linux使用Python上秘钥远程登录ssh执行shell

单台登录：

#! /bin/bash# -*- coding: utf-8 -*-import paramikossh = 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())# 关闭连接ssh.close()

逐行读取多个IP多台登陆，如下

#!/usr/bin/python# -*- coding: utf-8 -*-import time,shutil,osimport paramikoappname = "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/"+uptimedef 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("+++++++下一个++++++")    return

awip.conf文件防止多台IP地址即可。
