HTTPS on NGINX server running wordpress - wordpress

Question

I am trying to implement HTTPS on a site ased on nginx server, Now even with the below config it only opens HTTP site
My server config for nginx server is like this
server {
listen 443 ssl http2;
ssl_certificate /etc/letsencrypt/live/mydomain.in/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/mydomain.in/privkey.pem;
server_name mydomain.in www.mydomain.in;
rewrite ^(.*) http://$server_name$1 permanent;
}
server {
server_name mydomain.in www.mydomain.in;
access_log /var/log/nginx/mydomain.in.access.log rt_cache_redis;
error_log /var/log/nginx/mydomain.in.error.log;
root /var/www/mydomain.in/htdocs;
index index.php index.html index.htm;
include common/redis-php7.conf;
include common/wpcommon-php7.conf;
include common/locations-php7.conf;
include /var/www/mydomain.in/conf/nginx/*.conf;
}
The server does not serve HTTPS Requests i.e even if i specifically put https in browser it still takes me back to http site. I am not able to diagnose if its nginx or wordpress which is at fault ?
Note : the traffic is routed through cloudflare dns and certificate is
switch off in cloudflare so that it doesn't interfere. I am Relatively new to nginx

Well below is the basic idea.
server {
server_name mydomain.in www.mydomain.in;
listen 80;
location / {
return 301 https://mydomain.in$request_uri;
}
}
server {
listen 443 ssl http2;
ssl_certificate /etc/letsencrypt/live/mydomain.in/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/mydomain.in/privkey.pem;
server_name mydomain.in www.mydomain.in;
access_log /var/log/nginx/mydomain.in.access.log rt_cache_redis;
error_log /var/log/nginx/mydomain.in.error.log;
root /var/www/mydomain.in/htdocs;
index index.php index.html index.htm;
include common/redis-php7.conf;
include common/wpcommon-php7.conf;
include common/locations-php7.conf;
include /var/www/mydomain.in/conf/nginx/*.conf;
}
The top server block listens on port 80 (http). It has one location block which does a return 301. return is preferred over rewrites in most cases. I also put it into a location block because you have a letsencrypt ssl cert which might require another location ^~ /.well-known { block to help handle that.
The second server block listens on port 443 (https). It has the SSL certs and includes the information exposed previously for as the http server block.
This setup will handle redirecting from http on either mydomain.in or www.mydomain.in to https mydomain.in. On https both mydomain.in and www.mydomain.in will receive SSL requests.
If you want it to redirect to a primary https domain you can add another server block for the secondary(ies) like so.
server {
server_name www.mydomain.in;
listen 443 ssl http2;
ssl_certificate /etc/letsencrypt/live/mydomain.in/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/mydomain.in/privkey.pem;
location / {
return 301 https://mydomain.in$request_uri;
}
}
Of course, this means you would have to change the second server block to remove the secondary(ies) domain names.
Also while testing you might want to change the 301s to 302s so that if you misconfigure the first time that it not be stuck in the browser cache. After you get everything to a good state then change back to 301s.
