OTRS can be installed on many different operating systems. OTRS can run on linux and on other unix derivates (e.g. OpenBSD or FreeBSD). You can also deploy it on Microsoft Windows. OTRS does not have excessive hardware requirements. We recommend using a machine with at least a 2 GHz Xeon or comparable CPU, 2 GB RAM and a 160 GB hard drive for a small setup.
To run OTRS you'll also need to use a web server and a database server. Apart from that, on the OTRS machine, you should install perl and/or install some additional perl modules. The web server and Perl have to be installed on the same machine as OTRS. The database back-end can be installed locally or on another host.
For the web server we recommend using the Apache HTTP Server, because its module mod_perl improves greatly the performance of OTRS. Apart from that, OTRS should run on any web server that can execute Perl scripts.
You can deploy OTRS on different databases. You can choose between MySQL, PostgreSQL, Oracle, or Microsoft SQL Server. If you use MySQL you have the advantage that the database and some system settings can be configured during the installation, through a web front-end.
Für Perl gilt mindestens die Version 5.8.8 zu verwenden. Es werden einige Zusatzmodule benötigt, die Sie entweder direkt über die Shell von Perl und CPAN oder mit Hilfe des Paketmanagers (yast, apt-get) Ihres Betriebssystems einspielen müssen.
Software-Anforderungen
Apache2 und mod_perl2 (mod_perl2 wird wegen der hohen Geschwindigkeit empfohlen)
Webserver mit CGI support (CGI nicht empfohlen)
Microsoft Internet Information Server (IIS) 6 or higher
MySQL 4.1 oder höher
PostgreSQL 7.0 or higher (8.2 or higher recommended)
Oracle 10g oder höher
Microsoft SQL Server 2005 or higher
The section in the manual about installation of Perl modules describes in more detail how you can set up those which are needed for OTRS.
Wenn Sie ein bereits vorgefertigtes OTRS-Paket für Ihr Betriebssystem zur Installation verwenden (rpm, Windows-Installer), sollten die benötigten Perl-Module automatisch installiert werden.
For the Agent interface of OTRS, you'll be OK if you use a modern browser with JavaScript support enabled. We support the following browsers:
Internet Explorer 8.0 or higher
Mozilla Firefox 3.6 or higher
Google Chrome
Opera 10 or higher
Safari 4 or higher
We recommend to always use the latest version of your browser, because it has the best JavaScript and rendering performance. Dramatical performance varieties between the used browsers can occur with big data or big systems. We are happy to consult you on that matter.
For the OTRS Customer Interface, in addition to the browsers listed above, you can also use Internet Explorer versions 6 or 7, and we do not require JavaScript either.
