python运维脚本执行_zz【Python运维】简单的Python运维脚本

背景

最近在Windows 10上使用Linux子系统&＃xff0c;发现它有一个非常坑爹的特点&＃xff1a;Linux子系统是没有开机关机状态的&＃xff0c;每次进入Bash shell就自动载入&＃xff0c;退出后Linux子系统的所有进程都会被关闭&＃xff0c;如果你撞了Mysql之类的服务要想随时运行的话就要保持Bash shell的随时开启&＃xff0c;更坑的是这些服务并不会随之进入Bash shell而自动启动&＃xff0c; 我只好写一个Python脚本用于管理这些服务。

Python3, argparse module

代码

1 from os importsystem

2 from argparse importArgumentParser

3

4 defstart_service(service):

5 system("service {} start".format(service))

6

7 defstop_service(service):

8 system("service {} stop".format(service))

9

10 defrestart_service(service):

11 print(service)

12 system("service {} restart".format(service))

13

14 defmanage_service():

15 services &＃61;[]

16 services.append("xinetd")

17 services.append("lighttpd")

18 returnservices

19

20 defset_args():

21 parser &＃61;ArgumentParser()

22 parser.add_argument("service", help &＃61; "the service to be managed.")

23 parser.add_argument("-s", "--start", help &＃61; "start the service(s).", action &＃61; "store_true")

24 parser.add_argument("-r", "--restart", help &＃61; "restart the service(s).", action &＃61; "store_true")

25 parser.add_argument("-p", "--stop", help &＃61; "stop the service(s).", action &＃61; "store_true")

26 returnparser.parse_args()

27

28 defdeal(args,services):

29 globalstart_service, restart_service, stop_service

30 services &＃61; services if not args.service else services if args.service &＃61;&＃61; "all"else[args.service]

31 operation &＃61; start_service if args.start else restart_service if args.restart elsestop_service

32 for service inservices:

33 operation(service)

34

35 if __name__ &＃61;&＃61; "__main__":

36 deal(set_args(),manage_service())

运行

开启服务

(env) root&＃64;DESKTOP-1DDIIV2:~# python pyops.py all -s

initctl: 无法连接到 Upstart: Failed to connect to socket /com/ubuntu/upstart: 拒绝连接

* Starting internet superserver xinetd [fail]

* Starting web server lighttpd [ OK ]

(env) root&＃64;DESKTOP-1DDIIV2:~#

关闭服务

(env) root&＃64;DESKTOP-1DDIIV2:~# python pyops.py xinetd -p

initctl: 无法连接到 Upstart: Failed to connect to socket /com/ubuntu/upstart: 拒绝连接

* Stopping internet superserver xinetd [ OK ]

(env) root&＃64;DESKTOP-1DDIIV2:~#

重启服务

(env) root&＃64;DESKTOP-1DDIIV2:~# python pyops.py xinetd -r

xinetd

initctl: 无法连接到 Upstart: Failed to connect to socket /com/ubuntu/upstart: 拒绝连接

* Stopping internet superserver xinetd [ OK ]

* Starting internet superserver xinetd [ OK ]

(env) root&＃64;DESKTOP-1DDIIV2:~#

感想

Python脚本还是比shell脚本好写很多啊。
