Create the necessarydirectories under /var/lib :

mkdir -p /var/lib/named/etc
mkdir /var/lib/named/dev
mkdir -p /var/lib/named/var/cache/bind
mkdir /var/lib/named/var/run

Then move the configdirectory from /etc to /var/lib/named/etc :

mv /etc/bind /var/lib/named/etc

Create a symlinkto the new config directory from the old location (to avoid problems when bindis upgraded in the future):

ln -s /var/lib/named/etc/bind/etc/bind

Make null and randomdevices, and fix permissions of the directories:

mknod /var/lib/named/dev/nullc 1 3
mknod /var/lib/named/dev/random c 1 8
chmod 666 /var/lib/named/dev/null /var/lib/named/dev/random
chown -R nobody:nogroup /var/lib/named/var/*
chown -R nobody:nogroup /var/lib/named/etc/bind

We need to modifythe startup script /etc/init.d/sysklogd of sysklogd so that wecan still get important messages logged to the system logs. Modify the line: SYSLOGD="" so that it reads:SYSLOGD="-a/var/lib/named/dev/log" :

#! /bin/sh
# /etc/init.d/sysklogd: start the system log daemon.

PATH=/bin:/usr/bin:/sbin:/usr/sbin

pidfile=/var/run/syslogd.pid

/etc/init.d/postfix restart

To see if SMTP-AUTHand TLS work properly now run the following command:

telnetlocalhost 25

After you haveestablished the connection to your postfix mail server type

ehlolocalhost

If you see thelines

250-STARTTLS

and

250-AUTH

everything is fine.

Type

quit

to return to thesystem's shell.

Courier-IMAP/Courier-POP3

If you want touse a POP3/IMAP daemon that has Maildir support (if you do not want to use thetraditional Unix mailbox format) you can install Courier-IMAP and Courier-POP3.Otherwise you can proceed with the Apache configuration.

apt-get install courier-imapcourier-pop

qpopper and UW-IMAPwill then be replaced.

Then configurePostfix to deliver emails to a user's Maildir*:

postconf -e 'home_mailbox=Maildir/'
postconf -e 'mailbox_command ='
/etc/init.d/postfix restart

*Please note:Youdo not have to do this if you intend to use ISPConfigon your system as ISPConfig does the necessary configuration using procmailrecipes. But please go sure to enable Maildir under Management -> Settings ->EMail in the ISPConfig web interface.

Apache

Add

deb http://packages.dotdeb.org ./

to /etc/apt/sources.list and run

apt-getupdate

apt-getinstall apache apache-doc libapache-mod-ssl libapache-mod-ssl-doc
apt-get install libapache-mod-php4php4 php4-cli php4-common php4-curl php4-dev php4-domxml php4-gd php4-gmp php4-imapphp4-ldap php4-mcal php4-mcrypt php4-mhash php4-ming php4-mysql php4-odbc php4-pearphp4-xslt curl libwww-perl imagemagick (1 line!)

Edit /etc/apache/httpd.conf .Under LoadModules add:

LoadModulephp4_module /usr/lib/apache/1.3/libphp4.so
LoadModule ssl_module /usr/lib/apache/1.3/mod_ssl.so

Under Listen add:

Listen80
Listen 443

Under "Addtypeapplication" insert:

AddType application/x-x509-ca-cert .crt
AddType application/x-pkcs7-crl .crl

Before "Section3 :Virtual Hosts" add:

SSLCACertificateFile /etc/apache/ssl.crt/ca-bundle.crt
SSLPassPhraseDialog builtin
SSLSessionCache dbm:/var/run/ssl_scache
SSLSessionCacheTimeout 300
SSLMutex file:/var/run/ssl_mutex
SSLRandomSeed startup builtin
SSLRandomSeed connect builtin

Change

DirectoryIndexindex.html index.htm index.shtml index.cgi

to

DirectoryIndexindex.html index.htm index.shtml index.cgi index.php index.php3 index.pl

Save /etc/apache/httpd.conf and run

/etc/init.d/apacherestart

Proftpd

apt-getinstall proftpd

<- No

For security reasonsyou can add the following lines to /etc/proftpd.conf (thanks to Reinaldo Carvalho; more information can be found here:http://proftpd.linux.co.uk/localsite/Userguide/linked/userguide.html):

DefaultRoot ~
IdentLookups off
ServerIdent on "FTP Server ready."

and restart Proftpd:

/etc/init.d/proftpd restart

Webalizer

apt-getinstall webalizer

<- accept default values

Synchronizethe System Clock

If you want tohave the system clock synchronized with an NTP server you can add the followinglines to /var/spool/cron/crontabs/root (if the file does not exist, create it by running

touch/var/spool/cron/crontabs/root ):

#update time with ntp server
0 3,9,15,21 * * * /usr/sbin/rdate time.nist.gov | logger -t NTP

Then run

chmod600 /var/spool/cron/crontabs/root
/etc/init.d/cronrestart

Install somePerl Modules needed by SpamAssassin (comes with ISPConfig)

Installationusing the Perl Shell

Login to your commandline as root and run the following command to start the Perl shell:

perl -MCPAN -e shell

If you run thePerl shell for the first time you will be asked some questions. In most casesthe default answers are ok.

Please note:Ifyou run a firewall on your system you might have to turn it off while workingon the Perl shell in order for the Perl shell to be able to fetch the neededmodules without a big delay. You can switch it on afterwards.

The big advantageof the Perl shell compared to the two other methods described here is that itcares about dependencies when installing new modules. I.e., if it turns outthat a prerequisite Perl module is missing when you install another module thePerl shell asks you if it should install the prerequisite module for you. Youshould answer that question with "Yes".

Run the followingcommands to install the modules needed by SpamAssassin:

install HTML::Parser
install DB_File
install Net::DNS (when prompted to enable tests, choose no)
install Digest::SHA1
q (to leave the Perl shell)

If a module isalready installed on your system you will get a message similar to this one:

HTML::Parseris up to date.

Successful installationof a module looks like this:

/usr/bin/makeinstall -- OK

Compile a CustomKernel

If you need tocompile a new kernel for some reason (e.g. because you want to use the latestbleeding-edge kernel or need a feature that the standard Debian kernel doesnot offer), you can find more information here:Debian-Kernel-Compile-Howto.

The End

The configurationof the server is now finished, and if you wish you can now install ISPConfigon it.

A Note On SuExec

If you want torun CGI scripts under suExec, you should specify /var/www as the home directory for websites created by ISPConfig as Debian's suExec iscompiled with /var/www as Doc_Root .Run /usr/lib/apache/suexec -V ,and the output should look like this:

To select /var/www as the home directory for websites during the installation of ISPConfig do thefollowing:When you are asked for the installation mode, select the expertmode .

Later during theinstallation you are asked if the default directory /home/www should be the directory where ISPConfig will create websites in. Answer n and enter /var/www asthe home directory for websites.
