Nginx SSL Configuration
Let’s say we have an Nginx virtual host like following
|
1 2 3 4 5 6 |
server { listen 80; root /var/www/html; server_name serverok.in; index index.htm index.html; } |
To make it SSL enabled, add the following to the server entry.
|
1 2 3 4 |
listen 443 ssl http2; ssl_certificate /etc/ssl/serverok.crt; ssl_certificate_key /etc/ssl/serverok.key; ssl_client_certificate /etc/ssl/serverok.ca; |
ssl_client_certificate introduced in Nginx version 1.19.4. If you are using an older version, add your ca-bundle after SSL certificate.
Example
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
server { listen 80; root /var/www/html; server_name serverok.in; index index.htm index.html; listen 443 ssl http2; ssl_certificate /etc/ssl/serverok.crt; ssl_certificate_key /etc/ssl/serverok.key; ssl_client_certificate /etc/ssl/serverok.ca; location / { try_files $uri/index.html $uri.html $uri; } } |
SSL protocols

dhparam
Create
|
1 |
openssl dhparam -out /etc/ssl/dhparam.pem 2048 |
In your nginx config, add
|
1 |
ssl_dhparam /etc/ssl/dhparam.pem; |
Redirect Traffic to SSL
|
1 2 3 4 5 |
server { listen 80; server_name www.serverok.in serverok.in; return 301 https://serverok.in$request_uri; } |
If you don’t want to redirect SSL verification requests to HTTPS, use
|
1 2 3 4 5 6 7 8 9 10 11 12 |
server { listen 80; server_name DOMAIN_NAME; location ~ ^/.well-known/ { allow all; autoindex on; root /var/www/html; } location / { return 301 https://DOMAIN_NAME$request_uri; } } |
