创建Pacemaker集群
主要配置参数
- 集群的Pacemaker的使用的是：SBD设备
- 本次配置涉及两台虚拟机，分别是：ascs01，ascs02。
- ASCS负载均衡器的前端地址为：vascs01 (10.0.0.30)，探针端口为：62000。
- ERS负载均衡器的前端地址为：vers01 (10.0.0.39)，探针端口为：62102。
注意：和官方文档保持一致，操作步骤前缀分别代表：
- [A] – 两台机器都需要执行
- [1] – 只需在结点1上执行
- [2] – 只需在结点2上执行
设置SBD设备
目标机器ascs01和ascs02。
[A] 连接到 iSCSI 设备
启用iSCSI 和 SBD 设备：
ascs01:~ # sudo systemctl enable iscsid Created symlink from /etc/systemd/system/multi-user.target.wants/iscsid.service to /usr/lib/systemd/system/iscsid.service.
ascs01:~ # sudo systemctl enable iscsi
Created symlink from /etc/systemd/system/corosync.service.requires/sbd.service to /usr/lib/systemd/system/sbd.service.
[1] 在第一个节点上更改发起程序名称
ascs01:~ # sudo vi /etc/iscsi/initiatorname.iscsi
更改InitiatorName的值为：
InitiatorName=iqn.2006-04.ascs01.local:ascs01
[2] 在第二个节点上更改发起程序名称
ascs02:~ # sudo vi /etc/iscsi/initiatorname.iscsi
更改InitiatorName的值为：
InitiatorName=InitiatorName=iqn.2006-04.ascs02.local:ascs02
[A] 重新启动 iSCSI 服务
重启iSCSI 服务加载配置
ascs01:~ # sudo systemctl restart iscsid
ascs01:~ # sudo systemctl restart iscsi
连接iSCSI设备。10.0.0.51是目标服务器的地址；端口为：3260；ASCS集群对应SBD设备名称为：iqn.2006-04.vascs01.local:vascs01。
ascs01:~ # sudo iscsiadm -m discovery --type=st --portal=10.0.0.51:3260 10.0.0.51:3260,1 iqn.2006-04.vnfs01.local:vnfs01 10.0.0.51:3260,1 iqn.2006-04.vascs01.local:vascs01 10.0.0.51:3260,1 iqn.2006-04.vhana01.local:vhana01
ascs01:~ # sudo iscsiadm -m node -T iqn.2006-04.vascs01.local:vascs01 --login --portal=10.0.0.51:3260 Logging in to [iface: default, target: iqn.2006-04.vascs01.local:vascs01, portal: 10.0.0.51,3260] (multiple) Login to [iface: default, target: iqn.2006-04.vascs01.local:vascs01, portal: 10.0.0.51,3260] successful.
ascs01:~ # sudo iscsiadm -m node -p 10.0.0.51:3260 --op=update --name=node.startup --value=automatic
确保iSCSI 设备可用，并标注对应的设备名称，后面步骤会用到：
ascs01:~ # lsscsi | grep vascs01 [6:0:0:0] disk LIO-ORG vascs01 4.0 /dev/sdc
现在根据设备名称获取设备ID
ascs01:~ # ls -l /dev/disk/by-id/scsi-* | grep .*3600.*sdc lrwxrwxrwx 1 root root 9 May 2 05:40 /dev/disk/by-id/scsi-3600140526c37c29bd7845a59c0ba9f62 -> ../../sdc
以 scsi-3开头的设备就是我们的目标设备ID：/dev/disk/by-id/scsi-3600140526c37c29bd7845a59c0ba9f62
[1] 创建 SBD 设备
ascs01:~ # sudo sbd -d /dev/disk/by-id/scsi-3600140526c37c29bd7845a59c0ba9f62 -1 10 -4 20 create Initializing device /dev/disk/by-id/scsi-3600140526c37c29bd7845a59c0ba9f62 Creating version 2.1 header on device 4 (uuid: b65c9786-ecb9-42a4-a499-26aba4df93e9) Initializing 255 slots on device 4 Device /dev/disk/by-id/scsi-3600140526c37c29bd7845a59c0ba9f62 is initialized.
[A] 适配 SBD 配置
打开SBD配置文件：
ascs01:~ # sudo vi /etc/sysconfig/sbd
填写SBD_DEVICE的值，并确保SBD_PACEMAKER=yes，SBD_STARTMODE=always，形如：
SBD_DEVICE="/dev/disk/by-id/scsi-3600140526c37c29bd7845a59c0ba9f62" SBD_PACEMAKER=yes SBD_STARTMODE=always
更新softdog 配置文件

[1] 启用 SSH 访问
复制ascs02的公钥至ascs01授权密钥文件：
ascs01:~ # sudo vi /root/.ssh/authorized_keys
[A] 安装 HA 扩展
nfs01:~ # sudo zypper install sle-ha-release fence-agents
[A] 设置主机名称解析
忽略，因为已配置DNS服务器。
[1] 安装群集
ascs01:~ # sudo ha-cluster-init ! NTP is not configured to start at system boot. Do you want to continue anyway (y/n)? y /root/.ssh/id_rsa already exists - overwrite (y/n)? n Network address to bind to (e.g.: 192.168.1.0) [10.0.0.0][回车] Multicast address (e.g.: 239.x.x.x) [239.38.88.171][回车] Multicast port [5405] SBD is already configured to use /dev/disk/by-id/scsi-36001405cb3ac7b3fb5547f8a2a3882b6 - overwrite (y/n)? n Hawk cluster interface is now running.

[A] 重置hacluster密码
ascs01:~ # sudo passwd hacluster New password: Retype new password: passwd: password updated successfully
[A] 配置corosync 结点列表
编辑corosync配置文件：
nfs01:~ # sudo vi /etc/corosync/corosync.conf
更新transport，nodelist，expected_votes，two_node的值，

重启corosync 服务
ascs01:~ # sudo service corosync restart
[1] 修改pacemaker的默认设置
ascs01:~ # sudo crm configure rsc_defaults resource-stickiness="1"
SAP NetWeaver ASCS/ERS 安装准备
安装SUSE连接器
ascs01:~ # sudo zypper install sap_suse_cluster_connector
更新SAP资源代理
资源包已安装，无需再更新
ascs01:~ # sudo grep 'parameter name="IS_ERS"' /usr/lib/ocf/resource.d/heartbeat/SAPInstance <parameter name="IS_ERS" unique="0" required="0">
设置域名解析
已配置DNS服务器，无须host记录。
创建共享目录
ascs01:~ # sudo mkdir -p /sapmnt/NW1 ascs01:~ # sudo mkdir -p /usr/sap/trans ascs01:~ # sudo mkdir -p /usr/sap/NW1/SYS ascs01:~ # sudo mkdir -p /usr/sap/NW1/ASCS00 ascs01:~ # sudo mkdir -p /usr/sap/NW1/ERS02

配置autofs自动挂载
在/etc/auto.master中追加一行自动加载配置记录。
ascs01:~ # sudo vi /etc/auto.master
追加内容为：
/- /etc/auto.direct
创建一个auto.direct配置文件：
ascs01:~ # sudo vi /etc/auto.direct
增加ASCS和ERS安装所依赖的共享目录挂载信息：
/sapmnt/NW1 -nfsvers=4,nosymlink,sync vnfs01.azure-sap.poc:/NW1/sapmntsid /usr/sap/trans -nfsvers=4,nosymlink,sync vnfs01.azure-sap.poc:/NW1/trans /usr/sap/NW1/SYS -nfsvers=4,nosymlink,sync vnfs01.azure-sap.poc:/NW1/sidsys /usr/sap/NW1/ASCS00 -nfsvers=4,nosymlink,sync vnfs01.azure-sap.poc:/NW1/ASCS /usr/sap/NW1/ERS02 -nfsvers=4,nosymlink,sync vnfs01.azure-sap.poc:/NW1/ASCSERS
重启autofs挂载共享目录：
ascs01:~ # sudo systemctl enable autofs Created symlink from /etc/systemd/system/multi-user.target.wants/autofs.service to /usr/lib/systemd/system/autofs.service. ascs01:~ # sudo service autofs restart
此时可以通过mount命令检查一下，刚才挂载的几个目录是否处于活动状态：
ascs01:~ # mount | grep NW1 /etc/auto.direct on /usr/sap/NW1/ERS02 type autofs (rw,relatime,fd=7,pgrp=49534,timeout=600,minproto=5,maxproto=5,direct) /etc/auto.direct on /usr/sap/NW1/SYS type autofs (rw,relatime,fd=7,pgrp=49534,timeout=600,minproto=5,maxproto=5,direct) /etc/auto.direct on /sapmnt/NW1 type autofs (rw,relatime,fd=7,pgrp=49534,timeout=600,minproto=5,maxproto=5,direct) /etc/auto.direct on /usr/sap/NW1/ASCS00 type autofs (rw,relatime,fd=7,pgrp=49534,timeout=600,minproto=5,maxproto=5,direct)
Configure SWAP 文件
编辑waagent.conf
ascs01:~ # sudo vi /etc/waagent.conf
设置ResourceDisk.EnableSwap=y，ResourceDisk.SwapSizeMB=2000
# Create and use swapfile on resource disk. ResourceDisk.EnableSwap=y # Size of the swapfile. ResourceDisk.SwapSizeMB=2000
重启代理服务：
ascs01:~ # sudo service waagent restart
安装 SAP NetWeaver ASCS/ERS
ASCS的安装机器在ascs01上；
[1] 为 ASCS 实例创建虚拟 IP 资源和运行状况探针
sudo crm node standby ascs02

[1] 调整 ASCS/SCS 和 ERS 实例配置文件
ASCS/SCS 配置文件
编辑ASCS的配置文件：
ascs01:~ # vi /sapmnt/NW1/profile/NW1_ASCS00_vascs01
把EN参数对应的命令：把Restart_Program的值改为start：
#Restart_Program_01 = local $(_EN) pf=$(_PF)Start_Program_01 = local $(_EN) pf=$(_PF)
文件末尾追加：
# Add the following lines service/halib = $(DIR_CT_RUN)/saphascriptco.so service/halib_cluster_connector = /usr/bin/sap_suse_cluster_connector # Add the keep alive parameter enque/encni/set_so_keepalive = true
ERS 配置文件
编辑ERS配置文件：
ascs01:~ # vi /sapmnt/NW1/profile/NW1_ERS02_vers01
文件末尾追加：
# Add the following lines service/halib = $(DIR_CT_RUN)/saphascriptco.so service/halib_cluster_connector = /usr/bin/sap_suse_cluster_connector
[A] 配置 Keep Alive
ascs01:~ # sudo sysctl net.ipv4.tcp_keepalive_time=120 net.ipv4.tcp_keepalive_time = 120
[A] 在安装后配置 SAP 用户
ascs01:~ # sudo usermod -aG haclient nw1adm
[1] 将 ASCS 和 ERS SAP 服务添加到 sapservice 文件
ascs01:~ # cat /usr/sap/sapservices | grep ASCS00 | sudo ssh ascs02 "cat >>/usr/sap/sapservices"
ascs01:~ # sudo ssh ascs02 "cat /usr/sap/sapservices" | grep ERS02 | sudo tee -a /usr/sap/sapservices

创建STONITH设备
如何创建自定义角色，服务主体，分配角色，可参考《创建STONITH设备》
sudo crm configure property stonith-timeout=900
sudo crm configure primitive rsc_st_azure stonith:fence_azure_arm \ params subscriptionId="订阅Id" resourceGroup="资源组名称" tenantId="租户Id" login="APPID" passwd="秘钥"
sudo crm configure fencing_topology \ stonith-sbd rsc_st_azure
sudo crm configure property stonith-enabled=true
配置结束以后，机器中资源的状态，如下图：
故障转移测试
接下来，我们会通过调整ASCS01和ASCS02两台机器的开关机状态，然后在客户端jump01上通过PowerShell测试ASCS和ERS的端口打开情况，简单验证集群的故障转移结果。
在此之前现在PowerShell控制定义个检测函数：
function ASCS-ERS-Cluster-Test
{
$ascs = Test-NetConnection vascs01.azure-sap.poc -Port 50013 -InformationLevel Quiet;
"ASCS:$ascs"
$ers = Test-NetConnection vers01.azure-sap.poc -Port 50213 -InformationLevel Quiet;
"ERS:$ers"
}
第一步：保证两台机器ASCS01和ASCS02都开机：
如下图，ascs资源工作在ascs02上，ers工作在ascs01上：
jump01上端口检测如下，测试通过。
