fiware - 通过提供的 RPM 在 CentOS 7 VM 上安装 IDAS 时出现问题

Question

我一直在尝试通过 UL2.0 RPMs 在我的计算机上的 CentOS 7 VM 中安装 IDAS GE (下载链接!)可在其 catalogue page 中找到.

我按照 github 上的说明进行操作，但我陷入了按照section 3启动物联网的困境。说明的部署部分。如果我执行 init_iotagent.sh(在其中插入了虚拟机的本地 IP)，则会收到错误:

log4cplus:ERROR No appenders could be found for logger (main).
log4cplus:ERROR Please initialize the log4cplus system properly.
HTTPFilter DESTRUCTOR 0
HTTPFilter DESTRUCTOR 0

此外，在启动 IoTAgent 作为服务的说明中，还提到:

After installing iot-agent-base RPM an init.d script can be found in this folder /usr/local/iot/init.d .

但是这个文件不存在，让我相信 IoTAgent 没有从提供的 RPM 中正确安装。

此外，我找不到有关 IoTAgent 的日志文件，只有 MongoDB 的日志文件位于/usr/local/iot/mongodb-linux-x86_64-2.6.9/log/mongoc.log。

如果有人能提供帮助，我们将不胜感激。另外，如果需要更多信息，请告诉我。

谢谢

我建议您获取 GitHub 存储库并从源代码构建 RPM，然后将其安装在 CentOS 中。就像文档中解释的那样:

注意:我将 BUILD_TYPE 更改为 Release，因此我创建了 Release 目录。 GIT_VERSION 和 GIT_COMMIT 不是最新的。

git clone https://github.com/telefonicaid/fiware-IoTAgent-Cplusplus.git
cd fiware....
mkdir -p build/Release
cd build/Release
cmake -DGIT_VERSION=20527 -DGIT_COMMIT=217023407f25ed258043cfc00a46b6c05fb0b52c -DMQTT=ON -DCMAKE_BUILD_TYPE=Release ../../
make install
make package

软件包将位于 pack/Linux/RPM/

rpm -i iot-agent-base-xxxxxxx (xxxxxxx will be the numbers of the build)
rpm -i iot-agent-ul-xxxxxx (xxxxxxx will be the numbers of the build)

使用 RPM 安装后，init.d 文件位于:/usr/local/iot/init.d/iotagent

这是文件的内容:
