Hi @cforgaci,
Could you request the VPS at the Top desk service with the following configuration ( please feel free to adapt the name of the application and the qualified domain):
Here are the DCC guides on requesting the VPS Here's the administrator's guide to Shiny Server configuration
Thanks, @alwil! VPS requested!
Steps taken please note that step 2. (shiny pacakge installation) diverges from the installation instructions :
Shiny Server version: Shiny Server v1.5.20.1002
1) sudo apt-get install r-base
2)
sudo su
R -e "install.packages('shiny', repos='https://cran.rstudio.com/')"
exit
3) sudo apt-get install gdebi-core
4) wget https://download3.rstudio.org/ubuntu-18.04/x86_64/shiny-server-1.5.20.1002-amd64.deb
5) sudo gdebi shiny-server-1.5.20.1002-amd64.deb

@alwil, the Shiny server is up and running at http://mintemu_shiny.bk.tudelft.nl:3838/ Can you please check the deployment of our shiny app on it?
I had some problems with installing devtools
. I've managed to find workarounds, but it led to some conflicts and eventually plots not showing even in the Shiny examples. It had to do with some conflict in the ragg
package that has been installed but not recognized by shiny server.
I ended up removing all the libraries and reinstalling R.
I've ended up installing devtools
the following way, based on stackoverflow suggestions:
sudo apt-get install r-cran-devtools
FYI, logs for applications can be found in the location: /var/log/shiny-server/
the app is running, but crashes instantly, as the package data is not available. I tired to move the data manually, but it's not trivial in the package context. The two ways to go about it are 1) reinstall the mintEMU package on the server once the datasets are added to the github repository 2) created a 'static' version of the app, that includes datasets in its folder and adapt the script slightly.
The app is up and running in it's 'static version'. it can be accessed through: http://mintemu_shiny.bk.tudelft.nl:3838/mintemu/
On the server side, it is located in /srv/shiny-server/mintemu/
.
The code from the mintEMU
package app is copied from the app_ui.R
and app_server.R
scripts to the ui.R
and server.R
files, respectively. This means that whenever there is an update in the package Shiny app, the changes would need to be copied manually to those scripts. Similarly, the emu_clean.rda
and emu_metadata.rda
data sets have been manually added to the data
folder and would need to be updated when there's any change.
In the long run, i.e. once there's a stable version of a dataset that is stored as a part of the package, the mintEMU
package should be reinstalled with the following code:
sudo su
R -e "devtools::install_github('UD3-Lab/mintEMU')"
exit
Then the package folder needs to be identified in the server. it can be done with the command:
sudo su
R -e "system.file('mintEMUapp', package = 'mintEMU')"
exit
Finally, it needs to be copied to the /srv/shiny-server/
directory:
sudo cp -R <mintEMUapp directory> /srv/shiny-server/
