一 环境准备
1.1安装环境：
本机32位VMware Workstation
操作系统OracleLinux-R6-U3-Server-x86_64-dvd 安装介质： p10404530_112030_Linux-x86-64_3of7.zip p10404530_112030_Linux-x86-64_1of7.zip p10404530_112030_Linux-x86-64_2of7.zip IP分配： 主机名 node1 node2 sacnIP 安装目录： Oracle软件 grid 软件 /s01/oracle/app/oracle/product/11.2.0/dbhome_1 /g01/11ggrid/app/11.2.0/grid 主机IP 172.24.240.72 172.24.240.73 172.24.240.87 PRIV 10.0.0.4 10.0.0.5 VIP 172.24.240.82 172.24.240.83 集群基础包 数据库基础包 数据库基础包 1.2 禁用防火墙和SELNUX（所有节点）
关闭防火墙：
Service iptables status Service iptables stop chkconfig iptables off chkconfig iptables –list
[root@oracle1 ~]# cat /etc/selinux/config
# This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. SELINUX=disabled
# SELINUXTYPE= can take one of these two values: # targeted - Targeted processes are protected, # mls - Multi Level Security protection. SELINUXTYPE=targeted
1.3 修改/etc/hosts 文件（所有节点）

1.4 添加组和用户（所有节点）
node1添加用户和组
groupadd -g 5000 asmadmin groupadd -g 5001 asmdba groupadd -g 5002 asmoper
4
groupadd -g 6000 oinstall groupadd -g 6001 dba groupadd -g 6002 oper
useradd -g oinstall -G asmadmin,asmdba,asmoper grid useradd -g oinstall -G dba,asmdba oracle
node2添加用户和组
groupadd -g 5000 asmadmin groupadd -g 5001 asmdba groupadd -g 5002 asmoper groupadd -g 6000 oinstall groupadd -g 6001 dba groupadd -g 6002 oper
useradd -g oinstall -G asmadmin,asmdba,asmoper grid useradd -g oinstall -G dba,asmdba oracle
设置oracle和grid用户密码（所有节点）
passwd oracle passwd grid
1.5建目录（所有节点）
node1建立目录 mkdir /s01 mkdir /g01
chown oracle:oinstall /s01 chown grid:oinstall /g01 mkdir /g01/orabase mkdir /s01/orabase
chown oracle:oinstall /s01/orabase chown grid:oinstall /g01/orabase
node2建立目录 mkdir /s01 mkdir /g01
chown oracle:oinstall /s01
