redhat5上 安装oracle10g 步骤

挂在光驱：mount /dev/cdrom /media/

1. 确保selinux中的值如下
SELINUX=disabled
SELINUXTYPE=disabled

2. 添加oracle用户和组
groupadd oinstall
groupadd dba
useradd -m -g oinstall -G dba oracle

passwd oracle

3. 创建安装目录并赋予oracle相应权限
mkdir -p /u01/app/oracle/product/10.2.0/db_1
chown -R oracle:oinstall /u01
chmod -R 775 /u01

4. 安装系统缺失的包
确保如下包都有安装
gcc-4.1.1-52.el5
make-3.81-1.1
binutils-2.17.50.0.6-2.el5
openmotif
setarch-2.0-1.1
compat-db
compat-gcc
compat-gcc-c++
compat-libstdc++
compat-libstdc++-devel

如果没有安装请从光盘安装，由于缺失的包之间有严格的依赖关系，所以必须按照如下顺序安装缺失的包
rpm -Uvh compat-db-4*
rpm -Uvh libaio-0*
rpm -Uvh compat-libstdc++-33-3*
rpm -Uvh glibc-headers-2.5-12.i386.rpm
rpm -Uvh glibc-devel-2.5-12.i386.rpm
rpm -Uvh compat-gcc-34-3*
rpm -Uvh compat-gcc-34-c++-3*
rpm -Uvh libXp-1*
rpm -Uvh openmotif-2*
rpm -Uvh gcc-4*
rpm -Uvh glibc-2.5-12.i686.rpm
rpm -Uvh libgomp-4.1.1-52.el5.i386.rpm
rpm -Uvh gcc-4.1.1-52.el5.i386.rpm
rpm -Uvh compat-readline43-4.3-3.x86_64.rpm

如果安装完成后仍然提示部分包没有安装，不过不影响使用
package compat-gcc is not installed
package compat-gcc-c++ is not installed
package compat-libstdc++ is not installed
package compat-libstdc++-devel is not installed

5.修改系统参数
vi /etc/sysctl.conf 增加如下参数
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
运行下面命令使设置生效/sbin/sysctl -p

vi /etc/security/limits.conf 增加如下参数
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536

6、修改操作系统的版本
vi /etc/redhat-release
Red Hat Enterprise Linux Server release 5 (Tikanga) 替换成 redhat-4

7.设置主机名和IP
vi /etc/hosts
删除文件内容，添加如下两行
127.0.0.1 localhost
IP地址 主机名称
如果不添加第一行，安装以后数据库可以打开，通过http://ip:1158/em访问 控制台发现数据库和监听器均无法启动（箭头指向下）以管理员帐号进入em

8. 修改oracle的环境变量
su - oracle
vi ~/.bash_profile
export DISPLAY="192.168.2.81:0.0"
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1
export ORACLE_SID=wlvm
export ORACLE_TERM=xterm
export PATH=$ORACLE_HOME/bin:/usr/sbin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
#export LD_ASSUME_KERNEL=2.6.9
export LANG=en_US.utf8
export LANGUAGE=en_US.utf8
export NLS_LANG="Simplified Chinese_China.UTF8"
export LC_ALL=en_US.utf8

if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
umask 022

9. 安装oracle
以oracle用户登录系统，打开终端将当前位置定位到database中
Unset LANG
./runInstaller.sh
如果之前的包按照要求安装完成，安装过程应该很顺利
sqlplus ‘/as sysdba'
启动数据库
startup
启动控制台
emctl start dbconsole
启动监听器
lsnrctl start
http://ip:1158/em
启停isqlplus应用服务器
isqlplusctl stop
isqlplusctl start

10. 后修改vi /etc/redhat-release 内容为Red Hat Enterprise Linux Server release 5 (Tikanga)

11. 设置开机启动
vi /etc/oratab
wlvm:/u01/app/oracle/product/10.2.0/db_1:Y
