supported command line switches

• --bind:b - bind to a specific ip. Uses 0.0.0.0 by default
• --port:p - bind to a specific port. Uses port 53 by default
• --config:c - specify the config file. Uses phpdns.json on windows and /etc/phpdns.json on unix systems by default
• --storage:s - specify the path to the storage for zones, and logs. Uses /etc/phpdnsserver on unix, and current working directory on windows.

Supported Record Types

• A
• NS
• CNAME
• SOA
• PTR
• MX
• TXT
• AAAA
• AXFR
• ANY
• SRV
