nginx - Redirect HTTP to HTTPS with ldirectord/LVS

itemprop="text">

We're using LVS for load balancing and
want to do a 301 redirect for http://example.com to rel="nofollow
noreferrer">https://example.com

LVS
is enabling https without issue, but the http real servers are not being added to the
pool (weight of 0).

Does LVS not follow 301
redirects? If not, how do I configure ldirectord to send all HTTP traffic to
HTTPS?

Here is the nginx
config:

server
            {
 listen 80;
 server_name example.com;
 return 301
            https://example.com$request_uri;
}

server {

            listen 443;
 ssl on;

 ssl_certificate
            server.crt;
 ssl_certificate_key server.key;
 server_name
            example.com;

# more
            here

}

And
ldirectord.cf looks like
this:

virtual=VIP:80

            fallback=127.0.0.1:80
 real=10.0.0.7:80 masq 5
 real=10.0.0.8:80
            masq 5
 service=http
 request="lvs.htm"

            receive="lvs"
 virtualhost=example.com

            scheduler=wlc

 protocol=tcp

            checktype=negotiate

virtual=VIP:443

            fallback=127.0.0.1:443
 real=10.0.0.7:443 masq 5
 real=10.0.0.8:443
            masq 5
 service=https
 request="lvs.htm"

            receive="lvs"

 virtualhost=example.com

            scheduler=wlc
 protocol=tcp

            checktype=negotiate

I
also tried setting my VIP to port 80 and my RIP ports to 443 which resulted in the
servers being added to the pool, but nginx then returns a 400 "The plain HTTP request
was sent to HTTPS port" error.

I was
making this harder than it needed to be.

I modified my nginx.conf as
so:

server {
 listen
            80;
 server_name example.com;

 root
            /var/www;

 location = /lvs.htm {
 #do
            nothing

 }

 location / {
 return 301
            https://example.com$request_uri;

            }
}

lvs.htm
resides in /var/www so the location is matched, searching stops and lvs.htm is served
with a 200 response code. LVS adds the server to the pool and when it is hit, nginx
correctly redirects to https with a 301.
