lvs-tun 节点未连接

我正在使用隧道设置 LVS 集群。目标是拥有两台控制器服务器（位于不同的数据中心）和一台真实服务器（目前，稍后将在负载平衡中添加更多服务器）。真实服务器通过端口 80、443 和 8080 访问

我已经成功配置了我的主机，它运行良好，所有端口都打开，数据流通顺畅

但是，备份控制器只能通过端口 443 连接到真实服务器。这是我在 /var/log/messages 中得到的输出：

Oct 27 12:25:20 vps4252 pulse[2819]: STARTING PULSE AS MASTER
Oct 27 12:25:38 vps4252 pulse[2819]: partner dead: activating lvs

Oct 27 12:25:38 vps4252 nanny[2833]: starting LVS client monitor for 103.13.xxx.xxx:8080 -> 103.29.zzz.zzz:8080

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

（忽略缺失的 80 端口行，我当时为了测试而禁用了它）

看起来 Nanny 进程只能通过端口 443 连接到真实服务器。但是，使用 netcat 或 curl，我可以通过其他 2 个端口获得正确的响应。

这是我的 lvs.cf（作为单个服务器）：

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
    }
}

真实服务器上的隧道已正确设置（毕竟 443 端口正在运行）

所以我很困惑...有没有办法强制节点处于活动状态，即使保姆没有找到它？

答案1

这个问题通过创建一个 bash 脚本来 ping 真实服务器，并从 lvs 配置文件中调用它来解决。
