![二.向 Rac Cluster 中加入新的节点
1.在原有 RAC 节点上(vrh1)以 oracle 用户身份登录，设置合理的 DISPLAY 显示环境变量，并
运行$ORA_CRS_HOME/oui/bin 目录下的 addNode.sh 脚本
[oracle@vrh1 ~]$ export DISPLAY=IP:0.0
[oracle@vrh1 ~]$ cd $ORA_CRS_HOME/oui/bin
[oracle@vrh1 bin]$ ./addNode.sh
2.若 OUI 被正常调用则会出现欢迎界面，并点击 NEXT:](https://image.slidesharecdn.com/10graccluster-110912081840-phpapp02/85/10g-rac-cluster-4-320.jpg)
![5.出现”Cluster Node Addition Progress”界面，OUI 成功将安装好的 clusterware 软件传输到新
的节点后，会提示用户运行多个脚本包 括:orainstRoot.sh(新节点)、rootaddnode.sh(运行 OUI
的原有节点)、root.sh(新节点)：
6.运行之前提示的三个脚本:

为10g rac cluster添加节点
本文介绍了如何为 Oracle 10g RAC 集群添加新节点的步骤，过程中包括配置新服务器的硬件和操作系统环境、添加节点和安装 Oracle 数据库软件等几个关键步骤。作者详细列出了每个步骤所需要的命令和注意事项，确保新节点能够成功加入集群并正常运行。此文档对系统管理员和数据库管理员在扩展 RAC 集群时具有重要参考价值。

- 3. RAC 体系为系统扩容开创了一条新的道路：只需要不断向集群 Cluster中加入新的服务器就 可以了。这里我们就来介绍一下如何为 10g RAC Cluster 增加节点；实际上这并不复杂，甚 至可以说是很简单的。为现有的 Oracle 10g RAC 添加节点大致包括以下步骤: 1. 配置新的服务器节点上的硬件及操作系统环境 2. 向 Cluster 集群中加入该节点 3. 在新节点上安装 Oracle Database software 4. 为新的节点配置监听器 LISTENER 5. 通过 DBCA 为新的节点添加实例 我们假设当前 RAC 环境中存在 2 个节点，分别为 vrh1 和 vrh2；该 RAC 环境中 clusterware 和 database 的版本均为 10.2.0.4,需要加入该 Cluster 的新节点为 vrh3。 一、在新的服务器节点上配置操作系统环境 1. 这包括配置该节点今后使用的 public network 公用网络和 private network 接口，不要忘 记在 hosts 文件中加入之前节点的网络信息，并将该份完整的 hosts 文件传到集群 Cluster 中已有的节点上，保证处处可以访问 2. 同时需要在原有的基础上配置 oracle(或其他 DBA)用户的身份等价性，这需要将新节 点上生成的 id_rsa.pub 和 id_dsa.pub 文件中的信息追加到 authorized_keys 文件中，并 保证在所有节点上均有这样一份相同的 authorized_keys 文件 3. 调整新节点上的操作系统内核参数，保证其满足今后在该节点上运行实例的内存要求 以及 10g RAC Cluster 的推荐的 udp 网络参数 4. 调整新节点上的系统时间以保持同其他节点一致，或者配置 NTP 服务 5. 保证原有 Cluster 中所有节点上的 CRS 都正常运行，否则 addNode 时会报错 6. 配置 clusterware 和 database 软件的安装目录，要求路径和原有节点上的一致
- 4. 二.向 Rac Cluster中加入新的节点 1.在原有 RAC 节点上(vrh1)以 oracle 用户身份登录，设置合理的 DISPLAY 显示环境变量，并 运行$ORA_CRS_HOME/oui/bin 目录下的 addNode.sh 脚本 [oracle@vrh1 ~]$ export DISPLAY=IP:0.0 [oracle@vrh1 ~]$ cd $ORA_CRS_HOME/oui/bin [oracle@vrh1 bin]$ ./addNode.sh 2.若 OUI 被正常调用则会出现欢迎界面，并点击 NEXT:
- 5. 3.在”Specify Cluster Nodesto Add to Installation”界面下输入公共节点名、私有节点名和 VIP 节点名(之前应当在所有节点的/etc/hosts 文件中都配置了):
- 6. 4.出现”Cluster Node AdditionSummary”界面 Review 一遍 Summary 信息，并点击 NEXT:
- 7. 5.出现”Cluster Node AdditionProgress”界面，OUI 成功将安装好的 clusterware 软件传输到新 的节点后，会提示用户运行多个脚本包 括:orainstRoot.sh(新节点)、rootaddnode.sh(运行 OUI 的原有节点)、root.sh(新节点)： 6.运行之前提示的三个脚本: /* 在新节点上运行 orainstRoot.sh 脚本 */ [root@vrh3 ~]# /s01/oraInventory/orainstRoot.sh Changing permissions of /s01/oraInventory to 770.
