5.配置Oracle网络

I.硬件配置要求 ? 每个服务器节点至少需要2块网卡，一块对外网络接口，一块私有网络接口（心跳）。 ? 如果你通过OUI安装Oracle集群软件，需要保证每个节点用于外网或私网接口（网卡名）保证一致。比如，node1使用eth0作为对外接口，node2就不能使用eth1作为对外接口。

II.IP配置要求

?

存在为集群服务的DHCP

? ?

DHCP能为每个节点提供足够的IP，一个虚拟IP、3个SCAN IP

?

III.非GNS下手动配置IP实例

6.检查操作系统软件包

首先，根据操作系统版本到官方文档中找到安装包需求列表，如下图

可以通过mount安装盘或直接通过yum源检查和安装所需要的包：

点击(此处)折叠或打开

1. 2. 3. 4. 5.

# rpm -qa packages_name # rpm -ivh packages_name

# yum list packages_name # yum install packages_name

这里还要提一下：CVUdisk这个包也可以在这个时候一起安装好，以备之后使用CVU时会用到。

点击(此处)折叠或打开

1. 2. 3. 4. 5. 6. 7.

# 检查是否已经安装 # rpm -qi cvuqdisk

# 如果已安装需要先卸载之前的版本 # rpm -e cvuqdisk # 安装新版本

# CVUQDISK_GRP=oinstall; export CVUQDISK_GRP # rpm -ivh cvuqdisk-1.0.9-1.rpm

7.关闭NTP及端口范围参数修改

点击(此处)折叠或打开

1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16.

# Oracle建议使用Oracle Cluster Time Synchronization Service，因此关闭删除NTP # /sbin/service ntpd stop # chkconfig ntpd off

# rm /etc/ntp.conf (mv /etc/ntp.conf /etc/ntp.conf.old) # rm /var/run/ntpd.pid

检查TCP/UDP端口范围

# cat /proc/sys/net/ipv4/ip_local_port_range 如果已经显示9000 65500,就不用进行下面的步骤了

# echo 9000 65500 > /proc/sys/net/ipv4/ip_local_port_range # vim /etc/sysctl.conf # 添加此行：

# TCP/UDP port range

net.ipv4.ip_local_port_range = 9000 65500 # 重启网络

# /etc/rc.d/init.d/network restart

8.调整.bash_profile内容并设置显示地址

点击(此处)折叠或打开

1.

2. 3. 4. 5. 6. 7. 8. 9.

设置参数： $ su - root

# mkdir /mount_point/tmp # chmod 775 /mount_point/tmp # exit

$ vi .bash_profile 加入行：

TEMP=/mount_point/tmp
