CLUVFY工具的安裝過程是怎么樣的

本篇文章為大家展示了CLUVFY工具的安裝過程是怎么樣的，內容簡明扼要并且容易理解，絕對能使你眼前一亮，通過這篇文章的詳細介紹希望你能有所收獲。

如果安裝過10g以后的RAC環境，應該對這個工具并不陌生。在安裝Cluster和Database之前通常會執行runcluvfy.sh腳本來檢查當前系統是否滿足安裝條件。

介紹comp相關選項。

在安裝RAC時，由于cluvfy工具還沒有被安裝，而runcluvfy.sh將cluvfy工具的功能在shell中實現，并和安裝盤一起提供，使得用戶在數據庫和CLUSTER安裝之前就可以利用這個工具的功能。

這個工具的主要作用就是驗證系統是否滿足安裝的條件。

這個工具擁有眾多的選項，因此不可能也沒有必要詳細的描述所有的選項，如果從大類上分，這個工具可以分成兩個大類選項：comp用來驗證組件的功能；stage用來驗證部署功能。

可以通過comp –list來列出所有cluvfy工具支持驗證的組件：

bash-2.03$ cluvfy comp -list

USAGE:
cluvfy comp  <component-name> <component-specific options>  [-verbose]

Valid components are:
        nodereach : checks reachability between nodes
        nodecon   : checks node connectivity
        ssa       : checks shared storage accessibility
        space     : checks space availability
        sys       : checks minimum system requirements
        clu       : checks cluster integrity
        clumgr    : checks cluster manager integrity
        ocr       : checks OCR integrity
        crs       : checks CRS integrity
        nodeapp   : checks node applications existence
        admprv    : checks administrative privileges
        peer      : compares properties with peers

其中nodereach、nodecon和sys等組件都是安裝Cluster環境必不可少的檢查選項：

bash-2.03$ cluvfy comp nodereach -n racnode1,racnode2        

Verifying node reachability

Checking node reachability...
Node reachability check passed from node "racnode2".

Verification of node reachability was successful.

其中-n選項中指定節點列表，在節點列表中的逗號前后都不能包括空格，否則會報錯。

bash-2.03$ cluvfy comp nodereach -n racnode1,racnode2 -verbose

Verifying node reachability

Checking node reachability...

Check: Node reachability from node "racnode2"
  Destination Node                      Reachable?             
  ------------------------------------  ------------------------
  racnode1                              yes                    
  racnode2                              yes                    
Result: Node reachability check passed from node "racnode2".

Verification of node reachability was successful.

使用-verbose會得到更加詳細的信息。

bash-2.03$ cluvfy comp nodecon -n racnode1,racnode2 -verbose

Verifying node connectivity

Checking node connectivity...

其中導致監測失敗的原因是Oracle的bug，Oracle認為172.25開頭的IP地址無法作為PUBLIC地址，這個在以前安裝RAC的時候提到過很多次了。
