Finding and installing the prerequisites
From OpenCms Wiki
Download Opencms:
Of course you need opencms itself.
To run opencms you need:
- A database system that is supported by opencms
- Java 1.4 or higher
- A servlet container (aka. 'servlet engine') that forms the basis for running opencms
The most well-tested open source components for getting started with opencms are:
- The Mysql, Version 4.0 or higher as database system
- Sun Java 1.5
- Jakarta Tomcat, Version 5.0 or higher as servlet container
- It is not totally necessary, but a good idea to install a webserver like Apache, for handling all requests that arrive at your website.
