我的 tornado 启停脚本

  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

  start)
        /bin/rm -rf main.port
	for (( i=0 ; i<${listen_line} ; i++)); do
            listen_port=$[${listen_start}+${i}]
            echo ${listen_port} >> main.port
            python main.py ${listen_port} ${loglevel} ${log_file_prefix} ${log_file_max_size} &
	done
        echo "start ok !"
        ;;
  stop)
        get_port_line=`/bin/cat main.port`
        for i in ${get_port_line};do
             now_pid=`/bin/ps -ef|grep ${i}|grep -v grep|awk ' ''{print $2}'`
             /bin/kill -9 $now_pid
        done
        /bin/rm -rf *.pyc
        echo "stop"
        ;;
  status)
        get_port_line=`/bin/cat main.port`
        for i in ${get_port_line};do
             now_pid=`/bin/ps -ef|grep ${i}|grep -v grep`
             if [ -z "${now_pid}" ] ; then
                 echo ${i} "is stop"
             else
                 echo ${now_pid}
             fi
        done
	;;
  restart)
	$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()
