The Perfect Server - OpenSUSE 11.2 x86_64 [ISPConfig 3] - Page 5

12 MyDNS

We install the MyDNS rpm package for i386 which works on x86_64 as well:

rpm -ivh --force mydns-mysql-1.1.0-1.i386.rpm

Create the following MyDNS init script:

vi /etc/init.d/mydns

# compliant Linux distributions, you either have to provide the rc.status

# Provides:          mydns
# Required-Start:    $syslog $remote_fs
# Should-Start: $time ypbind sendmail

# Short-Description: mydns XYZ daemon providing ZYX
# Description:       Start mydns to allow XY and provide YZ
#       continued on second line by '#<TAB>'
#       should contain enough info for the runlevel editor
#       to give admin some idea what this service does and
#       what it's needed for ...
#       (The Short-Description should already be a good hint.)
# Any extensions to the keywords given above should be preceeded by
# X-VendorTag- (X-UnitedLinux- X-SuSE- for us) according to LSB.
# Notes on Required-Start/Should-Start:
# * There are two different issues that are solved by Required-Start
#    and Should-Start
# (a) Hard dependencies: This is used by the runlevel editor to determine
#     which services absolutely need to be started to make the start of
#     this service make sense. Example: nfsserver should have
#     Required-Start: $portmap
#     Also, required services are started before the dependent ones.
#     The runlevel editor will warn about such missing hard dependencies
#     and suggest enabling. During system startup, you may expect an error,
#     if the dependency is not fulfilled.
# (b) Specifying the init script ordering, not real (hard) dependencies.
#     This is needed by insserv to determine which service should be
#     started first (and at a later stage what services can be started
#     in parallel). The tag Should-Start: is used for this.
#     It tells, that if a service is available, it should be started
#     before. If not, never mind.
# * When specifying hard dependencies or ordering requirements, you can
#   use names of services (contents of their Provides: section)
#   or pseudo names starting with a $. The following ones are available
#   according to LSB (1.1):
#       $local_fs               all local file systems are mounted
#                               (most services should need this!)
#       $remote_fs              all remote file systems are mounted
#                               (note that /usr may be remote, so
#                                many services should Require this!)
#       $syslog                 system logging facility up
#       $network                low level networking (eth card, ...)
#       $named                  hostname resolution available
#       $netdaemons             all network daemons are running
#   The $netdaemons pseudo service has been removed in LSB 1.2.
#   For now, we still offer it for backward compatibility.
#   These are new (LSB 1.2):
#       $time                   the system time has been set correctly
#       $portmap                SunRPC portmapping service available
#   UnitedLinux extensions:
#       $ALL                    indicates that a script should be inserted
#                               at the end
# * The services specified in the stop tags
#   (Required-Stop/Should-Stop)
#   specify which services need to be still running when this service
#   is shut down. Often the entries there are just copies or a subset
#   from the respective start tag.
# * Should-Start/Stop are now part of LSB as of 2.0,
#   formerly SUSE/Unitedlinux used X-UnitedLinux-Should-Start/-Stop.
#   insserv does support both variants.
# * X-UnitedLinux-Default-Enabled: yes/no is used at installation time
#   (%fillup_and_insserv macro in %post of many RPMs) to specify whether
#   a startup script should default to be enabled after installation.
#   It's not used by insserv.
# Note on runlevels:
# 0 - halt/poweroff                     6 - reboot
# 1 - single user                       2 - multiuser without network exported
# 3 - multiuser w/ network (text mode)  5 - multiuser w/ network and X11 (xdm)
# Note on script names:
# A registry has been set up to manage the init script namespace.
# Please use the names already registered or register one or use a
# vendor prefix.

# Check for missing binaries (stale symlinks should not happen)
# Note: Special treatment of stop for LSB conformance

Make the init script executable...

chmod 755 /etc/init.d/mydns

... and create the system startup links for MyDNS:

chkconfig --add mydns


13 Install vlogger and Webalizer

cd /tmp
tar xvfz vlogger-1.3.tar.gz
mv vlogger-1.3/vlogger /usr/sbin/
rm -rf vlogger*
yast2 -i webalizer perl-DateManip


14 Install fail2ban

rpm -i

Warnings like warning: /var/tmp/rpm-xfer.SCm0TM: Header V3 DSA signature: NOKEY, key ID 5b00c76e can be ignored.


15 Install jailkit

cd /tmp
tar xvfz jailkit-2.10.tar.gz
cd jailkit-2.10
make install
cd ..
rm -rf jailkit-2.10*


16 Synchronize the System Clock

If you want to have the system clock synchronized with an NTP server do the following:

yast2 -i xntp

Then add system startup links for ntp and start ntp:

chkconfig --add ntp
/etc/init.d/ntp start


17 ISPConfig 3

Download the current ISPConfig version and install it. The ISPConfig installer will configure all services like postfix, sasl, courier, etc. for you. A manual setup as required for ISPConfig 2 is not necessary anymore.

cd /tmp
tar xvfz ISPConfig-
cd ispconfig3_install/install/

Now start the installation process by executing:

php -q install.php

server1:/tmp/ispconfig3_install/install # php -q install.php

19 Disable AppArmor

AppArmor is a security extension of SUSE (similar to Fedora's SELinux) that should provide extended security. In my opinion you don't need it to configure a secure system, and it usually causes more problems than advantages (think of it after you have done a week of trouble-shooting because some service wasn't working as expected, and then you find out that everything was ok, only AppArmor was causing the problem). Therefore I disable it (this is a must if you want to install ISPConfig later on).

We can disable it like this:

/etc/init.d/boot.apparmor stop
chkconfig -d boot.apparmor
