Disable directory listing in OpenCPU

由 帅比萌擦擦* 提交于 2019-12-12 03:45:19
问题 I have been trying to disable directory listing in OpenCPU so our users cannot see the resulting directories and files in the http://server/ocpu/tmp/ directory. I have followed Apache's Directory Listing Configuration and deleted every mention of Indexes in the conf files in /etc/apache2/ and included Options -Indexes in the sites-enabled/opencpu.conf file (in the Location tags) without success. I also looked at the rApache documention without finding any pertinent entry. Does anyone know any

问题 I have an R package that sends out a job to the OpenMPI cluster I have running by means of the Rmpi package. All works as expected within an R session run from the console. However, when I try to execute the relevant function with from my OpenCPU server like this (details changed to protect the innocent): curl -XPOST http://99.999.999.99/ocpu/library/MyPackage/R/my_cluster_function I get this error: R call failed: process died.

Task model for long-running jobs in OpenCPU?

由 强颜欢笑 提交于 2019-12-08 04:51:13
问题 To my knowledge, there is no task model in OpenCPU, i.e. one has to wait arbitrarily long with an open TCP connection until the request finishes. One possibility for a task model implementation would be to return a dedicated task uri with status 200 OK immediately for a POST request when one wishes to running a function. The advantage would be that the client would get a result immediately while the job runs on the server in the background. The client would then poll the task URI until it

How to start/stop/flush OpenCPU on CentOS6?

由 两盒软妹~` 提交于 2019-12-07 12:37:12
问题 I've successfully built and installed OpenCPU and RStudio Server on a CentOS6. Everything is working as expected, and I do get successful GET/POST responses for my local R packages. A couple of things that don't seem to work however: I can't figure a clean way to start/stop/flush OpenCPU. I'm currently using apachectl restart but I'm not even sure that does reload R packages as expected. I tried Jeroen's bash scripts at /usr/lib/opencpu/scripts but they seem to require quite a bit of tweaking
