Install the latest nginx from source for Ubuntu 14.04

nginx-latest.sh

# Automatically instal the latest nginx
wget -O - http://nginx.org/keys/nginx_signing.key | sudo apt-key add -

#Make a backup copy of your current sources.list file
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

#Now copy the following repositories to the end of ` /etc/apt/sources.list`
echo "deb http://nginx.org/packages/mainline/ubuntu/ trusty nginx" | sudo tee -a /etc/apt/sources.list
echo "deb-src http://nginx.org/packages/mainline/ubuntu/ trusty nginx" | sudo tee -a /etc/apt/sources.list

#If you want to use the 'stable' branch take:
#echo "deb http://nginx.org/packages/ubuntu/ trusty nginx" | sudo tee -a /etc/apt/sources.list
#echo "deb-src http://nginx.org/packages/ubuntu/ trusty nginx" | sudo tee -a /etc/apt/sources.list

#update to get the new repository
sudo apt-get update
sudo apt-get install nginx

## Longer way ##
## Manually build and install the latest nginx ##

#Install the PCRE library needed by nginx
sudo apt-get install libpcre3 libpcre3-dev

#Replace by the latest version number found on http://nginx.org/
wget http://nginx.org/download/nginx-1.7.4.tar.gz

tar -xvf nginx-1.7.4.tar.gz

cd nginx-1.7.4

#These flags make sure to put nginx somewhere that is usuall in PATH and to activate the https module
./configure --sbin-path=/usr/local/sbin --with-http_ssl_module

make

sudo make install

# Download nginx startup script
wget -O init-deb.sh http://library.linode.com/assets/660-init-deb.sh

# Move the script to the init.d directory & make executable
sudo mv init-deb.sh /etc/init.d/nginx
sudo chmod +x /etc/init.d/nginx

# Add nginx to the system startup
sudo /usr/sbin/update-rc.d -f nginx defaults

# This automatically adds the nginx.conf from below into /etc/init/nginx.conf
# If something doesn't work, just copy it manually
sudo wget -O /etc/init/nginx.conf https://gist.githubusercontent.com/Globegitter/685e3739c0f181bda3ec/raw/6ec0def52ed49d29b2f00cae70d28689371d0230/nginx.conf

#This will make sure you get the following commands
#sudo service nginx start
#sudo service nginx stop
#sudo service nginx restart
#sudo service nginx status

##Now you can modify your nginx.conf in /usr/local/nginx/conf

nginx.conf
