RHEL5.8安装Oracle11g

1、安装环境
[root@rusky-oracle11g ~]# uname -r
2.6.18-308.el5
[root@rusky-oracle11g ~]# cat /etc/issue
Red Hat Enterprise Linux Server release 5.8 (Tikanga)
Kernel \r on an \m
[root@rusky-oracle11g ~]# uname -a
Linux rusky-oracle11g.com 2.6.18-308.el5 #1 SMP Fri Jan 27 17:17:51 EST 2012 x86_64 x86_64 x86_64 GNU/Linux

2、主机名及IP设置为如下
[root@localhost local_repo]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
192.168.1.201 rhel201.com rhel201

[root@localhost local_repo]# cat /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=yes
HOSTNAME=rhel201.com

[root@localhost local_repo]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
# Intel Corporation 82545EM Gigabit Ethernet Controller (Copper)
DEVICE=eth0
BOOTPROTO=static
DHCPCLASS=
HWADDR=00:0C:29:C5:02:E2
ONBOOT=yes
IPADDR=192.168.1.201
NETMASK=255.255.255.0
GATEWAY=192.168.1.1

3、关闭selinux及防火墙
[root@rusky-oracle11g ~]# cat /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - SELinux is fully disabled.
SELINUX=disabled
# SELINUXTYPE= type of policy in use. Possible values are:
# targeted - Only targeted network daemons are protected.
# strict - Full SELinux protection.
SELINUXTYPE=targeted

关闭防火墙：
[root@rusky-oracle11g ~]#chkconfig iptables off
[root@rusky-oracle11g ~]#service iptables stop

3、内核及其它相关参数设置
[root@rusky-oracle11g ~]# cat /etc/security/limits.conf
# /etc/security/limits.conf
#
#Each line describes a limit for a user in the form:
#
#<domain> <type> <item> <value>
#
#Where:
#<domain> can be:
# - an user name
# - a group name, with @group syntax
# - the wildcard *, for default entry
# - the wildcard %, can be also used with %group syntax,
# for maxlogin limit
#
#<type> can have the two values:
# - "soft" for enforcing the soft limits
# - "hard" for enforcing hard limits
#
#<item> can be one of the following:
# - core - limits the core file size (KB)
# - data - max data size (KB)
# - fsize - maximum filesize (KB)
# - memlock - max locked-in-memory address space (KB)
# - nofile - max number of open files
# - rss - max resident set size (KB)
# - stack - max stack size (KB)
# - cpu - max CPU time (MIN)
# - nproc - max number of processes
# - as - address space limit
# - maxlogins - max number of logins for this user
# - maxsyslogins - max number of logins on the system
# - priority - the priority to run user process with
# - locks - max number of file locks the user can hold
# - sigpending - max number of pending signals
# - msgqueue - max memory used by POSIX message queues (bytes)
# - nice - max nice priority allowed to raise to
# - rtprio - max realtime priority
#
#<domain> <type> <item> <value>
#

#* soft core 0
#* hard rss 10000
#@student hard nproc 20
#@faculty soft nproc 20
#@faculty hard nproc 50
#ftp hard nproc 0
#@student - maxlogins 4
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 4096
oracle hard nofile 65536
oracle soft stack 10240
# End of file

 /sbin/sysctl -p 执行这条命令使配置生效

[root@rusky-oracle11g ~]# cat /etc/pam.d/login
#%PAM-1.0
auth [user_unknown=ignore success=ok ignore=ignore default=bad] pam_securetty.so
auth include system-auth
account required pam_nologin.so
account include system-auth
password include system-auth
# pam_selinux.so close should be the first session rule
session required pam_selinux.so close
session optional pam_keyinit.so force revoke
session required pam_loginuid.so
session include system-auth
session optional pam_console.so
# pam_selinux.so open should only be followed by sessions to be executed in the user context
session required pam_selinux.so open

session required pam_limits.so

4、安装所需的包
配置本地yum源，使用yum命令安装所需包。参考链接：http://www.cnblogs.com/rusking/p/4248946.html
The following or later version of packages for Asianux 3, Oracle Linux 5, and Red Hat Enterprise Linux 5 must be installed:

binutils-2.17.50.0.6
compat-libstdc++-33-3.2.3
compat-libstdc++-33-3.2.3 (32 bit)
elfutils-libelf-0.125
elfutils-libelf-devel-0.125
gcc-4.1.2
gcc-c++-4.1.2
glibc-2.5-24
glibc-2.5-24 (32 bit)
glibc-common-2.5
glibc-devel-2.5
glibc-devel-2.5 (32 bit)
glibc-headers-2.5
ksh-20060214
libaio-0.3.106
libaio-0.3.106 (32 bit)
libaio-devel-0.3.106
libaio-devel-0.3.106 (32 bit)
libgcc-4.1.2

libstdc++-4.1.2
libstdc++-4.1.2 (32 bit)
libstdc++-devel 4.1.2
make-3.81
sysstat-7.0.2
还要下面这三个包也安装：
On Asianux Server 3, Oracle Linux 5, and Red Hat Enterprise Linux 5:
unixODBC-2.2.11 (32-bit) or later
unixODBC-devel-2.2.11 (64-bit) or later
unixODBC-2.2.11 (64-bit) or later

最好重启机器，以确保之前配置的相关内容生效。

5、创建用户及组
groupadd oinstall
groupadd dba
groupadd oper
useradd -g oinstall -G dba,oper oracle
passwd oracle

6、创建安装目录及授权
Create the directories in which the Oracle software will be installed.

mkdir -p /u01/app/oracle/product/11.2.0.4/db_1
chown -R oracle:oinstall /u01
chmod -R 775 /u01
If you are using X Emulation, login as root and issue the following command.

xhost +

7、设置oracle用户环境变量
Login as the oracle user and add the following lines at the end of the "/home/oracle/.bash_profile" file.
以oracle用户登录添加如下内容到这个文件：/home/oracle/.bash_profile(注意修改红色部分内容)
# Oracle Settings
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR

ORACLE_HOSTNAME=rhel201.com; export ORACLE_HOSTNAME
ORACLE_UNQNAME=orcl; export ORACLE_UNQNAME
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0.1/db_1; export ORACLE_HOME
ORACLE_SID=orcl; export ORACLE_SID
ORACLE_TERM=xterm; export ORACLE_TERM
PATH=/usr/sbin:$PATH; export PATH
PATH=$ORACLE_HOME/bin:$PATH; export PATH

LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH

===================================
修改系统环境变量/etc/profile
修改环境变量/etc/profile，加入以下内容

if [ $USER = "oracle" ]; then

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

ulimit -p 16384

ulimit -n 65536

else
ulimit -u 16384 -n 65536
fi
fi
8、执行安装
installation

Log into the oracle user. If you are using X emulation then set the DISPLAY environmental variable.

[root@rusky-oracle11g ~]#DISPLAY=192.168.1.201:0.0; export DISPLAY

或者是以root用户登录，执行该命令：xhost +

切换到oracle用户，输入命令：xclock,正常的话会出现图形界面的时钟。之后，可执行./runInstaller在图形界面安装Oracle。
Start the Oracle Universal Installer (OUI) by issuing the following command in the database directory.

./runInstaller DISPLAY报错处理：http://www.cnblogs.com/rusking/p/4232835.html

《参数文档： http://oracle-base.com/articles/11g/oracle-db-11gr2-installation-on-oracle-linux-7.php》

9、安装报错

9.1 During the link phase you will encounter an error invoking the "ins_emagent.mk" file. To fix this, edit the "$ORACLE_HOME/sysman/lib/ins_emagent.mk", doing a search and replace for the line shown below.

FROM:
$(MK_EMAGENT_NMECTL)
TO  :
$(MK_EMAGENT_NMECTL) -lnnz11

Click the "Retry" button.

9.2 安装过程中-检查环境缺少pdksh包，忽略即中

Proceed with the installation of your choice. You can see type of installation I performed by clicking on the links below to see screen shots of each stage. The "pdksh" package will be listed as missing, which can be ignored because we installed the "ksh" package instead.
