剛自學完python一點基礎，只是用來練習~~~~~~

需求：只開啟crond|network|sshd|rsyslog|sysstat服務，其余設置為關閉狀態

shell腳本實現過程：

#!/bin/bash

for i in `chkconfig --list|grep "3:啟用"|awk '{print $1}'|grep -vE "crond|network|sshd|rsyslog|sysstat"`

do

chkconfig $i off

done

Python腳本實現過程：

#!/usr/local/python3/bin/python3

import subprocess

import re

chushi = ["crond","network","sshd","rsyslog","sysstat"]

data = subprocess.getoutput("chkconfig --list")

def file_w(datas):

with open("/tmp/output.txt","w",encoding="utf-8") as f_w:

for line in datas:

f_w.write(line)

f_w.write("\n")

return chushi

def file_r(lis):

guanbi = []

with open("/tmp/output.txt","r",encoding="utf-8") as f_r:

for line in f_r:

#print(line.strip())

valu = re.search("\w+",line.strip()).group()

#print(valu)

if valu not in lis:

guanbi.append(valu)

else:

pass

return guanbi

def send_os(gb):

for item in gb:

subprocess.getoutput("chkconfig %s off" % item)

a = file_w(data)

b = file_r(a)

send_os(b)

基本的思路：先把所有的系統服務列表輸出到文件，然後進行讀取，和需要開啟服務的列表做匹配，再調用系統命令進行關閉
