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(nèi)容簡(jiǎn)明扼要并且容易理解，絕對(duì)能使你眼前一亮，通過這篇文章的詳細(xì)介紹希望你能有所收獲。

如果安裝過10g以后的RAC環(huán)境，應(yīng)該對(duì)這個(gè)工具并不陌生。在安裝Cluster和Database之前通常會(huì)執(zhí)行runcluvfy.sh腳本來檢查當(dāng)前系統(tǒng)是否滿足安裝條件。

介紹comp相關(guān)選項(xiàng)。

在安裝RAC時(shí)，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(shí)現(xiàn)，并和安裝盤一起提供，使得用戶在數(shù)據(jù)庫(kù)和CLUSTER安裝之前就可以利用這個(gè)工具的功能。

這個(gè)工具的主要作用就是驗(yàn)證系統(tǒng)是否滿足安裝的條件。

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

可以通過comp –list來列出所有cluvfy工具支持驗(yàn)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(huán)境必不可少的檢查選項(xiàng)：

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(xiàng)中指定節(jié)點(diǎn)列表，在節(jié)點(diǎn)列表中的逗號(hào)前后都不能包括空格，否則會(huì)報(bào)錯(cuò)。

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?             
  ------------------------------------  ------------------------

  racnode2                              yes                    
Result: Node reachability check passed from node "racnode2".

Verification of node reachability was successful.

使用-verbose會(huì)得到更加詳細(xì)的信息。

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

Verifying node connectivity

Checking node connectivity...

其中導(dǎo)致監(jiān)測(cè)失敗的原因是Oracle的bug，Oracle認(rèn)為172.25開頭的IP地址無法作為PUBLIC地址，這個(gè)在以前安裝RAC的時(shí)候提到過很多次了。

利用cluvfy不僅可以檢查是否滿足安裝要求，還可以驗(yàn)證組件是否工作正常。
