简单的连接 查看一下磁盘信息
import paramiko # 创建SSH对象 ssh = paramiko.SSHClient() # 允许连接不在know_hosts文件中的主机 ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) # 连接服务器 ssh.connect(hostname='172.16.2.225', port=22, username='root', password='123456') # 执行命令 stdin, stdout, stderr = ssh.exec_command('df') # 获取命令结果 result = stdout.read() # 关闭连接 ssh.close() print(result.decode('utf-8'))
从服务器上传下载文件
import paramiko transport = paramiko.Transport(('172.16.2.225', 22)) transport.connect(username='root', password='123456') sftp = paramiko.SFTPClient.from_transport(transport) #上传到服务器 #sftp.put('test.txt', '/root/test.txt') #从服务器下载到本地 sftp.get('/root/test.txt', 'xx.txt') transport.close()
连接服务器的两种方式
- 用户名和密码
- 公钥和私钥（rsa）
- 生成公钥和私钥 把公钥放到服务器
- 以后再连接服务器时，不需要在输入密码
- 第一步 生成公私钥
ssh-keygen -m pem
第二部 拷贝公钥到服务器
ssh-copy-id -i id_rsa.pub root@172.16.2.225
从此 连接无需密码 注：生成公私钥，可以二次加密
私钥连接服务器
import paramiko from io import StringIO #private_key = paramiko.RSAKey(file_obj=StringIO(key)) private_key = paramiko.RSAKey.from_private_key_file(r'id_rsa') # 创建SSH对象 ssh = paramiko.SSHClient() # 允许连接不在know_hosts文件中的主机 ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) # 连接服务器 ssh.connect(hostname='172.16.2.225', port=22, username='root', pkey=private_key) # 执行命令 stdin, stdout, stderr = ssh.exec_command('df') # 获取命令结果 result = stdout.read() # 关闭连接 ssh.close() print(result.decode('utf-8'))
私钥上传下载文件
import paramiko private_key = paramiko.RSAKey.from_private_key_file(r'id_rsa') transport = paramiko.Transport(('172.16.2.225', 22)) transport.connect(username='root', pkey=private_key) sftp = paramiko.SFTPClient.from_transport(transport) #上传 sftp.put('1.txt', '/root/1.txt') #下载 #sftp.get('/root/1.txt', 'local.txt') transport.close()
另外一种读取私钥，在内存中
