远程批量操作主机

  • ansible： 需要被控主机安装python
  • fabric： 被控主机支持ssh即可，但目前不怎么维护了

    # 创建一个 ThreadingGroup 对象
    group = Group(*hosts, user='root', connect_kwargs={'password': 'Admin@123.perf'})

    # 并行执行任务
    results = group.run(f'{cmd} {arg1}', hide=True)

    # 处理结果
    for connection, result in results.items():
        print(f'{connection.host}:\n{result.stdout}')

@task
def put(c, script):
    # 创建一个 ThreadingGroup 对象
    group = Group(*hosts, user='root', connect_kwargs={'password': 'Admin@123.perf'})

    for connection in group:
        remote_path = f"/tmp/{script.split('/')[-1]}"
        connection.put(script, remote_path)
