letsencrypt install configure on ubuntu / debian nginx

 

#1 Installing Letsencrypt Certbot on ubuntu

 

#a.Updating existing Packages & Adding Repository

run this command

sudo apt-get update && sudo add-apt-repository ppa:certbot/certbot

 

#2. Installing Nginx Plugin for Letsencrypt certbot

run below command to update the newly added repository

sudo apt-get update

and this command to install ppa nginx

sudo apt-get install -y python-certbot-nginx

 

#3 Configuring lets encrypt for ACME challenges (Imp)

Many Ways to do this. but i used this method for issuing all domains in server.

#a. Create a Directory & a Letsencrypt conf file

if snippets Directory not exists create it by

mkdir  /etc/nginx/snippets/

nano /etc/nginx/snippets/letsencrypt.conf

location ^~ /.well-known/acme-challenge/ {
        default_type “text/plain”;
        root /var/www/letsencrypt;
}

#b.  Make a Directory for ACME Challenges by letsencrypt

1st step: run below command
mkdir /var/www/letsencrypt;
2nd step : add permissions to nginx user.
sudo chown www-data:www-data /var/www/letsencrypt

#C Including Snippets.conf in  nginx.conf or Sererblock

If you want to use the code  / ssl in one website use it directly on website block.
if multiple websites include in nginx.conf
include /etc/nginx/snippets/letsencrypt.conf;
So the small piece of included in conf file.

#4 Automatically issuing Letsencrypt SSL Certificates with nginx Plugin

 

a. Run Below COmmand It will list all all Domains Available in the Server

IMP auto

sudo certbot –nginx

sudo certbot --nginx

 

//auto configuration by letsencrypt to server block

sudo certbot –nginx certonly

// need to add config files manually

NOTE: turnoff cloudflare DNS while renewing or issuing certificate with dns

b. Select the Number of Domains  , multiple or single (Separated by comma or Space) then hit enter

 

Letsencrypt

automatically Adds SSL Configuration in to Website Server blocks.

 

Renewing SSL Certificate

renewal by default automatic

To renew all domains

sudo certbot renew

To view all domains for renewals

sudo certbot renew –dry-run

renew single Domain

certbot renew –cert-name Domain.com

 

Renewing letsencrypt with cloudflare DNS

 

Cloudflare should be turnoff yellow to grey or enable development mode.

 

Migration of ssl Letsencrypt Certificates Won’t works

i tried 2-3 times, by Copying /etc/letsencrypt/Live / Certificates

but it won’t works.

change email letsencrypt

certbot update_account –email yourname+1@example.com

 

Uninstalling Deleting Letsencrypt ssl

Manually by removing

 

or Cert bot command

 

after the command you have to manually remove the code in server block.

 

listen 443 ssl http2;
ssl_certificate /etc/letsencrypt/live/raazkumar.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/raazkumar.com/privkey.pem;
ssl_trusted_certificate /etc/letsencrypt/live/raazkumar.com/fullchain.pem;

 

Configuring with Cloudflare

FIx error redirected many times
Cloudflare SSL  Full Strict
Change Domain url in database https not http.
In wordpress login to phpmyadmin update in url in wp-options table. or use wp-config.php
to define(‘FORCE_SSL_ADMIN’, true);
