keepalived 不绑定 VIP

  • 772

我试图让keepalived在2个debian jessie VM之间工作。

我已定义主机将 VIP 地址绑定到 172.128.28.6，如下所示：

global_defs {
        lvs_id tom_lvs
}

vrrp_instace tom_lvs {
        state MASTER
        interface eth1
    virtual_router_id 1
    priority 100
        authentication {
                auth_type PASS
                auth_pass 1234
        }

    advert_int 1
    virtual_ipaddress {
        172.28.128.6
    }

        virtual_server 172.28.128.6 3000 {
                delay_loop 10
                lb_algo wlc
                lb_kind DR
                protocol TCP
                persistence_timeout 1800
                sorry_server 172.28.128.3 3000
                real_server 172.28.128.4 3000 {
                        weight 1
                        HTTP_GET {
                                url {
                                        path /index.html
                                }
                        }
                }
        }
}

但是，当我运行时，ip addr我没有看到附加到 eth3 的第二个 IP：

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 08:00:27:f6:86:bf brd ff:ff:ff:ff:ff:ff
    inet 10.0.2.15/24 brd 10.0.2.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::a00:27ff:fef6:86bf/64 scope link 
       valid_lft forever preferred_lft forever
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 08:00:27:05:a5:a1 brd ff:ff:ff:ff:ff:ff
    inet 172.28.128.4/24 brd 172.28.128.255 scope global eth1
       valid_lft forever preferred_lft forever
    inet6 fe80::a00:27ff:fe05:a5a1/64 scope link 
       valid_lft forever preferred_lft forever

我显然在这里遗漏了一些东西，但我已经在这里呆了 2 天了，但仍然没有找到它。

如果完全相关，机器正在使用 vagrant 和 virtual-box 运行，两者都定义为从 dhcp 获取它们的地址，它们的 IP 是 /24 子网上的 172.128.28.4 和 172.128.28.3。

这是输出grep Keepalived /var/log/messages：

    如果您复制/粘贴了配置文件，我注意到您的配置中有错字。除此之外，一切似乎都很好。

    您需要修复 VRRP 实例定义为：

    vrrp_instance tom_lvs {

    您错过了关键字中的第二个n字母。vrrp_instance修复配置并重新启动 keepalived 后，您应该会看到类似于以下内容的日志行：

    Keepalived_vrrp[15607]: VRRP_Instance(tom_lvs) Transition to MASTER STATE
Keepalived_vrrp[15607]: VRRP_Instance(tom_lvs) Entering MASTER STATE
