1st commit for dns_slave_auto

parent 9cd6f8c8
Author: Florian Schaal, schaal @it
ISPConfig version: 3.1.3
This addon adds dns-slave-zones on additional servers after creating a dns-zone
If you managed multiple servers with ISPConfig but did not use the mirror-function,
you can i.e. use server 1 for bind and server 2 as a bind-slave. This plugin
manages the slave-zones on server 2 when you create / change / delete the
dns-zone on server 1.
Installation
--------------------
Download the addon to your server and run the install.sh script to install it.
Usage
--------------------
Adjust the following settings in /usr/local/ispconfig/interface/lib/plugins/dns_dns_slave_auto_plugin.inc.php
1.
//* define your dns-ip(s) that the slave-server should accept the data from (same as NS (IP-address) in Secondary DNS Zones)
$this->nameservers[] = '192.168.0.1';
$this->nameservers[] = 'fe80::2';
If your master-server has only one IP, remove one one the lines.
2.
//* define the server_ids for slave-server(s) (see server_id in dbispconfig.server on the master)
$this->dns_slave_server_id[] = 2;
If you want to run bind-slave on several servers, use more settings. I.e.
$this->dns_slave_server_id[] = 2;
$this->dns_slave_server_id[] = 12;
$this->dns_slave_server_id[] = 18;
