4.安装依赖包
[iyunv@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
[iyunv@oracle11g ~]#

5.修改内核参数
[iyunv@oracle11g ~]# vim /etc/sysctl.conf
fs.file-max = 6815744
fs.aio-max-nr=1048576
kernel.shmall = 2097152
kernel.shmmax = 2147483648
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
[iyunv@oracle11g ~]# sysctl -p

6.用户对系统资源的限制
[iyunv@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
[iyunv@oracle11g ~]#

7.用户对shell的限制
[iyunv@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
[iyunv@oracle11g ~]#

8.添加用户登陆模块

[iyunv@oracle11g ~]# vim /etc/pam.d/login
session   required     /lib/security/pam_limits.so
session   required     pam_limits.so
[iyunv@oracle11g ~]#

9.主机与IP地址解析
[iyunv@oracle11g ~]# vim /etc/hosts
192.168.3.20   oracle11g

10.创建用户与用户组
[iyunv@oracle11g ~]# groupadd -g 500 oinstall
[iyunv@oracle11g ~]# groupadd -g 501 dba
[iyunv@oracle11g ~]# groupadd -g 502 oper
[iyunv@oracle11g ~]# useradd -u 500 -g oinstall -G dba,oper oracle
[iyunv@oracle11g ~]# chown  -R oracle:oinstall /home/oracle
[iyunv@oracle11g ~]# passwd oracle

[iyunv@oracle11g ~]# mkdir -p /u01/oracle/product/11.2.0.1/db_1
[iyunv@oracle11g ~]# chown -R oracle:oinstall /u01
[iyunv@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
[iyunv@oracle11g ~]# . /home/oracle/.bash_profile

12.解压oracle 11g软件并安装
[iyunv@oracle11g ~]# xhost +
access control disabled, clients can connect from any host
[iyunv@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
