[root@oracle11g ~]# vim /etc/yum.repos.d/CentOS-Base.repo 

baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/ --这行全部取消注释

[root@oracle11g ~]# yum repolist

[root@oracle11g ~]# 


4.安装依赖包

[root@oracle11g ~]# yum install -y binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel gcc gcc-c++ glibc glibc-common glibc-devel libaio libaio-devel libgcc libstdc++ libstdc++-devel make numactl sysstat libXp unixODBC unixODBC-devel -y

[root@oracle11g ~]#


5.修改内核参数

[root@oracle11g ~]# vim /etc/sysctl.conf

fs.file-max = 6815744

fs.aio-max-nr=1048576

kernel.shmall = 2097152

kernel.shmmax = 4127434752

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@oracle11g ~]# sysctl -p


6.用户对系统资源的限制

[root@oracle11g ~]# vim /etc/security/limits.conf

oracle  soft  nproc  2047

oracle  hard  nproc  16384

oracle  soft  nofile  1024

oracle  hard  nofile  65536

oracle  soft  stack  10240

[root@oracle11g ~]#


7.用户对shell的限制

[root@oracle11g ~]# vim /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

[root@oracle11g ~]#


8.添加用户登陆模块

[root@oracle11g ~]# vim /etc/pam.d/login 

session   required     /lib/security/pam_limits.so

session   required     pam_limits.so

[root@oracle11g ~]#


9.主机与IP地址解析

[root@oracle11g ~]# vim /etc/hosts

192.168.3.20   oracle11g


10.创建用户与用户组

[root@oracle11g ~]# groupadd -g 500 oinstall

[root@oracle11g ~]# groupadd -g 501 dba

[root@oracle11g ~]# groupadd -g 502 oper

[root@oracle11g ~]# useradd -u 500 -g oinstall -G dba,oper oracle

[root@oracle11g ~]# chown  -R oracle:oinstall /home/oracle

[root@oracle11g ~]# passwd oracle

Changing password for user oracle.

New password: 

BAD PASSWORD: it is based on a dictionary word

BAD PASSWORD: is too simple

Retype new password: 

passwd: all authentication tokens updated successfully.

[root@oracle11g ~]#


11.创建所需要要的目录和设置环境变量

[root@oracle11g ~]# mkdir -p /u01/oracle/product/11.2.0.1/db_1

[root@oracle11g ~]# chown -R oracle:oinstall /u01

[root@oracle11g ~]# vim /home/oracle/.bash_profile

export ORACLE_BASE=/u01/oracle

export ORACLE_HOME=$ORACLE_BASE/product/11.2.0.1/db_1

export ORACLE_SID=orac11g

export PATH=$ORACLE_HOME/bin:$PATH

[root@oracle11g ~]# . /home/oracle/.bash_profile 


12.解压oracle 11g软件并安装

[root@oracle11g ~]# xhost +

access control disabled, clients can connect from any host

[root@oracle11g ~]# su - oracle

[oracle@oracle11g ~]$ unzip linux.x64_11gR2_database_1of2.zip 

[oracle@oracle11g ~]$ unzip linux.x64_11gR2_database_2of2.zip 

[oracle@oracle11g ~]$ cd database/

[oracle@oracle11g database]$ ./runInstaller
