I know it's a bit early to ask, but when do you think there will be a stable release of the new version? I'm planning to re-build up my VPS from scratch, but I would definitely wait for the new ISPConfig. Nginx support is more then welcome, well done!
I don't have the ressources to test this beta so here comes a theoretical question: how does the nginx support look like? what exactly does this ISPCFG version do to support nginx? can I select which webserver to run for a particular site? i.e. chose to run some sites on apache and some on nginx? Does ISPCFG do nginx configs or do we still have to modify those manually? I would be happy to use ISPCFG for general management of quota, and other services but completely switch to nginx and ditch apache. even if it means I have to do manual work to get nginx running for all my sites. does ispcfg set the right ownership user/group for sites created to be run on nginx?
ISPConfig does the same for a nginx setup that it does for a apache setup, so its a full configuration as usual. If you have a multiserver setup, then you can switch which website is created on a nginx server and which on a apache server. You can not run apache and nginx on the same server.
Do you have a link to the description of the new features? i.e. vserver - what exactly can it do? Can I use an existing Debian Squeeze installation and replace apache with nginx just like that? If more is needed, any how-tos?
The new manual contains already the description of all features and settings. The online demo is also up to date, so you can see the new features there too. No. Apache and Nginx use different config file formats and also require a different PHP configuration. In the manual there is a configuration guide for Nginx included and there will be perfect server tutorials for nginx installations available soon too.
