由于工作需要本文主结合了excel表格，对表格中的ssh密码进行批量修改

以下是详细代码（python3）：

#!/usr/bin/env python
#-*-coding:utf-8-*-import paramiko
import socket
import pandas as pddef demo(Ip,user,old_password,new_password):
# 建立一个sshclient对象
ssh = paramiko.SSHClient()
# 允许将信任的主机自动加入到host_allow 列表，此方法必须放在connect方法的前面
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
# 调用connect方法连接服务器
#如果远程执行命令错误信息是b'the input device is not a TTY\n' 去掉docker exec -it 中的t就好了
try:
ssh.connect(hostname=Ip, port=22, username=user, password=old_password,timeout=5)
#ubuntu修改密码两种方法
#方法一
# command1 = "echo '%s:%s' | chpasswd"%(user,new_password)
# stdin, stdout, stderr = ssh.exec_command(command1)
# out, err = stdout.read(), stderr.read()
# if err != '':
# print(err)
#
# else:
# print(out)
# # 关闭连接
# ssh.close()
#方法二
command = "passwd %s" %(user)
stdin, stdout, stderr = ssh.exec_command(command)
#\n模拟回车输两次密码
stdin.write(new_password + '\n' + new_password + '\n')
out, err = stdout.read(), stderr.read()
successful = 'password updated successfully'
#print(out,err)
if successful in str(err):
print(Ip + " 密码修改成功！")
else:
print('\033[31m错误：\033[0m' + str(err))
print(Ip + " 密码修改失败！")
# 关闭连接
ssh.close()
except paramiko.ssh_exception.AuthenticationException as e:
print(Ip + ' ' + '\033[31m账号密码错误!\033[0m')
with open('nossh.txt','a') as f:
f.write(Ip + '\n')
except socket.timeout as e:
print(Ip + ' ' + '\033[31m连接超时！\033[0m')
with open('timeoutssh','a') as f:
f.write(Ip + '\n')

def Red_Excel(IP):
import sys
import time
file = r'E:\xxx.xlsx'
pd.set_option('display.max_columns', None)
pd.set_option('display.max_colwidth', 1000)
n = pd.read_excel(file,sheet_name='xxx') #表格中的sheet名
#print(n.values)
#显示含某字段的特定行
n1 = (n.loc[n['IP']==IP])
if not n1.empty:
n2 = n1.values
ip = n2[0][1]
user = n2[0][4]
password_old = n2[0][5]
password_new = n2[0][22]
houtai = n2[0][16]
print('IP：%s 账号：%s 旧密码：%s 是否后台：%s 新密码：%s' % (ip, user, password_old, houtai,password_new))
demo(ip,user,password_old,password_new)
else:
print('记录表无此IP！')
