Installing the OS

First obtain a disk image from the Centos 5

Boot from the CD and begin setup. This guide will use the text installer started with arguments linux text

• Skip media test
• OK to welcome screen
• OK to English
• OK to us keyboard layout
• Partition disk(s), for the most part it will be
  • /boot with 100MB
  • swap with 1024MB
  • / with remainder of disk (also enable force to be primary partition)
• OK to use GRUB
• OK - no kernel options needed
• OK leaving no GRUB password
• OK to use default boot loader configuration
• Use /dev/sda or /dev/hda to use the MBR part of the disk for the boot loader
• Default ethernet device settings are DHCP
• OK for system to use UTC and New York time zone
• Root password - make it good!
• Deselect Desktop - Gnome and select Server (NOT GUI!)

Obtaining the package and installing it

Starting with root...

yum -y install yum-priorities
wget http://apt.sw.be/redhat/el5/en/i386/RPMS.dag/rpmforge-release-0.3.6-1.el...
rpm --import http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt
rpm -K rpmforge-release-0.3.6-1.el5.rf.*.rpm
rpm -i rpmforge-release-0.3.6-1.el5.rf.*.rpm
yum -y install gcc gcc-c++ pcre-devel libpng-devel openssl-devel openldap-devel fping rrdtool-devel
yum -y update
echo "all done with yum"

Now reboot with that new Kernel!

Once you've rebooted we've got to get to configuring. Let's start by changing the ServerTokens directive in httpd.conf

nano /etc/httpd/conf/httpd.conf

Change ServerTokens OS to ServerTokens Major

echo "helo" > /var/www/html/index.html
ln -s /etc/init.d/httpd /etc/rc3.d/S83httpd
/etc/init.d/httpd start
useradd HOBBITUSER
passwd HOBBITUSER
chmod o+rx /usr/sbin/fping
chmod o+rx /home/HOBBITUSER
yum check-update
su - HOBBITUSER
cd ~
wget http://internap.dl.sourceforge.net/sourceforge/hobbitmon/hobbit-4.2.0.ta...
tar -xzf hobbit*tar.gz
cd hobbit*

Now compiling Hobbit...

./configure.server

I found fping in /usr/sbin/fping
Do you want to use it [Y/n] ?
y

Do you want to be able to test SSL-enabled services (y) ?
y

Do you want to be able to test LDAP servers (y) ?
y
Enable experimental support for LDAP/SSL (OpenLDAP 2.x only) (y) ?
y

What userid will be running Hobbit [hobbit] ?
HOBBITUSER

At this point accept the defaults until you see...

What group-ID does your webserver use ?
apache

The rest will use default except the name of the host and IP address. These two options will vary depending on the host's destined network installation. Now compile the code:

make

Now exit out to become root and finish with...

cd /home/HOBBITUSER/hobbit*
make install

For the client:

Groundwork Configuration

Let's stop those crawlers at the door!

echo -e User-agent: *"\n"Disallow: / > /var/www/html/robots.txt
echo -e User-agent: *"\n"Disallow: / > ~HOBBITUSER/server/www/robots.txt

You will need to take the configuration from the Hobbit created hobbit-apache.conf and place it in the Apache HTTPD running configuration.

cp /etc/httpd/conf/httpd.conf /etc/httpd/conf/httpd.conf.orig
cat /home/HOBBITUSER/server/etc/hobbit-apache.conf >> /etc/httpd/conf/httpd.conf

and also add some more configuration to httpd.conf

RedirectMatch ^/$ /hobbit/
RedirectMatch ^/robots.txt$ /hobbit/robots.txt

Now test the new httpd.conf and restart Apache HTTPD to those configurations.

apachectl configtest
apachectl graceful

Create a user for the administrative scripts on Hobbit and we're done working with Apache.

htpasswd -c /home/HOBBITUSER/server/etc/hobbitpasswd YOURUSERNAME

Next we'll want to steal the Hobbit startup script and use it to start Hobbit upon entering run level 3.

scp root@essex.imaginenetworksllc.com:/etc/init.d/hobbit /etc/init.d/hobbit
ln -s /etc/init.d/hobbit /etc/rc3.d/S84hobbit

You will need NTP for a time based application =)

yum -y install ntp
cd /etc/rc3.d/
ln -s /etc/init.d/ntpd S11ntpd
ntpdate time.iam8up.com
/etc/init.d/ntpd start
clock -w

Make it so that Hobbit has the capability of reading /var/log/messages

chgrp HOBBITUSER /var/log/messages
chmod g+r /var/log/messages

Hobbit specific configuration

~HOBBITUSER/server/etc/bb-hosts
