lvs-tun节点未连接

Question

我正在使用隧道建立一个LVS集群。目标是有两个指导服务器(在不同的数据中心中)和一个真正的服务器(目前，将在负载平衡中添加更多)。通过端口80、443和8080访问真正的服务器。

我已经成功地配置了我的主要主管，它运行得很好，所有的端口都是开放的，数据流动得很好。

但是，备份指导只能连接到端口443上的真正服务器。下面是我在/var/log/messages中获得的输出：

Oct 27 12:25:20 vps4252 pulse[2819]: STARTING PULSE AS MASTER

Oct 27 12:25:43 vps4252 pulse[2823]: gratuitous lvs arps finished

(忽略缺少的端口80行，我在测试时禁用了它)

保姆进程似乎只能连接到端口443上的真正服务器。然而，对于netcat或curl，我在其他两个端口上得到了正确的响应。

下面是我的lvs.cf (作为一个服务器)：

serial_no = 36
primary = 103.13.yyy.yyy
service = lvs
backup = 0.0.0.0
heartbeat = 1
heartbeat_port = 539
keepalive = 6
deadtime = 18
network = tunnel
debug_level = NONE
virtual http {
    active = 1
    address = 103.13.xxx.xxx eth0:1
    vip_nmask = 255.255.255.255
    port = 80
    send = "GET / HTTP/1.0\r\n\r\n"
    expect = "HTTP"
    use_regex = 0
    load_monitor = none
    scheduler = rr
    protocol = tcp
    timeout = 6
    reentry = 15
    quiesce_server = 0
    #Define nodes
    server node1 {
        address = 103.29.zzz.zzz
        active = 1
        port = 80
        weight = 1
    }
}
virtual https {
    active = 1
    address = 103.13.xxx.xxx eth0:1
    vip_nmask = 255.255.255.255
    port = 443
    send = "GET / HTTP/1.0\r\n\r\n"
    expect = "HTTP"
    use_regex = 0
    load_monitor = none
    scheduler = rr
    protocol = tcp
    timeout = 6
    reentry = 15
    quiesce_server = 0
    #Define nodes
    server node1 {
        address = 103.29.zzz.zzz
        active = 1
        port = 443
        weight = 1
    }
}
virtual http_8080 {
    active = 1
    address = 103.13.xxx.xxx eth0:1
    vip_nmask = 255.255.255.255
    port = 8080
    send = "GET / HTTP/1.0\r\n\r\n"
    expect = "HTTP"
    use_regex = 1
    protocol = tcp
    #Define nodes
    server node1 {
        address = 103.29.zzz.zzz
        active = 1
        port = 8080
        weight = 1
    }
}

实际服务器上的隧道已正确设置(毕竟，端口443正在工作)

所以我很困惑..。是否有办法强迫节点处于活动状态，即使保姆找不到它？

解决这个问题的方法是创建一个bash脚本来平平真正的服务器，并从lvs配置文件中调用它。
