如何为多个SSL证书配置HAProxy

Question

我需要用两个不同的SSL证书配置HAProxy。

1. www.example.com
2. api.example.com

现在，我从一篇关于服务器故障( 在Haproxy中配置多个SSL证书 )的文章中了解了如何使用2个证书，但是服务器继续使用这两个域提到的第一个证书。

配置：

frontend apache-https
    bind 192.168.56.150:443 ssl crt /certs/crt1.pem crt /certs/cert2.pem
    reqadd X-Forwarded-Proto:\ https
    default_backend apache-http

backend apache-http
    redirect scheme https if { hdr(Host) -i www.example.com } !{ ssl_fc }
    redirect scheme https if { hdr(Host) -i api.example.com } !{ ssl_fc }
    ...

如何根据URL告诉HAProxy要使用哪个证书？

完整配置：

global
    log /dev/log    local0
    log /dev/log    local1 notice
    chroot /var/lib/haproxy
    stats socket /run/haproxy/admin.sock mode 660 level admin
    stats timeout 30s
    user haproxy
    group haproxy
    daemon

    # Default SSL material locations
    ca-base /etc/ssl/certs
    crt-base /etc/ssl/private

    ssl-default-bind-ciphers ECDH+AESGCM:DH+AESGCM:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:ECDH+3DES:DH+3DES:RSA+AESGCM:RSA+AES:RSA+3DES:!aNULL:!MD5:!DSS
    ssl-default-bind-options no-sslv3
    tune.ssl.default-dh-param 2048 // better with 2048 but more processor intensive

defaults
        log     global
        mode    http
        option tcplog
        option  dontlognull
        timeout connect 5000
        timeout client  50000
        timeout server  50000

frontend apache-http
        bind 0.0.0.0:80
        mode http
        option http-server-close                # needed for forwardfor
        option forwardfor                       # forward IP Address of client
        reqadd X-Forwarded-Proto:\ http
        default_backend apache-http
        stats enable

frontend apache-https
        bind 0.0.0.0:443 ssl crt cer1.pem cert2.pem
        reqadd X-Forwarded-Proto:\ https
        default_backend apache-http

backend apache-http
        redirect scheme https if { hdr(Host) -i db.example.com } !{ ssl_fc }
        redirect scheme https if { hdr(Host) -i api2.example.com } !{ ssl_fc }
        balance roundrobin
        cookie SERVERID insert indirect nocache
        server www-1 10.0.0.101:80 cookie S1 check
        server www-2 10.0.0.102:80 cookie S2 check
        server www-3 10.0.0.103:80 cookie S3 check

您是如何测试哪一个证书是哈代显示的？如果您使用的是openssl s_client，请注意，它需要一个额外的参数(-servername api.domain.com)，以便发送包含代理的SNI信息，以决定显示哪个证书。
