解决Oracle 19c RAC 安装时节点连接性问题

第二天，联系了服务器管理员在下午得到了修复，虚拟网段的IP失效了，需要重新分配，并且虚拟IP没有网关，所以ping 网关ping 不通。

因为在一节点装了集群软件，所以需要继续清理环境。

准备完成，经过昨天的安装，有些地方容易检查不到，按道理来说，宕机的二节点，出多的地方应该没那么多，上篇提到环境变量ORACLE_HOME基目录、用户、用户组等都出错了，环境变量错了，咱也不知道当时是怎么按上去的，还是当时就故障了没发现。。。。

所以，找了一篇关于 Oracle 环境 检查的脚本，原理很简单，通过echo cat 把需要注意的，在OS参数设置的信息输出到打印台，可以根据自己需求，增加需要检查的项目
