SUSE HA软件包安装两个节点均使用yast2安装suse HA软件包需要额外HA CD与SUSE 11SP3的系统ISO。2. 初始化配置集群执行yast2 cluster初始化配置集群拷贝配置文件到节点2scp -rp /etc/corosync/corosync.confsapprdap2:/etc/corosync/节点2执行Chkconfigopenais on rcopenais on两个节点执行passwdhacluster3. 配置SDB/etc/sysconfig/kernel中增加红框中的行使用sbd命令创立sbd盘创立sbd文件4. 配
2、置HA资源执行crm_gui创立克隆资源组，SBD与PING。具体配置如下列图：双击配置之前创立好的sbd盘指向网关创立资源组saprg并按顺序配置各种SAP资源各资源的详细属性如下：需要提前在两个节点创立/etc/nfsexport目录nfs_ip指向虚拟主机名SAP脚本是lsb类型，脚本需要提前放在/etc/init.d下，名字就叫sapecp.脚本详细内容为：sapprdap1: # cat /etc/init.d/sapecp#!/bin/sh# BEGIN INIT INFO# Provides: sapbip.sh# Required-Start: $local_fs $netwo
