Multiserver Setup With Dedicated Web, Email, DNS & MySQL Database Servers On Debian Squeeze With ISPConfig 3 - Page 4

5 Installing The Primary DNS Server

Edit the hosts file and add the IP addresses and hostnames for all servers. The hostnames and IP addresses have to be adjusted to match your setup.

vi /etc/hosts

127.0.0.1       localhost
192.168.0.105   web.example.tld
192.168.0.106   mail.example.tld
192.168.0.107   db.example.tld
192.168.0.108   ns1.example.tld
192.168.0.109   ns2.example.tld
 
# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

Set the hostname of the server:

echo ns1.example.tld > /etc/hostname
/etc/init.d/hostname.sh start

Run...

 apt-get update

... to update the apt package database; then run...

apt-get upgrade

... to install the latest updates (if there are any).

It is a good idea to synchronize the system clock with an NTP (network time protocol) server over the Internet. Simply run...

apt-get -y install ntp ntpdate

... and your system time will always be in sync.

Install MySQL client and server:

apt-get -y install mysql-client mysql-server

Enter the new password for MySQL when requested by the installer.

Then install install the commandline version of PHP to be able to run PHP-based shell scripts for ISPConfig:

apt-get -y install php5-cli php5-mysql    php5-mcrypt mcrypt 

Install fail2ban: This is optional but recommended, because the ISPConfig monitor tries to show the log:

apt-get install fail2ban

Install BIND DNS Server:

apt-get -y install bind9 dnsutils

Next install ISPConfig 3 on the dns server. To get the download URL of the latest ISPConfig 3 stable release, please visit the ISPConfig website: http://www.ispconfig.org/ispconfig-3/download/
