linux上安装Oracle 11g R2 标准版 64位
一.Oracle 安装前的准备
检查一下包，必须全部安装：

二.创建oracle用户和组
su - root
groupadd oinstall
groupadd dba
useradd -g oinstall -G dba oracle
echo oracle|passwd --stdin oracle
三.系统参数和配置文件
1.添加如下到文件/etc/sysctl.conf
kernel.sysrq = 0
kernel.core_uses_pid = 1
net.ipv4.tcp_syncookies = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.shmmax = 4294967295
kernel.shmall = 268435456
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
fs.file-max = 6815744
fs.aio-max-nr = 1048576
/sbin/sysctl -p
2.添加如下到文件/etc/security/limits.conf
session required /lib64/security/pam_limits.so
session required pam_limits.so
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
3.添加如下到文件/etc/profile
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
四.修改环境变量
/home/oracle/.bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
export ORACLE_SID=orcl
export ORACLE_BASE=/home/oracle/
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:ORACLE_HOME/lib
export ORACLE_HOME=/home/oracle/product/11.2.0/dbhome_1
export ORACLE_HOME_LISTNER=$ORACLE_HOME
PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin
umask 022
export PATH
sh /home/oracle/.bash_profile
五.开始安装
进入到oracle的instal文件夹下
./runlnstaller
如果不出意外，会出现oracle的安装图形化界面，
按照提示一步一步安装即可
在安装第二步会oracle会检测环境是否符合，如果提示swap或大，或小，忽略，下一步
完成之后，按照提示用root执行
root.sh和
orainstRoot.sh
回车即可
到此基本就完成了。
六.创建实例
通过图形化来创建实例
cd $home_ORACLE/product/11.2.0/dbhome_1/bin/
./dbca
然后会出现创建实例的图形化界面，按照提示进行下一步就可以了。
