1、用戶名、密碼登陸方式

import paramiko paramiko.util.log_to_file('paramiko.log') # 記錄日志文件 ssh = paramiko.SSHClient() try:ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())ssh.connect('139.xx.xx.xx', username='work', password='***')cmd = 'ls' # 需要執行的Linux命名stdin, stdout, stderr = ssh.exec_command(cmd) #執行命令后的結構print(stdout.readlines())print(stdout.read().decode()) except Exception as e:print("%s:%s" % (e.__class__, e)) finally:# 關閉ssh.close() View Code 2、免密登陸方式
import paramiko ssh = paramiko.SSHClient() SSH_PRIVATE_KEY ='/Users/xueerhuan/.ssh/id_rsa' #本地密鑰文件路徑try:key = paramiko.RSAKey.from_private_key_file(SSH_PRIVATE_KEY) # 無解密密碼時#key = paramiko.RSAKey.from_private_key_file(SSH_PRIVATE_KEY, password='******') # 有解密密碼時, ssh.load_system_host_keys() #通過known_hosts 方式進行認證可以用這個,如果known_hosts 文件未定義還需要定義 known_hosts#ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) # 通過公共方式進行認證 (不需要在known_hosts 文件中存在) ssh.connect(hostname='139.XX.XX.XX', port=22, username='root', pkey=key)stdin, stdout, stderr = ssh.exec_command("ps")# 獲取命令結果result = stdout.read()# 打印輸出print(result.decode()) except Exception as e:print("%s:%s" % (e.__class__, e)) finally:# 關閉ssh.close() View Code 注意：生成密碼的方法
A、進入本地 ssh文件夾 cd .ssh/
B、使用ssh-keygen生產本地公鑰和私鑰 ssh-keygen
xueerhuan@ubuntu:~/.ssh$ ls
id_rsa id_rsa.pub
C、將生成的id_rsa.pub文件中的內容copy到目標機的.ssh/authorized_keys中就可以了，如果沒有authorized_keys，自己創建。但是要注意authorized_keys的權限一般是600

或者直接在本地使用一條命令也可以實現公鑰的復制，ssh-copy-id后面接入的用戶就是要支持免密登錄的用戶。 morra@ubuntu:~/.ssh$ ssh-copy-id "morra@192.168.1.42" /usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/home/morra/.ssh/id_rsa.pub" The authenticity of host '192.168.1.42 (192.168.1.42)' can't be established. ECDSA key fingerprint is SHA256:/ufx+/OLtdsYy7vsdk4KDu9xJsBp6zHonRAf2jjT0GI. Are you sure you want to continue connecting (yes/no)? n^H Please type 'yes' or 'no': yes /usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys Password: Number of key(s) added: 1 Now try logging into the machine, with: "ssh 'morra@192.168.1.42'" and check to make sure that only the key(s) you wanted were added. #去目標機器下，檢查authorized_keys文件 localhost:.ssh morra$ cat authorized_keys 3、密碼上傳文件

import os import paramiko ssh = paramiko.SSHClient() SSH_PRIVATE_KEY ='/Users/xueerhuan/.ssh/id_rsa' #本地密鑰文件路徑 key = paramiko.RSAKey.from_private_key_file(SSH_PRIVATE_KEY) paramiko.util.log_to_file('paramiko.log')ssh = paramiko.SSHClient() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect('139.XX.XX.XX', username='root', password='***') t = ssh.get_transport() sftp = paramiko.SFTPClient.from_transport(t) d = sftp.put("mm.txt", "/home/work/.ssh/mm.txt") print(d) View Code

4、免密上傳文件

import os import paramiko ssh = paramiko.SSHClient() SSH_PRIVATE_KEY ='/Users/xueerhuan/.ssh/id_rsa' #本地密鑰文件路徑 key = paramiko.RSAKey.from_private_key_file(SSH_PRIVATE_KEY) paramiko.util.log_to_file('paramiko.log') ssh = paramiko.SSHClient() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect(hostname='139.XX.XX.XX', port=22, username='root', pkey=key) t = ssh.get_transport() sftp = paramiko.SFTPClient.from_transport(t) d = sftp.put("mm.txt", "/home/work/.ssh/mm.txt") print(d) View Code
