[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
        4、其他问题待发现，联系QQ群: 24967504

    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
