添加新节点oracle10g rac(rhel4)_clusterware(一)

1,根据配置好的rac节点，搭建相关环境
   a,os rpm包（参考oracle document)
   b,os 配置文件(limits.conf)
   c,/etc/hosts文件
   d,连通新节点与存储
   e,编辑修改/boot/grub/grub及modprobe.conf文件（可参对我以前的rac文档）
   f,配置raw，asm根据已有rac节点,当然若启用了ocfs，请查阅相关文档
   g,把相关的权限及授权动作写入/etc/rc.d/rc.local（可查阅已存rac节点）
2,在已有rac节点以oracle用户运行addnodes.sh脚本
3,以上脚本运行，可能会提示所选节点capitek3不可访问（这是三节点的ssh通讯配置有问题，重配就可）；若cluster未启动，报错如下：
  rac 启动与addnodes.sh错误日志关系

[root@capitek1 logs]#
 以上不言自喻，启动cluster就行（表现症状：在选择新增节点的对话框中：vip and private ip名字是空的）



4,继续运行会提示要运行一个runinstaller脚本，先在新增节点运行它,然后继续运行cluster软件安装对话框

5,最后在新增节点运行root.sh提示如下：
[root@capitek3 /]# /u01/app/oracle/oraInventory/orainstRoot.sh

可先用crs_stat -t与ifconfig相关clusterware服务是否正常（ps -ef)，若正常，可不用运行vipca


6,在已有节点以oracle用户运行/u01/app/oracle/product/10.2.0/crs_1/bin/racgons add_config capitek3:6200
   (新增节点端口号信息可取自于：more product/10.2.0/crs_1/opmn/conf/ons.config )

这就完成了新增节点rac cluster软件的配置
