无法使用keepalived和VRRP设置浮动IP

Question

我有一台ubuntu机器托管着两个虚拟机，每个虚拟机都运行一个应用程序，我需要为它们提供高可用性，所以我使用keepalived和VRRP实现了一个浮动IP，但我无法使用主机上的虚拟IP ping主虚拟机，它显示目标主机无法到达。

用于VM1的keepalived.conf：

vrrp_instance VI_1 { 
    interface enp1s0 
    state MASTER                  #BACKUP here for VM2
    virtual_router_id 51 
    priority 200                  #100 in case of VM2
    advert_int 2 
    authentication { 
        auth_type PASS
        auth_pass monkey 
    } 
    virtual_ipaddress { 
        192.168.122.150/24
    }
}

当我启动keepalived服务时，它显示以下消息：

Dec 19 14:31:37 secondaryvm Keepalived_vrrp[1419]: Unknown keyword '}'

Answer 1

回答有点晚了，但我自己也遇到了类似的问题。我一直收到一个错误，说"vrrp_track_process“是一个未知的关键字，即使在一个虚拟机上工作，而不是在其他虚拟机上工作。在查看"man keepalived.conf“时，我注意到一个虚拟机的文档中有"vrrp_track_process”，而另一个则没有。因此，需要更新包/ repo。很可能安装的包的当前版本不支持使用的关键字。
