SSL free with Certbot and nginx

Really simple with https://certbot.eff.org/

Install Nginx

sudo apt install nginx

• Update default config /etc/nginx/sites-available/default

server {
    listen 80 default_server;
    listen [::]:80 default_server;

    root /var/www/html;
    index index.html index.htm index.nginx-debian.html;

    server_name _;

    location / {
        # First attempt to serve request as file, then
        # as directory, then fall back to displaying a 404.
        try_files $uri $uri/ =404;
    }
}

• Add virtual application by creating new config /etc/nginx/sites-available/nhancv.com

server {
    listen 80;
    listen [::]:80;

    root /home/nhancao/nhancv.com;
    index index.html index.htm;

    server_name nhancv.com www.nhancv.com;

    location / {
        try_files $uri $uri/ /index.html?$query_string;
    }
}

• Make alias

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

• Reload config

sudo service nginx reload
