添加节点场景
1、集群扩容
2、节点损坏后进行了删除操作，之后又要求恢复删除节点
环境和需求说明
由于3节点RAC，其中节点3因为本地盘损坏，导致系统完全损坏，系统需要重新安装。将损坏的3节点删除后再进行添加。
数据库版本： 11.2.0.4 RAC 3节点
虚拟环境系统： Centos 7.9
需求：将已删除的损坏的第3个节点racdb03重新加入集群中

添加前准备
节点3的Linux服务器配置
添加节点前需对节点3的服务器参数进行配置，仅在节点3上操作。
重新安装操作系统
操作系统版本，内存、CPU、硬盘等配置和其他2个保留节点保持一致或更高。
重新配置服务器环境
时区设置
根据客户标准设置 OS 时区，国内通常为东八区"Asia/Shanghai".
在安装 GRID 之前，一定要先修改好 OS 时区，否则 GRID 将引用一个错误的 OS 时区，导致 DB 的时区，监听的时区等不正确。
--新增加节点要和原有2个节点保持一致

配置SSH信任关系
在新增节点上做如下操作，racdb01和racdb02由于已经有ssh的等效性，所以需要把authorized_keys文件分别拷贝到racdb01和racdb02，包含grid用户和oracle用户。
如果未进行配置，后面在任一保留节点执行并生成校验准备命令时会有PRVF-4007的错误发生。

Pre-check for node addition was unsuccessful on all the nodes.补充说明：
1、以上检查部分报错可以忽略，如/etc/resolv.conf报错，若没有用DNS所以忽略，DNS服务器超时也可以忽略。
2、如果内核参数校验失败会输出让在racdb03上用root身份运行/tmp/CVU_11.2.0.4.0_grid/runfixup.sh自动修复一些内核参数的失败项的内容。如下所示：
Fixup information has been generated for following node(s):
host03
Please run the following script on each node as "root" user to execute the fixups:
'/tmp/CVU_11.2.0.4.0_grid/runfixup.sh'3、如果SSH等效性配置有问题会输出如下报错：
PRVF-4007的错误发生，此时应该进行SSH等效性配置。在racdb03 作如下操作，racdb01和racdb02由于已经有ssh的等效性，所以需要最后把authorized_keys文件拷贝到racdb01和racdb02，grid用户和oracle用户分别都操作。

Grid Infrastructure层面添加新节点
导入ignore_preaddnode_checks环境变量(在任一保留节点)
保留节点上执行添加节点，拷贝软件信息
本文档在节点1上即racdb01节点导入ignore_preaddnode_checks环境变量
grid用户下操作，前提所有节点间已做好grid用户的ssh互信配置，不然添加过程中报错。
导入ignore_preaddnode_checks环境变量，否则后面的命令无法安装

因为centos7 使用的sysemd而不时initd运行继承和重启进程，而root.sh通过传统的initd运行ohasd进程
