Oracle 11g for Linux CentOS 5.2 详细安装步骤分享(图解教程)_新手入门

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

#below for oracle11g
kernel.core_uses_pid = 1
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.shmall = 2097152
kernel.sem = 250 32000 100 128
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 262144
fs.file-max = 6553600
net.ipv4.ip_local_port_range = 1024 65000

//添加用户组及用户

执行如下命令：
#groupadd dba
#groupadd oinstall
#useradd oracle -g oinstall -g dba
#passwd oracle
//新建目录权限

执行如下命令：
#mkdir -p /u01
#chown -r oracle:dba /u01
#chmod -r 755 /u01
//用户环境变量

先切换用户到oracle:
su – oracle

修改.bash_profile文件：
vi .bash_profile

以下是此文件的内容：
# .bash_profile
# get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# user specific environment and startup programs
path=$path:home/bin
export oracle_base=/u01/app/oracle
export oracle_home=$oracle_base/product/11.1.0.6
export oracle_sid=sales
export path=$path:$oracle_home/bin:$oracle_home/apache/apache/bin
export tns_admin=$oracle_home/network/admin
export ld_library_path=$ld_library_path:oracle_home/lib
export nls_lang=american_america.zhs16gbk
export ora_nls10=$oracle_home/nls/data
unset username
umask 022

4、安装oracle
注销root ;

用oracle帐号进入，进入oracle所在的目录我的是/disk/oracle11g-linux_x86
[oracle@root-bs oracle11g-linux_x86]$ ls
doc install response runinstaller stage welcome.html
执行./runinsaller进行安装:

[oracle@root-bs oracle11g-linux_x86]$ ./runinstaller
