一、修改操作系统文件

1、配置主机名：

[root@x3a-test ~]# hostname x3a-test

[root@x3a-test ~]# hostname

x3a-test

[root@x3a-test ~]# vi /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=x3a-test

2、修改 /etc/hosts文件

[root@x3a-test cdrom]# vi /etc/hosts

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1 localhost.localdomain localhost

192.168.2.6 x3a-test

[@more@]

3、修改/etc/sysctl.conf文件:

文件最后追加如下内容

[root@x3a-test ~]# vi /etc/sysctl.conf

#Oracle Install Paramaters

kernel.shmall = 2097152

kernel.shmmax = 2147483648

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

然后执行如下命令，让修改的参数生效

[root@x3a-test ~]# 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

kernel.shmall = 2097152

kernel.shmmax = 2147483648

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

4、修改/etc/security/limits.conf 文件

文件最后增加如下内容：

* soft nproc 2047

* hard nproc 16384

* soft nofile 1024

* hard nofile 65536

5、修改/etc/pam.d/login文件

文件最后增加如下内容：

[root@x3a-test ~]# vi /etc/pam.d/login

session required /lib/security/pam_limits.so

5、查看或配置网络

[root@x3a-test cdrom]# vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

BOOTPROTO=none

BROADCAST=192.168.2.255

HWADDR=84:8F:69:DB:5A:89

IPADDR=192.168.2.6

NETMASK=255.255.255.0

NETWORK=192.168.2.1

ONBOOT=yes

TYPE=Ethernet

USERCTL=no

IPV6INIT=no

PEERDNS=yes

GATEWAY=192.168.2.1

二、创建Orcale组及用户：

[root@localhost ~]# groupadd oinstall

[root@localhost ~]# groupadd dba

[root@localhost ~]# useradd -g oinstall -G dba oracle

[root@localhost ~]# 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.

三、创建Orcale相关目录：

[root@localhost ~]# mkdir -p /opt/oracle/product/10.2.0/database

[root@localhost ~]# chown -R oracle.oinstall /opt/oracle

[root@localhost ~]# chown -R /opt/oracle

[root@localhost ~]# chmod -R 775 /opt/oracle

四、为Oracle用户配置环境变量：

[root@x3a-test ~]# su - oracle

[oracle@x3a-test ~]$ vi .bash_profile

# Oracle Settings

TMP=/tmp; export TMP

TMPDIR=$TMP; export TMPDIR

ORACLE_BASE=/opt/oracle; export ORACLE_BASE

ORACLE_HOME=$ORACLE_BASE/product/10.2.0/database; export ORACLE_HOME

ORACLE_SID=test; export ORACLE_SID

ORACLE_TERM=xterm; export ORACLE_TERM

PATH=/usr/sbin:$PATH; export PATH

PATH=$ORACLE_HOME/bin:$PATH; export PATH

LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH

CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib;

export CLASSPATH

五、解压Oracle安装程序软件

[root@x3a-test opt]# su - oracle

[oracle@x3a-test ~]$ cd /opt/

[oracle@x3a-test opt]$ ls

10201_database_linux32.zip lost+found oracle

[oracle@x3a-test opt]$ unzip 10201_database_linux32.zip

...

[oracle@x3a-test opt]$ ls

10201_database_linux32.zip database lost+found oracle

六、配置图形显示环境并执行runInstaller脚本开始安装数据库软件：

Oracle的安装环境需要配置图形界面功能，具体有如下三种方式：

1、以Oracle用户直接登录服务器图像界面执行runInstaller

2、通过Xmanager的客户端工具，在客户端现实图形界面的方式安装

3、通过Linux自带的vncserver配置和启动来客户端现实图形界面，然后执行runInstaller脚本，例如：

[root@x3a-test ~]# xhost +

access control disabled, clients can connect from any host

[root@x3a-test ~]# su - oracle

[oracle@x3a-test ~]$ export LANG=en

[oracle@x3a-test ~]$ cd /opt/

[oracle@x3a-test opt]$ ls

10201_database_linux32.zip database lost+found oracle

[oracle@x3a-test opt]$ cd database/

[oracle@x3a-test database]$ ls

doc install response runInstaller stage welcome.html

[oracle@x3a-test database]$ ./runInstaller

Starting Oracle Universal Installer...
