web_server D1189734872 Amaht #The Plan 9 web server httpd(8) has some interesting features. It #also kept me scratching my head all day getting it going so I #thought I'd share a few things. # #When the httpd runs it sets itself to user "none" and runs newns(2) #and then addns(2) using the namespace provided on the command line #(or /lib/namespace.httpd if you didn't give it a -n). This means #that whatever you supply for the nsamespace file has to exist in the #new namespace. ip/httpd/httpd -n /cfg/$sysname/namespace.httpd was #my solution. # #While experimenting I had the problem of how to kill a process owned #by none, here's how to do it : # #! p = `{ps | grep httpd} #! chmod 777 /proc/$p(2) ^/note && echo kill > /proc/$p(2) ^/note # #I'm assuming only one program called httpd is running, of course. # #For extra fun ip/httpd/mirror was missing from my distribution (Sept #07) and I didn't notice for ages. # #momo here is a Unix box running u9fs -a none and I'm using a #terminal to play on so termrc it is # #cat /cfg/$sysname/termrc # #! fn start_httpd { #! rfork #! bind /n/momo/home/plan9/httpd /usr #! bind /usr/httpd.rewrite /sys/lib/httpd.rewrite #! ip/httpd/httpd -n /cfg/$sysname/namespace.httpd #! } #! #! 9fs momo #! #! start_httpd & # #The folder /n/momo/home/plan9/httpd has in it : # #! bin/ #! web/ #! httpd.rewrite # #cat /cfg/$sysname/namespace.httpd # #! mount /srv/momo /n/momo #! bind /n/momo/home/plan9/httpd/bin /bin/ip/httpd # #So now my /magic/ files are kept on momo so I don't pollute #/bin/ip/httpd # #I also found a bug with vhosts and submitted a patch(1) #httpd-post-port because vhosts running on non-default port were #impossible as the :port was being stripped when the vhosts were #parsed but not when matching http requests. Leaving the :port on is #the correct behaviour according to RFC 2616 14.23. #
