Python-Paramiko项目实战(一)

远程执行命令

iimport os
import paramiko


def client_ssh_conn(host_name,passwd,command):
	#创建sshclient
	clint = paramiko.SSHClient()
	#自动添加密钥到know_hosts文件
	client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
	#连接服务器，填充账号和密码
	client.connect(hostname=host_name,port=22,username=root,password=passwd)
	#远程执行命令
	stdin, stdout, stderr = client.exec_command('command')
	#获取命令结果
	print (stdout.read().decode('utf-8'))
	#关闭连接
	client.close()

#打开文件
with open("/opt/python/host_list.txt",'r') as host_file:
	#for循环读取
	for host in host_file:
		data = host.strip('\n')
		#传入参数
		host_name,passwd,command = data.split(',')
		print (f'--------{host_name}--------')
		#调用client_ssh_conn(）
		client_ssh_conn(host_name,passwd,command)

/opt/python/host_list.txt内容如下

192.168.1.1，password01，df -h
192.168.1.2，password02，date
192.168.1.3，password03，cat /etc/passwd
192.168.1.4，password04，cat /etc/hosts
192.168.1.5，password05，hostname
