【前言】
目的：安装64 bIT Oracle10g
环境：RHEL 5.2 64 bit 操作系统
【步骤】：
1、安装RHEL操作系统，下载并上传介质
2、创建软件安装环境
3、安装依赖包
4、检查修改系统参数
5、安装Oracle软件
6、创建数据库实例
1、安装RHEL操作系统，下载并上传介质
RHEL安装过程可以参考我的另一篇文章，详细这里不做叙述，安装并上传介质后，如下：

[root@Fantasy install]# cpio -idmv 10201_database_linux_x86_64.cpio
解压后：

2、创建软件安装环境
2.1、创建Oracle相关账号以及目录：
Code highlighting produced by Actipro CodeHighlighter (freeware)>[root@Fantasy ~]# groupadd oinstall
[root@Fantasy ~]# groupadd dba
[root@Fantasy ~]# useradd -g oinstall -G dba oracle
[root@Fantasy ~]# 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@Fantasy opt]# id oracle
uid=501(oracle) gid=501(oinstall) groups=501(oinstall),502(dba)
[root@Fantasy ~]# mkdir -p /opt/oracle/10g/db_1
[root@Fantasy ~]# cd /opt
[root@Fantasy opt]# ls -lrt
total 4
drwxr-xr-x 3 root root 4096 May 15 23:32 oracle
[root@Fantasy opt]# chown -R oracle:oinstall oracle/
2.1、增加Oracle相关的环境变量，修改/home/oracle/.bash_profile文件，增加下面内容：
Code highlighting produced by Actipro CodeHighlighter (freeware)>export ORACLE_BASE=/opt/oracle
export ORACLE_HOME=$ORACLE_BASE/10g/db_1
export ORACLE_SID=orc
export LD_LIBRARY_PATH=$ORACLE_HOME/bin:/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin/
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
export TEMP=/tmp
export TMP=/tmp
export TMPDIR=/tmp
export umask=022
export LANG=en_US
PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin
export PATH
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
3、安装依赖包

compat-db-4.1.25-9.x86_64.rpm
control-center-2.8.0-12.x86_64.rpm
gcc-3.4.3-22.1.x86_64.rpm
gcc-c++-3.4.3-22.1.x86_64.rpm

glibc-devel-2.3.4-2.9.i386.rpm
libXp-1.0.0-8.1.el5.rpm
4、检查修改系统参数
4.1、检查内存和交换分区的大小，如果内存大于1G，交换分区一般是内存的2倍
Code highlighting produced by Actipro CodeHighlighter (freeware)>[root@Fantasy /]# grep MemTotal /proc/meminfo
MemTotal: 1027060 kB
[root@Fantasy /]# grep SwapTotal /proc/meminfo
SwapTotal: 2097144 kB
[root@Fantasy /]#
4.2、 修改内核参数，修改文件：/etc/sysctl.conf，增加下面内容：
Code highlighting produced by Actipro CodeHighlighter (freeware)>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
执行命令：/sbin/sysctl -p，令修改生效，，
4.3、查看/etc/pam.d/login文件是否有下面选项(如果没有则添加)：
session required /lib/security/pam_limits.so
pam_limits.so是linux 中的一个PAM（插入式认证模块，Pluggable Authentication Modules），
其配置文件是/etc/sysctl.conf，用于分配用户登录后的权限
4.4、修改文件/etc/security/limits.conf，增加下面内容：

oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
