Hello...
I'm interested in taking a look at Pachyderm. We normally run all our web apps on Mac OSX servers. However, we currently don't have a spare that we can test Pachyderm on. We do have access to a Linux server.
The current download I have is version 2.0.4. The "read me" only provides the Mac OSX server install. Because Pachyderm is utilizing WebObjects, how would I go about installing Pachyderm on to a linux server? Are there some installation guides for Linux?
Thank you!
We have had some past successes with Linux installations, but unfortunately we don't have a clean installer to make it all happen easily. We're long overdue for a 2.0.5 release, as 2.0.4 needs updating to be in par with what's in the 2.0.x branch. My attentions have been on development for the 2.1 branch, so I apologize nothing has come out here. Perhaps next week I'll get a chance to do a release. For now, you can work with the 2.0.4 release.
Tim Steiner from University of Nebraska was the member of our community that got a successful Linux install working, and I haven't gotten him to record his methods, but it's much the same as a Mac install, except where it resembles the WIndows installs such as make edits to the mod_proxy for Apache so apache will forward to the running pachyderm instance, and since WebObjects doesn't come pre-installed on Linux, you'll need to copy over ther WebObjects jars and make sure they're in the application classpath.
The basic steps in any installation of Pachyderm are similar:
1) copy the code to the correct locations
- wwwroot files go in your web root under your web server directory
- Application woa goes in the location you want your code base to live.
- jars and frameworks need to be in your application's class path
- XML files need to be in a location you store your configurations
2) Install supporting software
- MySql (4.x or 5.x+)
- ImageMagick
- Apache (1.x or 2.x) with mod_proxy (or mod_webobjects if you want to compile it. The code can be found on a macintosh in /System/Library/WebObjects/Adaptors/Apache, and it can be compiled for any platform to run w/ Apache)
- If you want, you can grab the supporting java apps too, to run the webobjects task daemon and the java monitor (not necessary, but helps managing multiple instances): these can be found on a macintosh in /System/Library/WebObjects/JavaApplications/.
- You can also configure Pachyderm to run inside a Application Server, such as JBoss or Tomcat, though I'm not as up on how to get that done. It is possible, but not necessary, as you can run the code directly.
- Make sure you have the WebObjects libraries available in the class path. These can be gotten off a mac as well ( /Library/WebObjects/lib for the jars, or we should have them packaged up in our release download inside the Pachyderm.woa (Pachyderm2.woa/Contents/Resources/Frameworks/). This is how the Windows installs functions, so Linux can do the same.
3) create the pachyderm user in the database, create the pachyderm database, and load the data from the sql scripts. use the mac script for linux, because it paths the same way.
4) go in to the apdefault table in the database and make sure you have all the paths set correctly for the values. This will differ significantly, depending on your particulare set-up.
5) Edit the APOLLOProperties.plist values appropropriately to your installation
6) you can test the Pachyderm app by running the Pachyderm2.woa/Pachyderm2 script, but it will open up on a port such as 8080 or 8000.
7) in order to forward the traffic correctly (and have non-app resources found, such as css files, images, presentations, etc.) you'll need to port forward from Apache to WebObjects. This is done through mod_proxy or mod_webobjects.
8) permissions and directories may have to be adjusted to get everything running correctly.
At this point, if you've done everything right, you'll have a running instance. I know I've left out a great deal of the details here, but I'd use the Mac and Windows instructions for guidance until someone can write up a coherent set of instructions for Linux.
