我在 ubuntu 12.10 服务器上安装了 keepalived 包并对其进行了配置，但它后来在系统日志中抱怨必须设置虚拟 ID

保持活动配置

# Define the script used to check if haproxy is still working
vrrp_script chk_haproxy { 
    script "killall -0 haproxy"
    interval 2 
    weight 2 
}
  
# Configuation for the virtual interface
vrrp_instance VI_1 {
    state MASTER        # set this to BACKUP on the other machine

    virtual_router_id 1

    priority 101        # set this to 100 on the other machine

    interface eth0

    # The virtual ip address shared between the two loadbalancers
    virtual_ipaddress {

    }
     
    # Use the script above to check if we should fail over
    track_script {
        chk_haproxy
    }
}

网络配置

auto eth0
iface eth0 inet static
    address 192.168.1.11
    netmask 255.255.255.0 

auto eth0:1
iface eth0:1 inet static
    address 192.168.1.10
    netmask 255.255.255.0

SysLog 输出告诉我必须设置虚拟 ID...在任何文档中都找不到与该错误相关的任何内容

（这还不是一个答案，但是日志文件在评论中太难读取）

再次强调，完全没有问题

我按原样使用 OP keepalived.conf，并且能够启动它而不会出现任何 syslog 错误，无论有没有 eth0:1（192.168.1.10）。

安装 keepalived

apt-get install keepalived

dpkg -l|grep keepalived
ii  keepalived    1:1.2.2-3ubuntu1    Failover and monitoring daemon for LVS clusters

该包中没有keepalive.conf文件，只有一个空/etc/keepalived目录。

系统日志输出似乎不同。

答案2

不确定这是否与日志中显示的错误有关，但您不应该自己在机器上设置 VIP。Keepalived 会处理它。

因此删除eth0:0中的别名/etc/network/interfaces。

答案3

最近遇到了同样的错误消息，我想在这里添加解决方案。在我们的例子中，配置文件的内容是通过 Windows 文本编辑器剪切和粘贴的。虽然文件在 Windows（和 VI）中看起来不错，但使用“less”查看文件时显然存在一些问题。

查看源代码，您可以看到错误消息基本上是配置文件问题的全部内容。错误消息：

1 月 28 日 17:08:02 Test-LB1 Keepalived_vrrp[7027]: VRRP_Instance(VI_1) 必须设置虚拟 ID！

清理文件并使用常规空格后，一切正常。

非空格空格破坏配置
