Assuming you're logged in as root add these users and login as "not root."
adduser deploy
adduser [yourname] #optionally
vim /etc/group
# add your users to the sudo group like so:
sudo:x:27:isaac,deploy
vim /etc/ssh/sshd_config
# add to file or if they exist set the flags to no.
ChallengeResponseAuthentication no
PasswordAuthentication no
UsePAM no
service ssh restart
su - deploy # or your username. The important thing is that you use a user other than root.
Make sure that each line completes before running the next. Don't just copy the lines in all at once or it will use the beginning letters of one line as an answer to questions the first may ask.

I usually install sshguard to help protect my server from being hacked.

Run:
swapon -s
If you don't see any swapfiles you should create one like so:
sudo fallocate -l 1G /swapfile
sudo chown root:root /swapfile
sudo chmod 0600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
sudo bash -c "echo '/swapfile none swap sw 0 0 ' >> /etc/fstab"
gem install passenger
sudo passenger-install-nginx-module # if you installed ruby with rvm use "rvmsudo"
The following lines will setup you nginx configs with sites-enabled and sites-available directories. This way you can keep you config a lot cleaner as you won't ever have to edit the main conf file.
sudo sed -i '1iuser deploy rvm;' /opt/nginx/conf/nginx.conf #use replace staff with rvm as group if installed.
sudo sed -i '36iinclude /opt/nginx/conf/sites-enabled/*;' /opt/nginx/conf/nginx.conf
sudo sed -i '36iserver_names_hash_bucket_size 64;' /opt/nginx/conf/nginx.conf
sudo mkdir /opt/nginx/conf/sites-enabled
sudo mkdir /opt/nginx/conf/sites-available
To setup the following commands for nginx:
sudo service nginx stop
sudo service nginx start
sudo service nginx restart
run:
wget -O init-deb.sh https://www.linode.com/docs/assets/660-init-deb.sh
sudo mv init-deb.sh /etc/init.d/nginx
sudo chmod +x /etc/init.d/nginx
sudo /usr/sbin/update-rc.d -f nginx defaults
Clone your rails app to a directory owned by deploy. Then create a file in /opt/nginx/conf/sites-available/ called yourdomain.com.
sudo touch /opt/nginx/conf/sites-available/yourdomain.com
Edit /opt/nginx/conf/sites-available/yourdomain.com with your favorite editor and add:
server {
listen 80;
server_name yourdomain.com;
return 301 http://www.yourdomain.com$request_uri;
}
server {
client_max_body_size 40M;
listen 80;
server_name www.yourdomain.com;
root /path/to/your/railsapp/public; # <--- be sure to point to 'public'!
passenger_enabled on;
}
Then enabled your site by symlinking your conf file to sites-enabled and restarting nginx.
sudo ln -s /opt/nginx/conf/sites-available/yourdomain.com /opt/nginx/conf/sites-enabled/yourdomain.com
sudo service nginx restart
All done. Enjoy!
