摘要：相關(guān)技術(shù)代碼運(yùn)行開啟服務(wù)無法連接到拒絕連接關(guān)閉服務(wù)無法連接到拒絕連接重啟服務(wù)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(tǒng)，發(fā)現(xiàn)它有一個(gè)非常坑爹的特點(diǎn)：Linux子系統(tǒng)是沒有開機(jī)關(guān)機(jī)狀態(tài)的，每次進(jìn)入Bash shell就自動載入，退出后Linux子系統(tǒng)的所有進(jìn)程都會被關(guān)閉，如果你撞了Mysql之類的服務(wù)要想隨時(shí)運(yùn)行的話就要保持Bash shell的隨時(shí)開啟，更坑的是這些服務(wù)并不會隨之進(jìn)入Bash shell而自動啟動， 我只好寫一個(gè)Python腳本用于管理這些服務(wù)。

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())

Python腳本還是比shell腳本好寫很多啊。
