我在启动Upstart脚本时遇到问题.

这是脚本(/ etc/init /中的app.conf)

description "node.js server"
author      "kvz"

start on startup
stop on shutdown

script
   # We found $HOME is needed. Without it, we ran into problems
   export HOME="/root"

   exec sudo -u /usr/local/bin/node \
                /var/www/vhosts/travelseguro.com/node/app.js \
                2>&1 >> /var/log/node.log
end script

当我跑步时sudo start app,我得到:

开始:未知工作:app

我怎样才能做到这一点？
