安装软件包
rpm -ivh libaio-devel*.rpm sysstat-7.0.2-3*.rpm unixODBC-2.2.11-7.1.i386.rpm unixODBC-devel-2.2.11-7.1.i386.rpm
2> 检查内存与虚拟内存
[root@node1 opt]# free
total used free shared buffers cached
Mem: 681540 415396 266144 0 4612 310660
-/+ buffers/cache: 100124 581416
Swap: 2048276 84 2048192
3> 检查磁盘空间
[root@node1 opt]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 18G 5.3G 12G 33% /
/dev/sda1 190M 12M 169M 7% /boot
tmpfs 333M 0 333M 0% /dev/shm
4> 查看系统版本
[root@node1 opt]# uname -a
Linux node1.cn1 2.6.18-194.el5 #1 SMP Tue Mar 16 21:52:43 EDT 2010 i686 i686 i386 GNU/Linux
5> 配置主机名
[root@node1 /]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
192.168.1.201 node1.cn node1
[root@node1 /]# cat /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=node1.cn
GATEWAY=192.168.1.254
6> 创建安装用户与组 安装目录
[root@node1 /]# groupadd -g 1001 oinstall
[root@node1 /]# groupadd -g 1002 dba
[root@node1 /]# useradd -u 1001 -g oinstall -G dba oracle
[root@node1 /]# 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@node1 /]# mkdir -p /u01/app/oracle //软件安装目录
[root@node1 /]# chown -R oracle:oinstall /u01
# mkdir -p /opt/oradata //oracel 数据存放目录
# chown -R oracle:oinstall /opt
# chmod -R 775 /opt/
7> 修改系统内核参数:
[root@node1 opt]# vi /etc/sysctl.conf
===========================================
kernel.shmall = 2097152
kernel.shmmax = 536870912 //物理内存1半
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.aio-max-nr = 1048576
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 1048576 //1M
net.core.rmem_max = 1048576
net.core.wmem_default = 262144 //256K
net.core.wmem_max = 262144
[root@node1 opt]# /sbin/sysctl -p //使内核参数即使生效
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.shmall = 2097152 //可用共享内存的总量，单位是页，在32位系统上一页等于4kB，也就是4096字节
kernel.shmmax = 536870912 //单个共享内存段的最大值,此值一般为物理内存的一半，不过大一点也没关系
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128 //设置的信号量，这4个参数内容大小固定
fs.file-max = 65536 //文件句柄的最大数量。文件句柄表示在Linux系统中可以打开的文件数量
fs.aio-max-nr = 1048576 //文件系统最大异步io
net.ipv4.ip_local_port_range = 9000 65500 //应用程序可使用的IPv4端口范围
net.core.rmem_default = 1048576
net.core.rmem_max = 1048576 //接收套接字缓冲区大小的最大值
net.core.wmem_default = 262144
net.core.wmem_max = 262144 //发送套接字缓冲区大小的最大值
8> 设置oracle使用的文件数权限
[root@node1 opt]# vi /etc/security/limits.conf
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
9> 用户界面安全设置
[root@node1 opt]# vi /etc/pam.d/login
session required /lib/security/pam_limits.so
session required pam_limits.so
10> 用户访问端口范围设置
[root@node1 opt]# vi /etc/profile
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
11> 设置用户环境变量
[root@node1 opt]# su - oracle
[oracle@node1 ~]$ vi .bash_profile
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11g
export ORACLE_SID=orcl

CLASSPATH=$CLASSPATH:$ORACLE_HOME/network/jlib
export CLASSPATH
[oracle@node1 ~]$ source .bash_profile //使环境变量即使生效
12> 准备进入界面安装程序
[root@node1 /]# xhost +

[root@node1 /]# su - oracle
[oracle@node1 database]$ cd /opt/database/ //进入安装文件存储目录
