我第一次設定電腦。我有兩台 CentOS 7 虛擬機，在上面安裝了電腦和 Pacemaker。我定義了一個虛擬IP和Apache HTTP叢集。
兩台虛擬機器的 IP 分別為 192.168.56.121 和 192.168.56.122。 VIP 配置為 192.168.56.199。我可以 ping VIP 並可以在 VIP 上開啟測試index.html。
根據這裡的另一篇文章，我已停止並停用 httpd.service，因為 pcs 管理其操作。與 SELinux 一樣，firewalld 已停用。
我有兩個問題：首先，兩個節點上的 index.html 是一行文本，表示「節點 1」和「節點 2」。多次刷新頁面，我發現只有節點 1 檔案被提供，除非我停止該節點，在這種情況下，節點 2 的檔案被提供。這表示節點處於主備狀態。有什麼辦法讓它成為一個負載平衡器，兩個節點都服務交替請求？
其次，pcs status 顯示資源處於停止狀態，儘管 ping 和 http 正在工作。
這是pcs status顯示的內容：
