1.安装 CentOS 5.5 i386,全部默认安装,关闭SELinux,关闭防火墙。2.检查rpm包# rpm -qa --queryformat quot;%{NAME}-%{VERSIO

1.安装 CentOS 5.5 i386,全部默认安装,,关闭SELinux,关闭防火墙。

2.检查rpm包

# rpm -qa --queryformat "%{NAME}-%{VERSION}-%{RELEASE} (%{ARCH})\n"|\

egrep "binutils|compat-libstdc++|elfutils-libelf|gcc|glibc|kernel-headers|ksh|libaio|libgcc|libgomp|libstdc|make|sysstat|unixODBC|pdksh"|sort

安装rpm包,在光盘中放入CentOS55的DVD

执行以下命令(注,如所缺的不止这些包,请另行再安装,所要的包可以参考Oracle的标准安装文档)

mount -r -t iso9660 /dev/cdrom /media

cd /media/CentOS

rpm -ivh compat-libstdc++-33-3.2.3-61.i386.rpm

rpm -ivh elfutils-libelf-devel-0.137-3.el5.i386.rpm elfutils-libelf-devel-static-0.137-3.el5.i386.rpm

rpm -ivh libstdc++-devel-4.1.2-48.el5.i386.rpm

rpm -ivh kernel-headers-2.6.18-194.el5.i386.rpm

rpm -ivh glibc-headers-2.5-49.i386.rpm

rpm -ivh glibc-devel-2.5-49.i386.rpm

rpm -ivh libgomp-4.4.0-6.el5.i386.rpm

rpm -ivh glibc-devel-2.5-49.i386.rpm

rpm -ivh gcc-4.1.2-48.el5.i386.rpm

rpm -ivh gcc-c++-4.1.2-48.el5.i386.rpm

rpm -ivh libaio-devel-0.3.106-5.i386.rpm

rpm -ivh sysstat-7.0.2-3.el5.i386.rpm

rpm -ivh unixODBC-2.2.11-7.1.i386.rpm

rpm -ivh unixODBC-devel-2.2.11-7.1.i386.rpm

rpm -ivh pdksh-5.2.14-36.el5.i386.rpm

3.修改 /etc/inittab(非必要)

gedit /etc/inittab 或 nano /etc/inittab

找到

# Default runlevel. The runlevels used by RHS are:

# 0 - halt (Do NOT set initdefault to this)

# 1 - Single user mode

# 2 - Multiuser, without NFS (The same as 3, if you do not have networking)

# 3 - Full multiuser mode

# 4 - unused

# 5 - X11

# 6 - reboot (Do NOT set initdefault to this)

#

id:5:initdefault:

将 5 改成 3,即:

id:3:initdefault:

4.增加组及用户

groupadd oinstall

groupadd dba

useradd -g oinstall -G dba -d /u01/oracle oracle

chown -R oracle:oinstall u01

passwd oracle

检查 nobody 是否存在, id nobody

缺省存在的。如果不存在 # /usr/sbin/useradd -g nobody

5.调整内核参数

nano /etc/sysctl.conf

在最下面加入:

# by flexitime : install oracle 11g

fs.aio-max-nr = 1048576

fs.file-max = 6815744

kernel.shmall = 2097152

kernel.shmmax = 536870912

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

net.ipv4.ip_local_port_range = 9000 65500

net.core.rmem_default = 262144

net.core.rmem_max = 4194304

net.core.wmem_default = 262144

net.core.wmem_max = 1048586

-----------------

shmmax 的最少值是 0.5 GB. 但是Oracle推荐的值是 shmmax to 2.0 GB (2147483648) ,这会有更好的性能

6.为 oracle 用户设置 Shell 限制 (全部都是在文件的最下面加入)

nano /etc/security/limits.conf

# by flexitime : install oracle 11g

oracle soft nproc 2047

oracle hard nproc 16384

oracle soft nofile 1024

oracle hard nofile 65536

oracle soft stack 10240

nano /etc/pam.d/login

# by flexitime : install oracle 11g

session required pam_limits.so

nano /etc/profile

# by flexitime : install oracle 11g

if [ $USER = "oracle" ]; then

if [ $SHELL = "/bin/ksh" ]; then

ulimit -p 16384

ulimit -n 65536

else

ulimit -u 16384 -n 65536

fi

fi

nano /etc/csh.login

# by flexitime : install oracle 11g

if ( $USER == "oracle" ) then

limit maxproc 16384

limit deors 65536

endif

关闭SELINUX的工作模式(修改这一项后最好重启一下操作系统)

nano /etc/selinux/config

# by flexitime : install oracle 11g

SELINUX=disabled

nano /etc/RedHat-release

将CentOS release 5 (Final) 修改成

Red Hat Enterprise Linux AS release 5 (Taroon)

(因为oracle公司没推出CentOS版本的oracle)

su - oracle

cd ~

nano .bash_profile

# by flexitime : install oracle 11g

ORACLE_BASE=/u01

ORACLE_HOME=$ORACLE_BASE/oracle

ORACLE_SID=orcl

PATH=$ORACLE_HOME/bin:$PATH:$HOME/bin

export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH

7. 修改安装目录的权限

mv database /u01/

cd /u01

chown -R oracle:oinstall database/

8.使用oracle账号 登陆图形界面 进行安装

运行终端 Terminal

cd /u01/database

./runInstaller

linux
