在linux平台下面安装oracle，要做好多的准备工作。比如建立user，，修改环境变量，一些oracle所需的参数。现在整理成shell脚本，以方便安装。
一、创建安装脚本
vi install.sh
#/bin/bash
. ./adduser.sh
. ./sysctl.sh
. ./limits.sh
. ./mkdir.sh
. ./chprofile.sh
二、添加用户及用户组
vi adduser.sh
#/bin/bash
addgroups=oinstall dba
addusers=oracle
for group in $addgroups ; do
if [ -z $( awk -f: '{print $1}' /etc/group |grep $group) ]; then
groupadd $group
echo add new group $group
else
echo group $group already existed
fi
done
for user in $addusers ; do
if [ -z $( awk -f: '{print $1}' /etc/passwd |grep $user) ]; then
useradd $user
echo add new user $user
else
echo user $user already existed
fi
done
if $(usermod -g oinstall -g dba oracle) ; then
echo modify user oracle account success
else
echo modify user oracle account failure
fi
三、创建所需的目录
vi mkdir.sh
#/bin/bash
oracle_file_base=/u01/app/oracle
oracle_file_var=/var/opt/oracle
oracle_file_home=$oracle_file_base/product/10.2.0/db_1
for directory in $oracle_file_base $oracle_file_var $oracle_file_home ; do
if [ -d $directory ]; then
echo directory $directory already existed
else
mkdir -p $directory
chown -r oracle.dba $directory
echo change directory $directory owner and group success
fi
done
