[CentOS] Re-configuring BIND DNS Servers for CentOS Web Panel Web Hosting Control Panel on Amazon AWS Cloud
Subject: Re-configuring BIND DNS Servers for CentOS Web Panel Web
Hosting Control Panel on Amazon AWS Cloud
Author: Mr. Turritopsis Dohrnii Teo En Ming, Singapore
Date: 27 Feb 2020 Thursday
Rationale for Re-configuration of BIND DNS Servers for CentOS Web Panel
======================================================================
I have originally followed the approach for cPanel where there are 2
DNS-ONLY servers and one or more cPanel webservers. However, CentOS
Web Panel
implements DNS Clusters differently. Hence I have to re-configure BIND
DNS Servers for CentOS Web Panel web hosting control panel.

Guide: Slave DNS Server & Manager download version
Link: https://wiki.centos-webpanel.com/slave-dns-server-manager-download-version
Login to the CentOS Web Panel Admin Panel on the Slave.
>From the left menu, click on CWP Settings, then select Edit Settings.
Admin Email: ceo at teo-en-ming-corp.com
Check Activate NAT-ed network configuration.
Click Save Changes.
Create a New Account on the Secondary/Slave DNS Server
=====================================================>From the left menu, click User Accounts, then click New Account.
Domain name: teo-en-ming.com
Username: slave
Package: default
Click Create.
Download Slave DNS Manager and upload it to public_html folder on the
Secondary/Slave DNS Server
===============================================================================================
ssh -i cwp.pem centos at 3.12.224.179
su -
cd /home/slave/public_html
wget http://dl1.centos-webpanel.com/files/cwp/addons/cwp-slave_dns.zip
unzip cwp-slave_dns.zip
mv slave_dns/* .
rm -f index.html
Fix file permissions on the Slave DNS Server
===========================================
chown -R slave.slave /home/slave/public_html/*
MySQL: Create User and Database on the Slave DNS Server
======================================================>From the left menu, click SQL Services, then click MySQL Manager.
Click Create Database and User.
New Database for user: slave
Database Name: slave
Click Create Database.
Edit file /home/slave/public_html/inc/db_conn.php.sample and enter
your database connection details
# nano /home/slave/public_html/inc/db_conn.php.sample
# mv inc/db_conn.php.sample inc/db_conn.php
# mysql slave_slave < sql/slave_dns.sql
# nano /etc/sudoers.d/slave

# touch /etc/named/slave.conf
# chmod 771 /etc/named
# usermod -a -G named slave
# chown slave.named /etc/named/slave.conf
# mkdir /var/named/slave
# chown named.named /var/named/slave
Edit File: /etc/named.conf and add this in options section before closing }
masterfile-format text;
Add after options{} where other include lines are specifed
//Slave dns configuration
include "/etc/named/slave.conf";
Now you can login to Slave DNS Manager GUI by using a domain link of
the account you have created.
Go to http://3.12.224.179/~slave/index.php?login
Default login for Slave DNS Manager GUI admin/root
Username: root
Password: FX8QKxvQ
* Please change the default password after the first login
Adding WebServers to Slave DNS Manager
=====================================
- On Slave DNS manager GUI create a new user for each server or use a
single for all webservers if you plan to transfer accounts from one to
another webserver.
Click Add New User.
Username:
Password:
Email:
API Key:
API Secret:
Domain Limit: 1000000
Click Save.
- On Master CentOS Web Panel WebServer go to DNS Functions -> Slave DNS
Manager
Buy CWPPro license first. It is only USD$1.49 compared to USD$20 for
the license of cPanel. I can't afford to buy the license for cPanel,
hence
I have to settle for CentOS Web Panel.
Then ssh into your Master CentOS Web Panel Webserver.
# sh /scripts/update_cwp
You have successfully upgraded to CWPpro.
On the Master CentOS Web Panel, Go to DNS Functions -> Slave DNS Manager
API Key:
Secret Key:
Base URL: http://3.12.224.179/~slave
Master Server IP's: 3.21.30.127
Click Submit.
Master CentOS Web Panel WebServer configuration
==============================================
Edit File: /etc/named.conf and add this in options section before closing }
//Slave dns configuration
allow-transfer {3.12.224.179;};
allow-recursion {3.12.224.179;};
also-notify {3.12.224.179;};
masterfile-format text;
# named-checkconf
# systemctl restart named

I see he?s posted twice already with a different gmail address and one of his own domains. I suspect he?ll keep creating sock puppet email addresses and posting these ?guides? until he grows bored and moves on. Also, the CentOS Web Panel isn?t at all associated with the CentOS project as far as I can tell and just uses the confusion to make people think it?s trustworthy. -- Jonathan Billings <billings at negate.org>
