Installing a LEMP Stack on Ubuntu Linux
Before we can start building our world-changing website or application on LEMP, we have to lay the foundation for the stack. In this hands-on lab, we will walk through the installation of the components that make up the LEMP stack on Ubuntu Linux. We will also configure th eUbuntu Linux environment to host the LEMP stack. When we have completed this lab, we will have a running LEMP stack on Ubuntu. We will also have a better understanding of how a LEMP installation is configured on Ubuntu Linux.

Install NGINX Using the Default Ubuntu Package Repositories
Become the
rootuser:sudo su -Install NGINX from the Ubuntu repositories using
apt-get:apt-get -y install nginxCheck the status of the NGINX service with
systemctl:systemctl status nginxThe NGINX service should be enabled and active.

Challenge
Configure HTTP Access Through the Firewall
Check the initial status of the firewall:
ufw statusOpen port 80 to allow inbound HTTP traffic:
ufw allow 'Nginx HTTP'Recheck the status of the firewall:
ufw statusHTTP traffic is now allowed through the firewall.

Challenge
Verify Basic HTTP Functionality in NGINX
Verify that we can load the default NGINX web page using
curl:curl http://`curl v4.ifconfig.co`Use a web browser to go to the default NGINX web page at http://OUR_PUBLIC_IP_ADDRESS or http://OUR_PUBLIC_DNS. We should see the default NGINX page. We can find the public IP address and DNS of our instance in the
/home/cloud_user/server_info.txtfile. -
Challenge
Install the PHP Components
Install the PHP components using
apt-get:apt-get -y install php-fpm php-mysql -
Challenge
Activating the Virtual Host Configuration
To make the bigstatecollege.edu virtual host active, we create a symlink to the appropriate configuration file in the
sites-enableddirectory:ln -s /etc/nginx/sites-available/bigstatecollege.edu.conf /etc/nginx/sites-enabled/bigstatecollege.edu.confValidate the NGINX configuration before reloading the NGINX service:
nginx -tsystemctl reload nginxRestart the
php-fpmservice:systemctl restart php7.2-fpm.service -
Challenge
Verifying PHP Functionality in NGINX
Test PHP by loading the phpinfo page on bigstatecollege.edu. We are providing a header (via the
-Hswitch) so NGINX knows to route the request to the www.bigstatecollege.edu virtual host:curl -H "www.bigstatecollege.edu" http://www.bigstatecollege.edu/phpinfo.phpWe can add our server's public IP address, pointing at www.bigstatecollege.edu, to our computer's
hostsfile if we want to access the phpinfo page at http://www.bigstatecollege.edu/phpinfo.php with a web browser. -
