Overview
If you are running RStudio on a public network it is strongly recommended that you deploy RStudio behind another web server (e.g. Nginx or Apache) which acts as a reverse proxy to it. Doing this allows you to benefit from the the robust HTTP protocol handling built into the web server. This has both performance (e.g. keep-alive) and security (e.g. rejection of maliciously malformed requests) benefits.
Nginx Configuration
On Debian or Ubuntu a version of Nginx that supports reverse-proxying can be installed using the following command:
sudo apt-get install nginx
To enable an instance of Nginx running on the same server to act as a front-end proxy to RStudio you would add commands like the following to your nginx.conf
file:
http {
server {
listen 80;
location / {
proxy_pass http://localhost:8787;
proxy_redirect http://localhost:8787/ $scheme://$host/;
}
}
}
If you want to serve RStudio from a custom path (e.g. /rstudio) you would edit your nginx.conf
file as shown below:
location /rstudio/ {
rewrite ^/rstudio/(.*)$ /$1 break;
proxy_pass http://localhost:8787;
proxy_redirect http://localhost:8787/ $scheme://$host/rstudio/;
}
After adding these entries you'll then need to restart Nginx so that the proxy settings take effect:
sudo /etc/init.d/nginx restart
Apache Configuration
To enable an instance of Apache running on the same server to act as a front-end proxy to RStudio you need to use the mod_proxy
. The steps for enabling this module vary across operating systems so you should consult your distribution's Apache documentation for details.
On Debian and Ubuntu systems Apache can be installed with mod_proxy
using the following commands:
sudo apt-get install apache2
sudo apt-get install libapache2-mod-proxy-html
sudo apt-get install libxml2-dev
Then, to update the Apache configuration files to activate mod_proxy
you execute the following commands:
sudo a2enmod proxy
sudo a2enmod proxy_http
Once you have enabled mod_proxy
in your Apache installation you need to add the required proxy commands to your VirtualHost
definition. For example:
<VirtualHost *:80>
<Proxy *>
Allow from localhost
</Proxy>
ProxyPass / http://localhost:8787/
ProxyPassReverse / http://localhost:8787/
</VirtualHost>
Note that if you want to serve RStudio from a custom path (e.g. /rstudio) you would replace the ProxyPass directives described above to:
ProxyPass /rstudio/ http://localhost:8787/
ProxyPassReverse /rstudio/ http://localhost:8787/
RedirectMatch permanent ^/rstudio$ /rstudio/
Finally, after you've completed all of the above steps you'll then need to restart Apache so that the proxy settings take effect:
sudo /etc/init.d/apache2 restart
RStudio Configuration
Once you are successfully proxying requests from Nginx or Apache to RStudio you should change the port RStudio listens on from 0.0.0.0 (all remote clients) to 127.0.0.1 (only the localhost). This ensures that the only way to connect to RStudio is through the proxy server. You can do this by adding the www-address
entry to the /etc/rstudio/rserver.conf
www-address=127.0.0.1
Note that this config file does not exist by default so you may need to create it if it doesn't already exist.
