[Solved] Basic usage of HAProxy

[trumee]

Hi,

I have a nginx server running in my LAN with an ip address of 192.168.1.10. The nginx server is reachable via https on the LAN and has 'lets encrypt' certificates installed. I want to reach this server from the WAN side. I defined the backend for this ip address, but the stats show it as Down with the status  "L7STS/405 in 1ms". If i change the backend port to 80, it does show up as Online.

Any idea how can i make it to work?

My HAProxy config is as follows

global
        maxconn                 1000
        stats socket /tmp/haproxy.socket level admin
        uid                     80
        gid                     80
        nbproc                  1
        chroot                  /tmp/haproxy_chroot
        daemon

listen HAProxyLocalStats
        bind 127.0.0.1:2200 name localstats
        mode http
        stats enable
        stats admin if TRUE
        stats uri /haproxy_stats.php?haproxystats=1
        timeout client 5000
        timeout connect 5000
        timeout server 5000

frontend frontend
        bind                    xx.175.101.zz:443 name xx.175.101.zz:443
        mode                    tcp
        log                     global
        maxconn                 100
        timeout client          30000
        default_backend site1_https_ipvANY

backend site1_https_ipvANY
        mode                    tcp
        log                     global
        timeout connect         30000
        timeout server          30000
        retries                 3
        option                  httpchk OPTIONS /
        server                  mywebsite 192.168.1.10:443 check-ssl check inter 1000  weight 10 verify none

If you get a "405 Method not allowed", then changing the method might help. Try HEAD instead of OPTIONS, or one of the others like GET.

I add the following to nginx.conf and the problem went away.

 location / {

    if ($request_method = OPTIONS ) {
        add_header Access-Control-Allow-Origin "https://cloud.example.com";
        add_header Access-Control-Allow-Methods "GET, OPTIONS";
        add_header Access-Control-Allow-Headers "Authorization";
        add_header Access-Control-Allow-Credentials "true";
        add_header Content-Length 0;
        add_header Content-Type text/plain;
        return 200;
    }
