标题: 手把手教你使用Newstart HA（二）

三、配置NewStart HA

整个配置过程分两步，集群初始化和服务初始化，必须按以上顺序进行操作。HA支持命令行（cli）及web两种管理工具进行配置，下面是cli工具的配置过程。

配置之前确认以下信息：

1.两台服务器的主机名称；

2.心跳和工作链路的网卡名对应并且相同，并配置好所有网卡的固定IP；

3.确定访问oracle/tomcat的浮动IP；

4.HA脚本位置；（/home/script/oracle.ps和tomcat.ps）

5.清楚磁阵挂载目录；（安装oracle时已建好,这里为/home/db）

6. 第三方IP列表：可选，建议配置3～5个IP，这些IP与工作网卡属于相同网段，注意不要配成两台服务器的IP，其作为是检测自身网络正常与否。

集群初始化，格式：cluster-init

命令行下运行cli指令，进入cli管理工具，然后运行cluster-init。在开始之前再啰嗦一下，接下来的整个集群配置过程中，粗体表示根据实际环境填写的值，斜粗体表示说明（其中回车表示推荐配置）。

cli:~>cluster-init

======================================

Cluster Initialization Utility

======================================

This utility sets up the initialization information of a 2-node cluster.

It prompts you for the following information:

- Hostname

- Information about the heartbeat channels

- How long between heartbeat

- How long to declare heartbeat fails

- Watchdog configuration

- Lock disk configuration

Please input cluster name:cluster_ora 自定义集群名称

Input the first node name and IP:suse11-1 192.168.1.92

Input the second node name and IP:suse11-2 192.168.1.93

How long between heartbeats(in seconds)[1]:直接回车

How long to declare heartbeat has broken(in seconds)[60]:直接回车

Do you want to enable watchdog device ? (yes/no)[no]:直接回车

Please choose multicast heartbeat channel:

0) eth0

1) bond0

Select a multicast heartbeat channel [0, 1]:0

Another multicast heartbeat channel? (yes/no)[yes]:no

Do you want to add a serial heartbeat channel? (yes/no)[yes]:直接回车

Input serial heartbeat channel[/dev/ttyS0]:直接回车

Another serial heartbeat channel? (yes/no)[yes]:no

Do you want to enable worklink_hb ? (yes/no)[yes]:直接回车

Please run service-init to initialize you services.

集群初始化完成,接下来进行服务初始化。

服务初始化，格式：service-init

这里配置两个服务，先配数据库oracle,然后配置tomcat。cli管理工具中运行service-init，进行服务初始化。

cli:~>service-init

Please run cluster-start to start the HA system,

or run cluster-restart to restart the HA system.

服务初始化完成，此时集群不要启动，保持原状态，具体原因接下来说到。

HA脚本检测

前面已编写完oracle及tomcat脚本，但实际环境中仍需验证现有脚本能否完全管控应用，为此，HA提供了check-script工具作为快捷验证方法。注意操作前确认集群是停止状态，查看方式:cluster-stat。

cli:~>cluster-stat

The HA system is not running now.

cli:~>check-script

Current service:

0) name: oracle

1) name: tomcat

2) cancel

Select a(n) service [0, 2]:0

Current Application:

0) script: /home/script/oracle.ps

1) cancel

Select a(n) Application [0, 1]:0

Begin to test resource script......

Start resource oracle.ps: pass

Check resource oracle.ps when running: pass

Start resource oracle.ps when running: pass

Check resource oracle.ps when running: pass

Stop resource oracle.ps when running: pass

Check resource oracle.ps when stopped: pass

Stop resource oracle.ps when stopped: pass

Check resource oracle.ps when stopped: pass

Start resource oracle.ps: pass

Forcedstop resource oracle.ps when running: pass

Check resource oracle.ps when stopped: pass

Forcedstop resource oracle.ps when stopped: pass

Check resource oracle.ps when stopped: pass

End to test resource

Oracle脚本检测通过，全pass,没问题

cli:~>check-script

Current service:

0) name: oracle

1) name: tomcat

2) cancel

Select a(n) service [0, 2]:1

Current Application:

0) script: /home/script/tomcat.ps

1) cancel

Select a(n) Application [0, 1]:0

Begin to test resource script......

Start resource tomcat.ps: pass

Check resource tomcat.ps when running: pass

Start resource tomcat.ps when running: pass

Check resource tomcat.ps when running: pass

Stop resource tomcat.ps when running: pass

Check resource tomcat.ps when stopped: pass

Stop resource tomcat.ps when stopped: pass

Check resource tomcat.ps when stopped: pass

Start resource tomcat.ps: pass

Forcedstop resource tomcat.ps when running: pass

Check resource tomcat.ps when stopped: pass

Forcedstop resource tomcat.ps when stopped: pass

Check resource tomcat.ps when stopped: pass

End to test resource

tomcat脚本检测通过，全pass,没问题

四、集群启动及状态查询

1、启动集群：进入cli,启动集群，指令：cluster-start

cli:~>cluster-start

[suse11-1]Starting High-Availability services:

Configuration file checked ok.

..done

Configuration file checked ok.

[suse11-2]Starting High-Availability services:

..done

2、集群状态查询：集群状态包括节点、心跳链路，工作链路和服务状态。进入cli,输入指令：cluster-stat（动态周期性刷新）查看。

cli:~>cluster-stat

Press Ctrl-C or 'Q' to exit

Date: Fri Apr 26 09:45:13 2013

Member status

suse11-1 UP

suse11-2 UP

WorkLink suse11-1 suse11-2

bond0 ONLINE ONLINE

HeartbeatLink suse11-1 suse11-2 status

network eth0 eth0 ONLINE

serial /dev/ttyS0 /dev/ttyS0 ONLINE

LockDisk /dev/sdb1 /dev/sdb1 ONLINE

ServiceName suse11-1 suse11-2 Enable

*oracle running stopped YES

tomcat stoped running YES

状态图说明：节点(Member)状态都是”UP”(正常)，工作链路（WorkLink）bond0都是”ONLINE”(正常)，心跳链路(HeartbeatLink)都是”ONLINE(正常)，服务oracle现运行（running）在suse11-1上, 服务tomcat现运行（running）在suse11- 2节点。
