Site design: Skeleton
While I use some outside providers for Internet services, specifically Amazon S3 for hosting demo versions of my applications, I prefer to keep most of my Internet services in-house; the flexibility and cost-reduction that such a setup offers make the trade-off in administrative time worth it. For this purpose, I have always relied on the server version of OS X for web hosting, mail serving, and related services. It provided a robust platform, and required an investment of time to master, but was worth it.
The new version of Lion server is significantly different from earlier versions of OS X Server. Rather than being a separate build of OS X that's optimized for being a server (with a $500 price tag to match), it's a $50 download from the Mac App Store called Server.app. Apple is promoting Server.app as "The Server for Everyone." That initially caught my eye, but this lower price also comes as a significantly simplified version of the previous server OS: it removes a great deal of functionality that previously existed in the server OS.
For my purposes, the biggest difference (read loss) is the ability to comprehensively configure the Apache web server from a GUI. Older versions of OS X Server allowed you to define domain names and customize the configuration of each domain, all from a single interface. It put the power of Apache configuration at your fingertips without requiring you to hand-hack configuration files, with their arcane syntax. By contrast, Server.app on Lion allows you to define multiple websites, set one or two options, and turn them on from the GUI--that's about it.
For someone who uses the server to host a dozen websites, this is a serious issue. It's one that other reviews have noted as well. It means that if I want to provide advanced configuration of my websites, I have to hand-edit configuration files, much as if I were managing the Apache web server on a Linux or Unix system. Additionally, Apple provides little documentation on how to do this in such a way that won't cause problems with Apache. (To clarify: I am certainly capable of hand-editing Apache configuration files, but previous versions of OS X Server discouraged this because Apple's version of Apache had many Apple-specific customizations that could be best managed from the GUI; manual changes to the config files could be overwritten by the GUI or, even worse, break Apache.)
After a lot of trial and error, I finally worked out a process to configure my sites so that they would support the customizations I wanted (CGI execution, domain alias, and files with *.htm suffixes ). Here it is, with the "Code by Kevin" site as a demonstration:
sudo serveradmin stop web
DirectoryIndex index.html index.php /wiki/ default.html index.htm
CustomLog "/var/log/apache2/access_log" combinedvhost
SSLProtocol -ALL +SSLv3 +TLSv1
SSLProxyProtocol -ALL +SSLv3 +TLSv1
Options All +MultiViews +ExecCGI -Indexes
AddHandler cgi-script .cgi
sudo serveradmin start web
Re-start Server.app. It should read the updated configuration files.
This approach is mostly undocumented by Apple, and I have not seen it documented in its entirety elsewhere on the Web either. Part of my purpose in documenting this here is to assist anyone else who might be frustrated by the limited functionality of the GUI tools in Lion Server for Apache configuration. (It's a mystery to me why Apple removed this functionality. The other hugely complex configuration that I deal with in the server, mail configuration, can still be managed from the GUI tools in Lion Server; the workflow is a bit different, with the advanced options removed from Server.app and placed in another program (Server Admin), but it's all still there, one way or another.)
I am certainly please to see the reduced financial cost of server support in Lion, but especially with web configuration, Lion Server incurs other costs. I don't want to discourage anyone from buying Lion Server, but you do need to be aware of its limitations.
