Rstudio-server deployment

After installing the two server with super user previledges, we can’t directly run the servers because the path to R has not been set.

The configuration file of rstudio-server lies at /etc/rstudio/rserver.conf
We shall append the following line:

rsession-which-r=/home/csj/anaconda3/envs/r411py37/bin/R

More options, such as port, external lib paths, could also be set in the rserver.conf file (see details at https://support.rstudio.com/hc/en-us/articles/200552316-Configuring-RStudio-Workbench-RStudio-Server)

Run the following command to verify if rstudio-server was configured successfully.

sudo rstudio-server verify-installation

we can manage the rstudio-server with the following commands
sudo rstudio-server status
sudo rstudio-server start
sudo rstudio-server stop
sudo rstudio-server restart

The default port of rstudio-server is 8787.

 

Shiny-server deployment

run the following code first before starting the server
export R=/home/csj/anaconda3/envs/r411py37/bin

the path to R shall be configured at /etc/shiny-server/shiny-server.conf

we can change the configurations here

# Define a server that listens on port 3838
server {
listen 3838;

# Define a location at the base URL
location / {

# Host the directory of Shiny Apps stored in this directory
site_dir /srv/shiny-server;

# Log all Shiny output to files in this directory
log_dir /var/log/shiny-server;

# When a user visits the base URL rather than a particular application,
# an index of the applications available in this directory will be shown.
directory_index on;
}
}

start the server with
sudo systemctl start shiny-server
