Redhat5.4下安装oracle10g

1 修改Linux参数
（1） 修改/etc/sysctl.conf，核心参数
[root@applecat ~]# gedit /etc/sysctl.conf
在文件尾部添加如下内容：
# For Oracle Install
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
使配置生效：
[root@applecat ~]# /sbin/sysctl -p
（2） 修改/etc/security/limits.conf，可选
[root@applecat ~]# gedit /etc/security/limits.conf
在文件尾部增加：
* soft nproc 2047
* hard nproc 16384
* soft nofile 1024
* hard nofile 65536
(3) 修改/etc/pam.d/login，可选

在尾部添加一行：
session required /lib/security/pam_limits.so
(4) 修改/etc/profile，可选
[root@applecat ~]# gedit /etc/profile
在尾部添加：
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
2 安装Linux软件包

[root@applecat Server]# rpm -ivh libstdc++-devel-4.1.2-46.el5.i386.rpm
[root@applecat Server]# rpm -ivh gcc-4.1.2-46.el5.i386.rpm
[root@applecat Server]# rpm -ivh compat-gcc-34-3.4.6-4.i386.rpm
[root@applecat Server]# rpm -ivh compat-gcc-34-c++-3.4.6-4.i386.rpm
(3) 安装openmotif软件包
[root@applecat Server]# rpm -Uvh libXp-1.0.0-8.1.el5.i386.rpm
[root@applecat Server]# rpm -Uvh openmotif-2.3.1-2.el5.i386.rpm
(4) 再次检查包安装
[root@applecat Server]# rpm -q gcc make binutils openmotif
gcc-4.1.2-46.el5
make-3.81-3.el5
binutils-2.17.50.0.6-12.el5
openmotif-2.3.1-2.el5
(5) 检查其它包安装情况
[root@applecat Server]# rpm -q gcc make binutils openmotif setarch compat-db compat-gcc /
> compat-gcc-c++ compat-libstdc++ compat-libstdc++-devel
gcc-4.1.2-46.el5
make-3.81-3.el5
binutils-2.17.50.0.6-12.el5
openmotif-2.3.1-2.el5
setarch-2.0-1.1
package compat-db is not installed
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
(6) 安装其它包。
[root@applecat Server]# rpm -Uvh compat-db-4*

3 关闭Linux防火墙
[root@applecat ~]# gedit /etc/selinux/config
编辑：
SELINUX=disabled
4 重启Linux。
5 创建oracle用户和组，并修改oracle用户密码。
[root@applecat ~]# groupadd oinstall
[root@applecat ~]# groupadd dba
[root@applecat ~]# useradd -m -g oinstall -G dba oracle
[root@applecat ~]# id oracle
uid=501(oracle) gid=501(oinstall) groups=501(oinstall),502(dba) context=root:system_r:unconfined_t:SystemLow-SystemHigh
[root@applecat ~]# 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.
6 开始安装oracle 10gR2
（1） 修改oracle用户os参数文件：.bash_profile
将如下内容添加到文件尾部：
# Oracle Settings
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR

ORACLE_BASE=/home/oracle/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1; export ORACLE_HOME
ORACLE_SID=orcl; export ORACLE_SID
ORACLE_TERM=xterm; export ORACLE_TERM
PATH=$PATH:$HOME/bin
export PATH=$PATH:/sbin

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

if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1;
export ORACLE_HOME
（2）创建oracle临时安装目录
[root@applecat home]# cd /home
[root@applecat home]# mkdir orainstall
[root@applecat home]# chown oracle:oinstall orainstall
（3）将oracle10g安装文件拷贝至安装目录并解压缩
拷贝下载好的oracle10g文件到/home/orainstall目录下
[root@applecat home]# su – oracle
[oracle@applecat orainstall]$ cd /home/orainstall
[oracle@applecat orainstall]$ pwd
/home/orainstall
[oracle@applecat orainstall]$ ls
10201_database_linux32.zip
[oracle@applecat orainstall]$ unzip 10201_database_linux32.zip
[oracle@applecat orainstall]$ ls
10201_database_linux32.zip database
注意：database为安装目录
（4）开始安装oracle10g
[oracle@applecat orainstall]$ cd database
[oracle@applecat database]$ pwd
/home/orainstall/database
[oracle@applecat database]$ ls
doc install response runInstaller stage welcome.html
[oracle@applecat database]$ ./runInstaller
