SUSEHA配置手冊

1、SUSE HA配置手冊1. SUSE HA軟件包安裝兩個節(jié)點均使用 yast2安裝suse HA軟件包（需要額外 HA CD與SUSE 11SP啲系統(tǒng)ISO。2. 初始化配置集群執(zhí)行yast2 cluster初始化配置集群拷貝配置文件到節(jié)點2scp -rp /etc/coros ync/ sapprdap2:/etc/coros ync/節(jié)點2執(zhí)行Chkc onfig ope nais onrcope nais on兩個節(jié)點執(zhí)行 passwd hacluster3. 配置SDB/etc/sysconfig/kernel中增加紅框中的行使用sbd命令創(chuàng)建sbd盤創(chuàng)建sbd文件4. 配置HA資源執(zhí)

2、行 crm_gui創(chuàng)建克隆資源組，SBD與PING。具體配置如下圖：雙擊配置之前創(chuàng)建好的 sbd盤指向網(wǎng)關(guān)創(chuàng)建資源組saprg并按順序配置各種 SAP資源各資源的詳細屬性如下：需要提前在兩個節(jié)點創(chuàng)建/etc/nfsexport目錄nfs_ip指向虛擬主機名SAP腳本是lsb類型，腳本需要提前放在/etc/下，名字就叫sapecp. 腳本詳細內(nèi)容為：sapprdap1: # cat /etc/sapecp#!/bin/sh# BEGIN INIT INFO# Provides:# Required-Start:$local_fs $network# Required-Stop:$local_fs
