3 安裝Grid Infrastructure
從此步驟開始，我們正式安裝Grid軟件：
① 以grid用戶登錄圖形界面，執行/home/grid/grid/runInstaller,進入OUI的圖形安裝界面：
② 進入OUI安裝界面後，選擇第3項，跳過軟件更新，Next：
③ 選擇集羣的Grid Infrastructure，Next：
.png)
④ 選擇 advanced Installation，Next：
⑤ 語言選擇默認，English，Next：
⑥ 去掉Configure GNS選項，按照之前2.1節中的表格輸入Cluster Name:scan-cluster,SCAN Name：scan-cluster.localdomain。Next：
⑦ 單擊Add，添加第2個節點，Next：
⑧ 確認網絡接口，Next：
⑨ 選擇ASM，作爲存儲，Next：
⑩ 輸入ASM磁盤組名，這裏命名爲GRIDDG，冗餘策略選擇External外部，AU大小選擇默認1M，ASM磁盤選擇VOL1，VOL2。Next：
⑪ 選擇給ASM的SYS、ASMSNMP用戶配置爲相同的口令，並輸入口令，Next：
⑫ 選擇不使用IPMI，Next：
⑬ 給ASM指定不同的組，Next：
⑭ 選擇GRID軟件的安裝路徑，其中ORACLE_BASE,ORACLE_HOME均選擇之前已經配置好的，可參照2.5節中的配置信息。這裏需要注意GRID軟件的ORACLE_HOME不能是ORACLE_BASE的子目錄。
⑮ 選擇默認的Inventory，Next：
⑯ 檢查出現告警，提示在所有節點上缺失cvuqdisk-1.0.9-1軟件包。
可以選擇忽略，直接進入下一步安裝。也可以從grid安裝文件的rpm目錄下獲取該RPM包，然後進行安裝。

在所有節點上安裝完cvuqdisk-1.0.9-1軟件後，重新執行預檢查，不再有警告信息。
⑰ 進入安裝GRID安裝之前的概要信息，Install進行安裝：
⑱ 根據提示以root用戶分別在兩個節點上執行腳本：
執行/u01/app/oraInventory/orainstRoot.sh腳本：
