1、检查内存、磁盘空间、系统版本：
[root@localhost ~]# grep MemTotal /proc/meminfo 
MemTotal:       515308 kB
[root@localhost ~]# grep SwapTotal /proc/meminfo 
SwapTotal:     1044216 kB
[root@localhost ~]# cat /proc/version 
Linux version 2.6.18-194.el5 ([email protected]) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-48)) #1 SMP Tue Mar 16 21:52:43 EDT 2010

2、检查软件包：
[root@localhost Server]# rpm -q --qf '%{NAME}-%{VERSION}-%{RELEASE} (%{ARCH})\n' \binutils elfutils-libelf elfutils-libelf-devel gcc gcc-c++ glibc glibc-common glibc-devel glibc-headers libaio libgcc libstdc++ make sysstat

libstdc++-4.1.2-48.el5 (i386)
make-3.81-3.el5 (i386)
sysstat-7.0.2-3.el5 (i386)

3、创建用户及用户组：
[root@localhost Server]# groupadd oinstall
[root@localhost Server]# groupadd dba
[root@localhost Server]# useradd -g oinstall -g dba -m oracle
[root@localhost Server]# 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.

4、内核修改：
[root@localhost Server]# vi /etc/sysctl.conf 
net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0

net.core.rmem_max = 1048576
net.core.wmem_default = 262144
net.core.wmem_max = 262144

net.core.rmem_max = 1048576
net.core.wmem_default = 262144
net.core.wmem_max = 262144
[root@localhost ~]# vi /etc/security/limits.conf

5、创建目录：
[root@localhost Server]# cd /opt
[root@localhost opt]# mkdir oracle
[root@localhost opt]# mkdir software
[root@localhost opt]# chown -R oracleinstall /opt/oracle/
[root@localhost opt]# chown -R oracleinstall software/
[root@localhost opt]# ls -l
total 16
drwxr-xr-x 2 oracle oinstall 4096 Sep  5 01:03 oracle
drwxr-xr-x 2 oracle oinstall 4096 Sep  5 01:12 software

6、开始安装：
[oracle@localhost database]$./runInstaller -silent -debug -force \
