paramiko模块使用

该模块基于ssh用于连接远程服务器并执行相关操作。
SSHClient 用于连接远程服务器并执行基本命令

pip3 install paramiko

# 基于用户名和密码
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='10.0.0.12', port=22, username='root', password='mysql')
# 执行命令
stdin, stdout, stderr = ssh.exec_command('df -Th')
# 获取命令结果
result = stdout.read().decode('utf8')
# 关闭连接
ssh.close()
stdout.close()
print(result)

# SSHClient封装Transport
import paramiko
transport = paramiko.Transport(('10.0.0.12', 22))
transport.connect(username='root', password='mysql')
ssh = paramiko.SSHClient()
ssh._transport = transport
stdin, stdout, stderr = ssh.exec_command('df')
result = stdout.read().decode()
transport.close()
print(result)

# 基于公钥和私钥，请提前执行ssh-copy-id
# ssh-copy-id -i 公钥 [email protected]
# ssh-copy-id -i id_rsa.pub [email protected]
# ssh [email protected]
import paramiko

# 私钥的地址

# 创建ssh对象

# 连接服务器
ssh.connect(hostname='10.0.0.12', port=22, username='root', pkey=private_key)
# 执行命令
stdin, stdout, stderr = ssh.exec_command('df -Th')
# 获取命令结果

# 关闭连接
