1、用户名、密码登陆方式
import paramiko paramiko.util.log_to_file(‘paramiko.log‘) # 记录日志文件 ssh = paramiko.SSHClient() try: ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect(‘139.xx.xx.xx‘, username=‘work‘, password=‘***‘) cmd = ‘ls‘ # 需要执行的Linux命名 stdin, stdout, stderr = ssh.exec_command(cmd) #执行命令后的结构 print(stdout.readlines()) print(stdout.read().decode()) except Exception as e: print("%s:%s" % (e.__class__, e)) finally: # 关闭 ssh.close()
2、免密登陆方式
import paramiko ssh = paramiko.SSHClient() SSH_PRIVATE_KEY =‘/Users/xueerhuan/.ssh/id_rsa‘ #本地密钥文件路径 try: key = paramiko.RSAKey.from_private_key_file(SSH_PRIVATE_KEY) # 无解密密码时 #key = paramiko.RSAKey.from_private_key_file(SSH_PRIVATE_KEY, password=‘******‘) # 有解密密码时, ssh.load_system_host_keys() #通过known_hosts 方式进行认证可以用这个,如果known_hosts 文件未定义还需要定义 known_hosts #ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) # 通过公共方式进行认证 (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") # 获取命令结果 result = stdout.read() # 打印输出 print(result.decode()) except Exception as e: print("%s:%s" % (e.__class__, e)) finally: # 关闭 ssh.close()
注意：生成密码的方法
A、进入本地 ssh文件夹 cd .ssh/
B、使用ssh-keygen生产本地公钥和私钥 ssh-keygen
xueerhuan@ubuntu:~/.ssh$ ls
id_rsa id_rsa.pub
C、将生成的id_rsa.pub文件中的内容copy到目标机的.ssh/authorized_keys中就可以了，如果没有authorized_keys，自己创建。但是要注意authorized_keys的权限一般是600
或者直接在本地使用一条命令也可以实现公钥的复制，ssh-copy-id后面接入的用户就是要支持免密登录的用户。
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.
#去目标机器下，检查authorized_keys文件
localhost:.ssh morra$ cat authorized_keys 3、密码上传文件
import os import paramiko ssh = paramiko.SSHClient() SSH_PRIVATE_KEY =‘/Users/xueerhuan/.ssh/id_rsa‘ #本地密钥文件路径 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)
4、免密上传文件
import os import paramiko ssh = paramiko.SSHClient() SSH_PRIVATE_KEY =‘/Users/xueerhuan/.ssh/id_rsa‘ #本地密钥文件路径 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)
