wordSUSE HA配置手册1. 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.conf sapprdap2:/etc/corosync/节点2执行Chkconfig openais on rcopenais on两个节点执行passwd hacluster3. 配置SDB/etc/sysconfig/kernel中增加红框中的行使用sbd命令创建sbd盘创建sbd文件4. 配置HA资源执行crm_gui创建克隆资源组，SBD与PING。具体配置如如下图：双击配置之前创建好的sbd盘指向网关创建资源组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建/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.脚本详细容为：sapprdap1: # cat /etc/init.d/sapecp #!/bin/sh# BEGIN INIT INFO# Provides: sapbip.sh# Required-Start: $local_fs $network# Required-Stop: $local_fs# Default-Start: 2 3 4 5# Default-Stop: 0 1 6# Short-Description: sapbip.sh# Description: sapbip.sh pop & imap daemon# END INIT INFO# Run-level Startup script for the SAP instance# chkconfig: 345 91 19# description: Startup/Shutdown SAP instanceSAP_OWNR=ecpadmHOST_NAME=hostnameHOST1=sapprdap1HOST2=sapprdap2# depending on parameter - startup, shutdown, restart# of the instance and listener or usage displaycase $1 in start) # SAP instance startup echo mount nfss filesystem num=df -h |grep sapmnt|wc -l if $num = 1 then mount sapprdap:/export/sapmnt/ECP /sapmnt/ECP mount sapprdap:/export/usr/sap/trans /usr/sap/trans fi echo -n Starting SAP instance su - $SAP_OWNR -c startsap R3 ASCS01 sapecpap echo Start SAP ASCS01 ok. su - ecpadm -c startsap R3 echo start remote SAP Instance num2=ssh $HOST1 df -h |grep sapmnt|wc -l if $num2 != 2 then ssh $HOST1 sapprdap:/export/sapmnt/ECP /sapmnt/ECP ssh $HOST1 sapprdap:/export/usr/sap/trans /usr/sap/trans fi ssh $HOST2 su - $SAP_OWNR -c startsap R3 D00 echo Start D00 instance in sapprdap2 ok. ; stop) # SAP instance shutdown echo -n Shutdown SAP instance su - ecpadm -c stopsap R3 su - ecpadm -c stopsap R3 ASCS01 sapprdap su - $SAP_OWNR -c saposcol -k su - $SAP_OWNR -c cleanipc 00 remove su - $SAP_OWNR -c cleanipc 01 remove su - $SAP_OWNR -c cleanipc 10 remove su - ecpadm -c sapcontrol -nr 00 -function StopService su - ecpadm -c sapcontrol -nr 01 -function StopService su - ecpadm -c sapcontrol -nr 10 -function StopService kill -9 ps -ef|grep $SAP_OWNR|grep -v grep|awk print $2 echo Stop SAP instance ok. # umount -l /sapmnt/ECP ; restart) $0 stop $0 start ; reload) echo reload mand not supported. ; status) num=ps aux -cols=1024|grep ms.sapECP_ASCS01|grep -v grep|wc -l echo running process ms.sapECP_ASCS01 $num # $num -gt 0 | exit 1 # num=ps aux -cols=1024|grep en.sapECP_ASCS01|grep -v grep|wc -l # echo running process en.sapECP_ASCS01 $num # $num -gt 0 | exit 1 exit 0 ; *) echo Usage: $0 start|stop|restart|reload|status exit 1esacexit 0sapprdap1: #配置SAP启停超时为10分钟HA配置完成。5. SUSE HA常用命令1. 启停rcopenais startrcopenais stop2. 配置crm_gui3. 切换或者直接重启主机4. 监控crm_mon /
