This short guide demonstrates how to setup Fedora 13 as a LAMP server containing Apache, PHP, Perl, Python, Ruby and MySQL.

yum install httpd
yum install php php-devel php-gd php-imap php-ldap php-mysql php-odbc php-pear php-xml php-xmlrpc php-eaccelerator php-magickwand php-magpierss php-mapserver php-mbstring php-mcrypt php-mhash php-mssql php-shout php-snmp php-soap php-tidy curl curl-devel perl-libwww-perl ImageMagick libxml2 libxml2-devel
yum install mysql mysql-devel mysql-server
yum install httpd-devel ruby ruby-devel
yum install mod_python
yum install mod_perl
yum install perl-HTML-Parser perl-DBI perl-Net-DNS perl-Digest-SHA1 perl-ExtUtils-AutoInstall perl-NetAddr-IP perl-Archive-Tar
/etc/init.d/httpd restart

Now you have got everything installed except for mod_ruby;

cd /tmp
wget http://modruby.net/archive/mod_ruby-1.3.0.tar.gz
tar zxvf mod_ruby-1.3.0.tar.gz
cd mod_ruby-1.3.0/
./configure.rb --with-apr-includes=/usr/include/apr-1
make
make install

/etc/init.d/httpd restart

You have to add mod_ruby by hand in /etc/httpd/conf.d/ruby.conf
By adding

LoadModule ruby_module modules/mod_ruby.so
