nano /opt/bitnami/nginx/conf/server_blocks/wordpress-https-server-block.conf
Bitnami configuration

Change with the www or non-www version of your website. That means Bitnami WordPress will redirect HTTP to HTTPS nginx. Now we point all traffic to one naked domain(in our case). And provide a path for the SSL certificate. Edit server 443, add the following lines.

ssl_certificate      "/opt/bitnami/letsencrypt/certificates/";
ssl_certificate_key  "/opt/bitnami/letsencrypt/certificates/";
#       ssl_certificate      server.crt;

define('WP_SITEURL', '');
define('WP_HOME', '');

replace with 

define('WP_SITEURL', '');
define('WP_HOME', '');

Now press ctrl+X, then Y, and press Enter to save the changes.

  1. Hello, Kumar!
    When I go to the step, “Configure WordPress for SSL certificate.”
    and type “nano /opt/bitnami/wordpress/htdocs/wp-config.php”
    it says “[ Directory ‘/opt/bitnami/wordpress/htdocs’ does not exist ]”
    Could you help me to solve this problem?

    1. I have already found the solution!
      We should type “nano /opt/bitnami/wordpress/wp-config.php” now
      and add the following script in the file
      “define(‘WP_SITEURL’, ‘’);
      define(‘WP_HOME’, ‘’);”

      My website finally has SSL, thanks for your detailed article!

  2. Hi Ashok,
    Thank you for your information. This way was really helpful for me. However, I am having trouble making the auto-renew feature.
    Is there a way to make an auto-renew for SSL certification in the WordPress Nginx stack?
