2台主機互為備份，Web服務顯示NFS文件系統上的資源。
新增一個Linux6.8的系統作為NFS文件伺服器
目錄：
1、完成HeartBeat基礎配置
2、配置NFS伺服器
3、配置HeartBeat資源管理伺服器使用NFS資源
4、結果測試
1、完成HeartBeat基礎配置
基礎配置這裡就不在敘述了，參考下麵這篇文檔。
HeartBeat基礎配置（實現Web服務雙機熱備）
2、配置NFS伺服器
創建共用文件夾/file/web/
mkdir -p /file/web/ echo "<h1>this is nfs server</h1>" >> /file/web/index.html配置共用文件
vim /etc/exports 添加 /file/web 192.168.0.0/255.255.0.0(ro)NFS服務配置
vim /etc/sysconfig/nfs啟動相應的NFS版本，這裡我們使用4
啟動服務，配置開機自啟
service nfs start chkconfig nfs on檢查共用的文件夾
關閉selinux
如果是臨時測試
setenforce 0如果長期使用
vim /etc/selinux/config
註意：
如果是實際生產環境，建議將selinux開啟，然後乖乖去寫安全規則。
NFS服務配置完畢
3、配置HeartBeat資源管理伺服器使用NFS資源
測試文件掛載
NA1（關閉selinux）
setenforce 0 mkdir -p /mnt/webfile/ mount -t nfs 192.168.94.131:/file/web /mnt/webfile/
掛載沒問題。取消掛載
umount /mnt/webfileNA2（關閉selinux）
setenforce 0
配置heartbeat資源管理器
NA1&NA2關閉heartbeat服務
service heartbeat stop將NFS共用目錄掛載到/var/www/html下
vim /etc/ha.d/haresources 添加 na1.server.com IPaddr::192.168.94.222/24/eth1 Filesystem::192.168.94.131:/file/web::/var/www/html::nfs httpd然後將haresource複製到NA2上。
scp /etc/ha.d/haresources na2:/etc/ha.d/啟動heartbeat服務
service heartbeat start ssh na2 'service heartbeat start'查看日誌
