一、运行环境 
 
注意:Oracle11安装的SWAP需要在2.57G以上,,因此在安装CentOS时候,确保swap大于2.57G
 
系统环境:centos 5.6 32位(图形安装)
 硬盘分区:
 /boot 150M
 swap 4096M(最少要3G以上)
 / 10G
 /home 5G
 /tmp 5G
 /usr 10G
 /usr/local 10G

二、安装oracle 11gR2 依赖的组件包
 #需要以下组件:

 /sbin/ldconfig
 
三、调整内核参数
 vi /etc/sysctl.conf
 fs.file-max = 6815744
 kernel.shmall = 2097152
 kernel.shmmax = 536870912
 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
 fs.aio-max-nr = 1048576
 
#让内核参数生效
 sysctl -p
 
#修改limits.conf
 vi /etc/security/limits.conf
 #oracle settings
 oracle          soft    nproc  2047
 oracle          hard    nproc  16384
 oracle          soft    nofile  1024
 oracle          hard    nofile  65536
 
#修改系统版本(RedHat 5.×系列系统略过这步)
 cp /etc/redhat-release /etc/redhat-release.bk
 vi /etc/redhat-release
 #修改内容为:
 Red Hat Enterprise Linux AS release 5 (Taroon)
 
#修改/etc/pam.d/login
 #添加以下内容:
 session    required    /lib/security/pam_limits.so
 session    required    pam_limits.so
 
#修改/etc/profile
 vi /etc/profile
 #添加以下内容:
 if [ $USER = "oracle" ]; then
    if [ $SHELL = "/bin/ksh" ]; then
      ulimit -p 16384
      ulimit -n 65536
    else
      ulimit -u 16384 -n 65536
    fi
 fi
 
#修改/etc/csh.login
 vi /etc/csh.login
 #添加以下内容:
 if ( $USER == "oracle" ) then
      limit maxproc 16384
      limit deors 65536
 endif
 
四、创建oracle用户
 groupadd oinstall
 groupadd dba
 useradd -g oinstall -G dba oracle
 passwd oracle    #753951
 
mkdir -p /data/oracle
 mkdir -p /data/oralnventory
 mkdir -p /data/software
 chown -R oracle:oinstall /data/oracle
 chown -R oracle:oinstall /data/software
 chown -R oracle:oinstall /data/oralnventory
 
#设置用户环境变量
 #su - oracle
 $ vi .bash_profile
 #添加以下内容:
 ORACLE_SID=kerry; export ORACLE_SID
 ORACLE_BASE=/data/oracle; export ORACLE_BASE
 ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1; export ORACLE_HOME
 PATH=$PATH:$ORACLE_HOME/bin:$HOME/bin; export PATH
 
ORACLE_BASE下是admin和product
 ORACLE_HOME下则是ORACLE的命令、连接库、安装助手、listener等等一系列的东东。
 这只是ORACLE自己的定义习惯。ORACLE_HOME比ORACLE_BASE目录要更深一些。也就是说:ORACLE_HOME=$ORACLE_BASE/product/version
 
ORACLE_BASE是oracle的根目录,ORACLE_HOME是oracle产品的目录。
 简单说,你如果装了2个版本的oracle,那么ORACLE_BASE可以是一个,但ORACLE_HOME是2个
 
全局数据库名用于区别分布式数据库各个不同机器上的实例。
 SID用于区别同一台机器上的不同实例,
 即一个用于外部区分。
 一个用于内部区分。
 
$source .bash_profile
