软硬件环境：与上一篇文章一致；
集群中增加节点大致分为 4 个步骤：
1. 前期准备阶段；
2. 新节点加入集群（安装 GI 软件）；
3. 新节点安装 DB 软件；
4. 给新节点分配实例；
1.前期准备阶段
IP 配置、系统内核配置、安装 RPM 包、 SHELL 限制、分配用户和组、配置用户环境变量、目录创建及授权、配置互信等等一些前期环境准。
[root@vastdata2 ~]# mkdir -p /u01/app/grid mkdir -p /u01/app/11.2.0/grid mkdir -p /u01/app/oracle chown -R oracle:oinstall /u01 chown -R grid:oinstall /u01/app/grid chown -R grid:oinstall /u01/app/11.2.0 chmod -R 775 /u01
2.新节点加入集群（安装 GI 软件）
2.1对新节点做安装前的检查
