デーモン化したWEBrickのpidを取得する

Last updated at Posted at 2015-08-17
require 'webrick'

@log = open("pid", "w")

s = WEBrick::HTTPServer.new(
  :Port          => 3000,
  :ServerType    => WEBrick::Daemon,
  :StartCallback => Proc.new {
    @log << $$
    @log.close
  }
)
s.start

:StartCallback の中で $$ を参照すれば取得できる。pidファイルなどに書き出してやれば良い(๑˃̵ᴗ˂̵)و
