Downloading iTop

You can download iTop from SourceForge:

Software requirements

iTop is based on MySQL and PHP, it requires PHP version 5.3.0 or newer and MySQL version 5.0 or newer, plus of-course a web server: Apache, IIS or any web server supporting PHP 5. Graphviz is needed to display the impact analysis graph.

Optional requirements:

  • For LDAP authentication iTop requires the PHP LDAP module. If this PHP module is not present iTop will not support LDAP or Active Directory identification.
  • For strong encryption of passwords inside iTop, the PHP mcrypt module is required.

Installing the Prerequisites on Debian or Ubuntu

To install the required software on Debian / Ubuntu, run the following commands (as root):

  apt-get install apache2
  apt-get install mysql-server
  apt-get install php5 php5-mysql php5-ldap php5-mcrypt php5-cli php5-soap php5-json graphviz

Installing the Prerequisites on Redhat, CentOS or Fedora

To install the required software on Redhat / CentOS / Fedora, run the following commands (as root):

  yum install httpd
  yum install mysql mysql-server
  yum install php php-mysql php-mcrypt php-xml php-cli php-soap php-ldap graphviz

Installing the Prerequisites on Mageia

Installation of the prerequisistes:

urpmi mariadb
urpmi php php-mysql php-mcrypt php-xml php-cli php-soap php-iconv php-mysqli php-ldap
urpmi graphviz

Activation of the services

systemctl enable httpd
systemctl enable mysqld.service

Changing default PHP settings:

perl -pi -e 's/post_max_size = 8M/post_max_size = 32M/' /etc/php.ini
perl -pi -e 's/;suhosin.get.max_value_length.*/suhosin.get.max_value_length = 2048/' /etc/php.d/Z98_suhosin.ini

Starting the services:

systemctl start httpd
systemctl start mysqld.service

Installing the Prerequisites on Windows

ITop Installation on Windows using IIS

Before running iTop on Windows using IIS, you need to setup IIS to run PHP pages.

Installing Fast-GCI for IIS 6

IIS 6 is the version of IIS that comes with Windows XP and Windows Server 2003. The process is quite similar for IIS7 (see the Useful Links & References below)

  1. Download IIS's Fast-CGI installer from: Pick the version (32 or 64-bit) suitable for your system.
  2. Start the installation by launching the .msi installer

Installing and configuring PHP

  1. Download PHP from Select the appropriate version for your system (32 or 64-bit), and pick the Non Thread Safe version. If you don't know between VC6 and VC9, pick the VC6 version.

Select the IIS Fast-CGI interface:

Make sure that you select the “SOAP” extension which is not enabled by default. Also In the “Extras” section, check the “PEAR Install”.

Then register the FastCGI extension for the whole web site:

cd %windir%\system32\inetsrv
cscript fcgiconfig.js -add -section:\"PHP\" -extension:php -path:\"C:\Program Files\PHP\php-cgi.exe\"

Open the Internet Information Service (IIS) Manager (either from the start menu “Administrative Tools/Internet Information Services (IIS) Manager” or right-click on “My Computer” then “Manage” and “Services And Applications/Internet Information Services (IIS) Manager”) and right-click on the “Default Web Site”. Then choose “Properties”.

Then click on the tab “Home directory” and click on the “Configuration…” button:

Check in the “Mappings” tab that there is an entry for the “.php” extension.

If not, press the “Add…” button and fill the form as below (adjust the path to the correct location of fcgiext.dll)

Go back to the “Documents” tab and check that “index.php” is present, at the top of the list. if it's not there, add an entry for it using the “Add…” button.

Installing MySQL

If you do not already have a MySQL database server, you can install it on the same system as the rest of the application.

  1. Go to MySQL's download site:
  2. Download the installer suitable for your system: select package named “MSI Installer” either the 32 or 64-bit version.
  3. Launch the installation, by opening the downloaded .msi file.

Other dependency: graphviz

iTop relies on Graphviz to produce graphical representations of the object's life-cycle as well as the impact analysis graph.

On RedHat, CentOS and Fedora, graphviz is already packaged, so just run:

sudo yum install graphviz

On Debian and Ubuntu:

sudo apt-get install graphviz

On Windows: download Graphviz from the web site and install it.

You will be prompted to supply the exact path to Graphviz during the setup. The expected value is the the full path to the dot executable (named dot.exe on Windows). For example /user/bin/dot on Linux and C:\Program files (x86)\Graphviz 2.68\bin\dot.exe on Windows.
