LEAPS 中心

LEAPS 中心 是一个网络应用程序，提供设备管理、网络管理以及整个网络的位置和遥测数据的可视化.

主要功能

  • 2D和3D网格提供实时位置更新，并将网络中的设备可视化.

  • 其他有用的功能包括用户管理、区域管理、区域历史、平面图管理、位置历史和位置热图.

  • The LEAPS 中心 通过 MQTT Broker 与 LEAPS 服务器 互联. 它作为一项服务在 Linux 和 Windows 上运行

安装

系统要求

Docker的系统要求因操作系统而异.

  • 对于 Linux，您需要 64 位架构、兼容的内核版本和特定的内核功能.

  • 在 Windows 上，在启用虚拟化的 Windows 10上使用 Docker Desktop

  • 在 macOS 上，请使用配备 macOS 10.13 或更新版本的Docker Desktop. 在硬件方面，建议至少配备 2GB 内存以及足够的 CPU 和磁盘空间.

注解

有关最新详情，请参阅`Docker <https://docs.docker.com/>`_官方文档.

说明

  1. 在电脑上安装 Docker

在 Linux 上安装 Docker Desktop <https://docs.docker.com/desktop/install/linux-install/>`_

此外，您还可以参考以下命令进行安装：

curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh ./get-docker.sh
sudo usermod -aG docker $USER

在 Windows 上安装 Docker Desktop <https://docs.docker.com/desktop/install/windows-install/>`_

在苹果电脑上安装Docker桌面

  1. 准备配置软件包

  • 创建包含 配置文件 的 leaps_center 目录

    • leaps-center-web.conf

    • 应用程序.属性

    • leaps-center-history.properties

    • leaps-center-web.properties

  • Or you can download the LEAPS 中心 configuration package (LEAPS_CENTER_DOCKER.zip).

  1. 在电脑上打开命令提示符或终端窗口.

  • Navigate to the directory where you extracted from the LEAPS 中心 configuration package.

例如，在 Ubuntu (Linux) 上：

cd LEAPS_CENTER_DOCKER/

  1. 安装 LEAPS 中心 Docker 软件包并运行：

docker run -d -p 80:8080/tcp --name some_name -v /path/to/data/data/:/app/data/ -e LEAPS_CENTER_HOME=/app/data/ leapslabs/leaps_center:tag sh -c "cd /app &&  java -jar leaps-center-web.jar"

其中 some_name 是要分配给容器的名称，tag 是指定要使用的 leaps-center-web 版本的标记.

leaps_center 映像必须与外部挂载的文件夹一起运行，该文件夹包含配置文件以及应用程序日志和配置/节点历史数据库的空间.

选项 -v /path/to/data/:/app/data/ 将位于 /path/to/data/ 的文件夹挂载到内部的 /app/data 文件夹. 数据文件夹必须包含以下文件.

  • 推荐的运行选项

    • --user $(id -u):$(id -g) 在特定用户和组下运行实例.

    • --restart unless-stopped 在服务器崩溃时自动重启实例.

  • 可选运行选项

    • --security-opt seccomp=unconfined 在 32 位 Raspberry Pi 镜像（Raspbian）上需要这个选项，因为它包含一个过时的 seccomp 库，其中的一个错误会对 Docker 镜像产生负面影响（无法连接到 MQTT 服务器）. 该选项允许我们覆盖这一问题.

例如，在 Ubuntu (Linux) 上：

docker run -d -p 80:8080/tcp --name leaps_center -v $PWD/leaps_center/:/app/data/ -e LEAPS_CENTER_HOME=/app/data/ leapslabs/leaps_center:latest sh -c "cd /app &&  java -jar leaps-center-web.jar"

  1. 确认安装成功，运行：

例如，在 Ubuntu (Linux) 上：

docker ps

网络配置

要配置网络，请进入菜单并选择 Networks.

../../../_images/lc_select_networks.png

网络管理对话框将弹出. 默认情况下已经设置了本地主机网络，网络 ID 为 0x1234.

../../../_images/lc_list_networks.png

要创建新网络，请单击右下角的 Add 按钮.

现在，填写所需的配置参数：

  • 名称

  • 网络类型

  • 主机

  • TCP 端口

  • 用户名

  • 主题前缀

填写完毕后，点击 Save 按钮连接并接收网络 ID.

../../../_images/lc_config_networks_1234.png

如果不知道网络 ID，可以使用 LEAPS 管理器 或 Shell 查找.

最后，您可以单击 Test 按钮检查连接情况，然后单击 Save 按钮保存配置.

节点配置

要配置节点，需要事先将节点分配到特定网络.

选择指定节点的网络，查看网络详细信息. 然后，您就可以开始配置节点了.

有关可配置为网关、锚点或标记节点的节点，请参阅以下详细信息

../../../_images/lc_config_gateway.png
../../../_images/lc_config_anchor.png
../../../_images/lc_config_tag.png

平面图

要配置平面图，请进入菜单并选择 Floor Plans.

../../../_images/lc_menu.png

点击右下角的 Add 按钮.

../../../_images/lc_floor_plans_add.png

然后，导入要配置的平面图并填写相应参数.

../../../_images/lc_floor_plans_create.png

填写完毕后，点击 Save 按钮保存配置. 使用 Visible 复选框启用地图上的可见性.

../../../_images/lc_floor_plans_udk1.png

区域

要配置区段，请进入菜单并选择 Zones.

../../../_images/lc_menu.png

点击右下角的 Add 按钮.

../../../_images/lc_floor_plans_add.png

然后，填写相应参数，并为 Save 添加配置.

用户

要配置用户，请进入菜单并选择 Users.

../../../_images/lc_menu.png

默认情况下，应用程序已预先配置了一个管理员账户和一个普通账户.

../../../_images/lc_user_list.png

适用于管理员账户或普通账户.

../../../_images/lc_user_admin.png
../../../_images/lc_user_common.png

应用程序接口授权

  1. 用户需要向/login发送一个简单的HTTP POST，并传递以下参数（以admin:admin为例）.

    • 用户名: admin

    • 密码：admin

    • 记住我：开启

  2. 登录后会生成 JSESSIONID cookie，用户需要在后续请求中使用它.

    注解

    1. 这不是强制性的，如果用户使用了它，会在响应中添加另一个 cookie（cookie REMEMBERME），用户可以在后续请求中使用它.

    2. @Todo: will be correct soon
