haproxy http 重定向 https

对于http端口：80，https端口：443

frontend app
    bind *:80
    bind :443 ssl crt /etc/haproxy/server.pem no-sslv3
    mode http
    option httplog
    option forwardfor
    rspidel ^Server.*
    redirect scheme https if !{ ssl_fc }
    default_backend app

backend app
    mode http
    option httpchk HEAD /
    server app01 server1:3000 check inter 2000 rise 2 fall 5

对于http、https端口不为80、443时，以上的方法就行不通了，得使用下面的方法

frontend app
    bind *:8080
    bind :8443 ssl crt /etc/haproxy/server.pem no-sslv3
    mode http
    option httplog
    option forwardfor
    rspidel ^Server.*
    http-request redirect code 301 location https://www.haxi.cc:8443%[capture.req.uri] if !{ ssl_fc }
    default_backend app

backend app
    mode http
    option httpchk HEAD /
    server app01 server1:3000 check inter 2000 rise 2 fall 5
