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。
