Finally the last part.. Wheww

Apache2 With PHP, Ruby, Python, WebDAV
Now we install Apache with PHP5 (this is PHP 5.2.9):
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
Then edit /etc/httpd/conf/httpd.conf:
vi /etc/httpd/conf/httpd.conf
and change DirectoryIndex to
DirectoryIndex index.html index.htm index.shtml index.cgi index.php index.php3 index.pl
[...]
Now configure your system to start Apache at boot time:
chkconfig --levels 235 httpd on
Start Apache:
/etc/init.d/httpd start
Disable PHP Globally

(If you do not plan to install ISPConfig on this server, please skip this section!)
In ISPConfig you will configure PHP on a per-website basis, i.e. you can specify which website can run PHP scripts and which one cannot. This can only work if PHP is disabled globally because otherwise all websites would be able to run PHP scripts, no matter what you specify in ISPConfig.
To disable PHP globally, we edit /etc/httpd/conf.d/php.conf and comment out the AddHandler and AddType lines:
vi /etc/httpd/conf.d/php.conf
Afterwards we restart Apache:
/etc/init.d/httpd restart

Ruby

Starting with version 2.2.20, ISPConfig has built-in support for Ruby. Instead of using CGI/FastCGI, ISPConfig depends on mod_ruby being available in the server's Apache.
For Fedora 11, there's no mod_ruby package available, so we must compile it ourselves. First we install some prerequisites:
yum install httpd-devel ruby ruby-devel
Next we download and install mod_ruby as follows:
cd /tmp
wget http://www.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
Finally we must add the mod_ruby module to the Apache configuration, so we create the file /etc/httpd/conf.d/ruby.conf...
vi /etc/httpd/conf.d/ruby.conf
And restart Apache.

/etc/init.d/httpd restart
Installing mod_python
To install mod_python, we simply run...
yum install mod_python
... and restart Apache afterwards:
/etc/init.d/httpd restart
ISPConfig

The configuration of the server is now finished. You can now install ISPConfig on it, following these instructions: http://www.ispconfig.org/manual_installation.htm
Before you install ISPConfig, there's one important thing you must do. Open /usr/include/stdio.h and replace getline with parseline in line 653:
vi /usr/include/stdio.h
If you don't do this, the installation will fail because of the following error:
htpasswd.c:101: error: conflicting types for âgetlineâ
/usr/include/stdio.h:653: note: previous declaration of âgetlineâ was here
make[2]: *** [htpasswd.o] Error 1
make[2]: Leaving directory `/home/install_ispconfig/compile_aps/apache_1.3.41/src/support'
make[1]: *** [build-support] Error 1
make[1]: Leaving directory `/home/install_ispconfig/compile_aps/apache_1.3.41'
make: *** [build] Error 2
ERROR: Could not make Apache
You can undo the change to /usr/include/stdio.h after the successful ISPConfig installation (but don't forget to change it back whenever you want to update ISPConfig!).

A Note On SuExec

If you want to run CGI scripts under suExec, you should specify /var/www as the web root for websites created by ISPConfig as Fedora's suExec is compiled with /var/www as Doc_Root. Run
/usr/sbin/suexec -V
and the output should look like this:
[root@server1 ~]# /usr/sbin/suexec -V
-D AP_DOC_ROOT="/var/www"
-D AP_GID_MIN=100
-D AP_HTTPD_USER="apache"
-D AP_LOG_EXEC="/var/log/httpd/suexec.log"
-D AP_SAFE_PATH="/usr/local/bin:/usr/bin:/bin"
-D AP_UID_MIN=500
-D AP_USERDIR_SUFFIX="public_html"
[root@server1 ~]#
So if you want to use suExec with ISPconfig, don't change the default web root (which is /var/www) if you use expert mode during the ISPConfig installation (in standard mode you can't change the web root anyway so you'll be able to use suExec in any case).


Everything should be done now.
Enjoy!
