数据库软件版本	oracle 11.2.0.4	oracle 11.2.0.4
ORACLE_BASE	/u01/app/oracle	/u01/app/oracle
ORACLE_HOME	/u01/app/oracle/product/11.2.0/db_1	/u01/app/oracle/product/11.2.0/db_1
ORACLE_SID	orcl	lorcl

二、数据库安装

1. 基础参数设置

[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0

[root@localhost ~]# vi /etc/hosts

[root@localhost ~]# /etc/init.d/iptables stop

[root@localhost ~]# chkconfig iptables off

[root@localhost ~]# vi /etc/pam.d/login

session    required     /lib64/security/pam_limits.so

[root@localhost ~]# vi /etc/selinux/config

SELINUX=disabled

[root@localhost ~]# vi /etc/security/limits.conf

oracle           soft    nproc           2047

oracle           hard    nproc           16384

oracle           soft    nofile          1024

oracle           hard    nofile          65536

[root@localhost ~]# vi /etc/sysctl.conf

fs.aio-max-nr = 1048576

fs.file-max = 6815744

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

[root@localhost ~]# sysctl -p

[root@localhost ~]# vi /etc/profile

if [ $USER = "oracle" ]; then

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

ulimit -p 16384

ulimit -n 65536

else

ulimit -u 16384 -n 65536

fi

fi

2. 创建用户和组，设置环境变量

[root@localhost ~]# groupadd oinstall

[root@localhost ~]# groupadd dba

[root@localhost ~]# groupadd oper   

[root@localhost ~]# useradd -g oinstall -G dba,oper oracle

[root@localhost ~]# passwd oracle

[root@localhost ~]# su - oracle

[oracle@localhost ~]$ vi .bash_profile

ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE

ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1; export ORACLE_HOME

ORACLE_SID=orcl; export ORACLE_SID

ORACLE_TERM=xterm; export ORACLE_TERM

PATH=$ORACLE_HOME/bin:$PATH; export PATH

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib; export LD_LIBRARY_PATH

CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib;

export CLASSPATH

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

使环境变量生效

[oracle@localhost ~]$ source .bash_profile

3. 配置本地 yum 源

[root@localhost ~]# umount /dev/cdrom

[root@localhost ~]# mount /dev/cdrom /mnt/

mount: block device /dev/sr0 is write-protected, mounting read-only

[root@localhost ~]# mount -o remount,rw /dev/cdrom /mnt/cdrom

[root@localhost ~]# cd /etc/yum.repos.d/

[root@localhost ~]# mv CentOS-Base.repo CentOS-Base.repo.bak

[root@localhost ~]# mv CentOS-Debuginfo.repo CentOS-Debuginfo.repo.bak

[root@localhost ~]# mv CentOS-Vault.repo CentOS-Vault.repo.bak

[root@localhost  yum.repos.d]# vi /etc/yum.repos.d/CentOS-Media.repo

         [c6-media]

name=CentOS-$releasever - Media

baseurl=file:///mnt/

gpgcheck=0

enabled=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

[root@localhost  yum.repos.d]# yum clean all

[root@localhost  yum.repos.d]# yum list

[root@localhost yum.repos.d]# yum -y install binutils compat-libcap1 compat-libstdc* gcc gcc-c++* glibc glibc-devel ksh libgcc libstdc libaio libaio-devel make elfutils-libelf-devel sysstat

[root@strong ~]# chown -R oracle.oinstall /u01
