通过提供的 RPM 在 CentOS 7 VM 上安装 IDAS 的问题

Question

我一直在尝试通过UL2.0 RPMs（下载链接！）在其catalogue page 中的CentOS 7 VM 中安装IDAS GE。

我按照 github 上的说明进行操作，但按照说明部署部分的 section 3 启动 IoT 时遇到了困难。如果我执行 init_iotagent.sh，我在其中插入了 VM 的本地 IP，我会收到错误：

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

另外，在启动 IoTAgent as a Service 的说明中，它说：

安装 iot-agent-base RPM 后，可以在以下位置找到 init.d 脚本 这个文件夹 /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。

另外，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。

如果有人可以提供帮助，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，然后将其安装在您的 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

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：
