CentOS release 6.6 (Final)
Kernel 2.6.32-504.el6.x86_64
Oracle版本：
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
1.安装Oracle前期准备：
1.1配置网络和主机名vim /etc/sysconfig/network-scripts/ifconfig
按字母【i】进入编辑模式，并修改配置文件
【Esc】退出编辑模式，输入【:wq】保存退出
重启网络服务service network restart
查看网络是否正常ifconfig
vim /etc/sysconfig/network

1.2关闭防火墙
重启生效：chkconfig --level 345 iptables off
立刻生效：service iptables stop
1.3关闭Selinux(需要重启才能生效)vim /etc/selinux/config
将框中的enforcing修改为disabled，【:wq】保存退出
1.4重启系统：init 6
1.5Vmware网卡配置
1.6验证主机和CentOS虚拟机是否能相互访问
真机：ping 192.168.1.11
虚拟机：ping 192.168.1.10
1.7配置YUM源
备份：cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak
编辑：vim /etc/yum.repos.d/CentOS-Base.repo
[base]
name=CentOS-$releasever - Base
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra
baseurl=file:///mnt/
gpgcheck=0
enabled=1
【:wq】保存退出
1.8挂载系统光盘镜像，安装rpm包
编辑shell文件：vi ~/pack.sh
#!/bin/bash
#start install required packages
echo "start installing required packages"
yum -y install binutils-*
yum -y install compat-libstdc++-*
yum -y install elfutils-libelf-*

yum -y install gcc-c++-*
yum -y install glibc-*
yum -y install glibc-common-*
yum -y install glibc-devel-*
yum -y install glibc-headers-*
yum -y install libaio-*
yum -y install libaio-devel-*
yum -y install libgcc-*
yum -y install libstdc++-*
yum -y install libstdc++-devel*
yum -y install make-*
yum -y install sysstat-*

yum -y install nscd-*
yum -y install mpfr-*
yum -y install ppl-*
yum -y install cloog-ppl-*
yum -y install cpp-*
yum -y install libXext-*
yum -y install ksh-*
赋予执行权限：chmod +x ~/pack.sh
挂载光盘到/mnt目录下：mount /dev/cdrom /mnt/
提示信息“mount: block device /dev/sr0 is write-protected, mounting read-only”
1.9安装必需的rpm包：cd /mnt/Packages
~/pack.sh
安装过程中的部分截图
1.10拷贝Oracle压缩包到Linux并解压
cd /oraPKG
unzip linux.x64_11gR2_database_1of2.zip
unzip linux.x64_11gR2_database_2of2.zip
1.11创建用户，组
groupadd oinstall
groupadd dba
groupadd oper
groupadd asmadmin
groupadd asmdba
groupadd asmoper
useradd -g oinstall -G dba,oper,asmdba oracle
passwd oracle
输入Oracle用户的密码；
1.12建立挂载点根据实际情况建立(注意后面设置环境变量时也需要做相应的修改)
mkdir -p /u01/app/oracle
chown -R oracle:oinstall /u01/app/oracle
chmod -R 777 /u01/
1.13修改内核参数cat >> /etc/sysctl.conf <
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 1073741824
kernel.shmmni = 4096

net.core.wmem_default = 262144
net.core.wmem_max = 1048586
EOFsysctl -p
modprobe bridge
lsmod |grep bridge
1.14修改用户资源限制
cat >>/etc/security/limits.conf <
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
EOF
1.15修改系统环境
cat >>/etc/profile <
if [ $USER = "oracle" ] || [ $USER = "grid" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
umask 022
fi
export PATH=$PATH:/u01/app/11.2.0/grid/bin
EOF
1.16修改用户环境
su - oracle
cat >> ~/.bash_profile <
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_HOSTNAME=sinosoftDB1 #需要与主机名一致，否则报错
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
export ORACLE_SID=orcl #需要和后面安装时填的一致，否则无法启动数据库
export ORACLE_TERM=xterm
export PATH=/u01/app/oracle/product/11.2.0/db_1/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=/u01/app/oracle/product/11.2.0/db_1/JRE:/u01/app/oracle/product/11.2.0/db_1/jlib:/u01/app/oracle/product/11.2.0/db_1/rdbms/jlib
EOF
立即生效bash_profilesource .bash_profile
2.图形界面安装
2.1配置XShell
以root用户登录：xhost +
提示信息“access control disabled, clients can connect from any host”
切换到oracle用户
su – oracle
export LANG=en_US
export DISPLAY=192.168.1.10:0.0 IP为真机的地址
cd /oraPKG/database/
./runInstaller
2.2然后等待弹出Oracle的安装界面
如果没有安装，安装完成后再点击Next
看到以下界面则说明Oracle客户端已经安装成功了，正在安装数据库。
至此Oracle的安装就算完成了。
