RHEL5_x64上安装Oracle 11.2

一:安装操作系统和补丁包
安装操作系统时只安装GNOME桌面
yum install gcc gcc-c++ libXp libaio make binutils openmotif setarch compat-db compat-gcc compat-gcc-c++ compat-libstdc++ compat-libstdc++-devel rsh　compat-libstdc++-33 elfutils-libelf-devel libaio-devel sysstat unixODBC unixODBC-devel pdksh

二：环境配置
1、创建Oracle安装目录
mkdir -p /u01/oracle/

2、创建用户账号
注意：安装Oracle数据库时必须使用非root用户，root用户被禁止安装
groupadd oinstall
groupadd dba
groupadd oper
groupadd asmadmin
useradd -u 500 -g oinstall -G dba,oper,asmadmin -d /u01/oracle oracle
passwd oracle      #设置oracle用户密码
chown -R oracle:oinstall /u01
chmod -R 775 /u01

3、配置用户环境
编辑/etc/profile .bash_profile 文件
export PS1="`/bin/hostname -s`-> "
export ORACLE_SID=wishdb
export ORACLE_BASE=/u01/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib
export PATH=$ORACLE_HOME/bin:$HOME/bin:/sbin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

编辑/etc/profile文件
if [ $USER = "oracle" ]; then
    if [ $SHELL = "/bin/ksh" ]; then
        ulimit -p 16384
        ulimit -n 65536
    else
        ulimit -u 16384 -n 65536
    fi
fi

4、配置内核参数
编辑/etc/sysctl.conf文件,添加以下内容.
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
net.ipv4.ipfrag_high_thresh = 524288
net.ipv4.ipfrag_low_thresh = 393216
net.ipv4.tcp_rmem = 4096 524288 16777216
net.ipv4.tcp_wmem = 4096 524288 16777216
net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_sack = 0
net.ipv4.tcp_window_scaling = 1
net.core.optmem_max = 524287
net.core.netdev_max_backlog = 2500
net.ipv4.tcp_mem = 16384 16384 16384
fs.file-max = 6815744
fs.aio-max-nr = 1048576
添加以上内容后必须刷新内核参数：sysctl -p

5、配置登录认证
编辑/etc/pam.d/login文件，添加以下内容,vi /etc/pam.d/login
session required /lib/security/pam_limits.so
session required pam_limits.so

6、配置limits.conf文件
编辑/etc/security/limits.conf文件，添加以下内容，vi /etc/security/limits.conf
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536

7、开始安装
