linux使用Python上秘鑰遠程登錄ssh執行shell

單臺登錄：

#! /bin/bash
# -*- coding: utf-8 -*-
import paramiko

ssh = paramiko.SSHClient()
key = paramiko.AutoAddPolicy()
ssh.set_missing_host_key_policy(key)
pkey = paramiko.RSAKey.from_private_key_file('/root/.ssh/id_rsa')

ssh.connect('103.11.30.2', 22, 'root', pkey ,timeout=5)
stdin, stdout, stderr = ssh.exec_command('ls')
print(stdout.read().decode())
print(stderr.read())
# 關閉連接
ssh.close()

逐行讀取多個IP多臺登陸，如下

#!/usr/bin/python
# -*- coding: utf-8 -*-

import time,shutil,os
import paramiko

appname = "root"
ssh = paramiko.SSHClient()
key = paramiko.AutoAddPolicy()
ssh.set_missing_host_key_policy(key)
pkey = paramiko.RSAKey.from_private_key_file('/root/.ssh/id_rsa')

uptime = time.strftime("%Y%m%d")
warpath="/var/tmp/cslc/aw/update/"+uptime

def update_all_aw():
    for line in open("awip.conf"):
        print line
        ssh.connect(line, 22, appname, pkey ,timeout=5)
        stdin, stdout, stderr = ssh.exec_command('python /var/tmp/awpy/createcopy.py')
        print(stdout.read().decode())
        print(stderr.read())
        ssh.close()
        print("+++++++下一個++++++")
    return

awip.conf文件防止多臺IP地址即可。
