我需要在ubuntu上注册乘客nginx模块作为服务，并且在系统重启或关机的情况下需要自动启动。
最后我找到了解决办法：
wget -O init-deb.sh http://library.linode.com/assets/1139-init-deb.sh mv init-deb.sh /etc/init.d/nginx chmod +x /etc/init.d/nginx /usr/sbin/update-rc.d -f nginx defaults sudo service nginx start or sudo /etc/init.d/nginx start sudo service nginx restart or sudo /etc/init.d/nginx restart sudo service nginx reload or sudo /etc/init.d/nginx reload sudo service nginx stop or sudo /etc/init.d/nginx stop 更多信息请访问：
