如何在 Linux 集群上設置虛擬 IP？

我在設置虛擬 IP 和 Linux (Ubuntu) 集群時遇到了一些問題，希望有人能提供幫助。這是我嘗試設置的第一個節點集群，我沒有找到很多關於這個問題的資源。

我正在閱讀本指南以在 Ubuntu 上設置 DRBD/虛擬 IP：https ://wiki.edubuntu.org/ClusterStack/Natty#HA_Virtual_IP_Address

但是我在設置虛擬 IP 時遇到了一些重大問題。我已經設置了 DRBD，它可以毫無問題地同步和載入。但是當我嘗試添加虛擬 IP 時，我收到以下錯誤消息

pengine: [843]: info: native_color: Resource virtual_ip cannot run anywhere

這是我的 CRM 配置：

node EOA-MAIL-IB-1
node EOA-MAIL-IB-2
primitive drbd_eoa ocf:linbit:drbd \
   params drbd_resource="eoa-ib" \
   op monitor interval="15s"
primitive fs_drbd ocf:heartbeat:Filesystem \
   params device="/dev/drbd0" directory="/mnt" fstype="ext4" \
   meta target-role="Stopped"
primitive virtual_ip ocf:heartbeat:IPaddr2 \
   params ip="192.168.1.254" nic="eth1" \
   op monitor interval="30s"
group res_group fs_drbd virtual_ip
ms ms_drbd drbd_eoa \
   meta master-max="1" master-node-max="1" clone-max="2" clone-node-max="1$
colocation mnt_on_master inf: res_group ms_drbd:Master
order mount_after_drbd inf: ms_drbd:promote res_group:start
property $id="cib-bootstrap-options" \
   dc-version="1.0.8-042548a451fce8400660f6031f4da6f0223dd5dd" \
   cluster-infrastructure="openais" \
   expected-quorum-votes="2" \
   stonith-enabled="false" \
   no-quorum-policy="ignore" \
   last-lrm-refresh="1336683121"

這是“crm 資源列表”的輸出：

Master/Slave Set: ms_drbd
Masters: [ EOA-MAIL-IB-1 ]
Slaves: [ EOA-MAIL-IB-2 ]
Resource Group: res_group
fs_drbd    (ocf::heartbeat:Filesystem) Stopped
virtual_ip (ocf::heartbeat:IPaddr2) Stopped

我在兩台伺服器上都安裝了兩個 NICS。

任何幫助將不勝感激。

謝謝！

原來 CRM 配置文件存在配置問題，請看圖。:)

以下是遇到此類問題的其他任何人的更新/正確配置文件：
