redhat 6.4安装oracle11g单机

概述：学习oracle首先需要将oracle安装在操作系统后，您才可以继续其他方面的学习；本文就oracle11g在redhat6.4上使用本地卷管理的方式进行简单安装说明；官方文档请查看：https://docs.oracle.com/cd/E11882_01/install.112/e47689/toc.htm

实验步骤：

1、操作系统准备

1.1、相关包安装

1.2、相关系统参数修改

1.3、关闭防火墙

2、新建相关用户：oracle

3、新建相关目录并修改权限

4、配置oracle用户环境变量

5、安装oracle软件和使用dbca建库

实验：

解压安装介质：11.2.0.4oracle安装包

[[email protected] ~]# cd /tmp/
[[email protected] tmp]# ls
keyring-bzLfgY p13390677_112040_LINUX_1of7.zip pulse-l84Sn5PAruWy virtual-root.O43zXP
orbit-gdm p13390677_112040_LINUX_2of7.zip rhel-server-6.4-x86_64-dvd.iso virtual-root.qyE84j

[[email protected] tmp]# unzip p13390677_112040_LINUX_1of7.zip
[[email protected] tmp]# unzip p13390677_112040_LINUX_2of7.zip

操作系统参数修改：

[[email protected] tmp]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.1.66 cube

[[email protected] tmp]# 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 - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
SELINUXTYPE=targeted

[[email protected] tmp]# service iptables stop
iptables: Flushing firewall rules: [ OK ]
iptables: Setting chains to policy ACCEPT: filter [ OK ]
iptables: Unloading modules: [ OK ]
[[email protected] tmp]# chkconfig iptables off

[[email protected] tmp]# vi /etc/sysctl.conf --- 添加

fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 4294967295
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 = 1048576

[[email protected] tmp]# sysctl -p --生效参数

[[email protected] tmp]# vi /etc/security/limits.conf ---添加

oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536

[[email protected] tmp]# vi /etc/pam.d/login ---添加
session required /lib64/security/pam_limits.so
session required pam_limits.so

[[email protected] tmp]# vi /etc/profile --添加

if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi

oracle需求的包安装

[[email protected] tmp]# mount /dev/cdrom /media/
mount: block device /dev/sr0 is write-protected, mounting read-only
[[email protected] tmp]# yum install -y 相关包后续提示缺少包就相应的补上就行

新建用户oracle：

[[email protected] tmp]# groupadd -g 2000 oinstall
[[email protected] tmp]# groupadd -g 2001 dba
[[email protected] tmp]# useradd -u 1000 -g oinstall -G dba oracle
[[email protected] tmp]# passwd oracle

新建相关目录及修改权限

[[email protected] tmp]# mkdir -p /u01/app/oracle
[[email protected] tmp]# chown -R oracle:oinstall /u01/
[[email protected] tmp]# chmod -R 755 /u01/

修改oracle用户参数文件：

[[email protected] tmp]# vi /home/oracle/.bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin
