Internet Information Services
Internet Information Services (IIS) is the web server software bundled with Windows Server, as well as certain client versions of Windows.
PHP installation
It is strongly recommended to use only the official Microsoft PHP installer from http://php.iis.net/, it automatically installs all necessary components and facilitates easy configuration with PHP manager. Manual installation attempts often fail or may not allow Moodle to function properly.
Configuration
Unfortunately IIS does not natively support unicode characters in so called slashargument URL which are used in Moodle for file serving. Moodle requires manual configuration of rewrite rules, the PHP installation via Microsoft Web Platform Installer installs necessary URL Rewrite 2.0 module. Add following rewrite rule to enable support for unicode file names in Moodle:
- Matches the Pattern - Regular Expressions -
^([^\?]+?\.php)(\/.+)$ - Action - Rewrite -
{R:1}\?file={R:2}- Append query string
Directory permissions
The default IIS account is IIS_IUSRS, make sure it has appropriate access right to Moodle dirroot (read only) and dataroot (read/write) directories.
Debugging problems
By default IIS contains custom error pages that intentionally hide error details on production sites. When diagnosing problems you may want to disable temporarily the IIS Error Pages.
