I have (at least) three different hosts,
- I started by following laptop wiki with git to create
a bare repo on
gitserver, and clone that to a workingdir on gitserver.
On the laptop clone gitserver:repo /working/dir
Next create a setup file for the laptop with
gitorigin_branch=> "", git_wrapper => "/working/dir/.git/hooks/post-commit",
At this point, assuming you followed page above, and not my hasty summary,
git commit -a
should rebuild the output of your wiki.
Now create a setup file for the server (I call it server.setup).
gitorigin_branch=> "origin", git_wrapper => "/repo/wiki.git/hooks/post-update.ikiwiki"
Note the non-standard and bizzare name of the hook.
edit /repo/wiki.git/hooks/post-update so that it looks something like
/repo/wiki.git/hooks/post-update.ikiwiki rsync -cavz /home/me/public_html/* webserver:/destdir
ikiwiki --setup server.setup
Now in principle when you run git push on the laptop, the git server will first do its "regular" thing and update ~/public_html (in my case) and then rsync it onto the webserver. For this to work, you need passwordless ssh or something like it.
