之前在tornado学习中(一）中，写了一个启停的脚本，来启动多个端口，但是其中没有日志部分。我将脚本修改一下，使其能支持启动输出日志。具体可见早起笔记http://www.simonzhang.net/?p=1170

            listen_port=$[${listen_start}+${i}]

             if [ -z "${now_pid}" ] ; then
                 echo ${i} "is stop"
             else
                 echo ${now_pid}
             fi
        done

	$0 stop
	$0 start
	;;
  *)
        echo $"Usage: $0 {start|stop|restart|status}"
        exit 1
esac

exit $rc

main.py 也需要修改，下面简单列出日志相关的代码。

import  tornado.options
import logging

if __name__ == "__main__":
    listen_port =  sys.argv[1]
    tornado.options.options['logging'].set(sys.argv[2])
    tornado.options.options['log_file_prefix'].set(sys.argv[3])
    tornado.options.options['log_file_max_size'].set(int(sys.argv[4]))
    tornado.options.parse_command_line()
    application.listen(listen_port)
    tornado.ioloop.IOLoop.instance().start()
