System Requirements

Operating System

• A UNIX or BSD-like operating system on your server: Linux, MacOSX, Solaris or something similar.
• CorneliOS runs fine on MacOSX, you don't need the MacOSX Server version to use it (Tiger, Leopard and Snow Leopard are okay).
• CorneliOS does NOT run on Windows/IIS servers - at least not yet!

Apache webserver

• The Apache webserver must be installed and running, Apache 2.x or better is recommended. Apache 1.x should also be okay, but it's not officially supported.
• Apache is installed on most systems by default, including most Linux distributions and MacOSX.

Perl / CGI

• Perl 5.8 must be installed, Perl 5.10 or better is recommended. Perl 5.6 should also be okay, but it's not officially supported.
• Perl is installed on most systems by default, including most Linux distributions and MacOSX.
• There must be a /cgi-bin directory allowing to execute CGI scripts.
• Server Side Includes SSI must be enabled.
• In most cases you'll have to install DBI / DBD::mysql manually if you'd like to use the MySQL database features.

mod_rewrite - recommended, but not required

• CorneliOS itself does NOT require mod_rewrite.
• CIOS community platforms may require mod_rewrite, which means that it's always good to enable it.

mod_perl - recommended, but not required

• CorneliOS will run on any Apache installation, no matter if mod_perl is available or not.
• Install mod_perl on your server to increase the performance of the CorneliOS system by a factor of 10 to 20!
• CorneliOS automatically detects mod_perl, it will run under mod_perl without modifications.

MySQL - recommended, but not required

• The CorneliOS core system will run without any SQL database. Even the CMS doesn't require a database.
• A database is required to run the so called "SQL applications", which are important parts of the system - therefore we strongly recommend to install an SQL database.
• CorneliOS currently only supports MySQL. MySQL 5 or better is recommended.
