Re: redirect to https

Try this:

upstream elasticsearch {
server 10.X.X.X:9400;
keepalive 10;
}

server {
listen 9200;
return 301 https://$host:9400$request_uri;
}

server {
listen 9400 ssl;
ssl_certificate /etc/pki/tls/certs/validcert.crt;
ssl_certificate_key /etc/pki/tls/private/validcert.key;

location / {
auth_basic "Protected Elasticsearch";
auth_basic_user_file /etc/nginx/htpasswd.users;

proxy_pass http://elasticsearch;
proxy_redirect off;
proxy_buffering off;

proxy_http_version 1.1;
proxy_set_header Connection "Keep-Alive";
proxy_set_header Proxy-Connection "Keep-Alive";
}
}


The SSL certificate and key paths are specified. location / block handles the proxying to the upstream Elasticsearch server, as before.

I Hope this help you.
