Python multi-process batch management host;

1. Scene analysis;

           

   2. The example code;

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. The results of the implementation;

python3.6 bbc_init.py uptime

4. Package remote command execution and file upload;
