Python3 script for remote bulk modification of file contents

First, Description:

1, using the Python Paramiko module, invoke remote shell command to modify the corresponding file.

2, there is a private profile, lists the server list.

3. Python loops through the server IP of the configuration file to connect to it and executes the corresponding command.

4, the main is a regular, matching Zabbix agent in the IP settings.

[Email protected] ~]# sed-i ' s/^server=[0-9]*\. [0-9]*\. [0-9]*\. [0-9]*/server=33.66.88.99/g ' zabbix_agentd.conf

The contents of the script are as follows:

#! /usr/bin/env python#-*-coding:utf-8-*-# __author__ = "Life" # Email: [email protected]# date:2017/12/28import par Amikolist_file_content = []def read_file (): With open (' ip-list ', ' RU ', encoding= ' Utf-8 ') as F1:for i in F1.readli NES (): List_file_content.append (I.strip ()) print (list_file_content) def ssh_conn (hosts): For host in hosts : Print (host) ssh = Paramiko.
