SSL I have bought an Comodo Positive SSL from Namecheap. How to install and use it in Centminmod

Method 1 is how what you're looking for. Though Method 3 is probably easiest to just use free letsencrypt SSL certificates.

There's generally 3 ways of setting up HTTPS SSL certificate for Centmin Mod Nginx HTTP/2 based HTTPS

Method 1. The traditional way via centmin.sh menu option 2, 22 and selecting yes to self-signed ssl certificates first. Then converting the self-signed ssl certificate to paid or free (Letsencrypt) web browser trusted SSL certificates outlined at How to switch self-signed SSL certificate to paid SSL certificate ? You would still need to follow the same steps outlined at Nginx SPDY SSL Configuration for obtaining and purchasing the paid SSL certificate and most important part is the concatenation of the SSL provider provided filesto create the mentioned /usr/local/nginx/conf/ssl/domaincom/ssl-unified.crt and /usr/local/nginx/conf/ssl/domaincom/ssl-trusted.crtfiles referenced in your Nginx SSL vhost config file.

You may need to also decide if you want to enable HTTP to HTTPS redirect outlined at How to force redirect from HTTP:// to HTTPS:// ?

If you didn't answer yes at time of initial nginx vhost creation to self-signed ssl certificates, you can manually setup the self-signed ssl certificate via the vhost generator by checking self-signed ssl box and enter a domain name. This will outline instructions for manually creating and setting up self-signed ssl certificate and nginx vhost settings. Then for web browser trusted ssl certificates you switch follow - How to switch self-signed SSL certificate to paid SSL certificate ?.

Method 2. Using and testing Centmin Mod 123.09beta01's new addons/acmetool.sh addon which is still in beta testing only for integrating Letsencrypt SSL certificates. And has both auto and manual methods.

Method 3. Fully manual method for free Letsencrypt SSL certificates.

• For existing non-HTTPS Nginx vhost sites migration to HTTPS as outlined at Migrating Existing Nginx Vhost From HTTP to HTTP/2 based HTTPS With Letsencrypt SSL Certificates
• For brand new Nginx vhosts not yet created on server use this guide Using Centmin Mod acmetool.sh addon for Nginx HTTP/2 based HTTPS with free Letsencrypt SSL certificates

Note:

• For wordpress auto installer, you actually need a read method 2 to enable LETSENCRYPT_DETECT='y' then run centmin.sh menu option 22 which will detect letsencrypt support and display the additional letsencrypt prompts required to issue free letsencrypt ssl certificates for wordpress auto installer

 

i think that means previous paid SSL certs they provided themselves i.e. to prevent folks from using promo ssl to renew an existing promo ssl domain over time. Nothing to do with letsencrypt ssl pre-existing

 

yes method 1 above at SSL - I have bought an Comodo Positive SSL from Namecheap. How to install and use it in Centminmod outlines csr generation too

 

Where are you verifying that SSL cert isn't showing up ? Run your HTTPS domain site through SSLLabs tester at SSL Server Test (Powered by Qualys SSL Labs)

If you have cloudflare in front of centmin mod nginx, then cloudflare ssl cert is show as expected and not your comodo ssl cert on nginx

 

incorrect paths for

Code (Text):

ssl_dhparam /usr/local/nginx/conf/ssl/zepperin/dhparam.pem;
  ssl_certificate      /usr/local/nginx/conf/ssl/zepperin/zepper_in.crt;
  ssl_certificate_key  /usr/local/nginx/conf/ssl/zepperin/zepper_in.key;
 ssl_trusted_certificate /usr/local/nginx/conf/ssl/zepperin/ssl-trusted.crt;

from method 1 linked instructions at Nginx HTTP/2 & SPDY SSL Configuration - CentminMod.com LEMP Nginx web stack for CentOS ssl_certificate needs to point to ssl-unified.crt you created.

Code (Text):

ssl_dhparam /usr/local/nginx/conf/ssl/zepperin/dhparam.pem;
  ssl_certificate      /usr/local/nginx/conf/ssl/zepperin/ssl-unified.crt;

run nginx config test

nginx -t
