Recently I had to install SSL certs and came across concept of Multi Domain (SANs) and it made life so easy. Hence I documented the whole process here in this article
Basically we we put [alt_names] in openssl.cnf:
[ alt_names ]
DNS.1 = example.com
DNS.2 = www.example.com
DNS.3 = api.example.com
And then generate CSR:
openssl req -new -nodes -out example.csr -newkey rsa:2048 -keyout example.key -config openssl.cnf
Link to full Article is here Install Free SSL Certificate on Nginx/HTTPD with Multi-Domain SAN support explain step by step procedure to install certs on Nginx/HTTPD
