sails/src/config/ssl/letsencrypt.md

+Para tener el servidor funcionando con certificados gratuitos de Let's encrypt los pasos son los siguientes:
+
+```
+$ cd
+$ git clone https://github.com/letsencrypt/letsencrypt
+$ sudo mkdir /etc/letsencrypt
+$ sudo chown ubuntu:ubuntu /etc/letsencrypt
+$ vim /etc/letsencrypt/cli.ini
+```
+
+Con el contenido siguiente:
+
+```
+authenticator = webroot
+webroot-path = /home/ubuntu/pictogram/sails/src/assets/
+server = https://acme-v01.api.letsencrypt.org/directory
+renew-by-default
+agree-dev-preview
+agree-tos
+email = info@yottacode.com
+```
+
+Para permitir a letsencrypt verificar nuestro servidor, debemos facilitar la entrada por HTTP. Para ello instalamos nginx y lo configuramos para que redirija a HTTPS:
+
+```
+$ sudo apt-get install nginx
+$ sudo vim /etc/nginx/site-enabled/default
+```
+
+Con el siguiente contenido:
+
+```
+server {                         
+        listen 80 default_server;
+        listen [::]:80 default_server ipv6only=on;
+        server_name _;                       
+        return 301 https://$host$request_uri;
+}  
+```
+
+Ahora relanzamos nginx y solicitamos el certificado
+
+```
+$ sudo service nginx reload
+$ /home/ubuntu/letsencrypt/letsencrypt-auto --config /etc/letsencrypt/cli.ini -d dev.yottacode.com certonly
+```
+
+Ya tenemos nuestros certificados. Finalmente configuramos Sails para que apunte a ellos:
+
+```
+$ vim /home/ubuntu/pictogram/sails/src/config/local.js
+```
+
+Con el contenido para ssl:
+
+```
+   ssl: {
+       key: fs.readFileSync('/etc/letsencrypt/live/dev.yottacode.com/privkey.pem'),
+       cert: fs.readFileSync('/etc/letsencrypt/live/dev.yottacode.com/cert.pem')   
+   },    
+```
+
+Ya podemos relanzar sails
+
+```
+$ cd /home/ubuntu/pictograms/sails/src
+$ sudo forever stopall
+$ sudo forever start app.js --debug
+```
+
+Y ahora configurar cron para que el certificado se renueve solito cada mes
+
+```
+$ sudo crontab -e
+```
+
+Añadimos la línea:
+
+```
+@monthly /home/ubuntu/letsencrypt/letsencrypt-auto --config /etc/letsencrypt/cli.ini -d dev.yottacode.com certonly
+```
+
+y voila!
