HACMP概念
HACMP概念
- Cluster
- Node
- Topology
- Resource
- Resource group 用于系统保护的一组资源集合
- Application server 受Hacmp控制的一组应用的启动和停止脚本
- Reintegration 一个发生失败的节点，重新加入cluster
- Global ODM 通过网络，同步到cluster中的所有Node的配置信息
- Synchronization 从cluster中单点升级global odm到所有节点的进程
- Event
Hacmp的软件构成
- Clstrmgr
- Clsmuxpd
- Clinfo
- Cllockd
- Event scripts
Hacmp的软件工具
TaskGuide
Clverify 软件和配置检测
Clstat 图形化显示cluster工具
Hacmp处理的错误
仅处理三种类型错误
节点失败 cascading，优先级切换，可自动回切和手动回切，应该人为触发坏了自动切，好了手动切/rotatiing/concurrent
网络失败
网卡失败
不适合使用Hacmp的情况
系统不能忍受任何时间的停顿
7x24小时不停
性命危机相关的系统
适合容错需求的
没有一个安全的环境，许多用户要求以root权利登录
环境经常发生变化，缺少熟练的系统管理员
cluster集群部署
1.安装操作系统
2.打bundle(app-dev cde server openssh)
3.安装clvm
4.升级操作系统(update_all)
5.hosts iptables-ip地址规划
检查主机名和ip地址
hostname/ipconfig -a
6.创建集群
smitty hacmp
extened configuration
extended topology configuration
configure an hacmp cluster
add an hacmp cluster
7.add node
smitty hacmp
extened configuration
extended topology configuration
configure hacmp nodes
add node
8.discover
smitty hacmp
extened configuration
discover hacmp-related information from configure node
9.add network
smitty hacmp
extened configuration
extended topology configuration
configure hacmp networks
10.add interface
smitty hacmp
extened configuration
extended topology configuration
configure
11.add resource
smitty hacmp
extened configuration
extened resource configuration
hacmp extended resource configuration
configure hacmp service ip labels/address
add a service ip lable/address
configurable on multiple nodes
net_ether_01
12.add resource group
13.resouce -> rg
14.verify and sync
smitty hacmp
extened configuration
extended verifycation and sync
15.start service
smitty hacmp
system management (c-spoc)
manage hacmp service
start cluster service
show cluster service 保证下面三个是active的，否则集群起不来
smitty hacmp
system management (c-spoc)
hacmp resource group and application management
show the current state of application and resource groups
16.test
smitty hacmp
system management (c-spoc)
hacmp resource group and application management
move a resource group to another node/site
move resource groups to another node
17.停止集群服务
smitty hacmp
system management (c-spoc)
manage hacmp services
stop cluster services
