1.配置系统环境

1.1配置本地yum源

--挂载cd
mount /dev/cdrom /mnt && mount -a

--备份原有yum文件
mv /etc/yum.repos.d/public-yum-ol6.repo /etc/yum.repos.d/public-yum-ol6.repo.bak

--新建yum文件
cat >> /etc/yum.repos.d/yum.repo <<EOF
[Oracle] 
name=Oracle 11g
baseurl=file:///mnt
gpgcheck=0
enabled=1
EOF

--刷新重载yum
yum clean all && yum makecache

1.2关闭防火墙

--永久关闭防火墙
service iptables stop && chkconfig iptables off

--修改selinux内核配置
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

1.4修改主机名添加host解析

节点一：orcl1

orcl1修改主机名
sed -i 's/HOSTNAME=enforcing/HOSTNAME=rac1/g' /etc/sysconfig/network

节点二：orcl2

orcl2修改主机名
sed -i 's/HOSTNAME=enforcing/HOSTNAME=rac2/g' /etc/sysconfig/network

--配置hosts解析
cat >> /etc/hosts << EOF
#public ip
192.168.100.218 rac1
192.168.100.219 rac2
#private ip
192.168.10.20 rac1pri
192.168.10.21 rac2pri
#vip
192.168.100.220 rac1vip
192.168.100.221 rac2vip
#sanip
192.168.100.222 orclrac
EOF

1.5修改资源限制参数

--禁止路由生成自动ip
echo "NOZEROCONF=yes" >> /etc/sysconfig/network

--关闭透明大页
cat >>/etc/rc.d/rc.local <<EOF
if test -f /sys/kernel/mm/transparent_hugepage/enabled; then
echo never > /sys/kernel/mm/transparent_hugepage/enabled
fi
if test -f /sys/kernel/mm/transparent_hugepage/defrag; then
echo never > /sys/kernel/mm/transparent_hugepage/defrag
fi
EOF

--修改用户资源限制
cat >> /etc/security/limits.conf << EOF
