用paramiko多线程SSH登陆华为交换机处理简单的命令。

前面提到过可以用netconf来管理交换机，可是我们的交换机没有提前开启netconf。难道要一台台登陆上开，NO NO...下面介绍用paramiko登陆交换批量修改。

首先建一个交换机信息文件hz_sw_ip.py，主要保存交换机名与管理地址，重点是后面的管理地址要能SSH登陆到交换机，内容如下

hz_ip={
'1F-E03-ES' : '192.168.45.62',
'1F-E04-kvm' : '192.168.45.67',
'1F-E10-kvm   ' : '192.168.45.68',
'4F-A32-kvm   ' : '192.168.45.13',
'4F-A34-kvm   ' : '192.168.45.14',
'4F-A36-kvm   ' : '192.168.45.57',
};

再建一个远程登陆执行命令文件：enablenetconf.py

#-*- coding: utf-8 -*-
#!/usr/bin/python 
import paramiko
import threading
import time
from hz_sw_ip import hz_ip  #导入交换机信息
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)
        ssh_shell = ssh.invoke_shell()  #使用invoke是为了可以执行多条命令
        print ssh_shell.recv(1024)
        for m in cmd:
            res = ssh_shell.sendall(m+'\n')
            time.sleep(float(1))
        print ssh_shell.recv(1024)
        ssh.close()
    except :
        print '%s\tError\n'%(ip)


if __name__=='__main__':
    cmd = ['sys','snetconf server enable','commit'] #你要执行的命令列表
    username = "wsf535"  #用户名
    passwd = "*****"    #密码
    threads = [10]   #多线程
    print "Begin......"
    for key in hz_ip:
        ip = hz_ip[key]
        a=threading.Thread(target=ssh2,args=(ip,username,passwd,cmd))
        a.start()

执行:python enablenetconf.py 查看运行过程。
