如何使用Python实现服务器远程登录并执行命令

pip install paramiko

import paramiko
import datetime
import os

# 配置项
remote_host = "x.x.x.x"
remote_user = "youruser"
remote_password = "yourpassword"
file_path = "/data/test.log"


def check_file_consistency():
    ssh = paramiko.SSHClient()
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

    try:
        ssh.connect(remote_host, username=remote_user, password=remote_password)
        print(f"✅ 连接成功: {remote_host}")
        # 使用md5命令校验文件一致性
        compress_cmd = f"md5sum {file_path}"
        sh.exec_command(compress_cmd)
        output = shell.recv(1024).decode()
        print(f"✅ 输出内容：{output}")
        
    except Exception as e:
        print(f"❌ 出错: {e}")
    finally:
        ssh.close()

# 执行函数
check_file_consistency(file_path)

import paramiko
import datetime
import os

# 配置项
remote_host = "x.x.x.x"
remote_user = "youruser"
remote_password = "yourpassword"
remote_log_dir = "/data/test.log"

def check_file_consistency(file_path):
    ssh = paramiko.SSHClient()
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    file_full_path = get_file_path() + get_file()
    try:
        ssh.connect(remote_host, port=remote_port, username=remote_user, password=remote_password)
        print(f"✅ 登录成功: {remote_host}")
        # 启动交互式 shell
        shell = ssh.invoke_shell()
        time.sleep(2)
        shell.recv(1024)
        # 要执行的命令
        command = f'sudo md5sum {file_path}\n'
        # 发送命令
        shell.send(command)
        # 等待命令执行完成
        time.sleep(3)
        shell.send(remote_password + '\n')
        time.sleep(2)
        # 获取返回值
        output = shell.recv(1024).decode()
        print(f"✅ 输出内容：{output}")
    except paramiko.AuthenticationException as e:
        print("❌ 认证失败:", e)
    except Exception as e:
        print(f"❌ 出错: {e}")
    finally:
        ssh.close()
        
# 执行函数
check_file_consistency(file_path)
