[Python]用python实现批量/

  针对前面的代码 http://lxsym.blog.51cto.com/1364623/1065854，还存在的问题进行了改善:     1、去掉明文密码，通过交互输入密码     2、通过传参执行相关命令,增加灵活性     3、异常处理

具体代码：

#!/usr/bin/env python #-*- coding: utf-8 -*- import sys import paramiko import threading import getpass def main():     try:         cmd = sys.argv[1:]         username = "root"         passwd = getpass.getpass('Please input password: ')         threads = [4]         f = file('list.txt')         while True:             ip = f.readline()             if len(ip) == 0:                 break             a = threading.Thread(target=ssh2,args=(ip,username,passwd,cmd))             a.start()         f.close()     except:          pass

def ssh2(ip,username,passwd,cmd):     try:         ssh = paramiko.SSHClient()         ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())         ssh.connect(ip,22,username,passwd,timeout=5)         for m in cmd:             stdin,stdout,stderr = ssh.exec_command(m)             stdin.write("Y")             out = stdout.readlines()             for o in out:                 print o,         print '[OK]%s' %(ip),         print '========================================================================='         ssh.close()     except:         print '[Error]%s' %(ip),         print '========================================================================='

if __name__ == '__main__':     main() 执行结果： [root@bw-vm-soft test]# python ssh2.py 'md5sum /usr/local/webserver/nginx/conf/nginx.conf'  Please input password: 33066988953224e936028b341f4e1337  /usr/local/webserver/nginx/conf/nginx.conf [OK]192.168.13.116 ========================================================================= 33066988953224e936028b341f4e1337  /usr/local/webserver/nginx/conf/nginx.conf [OK]192.168.13.117 =========================================================================

若密码不对 [Error]192.168.13.116 ========================================================================= [Error]192.168.13.117
