1 配置yum源
vim /etc/yum.repos.d/rhel-debuginfo.repo
ORADB1:
[Server]
name=Server
baseurl=file:///mnt/Server
enabled=1
gpgcheck=0
ORADB2:
[Server]
name=Server
baseurl=ftp://oradb1/pub/Server
enabled=1
gpgcheck=0
2 同时检查以下包是否被安装
rpm -q --queryformat "%{NAME}-%{VERSION}-%{RELEASE} (%{ARCH})\n" \
binutils \
compat-libstdc++-33 \
elfutils-libelf \
elfutils-libelf-devel \
gcc \
gcc-c++ \
glibc \
glibc-common \
glibc-devel \
glibc-headers \
ksh \
libaio \
libaio-devel \
libgcc \
libstdc++ \
libstdc++-devel \
make \
sysstat \
unixODBC \
unixODBC-devel
通过检查发现我的系统一下4个包没有安装：
package libaio-devel is not installed
package sysstat is not installed
package unixODBC is not installed
package unixODBC-devel is not installed
package sysstat is not installed
--挂载CD镜像到mnt目录下：
[root@localhost tmp]# mount /dev/cdrom /mnt/
mount: block device /dev/cdrom is write-protected, mounting read-only
--yum 安装这几个包
[root@localhost tmp]# yum install libaio-devel package libaio-devel unixODBC unixODBC-devel sysstat –y
--yum 安装第二个节点的时候可以重新挂载
[root@localhost tmp]# mount /dev/cdrom /var/ftp/pub/
mount: block device /dev/cdrom is write-protected, mounting read-only
3.关掉大部分不用服务(可能因人因环境而异).
chkconfig bluetooth --level 2345 off
chkconfig ip6tables --level 2345 off
chkconfig portmap --level 2345 off
chkconfig sendmail --level 2345 off
chkconfig vsftpd --level 2345 off
chkconfig iptables off
chkconfig ntpd off
4 在每一个节点上配置/etc/hosts文件，文件内容如下
# Public Network (eth0)
10.0.18.12 oradb1.bdstar.com oradb1
10.0.18.13 oradb2.bdstar.com oradb2
# Public Virtual IP (VIP) addresses (eth0:1)
10.0.18.120 oradb1-vip.bdstar.com oradb1-vip
10.0.18.130 oradb2-vip.bdstar.com oradb2-vip
# Private Interconnect (eth1)
10.10.10.120 oradb1-priv.bdstar.com oradb1-priv
10.10.10.130 oradb2-priv.bdstar.com oradb2-priv
#Compute node Client Access SCAN Interface details
10.0.18.36 oradb-scan.bdstar.com oradb-scan
5 修改主机名
[root@localhost ~]# vim /etc/sysconfig/network
Oradb1上添加如下：
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=oradb1.bdstar.com
Oradb2上添加如下：
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=oradb1.bdstar.com
6 配置集群时间同步服务 — (CTSS)
--不采用系统上的NTP服务，利用oracle集群的CTSS服务
[root@racnode1 ~]# /sbin/service ntpd stop
[root@racnode1 ~]# chkconfig ntpd off
[root@racnode1 ~]# mv /etc/ntp.conf /etc/ntp.conf.original
还要删除以下文件：
[root@racnode1 ~]# rm /var/run/ntpd.pid
7 内核参数的配置
[root@rac1 ~]# cd /etc/
[root@rac1 etc]# sysctl -p
net.ipv4.ip_forward = 0
net.ipv4.conf.defau
