摘要：相關技術代碼運行開啟服務無法連接到拒絕連接關閉服務無法連接到拒絕連接重啟服務無法連接到拒絕連接感想腳本還是比腳本好寫很多啊。

最近在Windows 10上使用Linux子系統，發現它有一個非常坑爹的特點：Linux子系統是沒有開機關機狀態的，每次進入Bash shell就自動載入，退出后Linux子系統的所有進程都會被關閉，如果你撞了Mysql之類的服務要想隨時運行的話就要保持Bash shell的隨時開啟，更坑的是這些服務并不會隨之進入Bash shell而自動啟動， 我只好寫一個Python腳本用于管理這些服務。

Python3, argparse module

from os import system
from argparse import ArgumentParser

def start_service(service):
    system("service {} start".format(service))

def stop_service(service):
    system("service {} stop".format(service))

def restart_service(service):
    print(service)
    system("service {} restart".format(service))

def manage_service():
    services = []
    services.append("xinetd")
    services.append("lighttpd")
    return services

def set_args():
    parser = ArgumentParser()
    parser.add_argument("service", help = "the service to be managed.")
    parser.add_argument("-s", "--start", help = "start the service(s).", action = "store_true")
    parser.add_argument("-r", "--restart", help = "restart the service(s).", action = "store_true")
    parser.add_argument("-p", "--stop", help = "stop the service(s).", action = "store_true")
    return parser.parse_args()

def deal(args,services):
    global start_service, restart_service, stop_service
    services = services if not args.service else services if args.service == "all"else [args.service]
    operation = start_service if args.start else restart_service if args.restart else stop_service
    for  service in services:
       operation(service)

if __name__ == "__main__":
    deal(set_args(),manage_service())
