Oracle 11g for Linux CentOS 5.2 详细安装步骤分享(图解教程)-木庄网络博客

本文整理自网络，侵删。

首先在oracle官方上下载一个oracle 11g(特别说明一下在安装CentOS 5.2时尽量是把开发包装全一些，这样您在安装包检测的时候就会少装一些包。还有一点：安装大概需要5G多的空间，空间不够就老是出错。)

1、用unzip解压 Oracle 11g文件

unzip linux_x86_11gR1_database.zip

(这个您也可以在Windows下面解压，不过您要加载过来，如果你的分区是NTFS，那您就要安装kernel-module-ntfs、fuse、ntfs-3g,当然具体的怎么操作就不必多说了。如果您还是搞不定的话，请给QQ：42271520留言。)

2、安装包检测及安装

在终端中执行： rpm -q gcc make binutils setarch compat-db compat-gcc compat-gcc-c++ compat-libstdc++ compat-libstdc++-devel unixODBC unixODBC-devel libaio-devel sysstat
显示结果如下：

vel sysstat

gcc-4.1.2-42.el5

make-3.81-3.el5

binutils-2.17.50.0.6-6.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

unixODBC-2.2.11-7.1

package unixODBC-devel is not installed

package libaio-devel is not installed

package sysstat is not installed

分析：

上面package 软件包 is not installed 部分说明此软件包没有安装，您可以再光盘里面找，再用rpm -ivh 安装就行，这些包在centos安装盘中都用；或者直接用yum install 软件包来安装，具体操作如下：

yum install compat-db

安装成功Installed: compat-db.i386 0:4.2.52-5.1 Complete!

yum install compat* (这个包比较多，要稍等一会，不急先抽根烟吧。)

安装成功 Installed: compat*......... Complete!

yum install unixODBC-devel

安装成功 Installed: unixODBC-devel.i386 0:2.2.11-7.1 Complete!

yum install libaio-devel

安装成功 Installed: libaio-devel.i386 0:0.3.106-3.2 Complete!

yum install sysstat

安装成功 Installed: sysstat.i386 0:7.0.2-1.el5 Complete!

说明：您可以再执行一次rpm -q 软件包组合具体如下：

gcc-4.1.2-42.el5

make-3.81-3.el5

binutils-2.17.50.0.6-6.el5

setarch-2.0-1.1

compat-db-4.2.52-5.1

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

unixODBC-2.2.11-7.1

unixODBC-devel-2.2.11-7.1

libaio-devel-0.3.106-3.2

sysstat-7.0.2-1.el5

如上所述：还是有4个软件包没有安装，这个不用理会，其实我们刚才安装的compat包已经包含了；可以继续下一步了。

3、系统参数和用户及目录设置
//系统参数设置
vi /etc/sysctl.conf

以下为此文件更改后的内容：

# Kernel sysctl configuration file for Red Hat Linux
#
# For binary values, 0 is disabled, 1 is enabled.See sysctl(8) and
# sysctl.conf(5) for more details.

# Controls IP packet forwarding
net.ipv4.ip_forward = 0

# Controls source route verification
net.ipv4.conf.default.rp_filter = 1

# Do not accept source routing
net.ipv4.conf.default.accept_source_route = 0

# Controls the System Request debugging functionality of the kernel
kernel.sysrq = 0

# Controls whether core dumps will append the PID to the core filename
# Useful for debugging multi-threaded applications
kernel.core_uses_pid = 1

# Controls the use of TCP syncookies
net.ipv4.tcp_syncookies = 1

# Controls the maximum size of a message, in bytes
#kernel.msgmnb = 65536

# Controls the default maxmimum size of a mesage queue
#kernel.msgmax = 65536

# Controls the maximum shared segment size, in bytes
#kernel.shmmax = 4294967295

# Controls the maximum number of shared memory segments, in pages
#kernel.shmall = 268435456
