CentOS 5安装Oracle 10g R2，准备安装的软件：（这个很重要，第一次安装失败就是因为软件包没有打全）。

一、基本条件
图形界面
能联网
最好不要启动selinux

二．准备安装的软件：（这个很重要，第一次安装失败就是因为软件包没有打全）
rpm -qa xxx*
yum install xxx
rpm -ivh xxx.rpm

rpm -qa binutils;
rpm -qa compat-libstdc++;
rpm -qa elfutils-libelf;
rpm -qa elfutils-libelf-devel;
rpm -qa glibc;
rpm -qa glibc-common;
rpm -qa glibc-devel;
rpm -qa gcc;
rpm -qa gcc-c++;
rpm -qa libaio;
rpm -qa libaio-devel;
rpm -qa libgcc;
rpm -qa libstdc++;
rpm -qa libstdc++-devel;
rpm -qa make;
rpm -qa sysstat;
rpm -qa unixODBC;
rpm -qa unixODBC-devel;

三．建立用户和组
groupadd oinstall
groupadd dba
useradd -g oinstall -G dba Oracle
passwd oracle

四．建立目录和权限
mkdir /oracle
mkdir /oracle/10g
chown -R oracle:oinstall /oracle

五．编辑变量
1.
vi /etc/sysctl.conf
kernel.shmall = 2097152
kernel.shmmax = 21474838
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default=4194304
net.core.rmem_max=4194304
net.core.wmem_default=262144
net.core.wmem_max=262144

kernel.shmall = 2097152
kernel.shmmax = 21474838 #根据实际情况进行修改，一般是内存的两倍
kernel.shmmni = 4096
# semaphores: semmsl, semmns, semopm, semmni
kernel.sem = 250 32000 100 128
fs.file-max = 6815744
fs.aio-max-nr = 1048576
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default=4194304
net.core.rmem_max=4194304
net.core.wmem_default=262144
net.core.wmem_max=10448756

2.
vi /etc/security/limits.conf
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536

3.
vi /etc/pam.d/login
session required /lib/security/pam_limits.so
session required pam_limits.so

4.
vi /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

5.
cd /home/oracle
vi .bash_profile
ORACLE_BASE=/oracle #可能要改的
ORACLE_HOME=$ORACLE_BASE/10g #可能要改的
ORACLE_SID=ORADB #可能要改的
PATH=$ORACLE_HOME/bin:$PATH

export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH

6.安装libXp
yum -y install libXp

7.
vi /etc/RedHat-release
将CentOS release 5 (Final) 修改成redhat 4

六．用oracle用户进入linux
Directions
1. Unzip the file: gunzip
2. Extract the file: cpio -idmv <
3. Installation guides and general Oracle Database 10g documentation can be found here.
4. Review the certification matrix for this product here.

乱码
这样做,也可以,在图形界面下开一个终端,
#>xhost +
#>su - oracle
#>unset LANG LANGUAGE
之后,在此终端内运行安装程序

进入终端
sh /ORACLE的目录/runInstaller
正常安装就可以，关于权限的错误可以忽略
