场景分析;
2.实例代码;
1.安装相关支持包
pip3 install pycrypto
pip3.6 install paramiko
2.远程执行命令示例代码;
#!/usr/bin/env python36
from multiprocessing import Process
import paramiko
import sys
Username = 'root'
Password = 'P@ssw0rd'
Port = 22
TimeOut = 60
def runCmd(ip,cmd):
s = paramiko.SSHClient()
s.set_missing_host_key_policy(paramiko.AutoAddPolicy())
try:
s.connect(hostname=ip, port=Port, username=Username, password=Password,timeout=TimeOut)
stdin, stdout, stderr = s.exec_command(cmd)
result = stdout.read()
print(ip,result)
except:
print("is not exists") + ip
def ipProcess():
try:
cmd = sys.argv[1]
for i in range(4,16):
ip = '172.21.38.%s' % i
p = Process(target=runCmd,args=(ip,cmd))
p.start()
except IndexError:
print("please input a command")
if __name__ == '__main__':
ipProcess()
3.执行结果;
python3.6 bbc_init.py uptime
4.封装远程命令执行和文件上传;
#!/usr/bin/env python
# -*- coding:utf-8 -*-
