HAProxy 检查端口 443

是否可以让 HAProxy 对 SSL / 端口 443 端点进行健康检查？

以下check port 443配置未通过健康检查

HAProxy 配置如下

global
    log         127.0.0.1 local2

    chroot      /var/lib/haproxy
    pidfile     /var/run/haproxy.pid
    maxconn     50000
    user        haproxy
    group       haproxy
    daemon

    # turn on stats unix socket
    stats socket /var/lib/haproxy/stats

defaults
    mode                    tcp
    log                     global
    option                  dontlognull
    retries                 3
    timeout queue           1m
    timeout connect         10s
    timeout client          1m
    timeout server          1m
    timeout check           5s
    maxconn                 15000

    option ssl-hello-chk
    balance roundrobin
    option httpchk GET /heartbeat.php HTTP/1.1\r\nHost:\ admin.example.com
    server admin-no-check-test     ec2-XXX-XXX-XXX-150.eu-west-1.compute.amazonaws.com:443 maxconn 5000
    server admin-150-checkport-80  ec2-XXX-XXX-XXX-150.eu-west-1.compute.amazonaws.com:443 check port 80 maxconn 5000
    server admin-150-checkport-443 ec2-XXX-XXX-XXX-150.eu-west-1.compute.amazonaws.com:443 check port 443 maxconn 5000

我认为option ssl-hello-chk和option httpchk是两种不同的检查，但 HAProxy 只允许您一次使用其中一种。您应该选择ssl-hello-chk仅检查 SSL 是否存在，或使用httpchk检查特定 URI，但不能同时使用两者。
