cd /etc/yum.repos.d/
wget http://www.go-mono.com/download-stab...i386/mono.repo

Install mono

yum install mono-complete

Install mysql 5.0.48

As of  23/10/2007 CentOS 5 mysql is < than 5.0.43 and therefore has a bug (please see this thread in the forums)

As suggested by howlym add a new file utterramblings.repo in /etc/yum.repos/

Put below content to this new file:
***********************************
[utterramblings]
name=Jasons Utter Ramblings Repo
baseurl=http://www.jasonlitka.com/media/EL4/$basearch/
enabled=1
gpgcheck=0
gpgkey=http://www.jasonlitka.com/media/RPM-GPG-KEY-jlitka"
**********************************

This will let you upgrade/install your mysql to 5.0.48

yum install httpd mysql-server php php-pear php-mysql php-gd php-curl php-mbstring ImageMagick wv links pdftohtml mysql-client
pear install Cache_Lite

Create /var/www/.wapi for mono

mkdir /var/www/.wapi
chown apache /var/www/.wapi

Edit /etc/php.ini and change the following parameters

memory_limit = 128M
post_max_size = 64M

Change the shell for the apache user. Edit /etc/passwd and change this:

Install Deki Wiki

mkdir /source
cd /source
tar xvzf Deki_Wiki_1.8.2a_Hayes_source.tar.gz
mkdir /var/www/deki-hayes
cd Deki_Wiki_1.8.2a_Hayes_source
cp -r web/* /var/www/deki-hayes/
service httpd restart

Edit the config/dekihost init script.

Change the following values to match your configuration:

# path to your wiki
DEKI_PATH=/var/www/deki-hayes

# this should match your Apache ServerName directive
DEKI_SERVERNAME=dekiwiki.example.com

# Then change the start() and stop() functions so they look like this:

start(){
su apache $DEKI_PATH/bin/mindtouch.host.sh start
}
stop(){
su apache $DEKI_PATH/bin/mindtouch.host.sh stop
}

Autostart dekiwiki

cp config/dekihost /etc/init.d/
ln -s /etc/init.d/dekihost /etc/rc3.d/S86dekihost
ln -s /etc/init.d/dekihost /etc/rc5.d/S86dekihost

Create a log file

touch /var/log/deki-api.log
chown apache /var/log/deki-api.log

Configure Apache to serve up the wiki

Modify /etc/httpd/conf/httpd.conf (or wherever your virtual servers are configured) to include:

NameVirtualHost *:80
#
# NOTE: NameVirtualHost cannot be used without a port specifier
# (e.g. :80) if mod_ssl is being used, due to the nature of the
# SSL protocol.
#

#
# VirtualHost example:
# Almost any Apache directive may go into a VirtualHost container.
# The first VirtualHost section is used for requests without a known
# server name.
#
<VirtualHost *:80>
ServerName dekiwiki.example.com

Post-configuration steps

After the web configuration has finished instead of the proposed course use this slightly modified one:

chown apache /etc/dekiwiki
cp mindtouch.deki.startup.xml /etc/dekiwiki
cp LocalSettings.php /var/www/deki-hayes/

cp mindtouch.host.sh /var/www/deki-hayes/bin/
/etc/init.d/dekihost start
