第一章HACMP配置前硬件打算

在安装HA软件之前，首先连接好系统硬件设备，包括心跳线连接,

存储设备连接等。并将须要加到资源组中的卷组在分别导入到群集中的每

个节点上。

第二章HACMP软件安装

2.1操作系统补丁与指定包的安装

AIX系统须要如下软件包，并且AIX补丁版本达到最新。

bos.data

rsct.basic

(rsct.basic,hacmp,rsct.basic,rte,rsct.basic,sp)

(rsctpat.basic,hacmp,rsctpat.basic,rte,

rsctpat.basic,sp)

c,

rsctpat.clients,sp)

perfagent,tools

假如您要安装并行的资源组，还要安装下面的包:

2.2安装HACMP软件包

将HACMP5.3光盘加载到SERVER,由SMITTY进行安装。建议安装全部

HACMP5.3软件包，可担心装的包为haview,netwiew(Tivoli)0

2.3升级HACMP的补丁到最新

目前对HACMP5.3须要更新的补丁为：

IY94307,IY84883,IY79740,IY78404,

现在hacmp最新的补丁可以从IBM网站查询并下载,下载地址为：

2.4重启系统

安装如上软件包后，须要重启操作系统U

第三章HACMP的配置

3.1主备模式下HACMP配置

在主备模式下运行的两台主机(HOSTLHOST2)在正常状况下HOST1运

行应用系统，11OST2做为HOST1的备份服务器,当HOST1出现故障时,

HOST1上面的应用程序，对外服务IP地址，共享存储等资源将切换到H0ST2

服务器上面，接着对外供应服务。当II0ST1故障修复并重新启动上面HA服

务后，可以依据业务需求来选择是否让当前运行在H0ST2上面的资源自动

切换回到H0ST1服务器上面。

下面是两台主机(H03T1,H0ST2)在主备模式下的HACMP配置过程。

IP地址规划

群集中的两个节点(hostl,host2)上面的IP地址规划如下，修改每个

节点上面/ctc/hosts文件，添加如下内容：

0.1hostl_bootlhostl

0.1hostl_boot2hostl

10.21.50.1hostl_prehostl

10.21.50.10hostl_srvhost2

0.2host2_bootlhost2

192.168.20.2host2_boot2host2

10.21.50.2host2_prehost2

修改每个节点上面/usr/cs/sbin/cluster/etc/rhost文件，添加如下

内容

hostlboot1

hostlboot2

hostlpre

hostlsrv

host2_bootl

host2boot2

host2_pre

设置BOOT地址

为群集中的每个节点设置Boot地址，设置后，要求各个节点之间的

boot地址可以相互ping通。设置后，每个节点上面的网络设置信息如下:

.3串口通信测试

在群集中的两个节点中,hosll的llyO和hosl2的ttyO组成一个串行

网络，对该网络进行通信测试，以验证串行网络的通信是否正常。

host2#cat</dev/ttyO

hostl#cat/etc/hosts>/dev/ttyO

假如在hostl上面通过串口传递一个消息后，在host2上面可以接收

到所发送的信息，说明串口通信正常。

创建Cluster并添加HA节点

在hostl上面对HA进行配置，配置后将配置唁息同步到host2主机

既可。
