11 Apache2 With PHP, Ruby, Python, WebDAV

Now we install Apache with PHP5 (this is PHP 5.3.0):

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

11.1 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:

vvi /etc/httpd/conf.d/php.conf

#
            # PHP is an HTML-embedded scripting language which attempts to make it
            # easy for developers to write dynamically generated webpages.
            #
            <IfModule prefork.c>
            LoadModule php5_module modules/libphp5.so
            </IfModule>
            <IfModule worker.c>
            LoadModule php5_module modules/libphp5-zts.so
            </IfModule>
            #
            # Cause the PHP interpreter to handle files with a .php extension.
            #
            #AddHandler php5-script .php
            #AddType text/html .php
            #
            # Add index.php to the list of files that will be served as directory
            # indexes.
            #
            DirectoryIndex index.php
            #
            # Uncomment the following line to allow PHP to pretty-print .phps
            # files as PHP source code:
            #
            #AddType application/x-httpd-php-source .phps

Afterwards we restart Apache:

/etc/init.d/httpd restart

11.2 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 12, 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./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

LoadModule ruby_module modules/mod_ruby.so

... and restart Apache:

');

/etc/init.d/httpd restart

You can find more details about mod_ruby in this article.

11.3 Installing mod_python

To install mod_python, we simply run...

yum install mod_python

... and restart Apache afterwards:

/etc/init.d/httpd restart

11.4 WebDAV

WebDAV should already be enabled, but to check this, open /etc/httpd/conf/httpd.conf and make sure that the following two modules are active:

vi /etc/httpd/conf/httpd.conf

[...]
            LoadModule dav_module modules/mod_dav.so
            [...]
            LoadModule dav_fs_module modules/mod_dav_fs.so
            [...]

If you have to modify /etc/httpd/conf/httpd.conf, don't forget to restart Apache afterwards:

/etc/init.d/httpd restart

12 ProFTPd

ISPConfig has better support for proftpd than vsftpd, so let's remove vsftpd and install proftpd:

yum remove vsftpd

yum install proftpd

Now we can create the system startup links for Proftpd and start it:

chkconfig --levels 235 proftpd on
/etc/init.d/proftpd start

13 Webalizer

To install webalizer, just run

yum install webalizer

14 Synchronize The System Clock

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

yum install ntp

chkconfig --levels 235 ntpd on
ntpdate 0.pool.ntp.org
/etc/init.d/ntpd start

15 Install Some Perl Modules

ISPConfig comes with SpamAssassin which needs a few Perl modules to work. We install the required Perl modules with a single command:

yum install perl-HTML-Parser perl-DBI perl-Net-DNS perl-Digest-SHA1 perl-ExtUtils-AutoInstall

16 ISPConfig

The configuration of the server is now finished. You can now install ISPConfig on it, following these instructions: http://www./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:

vim /usr/include/stdio.h

[...]
            /* Like `getdelim', but reads up to a newline.
            This function is not part of POSIX and therefore no official
            cancellation point.  But due to similarity with an POSIX interface
            or due to the implementation it is a cancellation point and
            therefore not marked with __THROW.  */
            extern _IO_ssize_t parseline (char **__restrict __lineptr,
            size_t *__restrict __n,
            FILE *__restrict __stream) __wur;
            #endif
            [...]

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!).

16.1 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).
