IP地址划分:
192.168.3.30 rac10g01 eth0
192.168.3.40 rac10g01 eth0
192.168.3.50 rac10g01-vip eth0:1
192.168.3.60 rac10g02-vip eth0:1
10.0.0.1 rac10g01-priv eth1
10.0.0.2 rac10g02-priv eth1
IP说明:
每台服务器必须两块网卡, public ip和priv ip不能在同一网段.public和priv必须在网卡中写明地址,vip在地址是数据库自己添加的.
1.安装操作系统,图形化安装
安装系统时将iptable和selinux全部禁用
2.配置虚拟机的网卡

3.配置hosts文件,主机名与IP地址解析(两个节点都是一样的)
[root@rac10g01 ~]# vim /etc/hosts
192.168.3.30 localhost.localdomain localhost --在两个节点分别写入这行,IP地址是本机的
192.168.3.30 rac10g01
192.168.3.40 rac10g02
192.168.3.50 rac10g01-vip
192.168.3.60 rac10g02-vip
10.0.0.1 rac10g01-priv
10.0.0.2 rac10g02-priv
[root@rac10g01 ~]# ping rac10g01 --所有的地址都ping一下,检查是否有问题
4.光盘镜像挂载,安装软件依赖包(两个节点是一样的)
[root@rac10g01 ~]# mount /dev/hdc /mnt/cdrom/
mount: block device /dev/hdc is write-protected, mounting read-only
[root@rac10g01 ~]# vim /etc/yum.repos.d/tong.repo
[tong]
name=tong
baseurl=file:///mnt
gpgkey=file:///mnt/cdrom/RPM-GPG-KEY-oracle
gpgcheck=1
enabled=1
[root@rac10g01 ~]# yum list
[root@rac10g01 ~]# yum install binutils compat-db compat-libstdc++-296 control-center gcc gcc-c++ glibc glibc-common libstdc++ libstdc++-devel make sysstat setarch glibc-devel libaio ksh glibc-headers libgnome libgcc libgnomeui libgomp openmotif libXp -y
[root@rac10g01 ~]#

kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 262144
net.core.rmem_max = 262144
net.core.wmem_default = 262144
net.core.wmem_max = 262144
[root@rac10g01 ~]# sysctl -p
6.创建用户，用户组,用户设置密码(两个节点必须一至)

[root@rac10g01 ~]# groupadd -g 501 dba
[root@rac10g01 ~]# groupadd -g 502 oper
[root@rac10g01 ~]# groupadd -g 503 asmadmin
[root@rac10g01 ~]# groupadd -g 504 asmdba
[root@rac10g01 ~]# groupadd -g 505 asmoper
[root@rac10g01 ~]# useradd -u 1000 -g oinstall -G dba,oper,asmdba -d /home/oracle oracle
[root@rac10g01 ~]# passwd oracle
Changing password for user oracle.
New UNIX password:
BAD PASSWORD: it is based on a dictionary word
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
[root@rac10g01 ~]#
7.创建oracle与grid存放的目录(两个节点必须一至)
[root@rac10g01 ~]# mkdir -p /u01/oracle/product/10.2.0.1/db_1
[root@rac10g01 ~]# mkdir -p /u01/oracle/product/10.2.0.1/crs_1

oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft memlock 5242880
oracle hard memlock 524280
[root@rac10g01 ~]#
9.添加oracle用户的环境变量(两个节点一至)

export ORACLE_BASE=/u01/oracle
export ORACLE_HOME=$ORACLE_BASE/product/10.2.0.1/db_1
export CRS_HOME=$ORACLE_BASE/product/10.2.0.1/crs_1

export ORACLE_SID=rac10g1
export PATH=$PATH:$ORA_CRS_HOME/bin:$ORACLE_HOME/bin
[root@rac10g01 ~]# . /home/oracle/.bash_profile
10.oracle用户的ssh互相信任(两个节点一至)
