CLUVFY工具的安装过程是怎么样的

本篇文章为大家展示了CLUVFY工具的安装过程是怎么样的，内容简明扼要并且容易理解，绝对能使你眼前一亮，通过这篇文章的详细介绍希望你能有所收获。

如果安装过10g以后的RAC环境，应该对这个工具并不陌生。在安装Cluster和Database之前通常会执行runcluvfy.sh脚本来检查当前系统是否满足安装条件。

介绍comp相关选项。

在安装RAC时，由于cluvfy工具还没有被安装，而runcluvfy.sh将cluvfy工具的功能在shell中实现，并和安装盘一起提供，使得用户在数据库和CLUSTER安装之前就可以利用这个工具的功能。

这个工具的主要作用就是验证系统是否满足安装的条件。

这个工具拥有众多的选项，因此不可能也没有必要详细的描述所有的选项，如果从大类上分，这个工具可以分成两个大类选项：comp用来验证组件的功能；stage用来验证部署功能。

可以通过comp –list来列出所有cluvfy工具支持验证的组件：

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等组件都是安装Cluster环境必不可少的检查选项：

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选项中指定节点列表，在节点列表中的逗号前后都不能包括空格，否则会报错。

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会得到更加详细的信息。

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

Verifying node connectivity

Checking node connectivity...

其中导致监测失败的原因是Oracle的bug，Oracle认为172.25开头的IP地址无法作为PUBLIC地址，这个在以前安装RAC的时候提到过很多次了。
