一、RedHat5.5安装【略过不表】
二、配置linux网络环境【/etc/sysconfig/network】【/etc/sysconfig/network-script/ifcfg-eth?】【/etc/hosts】
分别在2个节点编辑/etc/sysconfig/network文件
[root@NEWORACLE1 ~]# cat /etc/sysconfig/network

分别在2个节点编辑/etc/sysconfig/network-scripts/ifcfg-eth[?]文件
[root@NEWORACLE1 ~]# more /etc/sysconfig/network-scripts/ifcfg-eth?

分别在2个节点编辑/etc/hosts文件【两节点内容一致】
[root@NEWORACLE1&2 ~]# vi /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 NEWORACLE2 localhost.localdomain localhost

130.0.100.126 NEWORACLE2-vip
10.0.0.1 NEWORACLE1-priv
10.0.0.2 NEWORACLE2-priv
三、配置操作系统参数
分别在2个节点安装数据库依赖软件包
[root@NEWORACLE1&2 ~]# rpm -q binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel elfutils-libelf-devel-static gcc gcc-c++ glibc glibc-common glibc-devel glibc-headers kernel-headers ksh libaio libaio-devel libgcc libgomp libstdc++ libstdc++-devel make sysstat unixODBC unixODBC-devel libXp

unixODBC-2.2.11-7.1

分别在2个节点修改参数&变量
修改内核参数
[root@NEWORACLE1&2 ~]# vi /etc/sysctl.conf
添加
kernel.shmall = 17179869184
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 = 1048576
net.core.rmem_max = 1048576
net.core.wmem_default = 262144
net.core.wmem_max = 262144
使更改立即生效
[root@NEWORACLE1&2 ~]# sysctl -p
net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
kernel.sysrq = 0
kernel.core_uses_pid = 1
net.ipv4.tcp_syncookies = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.shmmax = 68719476736
kernel.shmall = 17179869184
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 = 1048576
net.core.rmem_max = 1048576
net.core.wmem_default = 262144
net.core.wmem_max = 262144
设置oracle用户的shell limit
[root@NEWORACLE1&2 ~]# vi /etc/security/limits.conf
添加
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
接下来更改/etc/pam.d/login文件，添加下面的内容，使shell limit生效：
==32位环境==
[root@NEWORACLE1&2 ~]# vi /etc/pam.d/login
添加
session required /lib/security/pam_limits.so
session required pam_limits.so
==64位环境==
[root@NEWORACLE1&2 ~]# vi /etc/pam.d/login
添加
session required pam_limits.so
配置Hangcheck计时器
[root@NEWORACLE1&2 ~]# vi /etc/rc.local
增加：
modprobe hangcheck-timer hangcheck-tick=30 hangcheck_margin=180
四、配置用户、组、权限【oracle】【dba】【oinstall】
分别在2个节点创建用户与组
[root@NEWORACLE1&2 ~]# groupadd -g 1000 oinstall
[root@NEWORACLE1&2 ~]# groupadd -g 1001 dba
[root@NEWORACLE1&2 ~]# useradd -u 500 -g oinstall -G dba oracle
[root@NEWORACLE1&2 ~]# 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@NEWORACLE1&2 ~]# id nobody
uid=99(nobody) gid=99(nobody) groups=99(nobody)
分别在2个节点配置环境变量
[root@NEWORACLE1&2 ~]# vi /etc/profile
添加
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
PS1='[`date +%H:%M:%S `\u@\h \W]>'
[root@NEWORACLE1&2 ~]# vi /etc/csh.login
添加
if ( $USER == "oracle" ) then
limit maxproc 16384
limit descriptors 65536
endif
[oracle@NEWORACLE1&2 oracle]$ vi ~/.bash_profile
export ORACLE_BASE=/home/oracle
export ORA_CRS_HOME=$ORACLE_BASE/product/10.2.0/crs
export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1
export ORACLE_SID=orcl
export PATH=$PATH:$ORA_CRS_HOME/bin:$ORACLE_HOME/bin:.
umask 022
分别在2个节点配置Oracle用户等价性
[oracle@NEWORACLE1 oracle]$ >ssh-keygen -t dsa
Generating public/private dsa key pair.
Enter file in which to save the key (/home/oracle/.ssh/id_dsa):
Created directory '/home/oracle/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/oracle/.ssh/id_dsa.
Your public key has been saved in /home/oracle/.ssh/id_dsa.pub.
The key fingerprint is:
f3:c8:dd:14:99:0d:46:da:08:2b:a6:85:dc:8c:15:a4 oracle@node1.wanglei.com
[oracle@NEWORACLE1 oracle~]>cd .ssh
[oracle@NEWORACLE1 oracle .ssh]>cp id_dsa.pub authorized_keys
[oracle@NEWORACLE2 oracle ~]>ssh-keygen -t dsa
Generating public/private dsa key pair.
Enter file in which to save the key (/home/oracle/.ssh/id_dsa):
Created directory '/home/oracle/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/oracle/.ssh/id_dsa.
Your public key has been saved in /home/oracle/.ssh/id_dsa.pub.
The key fingerprint is:
f3:c8:dd:14:99:0d:46:da:08:2b:a6:85:dc:8c:15:a4 oracle@node1.wanglei.com
[oracle@NEWORACLE2 oracle~]>cd .ssh
[oracle@NEWORACLE2 oracle .ssh]>cp id_dsa.pub authorized_keys
然后分别在2个节点viauthorized_keys文件，将对方节点的id_dsa.pub信息添加进去，然后分别在两节点做如下测试：
[oracle@NEWORACLE1 oracle~]>ssh NEWORACLE1
[oracle@NEWORACLE1 oracle~]>ssh NEWORACLE2
[oracle@NEWORACLE1 oracle~]>ssh NEWORACLE1-priv
[oracle@NEWORACLE1 oracle~]>ssh NEWORACLE2-priv
[oracle@NEWORACLE2 oracle~]>ssh NEWORACLE1
[oracle@NEWORACLE2 oracle~]>ssh NEWORACLE2
[oracle@NEWORACLE2 oracle~]>ssh NEWORACLE1-priv
[oracle@NEWORACLE2 oracle~]>ssh NEWORACLE2-priv
五、配置共享磁盘(root权限执行）
