1. groupadd dba
   

   groupadd oinstall

   useradd -g oinstall -G dba oracle

   passwd oracle

2. mkdir /opt/oracle -pv

   chown -R oracle.oinstall /opt/oracle

3. 检查依赖包：

   binutils

   compat-libstdc

   gcc

   gcc-c++

   glibc

   glibc-common

   glibc-devel

   glibc-headers

   kernel-headers

   ksh

   libaio

   libaio-devel

   libgcc

   libgomp

   libstdc++

   libstdc++44-devel

   make

   numactl-devel

   sysstat

   unixODBC

   unixODBC-devel

4. 安装java
   

   jdk-1_5_0_06-linux-i586.bin

   sh jdk-1_5_0_06-linux-i586.bin

   cp -rv jdk-1_5_0_06 /usr/local

   ln -s /usr/local/jdk-1_5_0_06/ /usr/local/jdk
   

   ln -s /usr/local/jdk-1_5_0_06/jre /usr/local/jre

   ln -s /usr/local/jdk-1_5_0_06/bin/java /usr/bin/java

   ln -s /usr/local/jdk-1_5_0_06/bin/javac /usr/bin/javac

5. 配置Java环境变量

   cd /etc/profile.d

   vi java.sh

   export JAVA_HOME=/usr/local/jak

   export PATH=$PATH:$JAVA_HOME/bin
   

   export CLASSPATH=$JAVA_HOME/lib/tools.tar:.:$JAVA_HOME/lib/dt.jar

6. 系统配置

   chkconfig iptables off

   selinux=disabled

7. 内核配置

   oracle soft nproc 2047
   

   oracle soft nofile 1024
   

   oracle hard nproc 16384
   

   oracle hard nofile 65536

8. 内核优化参数

   vi /etc/sysctl.conf

   
   

   net.ipv4.ip_forward= 0
   

   net.ipv4.conf.default.rp_filter = 1

   net.ipv4.conf.default.accept_source_route =0

   kernel.sysrq = 0

   kernel.core_uses_pid = 1

   net.ipv4.tcp_syncookies = 1

   net.ipv4.ip_local_port_range = 1024 65500

   kernel.msgmnb = 65536

   kernel.msgmax = 65536

   kernel.shmmax = 4294967295

   kernel.shmall = 268435456

   kernel.shmmni = 4096

   kernel.sem = 250 32000 100 128

   fs.file-max = 65536

   net.core.rmem_default = 262144

   net.core.rmem_max = 262144

   net.core.wmem_deault = 262144

   net.core.wmem_max = 262144

9. 配置oracle环境变量

   
   export TMP=/tmp
   export TMPDIR=$TMP
   export ORACLE_BASE=/opt/oracle
   export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1
   export ORACLE_SID=orcl
   export ORACLE_TERM=xterm
   export PATH=/usr/sbin:$PATH
   export PATH=$ORACLE_HOME/bin:$PATH
   export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
   export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib:$ORACLE_HOME/network/jlib
   export DISPLAY=:0.0
   export ORA_NLS33=$ORACLE_HOME/ocommon/nls/admin/data

   ###############################################################################
   ###set jdk environment
   JAVA_HOME=/usr/local/jdk;export JAVA_HOME
   #PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/lib/i386:$HOME/bin:/home/oracle/bin:/opt/oracle/product/11.2.0/bin;export PATH
   PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/lib/i386:/home/oracle/bin:$ORACLE_HOME/bin ;export PATH

   LC_ALL=zh_CN
   LANG=zh_CN.GB2312
   umask 022
   #
   if [ $USER = "oracle" ]; then
   if [ $SHELL = "/bin/ksh" ];then
   ulimit -p 16384
   ulimit -n 65536
   else
   ulimit -u 16384 -n 65536
   fi
   fi

10. 开始安装

xhost local:oracle non-network localconnections being added to access control list

11. su - oracle

cd /opt/oracle/database

export LANG=c

./runinstaller
