• 第一步：一键准备环境脚本

centos 6上安装oracle 10g安装

环境准备：

• 网卡配置固定ip
• /etc/hosts里配置好主机名与ip的解析
• 防火墙和selinux关闭

第一步：一键准备环境脚本

脚本可以多次运行，主机名是oracle可以进行更改，有设置aliyun的epel源和yum源，内容如下：

#!/bin/bash
# create a auto-install oracle_10g-db
# Author: clc
# create data: 2017-04-28
# OS: CENTOS 6
# set hostname is oracle

function env_prepare(){
# stop iptables and selinux
/etc/init.d/iptables stop && chkconfig --level 35 iptables off
setenforce 0 && sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/selinux/config 

#change hostname
hostname oracle
a=`grep -c  "HOSTNAME=oracle" /etc/sysconfig/network`
if [ $a -lt 1 ]
    then
		echo "HOSTNAME=oracle">>/etc/sysconfig/network
fi

#add hostname to hosts
a_ip=`ifconfig |awk -F "[: ]+" '{if(NR==2)print $4}'`
a_host=`hostname`
bb=`grep -c "${a_host}" /etc/hosts`
if [ $bb -lt 1 ]
	then
	echo "${a_ip}  ${a_host}" >>/etc/hosts
fi


#change repo and epel yum
ee=`ls /etc/yum.repos.d/|grep epel.repo|wc -l`
if [ $ee -lt 1 ]
	then
	mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup\
	&& wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo\
	&& wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo

安装过程中会跳出一个错，可以忽略，
最后配置开机启动，dbstart启动的时候会报错，因为dbstart文件中监听位置配置错了，配置成以下：

#ORACLE_HOME_LISTNER=/ade/vikrkuma_new/oracle #这个是原来的配置，这里位置错了，导致启动不了。
ORACLE_HOME_LISTNER=$ORACLE_HOME

# vi /etc/oratab   --修改开机启动，将值由N设为Y
hyl:/home/u01/app/oracle/product/10.2.0/db_1:Y

开机启动配置：/etc/rc.local

su - oracle -c "/data/oracle/product/10.2.0/db_1/bin/lsnrctl start"
su - oracle -c "/data/oracle/product/10.2.0/db_1/bin/dbstart "
su - oracle -c "isqlplusctl start"
su - oracle -c "emctl start dbconsole"
