paramiko模块初探

import paramiko
import sys
def sshExecmd(hostname,port,username,password,cmd):
    ssh_client=paramiko.SSHClient()
    ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    try:
        ssh_client.connect(hostname,port,username,password)
    except Exception as e:
        print(e)
        sys.exit()
    stdin,stdout,stderr=ssh_client.exec_command(cmd);
    print(stdout.read().decode(encoding='utf-8'),end='')
    ssh_client.close()
if __name__ == '__main__':
    servers={
        "192.168.1.3":{
            'username':'root',
            'passwd':'123456',
            'port':22
        }
    }
    cmd='df -h'
    for ip,info in servers.items():
        sshExecmd(hostname=ip,port=info.get('port'),username=info.get('username'),password=info.get('passwd'),cmd=cmd)
