if server_uri == ODDB::SERVER_URI
  ODBA.cache.setup

end

$ bin/oddbd atupri
$ bin/oddbd mymedi

connection from index.rbx

lookandfeels are called flavor in URL

z.B.

  • carenaschweiz

parse parameter and servername

  • doc/index.rbx
    • parse request-parameter in request via Apache
  • bin/oddbd
    • parse ARGV parameter in oddbd (bin/oddbd)
  1. when request comes to / (no flavor parameter)
  2. when request comes to /de/(flavor)/...

  • restart 
      svc -t /service/ch.oddb
  • kill

I created run a script for multi daemons.
But, This way dosen't works.
I could not control each process with svc command.

/var/www/oddb.org/svc/oddb/run [this does not work] 

#!/bin/sh
exec 2>&1
ulimit -v 10240000
exec sudo -u yasu /usr/local/bin/ruby /var/www/oddb.org/bin/oddbd
# lookandfeels
exec sudo -u yasu /usr/local/bin/ruby /var/www/oddb.org/bin/oddbd atupri
exec sudo -u yasu /usr/local/bin/ruby /var/www/oddb.org/bin/oddbd atupri-web
exec sudo -u yasu /usr/local/bin/ruby /var/www/oddb.org/bin/oddbd carenaschweiz
...

We must run 1 script per 1 daemon. (we could not run also as child process)
then, created as each service. 

#!/bin/sh
exec 2>&1
ulimit -v 10240000
exec sudo -u yasu /usr/local/bin/ruby /var/www/oddb.org/bin/oddbd
  • /var/www/oddb.org/svc/
    • oddbd
      • run
      • log
    • oddbd-atupri
      • run
      • log
    • oddbd-atupri-web
      • run
      • log
    • oddbd-atupri-carenaschweiz
      • run
      • log

...

We must run it by these commands. 

$ svc -u /service/ch.oddbd 
$ svc -u /service/ch.oddbd-atupri
$ svc -u /service/ch.oddbd-atupri-web 
$ svc -u /service/ch.oddbd-carenaschweiz
...
