Apache is one of the most well known web servers and this could be attributed to its antiquity.
To run jaris on apache make sure that you properly configure it with mod-php which is php running embedded as an apache module and the most easier to configure or with php running in fast cgi mode. In either of the methods that you choose we recommend you to follow the official apache documentation to get up and running.
Besides enabling mod_rewrite in the Apache configuration there shouldn't be a need for any further configuration, since the needed rewrite rule is included in the .htaccess file which is automatically read on each request that apache process.
