Adding new nginx server block + issuing Lets Encrypt SSL certificate for it

This guide is useful if you're using HostBill Multi-Brand module on HostBill Enterprise install. This guide assumes you're familiar with linux file editors (like vim or nano).

1. Adding new vhost (server block) to nginx:
   
   Make a copy /etc/nginx/conf.d/main.conf file:

   cp /etc/nginx/conf.d/main.conf /etc/nginx/conf.d/yourbrand.com.conf

   Update  server_name block in /etc/nginx/conf.d/yourbrand.com.conf file:
   
   

   Contents of /etc/nginx/conf.d/yourbrand.com.conf

   include /etc/nginx/upstreams/*.conf;
   
   server {
       listen 80;
       server_tokens off;
       return 301 https://$host$request_uri;
   
   }
   
   server {
       listen 443 ssl;
       server_name yourbrand.com www.yourbrand.com;
       server_tokens off;
   
       charset                     utf-8;
       sendfile                    on;
       tcp_nopush                  on;
       tcp_nodelay                 off;
       reset_timedout_connection   on;
   
       location ~* ^.+\.(jpg|gif|png|css|js|swf|ico)$ {
           access_log      off;
           log_not_found   off;
           expires         1y;
       }
   
       include /etc/nginx/ssl.conf;
       include /etc/nginx/locations/*.conf;
   
   }
       

2. Issue a Let's Encrypt certificate using certbot command for your additional brand/domain:

   certbot --nginx -d yourbrand.com

3. Reload nginx to apply new site block + ssl certificate:

   systemctl reload nginx
