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.
sudo apt-get install -y apache2 libapache2-mod-proxy-html libxml2-dev
Configure the Apache2 server
cd /etc/apache2/sites-available/
sudo cp 000-default.conf 000-default.conf.backup
sudo wget https://rawgit.com/greenore/AWS-Setup/master/rstudio.conf -O 000-default.conf
Then, to update the Apache configuration files to activate mod_proxy you execute the following commands:
sudo a2enmod proxy
sudo a2enmod proxy_http
Enable the host and test Apache configuration.
sudo apachectl configtest
sudo service apache2 reload
On Debian or Ubuntu a version of Nginx that supports reverse-proxying can be installed using the following command:
sudo apt-get install -y 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
sudo apt-get update
sudo apt-get install -y git
Configure GIT, i.e., define the author name to be used for all commits in the current repository. Typically, you’ll want to use the --global flag to set configuration options for the current user.
git config --global user.name <name>
git config --global user.email <email>

The OpenCPU cloud server sets a memory limit RLIMIT_AS on every request using the RAppArmor package. This is to prevent a single user from consuming all resources on a server. The default limit is 1GB per process. You can configure these limits by editing:
sudo nano /etc/opencpu/server.conf
sudo service opencpu restart
The Linux kernel provides a tweakable setting that controls how often the swap file is used, called swappiness. The swappiness parameter controls the tendency of the kernel to move processes out of physical memory and onto the swap disk. Because disks are much slower than RAM, this can lead to slower response times for system and applications if processes are too aggressively moved out of memory.
A swappiness setting of zero means that the disk will be avoided unless absolutely necessary (you run out of memory), while a swappiness setting of 100 means that programs will be swapped to disk almost instantly.
Ubuntu comes with a default of 60, meaning that the swap file will be used fairly often if the memory usage is around half of the RAM. Check the system's swappiness value by running:
cat /proc/sys/vm/swappiness
The value can be turned down to 30 or so. The swap file will then only be used when the RAM usage is around 70 percent. To change the system swappiness value, run
sudo cp /etc/sysctl.conf /etc/sysctl.conf.backup
sudo sh -c 'echo "\n# System swappiness setting\nvm.swappiness = 30" >> /etc/sysctl.conf'
Reboot for the change to take effect
