Newstart HA 配置技巧NewStart HA是一款支持多种Linux平台的双机高可用软件,具有稳定可靠，简约易用等特性。

在很多电信级服务器中都有用。

本文主要介绍NewStart HA 的典型配置技巧。

Newstart HA提供命令行工具（cli）及web工具配置方式，下面就两种配置方式分别讲述。

为保证配置顺利进行，以下准备工作要提前做好：1.已安装主流linux操作系统（如suse 9/10/11,rehat5/6,cgslv3/v4等）；2.两个节点的主机名不能相同；3.两个节点的心跳链路和工作链路的网卡名都要求相同（如nodeA工作链路网卡名为eth0，则nodeB工作链路网卡名必须为eth0），心跳链路建议配2条或以上，工作链路建议做bonding，然后配置好各个网卡的物理IP；4.串口，HA提供串口线组建串口心跳链路，如机子不具备串口设备，可不配，但要保证总的心跳链路数量在两条或以上；5.确定业务的浮动IP地址值；6.共享存储，如使用该类设备，请分别创建好两个节点上的挂载目录；7.两节点已分别安装好业务应用；8.HA安装程序放置服务器上，如果是iso文件，使用二进制方式上传，如果是光盘，把安装光盘放到服务器CDROM中。

HA程序安装：以上准备工作完成后，就可以进行HA的安装，以iso安装文件为例，挂载安装程序到mnt目录，然后进行安装，如：# mount -o loop nsha-3.0.1.07.iso /mnt#/mnt/install安装过程很简单，需注意3个地方已使用粗体标出，粗斜体表示注解。

NewStart HA Installation ProgramVersion: 3.0.1.07Support email: ha-support@1)NewStart HA Server Program and CLI Administrative Tool12)Web-based Administrative Tool (options)(version: 20121101)23)All components34)Cancel说明：1为主程序和cli管理工具，2为web管理工具，3为以上全部组件select the components to be installed [1-4]?3…(过程省略)please enter the SN: 00TB24-FC0TCF-629A1H-B00D46 //试用SN号…(过程省略)Do you want to start web-based administrative tool automatically as a system service? y(es) or n(o)? y //系统启动时是否自动启动Web管理工具…(过程省略)The component(s) is installed completely.主程序及其组件已安装完成，接下来是license的申请，做完这一步HA的安装才算真正完成，操作如下：1、把两台机子上的/etc/ha.d/lic/newstartha.key文件打包（名字区分好，如newstartha.key_node1/2，二进制(bin)方式下载）,然后发送到邮箱：ha-support@进行license文件的申请。

2、收到的license文件后改名为newstartha.lic，用二进制(bin)方式上传到服务器，放到/etc/ha.d/lic/目录，因为每个节点newstartha.lic内容不同，key文件与license文件一一对应，所以不要搞混，否则HA无法启动。

至此，HA安装完成，接下来讲述集群配置方式。

一、命令行工具（cli）配置方式集群的配置主要分两块，分别是集群初始化和服务初始化，必须按以上顺序进行初始化；在开始之前，有几个概念先了解一下：1、仲裁盘：数据安全保障机制，需要在共享磁盘上划分一块小空间， 30M左右，不需格式化，作用是防止服务双挂。

（可选，但推荐配置）2、第三方IP列表：与工作链路位于同一网段的3~5个已存在IP，作用是检测节点自身网络是否正常。

（建议配置）3、HA脚本：类似于/etc/init.d/目录下的脚本，主要是规定如何启动、停止和检测业务程序，HA配置之前要准备好，HA软件也提供了主流应用的相关脚本模版供参考，位于/etc/ha.d/resource.d目录下，包括：apache、tomcat、oracle和sybase等。

配置过程：1、集群初始化：cluster-init进入cli,运行cluster-init,然后按向导操作，如：cli:~>cluster-init…(此处打印省略)Please input cluster name:oracle_cluster //自定义集群名称Input the first node name and IP:suse11-sp1-1 192.168.1.192Input the second node name and IP:suse11-sp1-2 192.168.1.193How long between heartbeats(in seconds)[1]:直接回车都是推荐配置，下同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) eth21) bond0Select a multicast heartbeat channel [0, 1]:0 //选取网口心跳链路Another multicast heartbeat channel? (yes/no)[yes]:no //是否再增加一条网口心跳，因下面会配串口心跳，总数已达两条，这里不添加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)[no]:yesDo you want to enable kernel panic ? (yes/no)[no]: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。

2、服务初始化：service-initcli中运行service-init,按向导操作，如：cli:~>service-init…(此处打印省略)Input service name:oracle //输入服务名Is it enabled?(yes/no)[yes]:直接回车Do you want to configure preferred node ? (yes/no)[no]:yes //是否选取服务优先运行节点Please choose preferred node:0) suse11-sp1-11) suse11-sp1-2Select a node: [0, 1]:0Input start time out[60]:直接回车Input stop time out[120]:直接回车Input check interval[30]:直接回车Input check time out[60]:直接回车Input max error count[1]:直接回车Restart after check result is failed?(yes/no)[no]:直接回车Start service anyway when float IP exist?(yes/no)[no]:直接回车Do you want to add a application?

补丁操作步骤及HA相关设置说明

补丁操作步骤及HA相关设置说明

第一部分――补丁操作步骤：1、进行升级前，请进行磁带备份：a、请将磁带放入磁带驱动b、执行如下命令：# smitty mksysbBackup DEVICE or FILE[ ]Create MAP files? noEXCLUDE files? noList files as they are backed up? noGenerate new /image.data file? yesEXPAND /tmp if needed? noDisable software packing of backup? noNumber of BLOCKS to write in a single output []# (Leave blank to use a system default)Esc+4 选择Backup DEVICE or FILE项，使用系统给出的即可，其余参数默认。

2、确认机器当前版本：# lslpp –l |grep bos 查看操作系统AIX版本，取显示内容中列出的最高版本# lslpp –l |grep cluster 查看HA版本，取显示内容中列出的最高版本3、升级总体步骤：说明：AIX＋HA任一版本如果是低于35＋11版本，首先需要先升级至35+11，然后才能进行后续升级操作；如果当前版本是35+11，那么Commit 已经安装的35+11的版本；高于35+11版本的，需要重新依次进行HA17、AIX50/51的升级操作，比如即使AIX已经是50，也需要重新升级50，请务必注意，因为目前广州、深圳、珠海都曾经从50回退过部分软件包，已经是不完整的。

但是超过35+11的就不需要进行Commit 动作了，Commit 只是针对35+11版本；步骤：首先进行HA补丁的升级，升级至4.4.1.17；重启小型机；其次是操作系统AIX的补丁升级，升级至5.1.0.50；重启小型机；再次是操作系统AIX的补丁升级，升级至5.1.0.51(具体的补丁文件含有52字样)；再次重启系统，升级完毕。

配置HA

配置HA

如何配置HA（High Availability）拓扑图：说明：你不需要配置备机，只要配置好第一步，在备机启动后，连接心跳线，备机会自动和主机进行同步并导入配置，导入成功后机器自动重启，重启完成后，配置成功。

注意，备机和主机第一次进行心跳线连接之前，请确认两台机器的操作系统版本一致，即Firmware版本一致。

一．配置HA1.登录需要做第一主机的机器。

2.从左边的菜单栏里面选择，High Availability->Setting3.在右边的页面中，选择启用HA（Enable High Availability）选择框4.在下面的sonicWALL地址选项中，输入第二台机器（备机）的序列号。

（注：备机的序列号可以在机器的铭牌或者system->status下的serial number信息中找到）5.点击Accept按钮保存设置二．配置带状态同步的HA1.以管理员身份登录防火墙2. 选择HA->Advance3. 在Advance菜单下面，如果需要当设备正常后恢复使用第一主机，在Enable Preempt Mode 上面打勾4. 如果升级Firmware时需要备份当前的系统版本和设置时，勾选Generate/OverwriteBackup Firmware and Settings When Upgrading Firmware.5. 当需要调整两台设备通讯间隔时间时，可以修改Heartbeat Interval的值，默认值是5000毫秒进行一次通讯，最小的通讯时间间隔是1000毫秒，值得注意到是，如果间隔时间设的太小，容易引起误操作导致系统切换，特别是在系统负载比较大的时候。

在这种情况下，推荐采用比较大的时间间隔设置6. Failover Trigger Level选项是确定心跳丢失而进行主机切换的数据包的数量7. Probe Level 是关于上行或下行流量间断的时间，SonicWALL推荐使用至少5秒的等待值。

手把手教你使用Newstartha

手把手教你使用Newstartha

手把手教你使用Newstart HA什么是newstart HA？有什么作用？如何搭建？如何使用？当我们接触到新的知识时，会带有一系列的疑问，下面我们带着疑问共同探索一番。

HA，全称High Availability（即高可用性），而newstart HA,作为一款实现高可用性的双机集群软件，用于保证业务持续性运行，在大多数对业务持续性运行（N*24小时）要求比较高的企业，如通信行业的企业，经常会用到。

在简单了解一些概念及其作用后，下面详细讲解如何在linux下双机集群搭建和使用。

一、准备工作工欲善其事必先利其器，要在linux系统下高效地搭建及使用newstarth HA，前期工作要准备好。

1、一些概念：●节点：指运行高可用双机集群软件中的计算机。

●工作链路（work link）：指集群向外提供服务的链路，从服务器到交换机的链路。

●心跳链路（heartbeat link）：维持高可用集群软件内部互联，传送心跳信息的链路。

●服务（service）：是与用户应用相关的一组资源的集合，一般包括：管理用户进程资源的应用脚本(application)，网络资源，存储资源；譬如说用户的一个 Oracle数据库，该服务包括管理Oracle的脚本(用于启动，关闭和监控)， IP地址和所需要 mount的磁盘；服务可以是其中几种或全部资源的组合。

2、硬件（两台物理机子，以下信息相同）：●三张网卡：两张网卡做bonding(工作链路)，一张网卡做心路链路（要保证心跳链路总数不少于2条）●串口：组串口心跳链路，加上上面网口心跳链路，达到2条●磁阵：存放共享数据，建议从中划分一个30~50M的分区用于组建仲裁盘（保障数据安全性的一种机制，可选但推荐，这里为/dev/sdb1）3、软件：●操作系统sles11，主流平台都可支持，如sles9/10/11，redhat5/6，cgslv3/4等●HA版本3.0.1.07,已从newstart官网获取，目前是最新的。
