TWiki System Requirements
Server and client requirements for TWiki 01-Feb-2003
Low client and server requirements are core features that keep TWiki widely deployable, particularly across a range of browser platforms and versions.
Server Requirements
TWiki is written in Perl 5, uses a number of shell commands, and requires
RCS (Revision Control System), a GNU Free Software package. TWiki is developed in a basic Linux/Apache environment. It also works with Microsoft Windows, and should have no problem on any other platform that meets the requirements.
Required Server Environment |
Resource | Unix | Windows* |
Perl | 5.005_03 or higher (5.6.1 recommended, 5.8.0 not recommended yet, see TWiki:Codev.UsingPerl58OnRedHat8) |
Non-standard Perl modules | Net::SMTP (or sendmail ) | Net::SMTP , MIME::Base64 , Digest::SHA1 |
RCS | 5.7 or higher (including GNU diff ) Optional, but the all-Perl RCS replacement is not currently recommended for live sites - see TWiki:Codev.RcsLite. |
GNU diff | GNU diff 2.7 or higher is required when not using the all-Perl RcsLite. Install on PATH if not included with RCS (check version with diff -v ) |
Other external programs | ls, fgrep, egrep |
Cron/scheduler | cron | cron equivalents |
Web server | Apache 1.3 is well supported; Apache 2.0 is not recommended yet (see TWiki:Support.FailedAuthenticationWithApache2OnWinNT). For other servers, CGI support, authentication, extended path required |
* Current documentation mainly covers Linux and Apache installations. See WindowsInstallCookbook for a Windows installation guide. See TWiki:Codev.TWikiOn for help with installation on various platforms including Unix, MacOS X, Apache mod_perl
, web hosts, etc.
Client Requirements
The TWiki
standard installation has extremely low browser requirements:
- HTML 3.2 compliant
- generates XHTML 1.0 pages that are compatible with HTML 3.2
- minimal use of JavaScript in the user interface (degrades gracefully)
- no cookies
- no CSS
You can easily add functionality, by customizing
TWikiTemplates, for one, while tailoring the browser requirements to your situation.
Known Issues
- The TWikiPlugins feature currently does not have compatibility guidelines for developers. Plugins can require just about anything - browser-specific functions, stylesheets (CSS), Java applets, cookies, specific Perl modules,... - check the individual Plugin specs.
- Plugins included in the TWiki distribution do not add requirements.
