Step 6: Install Nginx on Ubuntu 16.04

Installing Nginx on Ubuntu is very easy. Run the following command to install it:

sudo apt-get install nginx

Create Nginx virtual server block for your domain name:

sudo nano /etc/nginx/sites-available/phxsolution.com

Paste the following content:

server {
    listen 80;
    server_name phxsolution.com www.phxsolution.com;
    root /var/www/phxsolution.com;
    index index.php;

    location / {
            try_files $uri $uri/ =404;
    }

    location ~ \.php$ {
        fastcgi_pass unix:/run/php/php7.1-fpm.sock;
        include snippets/fastcgi-php.conf;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

    location ~ /\.ht {
            deny all;
    }
}

Of course, you should replace phxsolution.com with your actual domain name. Save and close the file. To enable the server block in Nginx you need to create a symbolic link to site-enabled. Use the following command to create a symbolic link:

sudo ln -s /etc/nginx/sites-available/phxsolution.com /etc/nginx/sites-enabled/phxsolution.com

Check if there are errors with the configuration:

sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

If the syntax is OK and there are no errors you can restart Nginx.

sudo systemctl restart nginx.service

Enable Nginx and PHP-FPM on system boot:

sudo systemctl enable nginx.service
sudo systemctl enable php7.1-fpm.service
