paramiko模块基于SSH用于连接远程服务器并执行相关操作。
1. SSHClient
用于连接远程服务器并执行基本命令
基于用户名密码连接：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
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='192.168.0.2', port=22, username='root', password='test') # 执行命令 stdin, stdout, stderr = ssh.exec_command('df') # 获取命令结果 result = stdout.read().decode() # 关闭连接 ssh.close() |
SSHClient 封装 Transport
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
import paramiko transport = paramiko.Transport(('192.168.0.2', 22)) transport.connect(username='root', password='test') ssh = paramiko.SSHClient() ssh._transport = transport stdin, stdout, stderr = ssh.exec_command('df') print(stdout.read().decode()) transport.close() |
基于公钥密钥连接：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |
import paramiko private_key = paramiko.RSAKey.from_private_key_file('/home/auto/.ssh/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='192.168.0.2', port=22, username='root', key=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() |
