haproxy多个后端端口

Question

我有一个HA代理配置，在后端有三个应用服务器集群。后端服务器使用端口http-＆gt; 80，socket.io-＆gt; 3000和redis-＆gt; 6379

所以我创建了以下后端和前端。对于第一个应用程序，我添加了socket.io en redis。但不是第二个。不确定这样做是否是最佳方式。

frontend http-in
    bind *:80 name port80
    mode http

    # Define hosts
    acl host_appl3 hdr(host) -i im.test.com
    acl host_appl4 hdr(host) -i appl4.test.com
    acl websocket_appl3 hdr(Upgrade) -i Websocket

    # figure out which one to use
    use_backend appl3_cluster if host_appl3
    use_backend appl4_cluster if host_appl4
    use_backend appl3_websocket if appl3_websocket

frontend redis
    bind *:6379 name port6379

    #define hosts
    acl redis_appl3 hdr(host) -i im.test.com

    #figure out which one to use
    use_backend appl3_redis if redis_appl3

backend appl3_cluster
    mode http
    balance leastconn
    option httpclose
    option forwardfor
    cookie JSESSIONID prefix
    # private address
    server appl3node1_http 10.146.94.99:80 cookie A check
    # private address
    # server appl3node2_http x.x.x.x cookie A check

backend appl3_websocket
    mode http
    option forwardfor
    reqadd x-forwarded-proto:\ http
    server appl3node1_ws 10.146.94.99:3000 check
    # server appl3node2_ws x.x.x.x:3000 check

backend appl3_redis
    mode tcp
    option tcplog
    option tcp-check
    tcp-check send PING\r\n
    tcp-check expect +PONG
    tcp-check send info\ replication\r\n
    tcp-check expect string role:master
    tcp-check send QUIT\r\n
    tcp-check expect string +OK
    server appl3node1_redis 10.146.94.99:6379 check inter ls
    #server appl3node2_redis x.x.x.x:6379 inter ls

backend appl4_cluster
    balance leastconn
    option httpclose
    cookie JSESSIOID prefix
    # private address
    server node2_http 10.42.71.166:80 cookie A check
etc.....

有人帮助我吗？
