一，基本配置：

1.以root登录，挂载linux iso文件

[root@oracle ~]# hostname

oracle.junjie.com

[root@oracle ~]# cat /etc/sysconfig/network

NETWORKING=yes

NETWORKING_IPV6=no

HOSTNAME=oracle.junjie.com

[root@oracle ~]# ifconfig eth0

eth0 Link encap:Ethernet HWaddr 00:0C:29:65:FC:1D

inet addr:192.168.101.88 Bcast:192.168.101.255 Mask:255.255.255.0

[root@oracle ~]# mkdir /mnt/cdrom/

[root@oracle ~]# mount /dev/cdrom /mnt/cdrom/

mount: block device /dev/cdrom is write-protected, mounting read-only

2. 检查包是否安装

[root@oracle ~]# cd /mnt/cdrom/Server/

libXp-1.0.0-8.1.el5.i386.rpm

binutils-2.17.50.0.6-12.el5.i386.rpm

compat-db-4.2.52-5.1.i386.rpm

compat-libstdc++-296-2.96-138.i386.rpm

control-center-2.16.0-16.el5.i386.rpm

gcc-4.1.2-46.el5.i386.rpm

gcc-c++-4.1.2-46.el5.i386.rpm

glibc-2.5-42.i386.rpm

glibc-common-2.5-42.i386.rpm

libstdc++-4.1.2-46.el5.i386.rpm

libstdc++-devel-4.1.2-46.el5.i386.rpm

make-3.81-3.el5.i386.rpm

pdksh-5.2.14-36.el5.i386.rpm

sysstat-7.0.2-3.el5.i386.rpm

setarch-2.0-1.1.i386.rpm

[root@oracle Server]# rpm -ivh libXp-1.0.0-8.1.el5.i386.rpm

[root@oracle Server]# rpm -ivh binutils-2.17.50.0.6-12.el5.i386.rpm

[root@oracle Server]# rpm -ivh compat-db-4.2.52-5.1.i386.rpm

[root@oracle Server]# rpm -ivh compat-libstdc++-296-2.96-138.i386.rpm

[root@oracle Server]# rpm -ivh control-center-2.16.0-16.el5.i386.rpm

[root@oracle Server]# rpm -ivh gcc-4.1.2-46.el5.i386.rpm

[root@oracle Server]# rpm -ivh gcc-c++-4.1.2-46.el5.i386.rpm

[root@oracle Server]# rpm -ivh glibc-2.5-42.i386.rpm

[root@oracle Server]# rpm -ivh glibc-common-2.5-42.i386.rpm

[root@oracle Server]# rpm -ivh libstdc++-4.1.2-46.el5.i386.rpm

[root@oracle Server]# rpm -ivh libstdc++-devel-4.1.2-46.el5.i386.rpm

[root@oracle Server]# rpm -ivh make-3.81-3.el5.i386.rpm

[root@oracle Server]# rpm -ivh pdksh-5.2.14-36.el5.i386.rpm

[root@oracle Server]# rpm -ivh sysstat-7.0.2-3.el5.i386.rpm

[root@oracle Server]# rpm -ivh setarch-2.0-1.1.i386.rpm

3.修改/etc/hosts文件

[root@oracle ~]# echo "192.168.101.88 oracle.junjie.com" 》/etc/hosts

4.新建用户和组

[root@oracle ~]# groupadd dba

[root@oracle ~]# groupadd oinstall

[root@oracle ~]# groupadd oper

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

[root@oracle ~]# echo 'zhu.110' |passwd --stdin oracle

Changing password for user oracle.

passwd: all authentication tokens updated successfully.

5.添加文件

[root@oracle ~]# vim /etc/sysctl.conf

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 = 1048576

net.core.rmem_max = 1048576

net.core.wmem_default = 262144

net.core.wmem_max = 262144

[root@oracle ~]# vim /etc/security/limits.conf

oracle soft nproc 2047

oracle hard nproc 16384

oracle soft nofile 1024

oracle hard nofile 65536

[root@oracle ~]# vim /etc/pam.d/login

session required /lib/security/pam_limits.so

session required pam_limits.so

[root@oracle ~]# vim /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

6. 新建文件，修改权限

[root@oracle ~]# mkdir /u01

[root@oracle ~]# mkdir -pv /u01/app/oracle

mkdir: created directory `/u01/app'

mkdir: created directory `/u01/app/oracle'

[root@oracle ~]# chown -R oracle:oinstall /u01/app/oracle/

[root@oracle ~]# chmod -R 775 /u01/app/oracle/

[root@oracle ~]# mkdir /u01/flash_recovery_area

[root@oracle ~]# chown oracle:oinstall /u01/flash_recovery_area/

[root@oracle ~]# chmod 755 /u01/flash_recovery_area/

二。安装oracle

2.1.添加以下几行

[root@oracle ~]# su - oracle

[oracle@oracle ~]$ vim .bash_profile

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=/u01/app/oracle/product/10.2.0

export ORACLE_SID=xjzhujunjie

[oracle@oracle ~]$ . .bash_profile

[oracle@oracle ~]$ env | grep ORA

ORACLE_SID=xjzhujunjie

ORACLE_BASE=/u01/app/oracle

ORACLE_HOME=/u01/app/oracle/product/10.2.0

2.2更换光盘

[root@oracle ~]# umount /mnt/cdrom/

我使用的光盘是：（ora102forlinux.iso）

[root@oracle ~]# mount /dev/cdrom /mnt/cdrom/

mount: block device /dev/cdrom is write-protected, mounting read-only

[root@oracle ~]# ll /mnt/cdrom/

total 2

dr-xr-xr-x 1 root root 2048 Jul 2 2005 database

[root@oracle ~]#

2.3 测试图形界面（$）

测试图形界面（$）出现以下为正常，

若不成功则：#xhost local:oracle（后到VM中测试）
