基于heartbeat v2 crm实现HA高可用性的 LAMP+wordpress
一 Heartbeat 基本理论提供冗余系统：
HA Cluster：为提升系统调用性，组合多台主机构建成为的集群；
split brain, partitioned cluster
vote system：投票系统
HA中的各节点无法探测彼此的心跳信息时，必须无法协调工作；此种状态即为partitioned cluster；
少数服从多数的原则：quorum
with quorum > total/2
without quorum M；
N-N：N个节点，N个服务；
资源运行的倾向性：
rgmanager:
failover domain, node priority
pacemaker：
资源黏性：运行于当前节点的倾向性；
资源约束：
位置约束：资源对运行于某节点的倾向性
inf: 正无穷
-inf: 负无穷
n:
-n:
排列约束：资源运行于一处的倾向性
inf
-inf
n
-n
顺序约束：启动的先后顺序
A --> B --> C
C --> B --> A
DC: Designated Coordinator
corosync:
AIS: Application Interface Standard,
SA Forum: OpenAIS
OpenAIS: 提供了一种集群模式，包含集群框架、集群成员管理、通信方式、集群监测，但没有集群资源管理功能；
组件包括：AMF, CLM, CPKT, EVT等；分支不同，包含的组件略有区别；
分支：picacho, whitetank, wilson,
corosync (集群管理引擎)
只是openais的一个子组件；
分裂成为两个项目：
corosync, wilson(ais的接口标准)
CentOS 5:
cman + rgmanager
CentOS 6:
cman + rgmanager
corosync + pacemaker
命令行管理工具：
crmsh: suse, CentOS 6.4-
pcs: RedHat, CentOS 6.5+
crm的常用子命令：
status
node
configure
ra
resource
configure常用的子命令：
primitive
group
clone
ms
location
colocation
order
show
property
primitiveclass:provider:ra params param1=value1 param2=value2 op op1 param1=value op op2 parma1=value1
二 测试heartbeat+httpd
基本环境设置
10.10.10.50/24 node1.test.comnode1
10.10.10.51/24 node2.test.comnode2
10.10.10.5/24 vip
关闭iptables
service iptables stop
chkconfig iptables off 关闭selinx
vim /etc/selinux/config
SELINUX=disabled 修改主机名
vim /etc/sysconfig/network
HOSTNAME=node2.test.com
vim /etc/hosts
10.10.10.50 node1.test.comnode1
10.10.10.51 node2.test.comnode2
reboot# uname -n
node1.test.com
# uname -n
node2.test.com 安装httpd
yum install httpd
# vim /var/www/html/index.html
node1.test.com 10.10.10.50
# vim /var/www/html/index.html
node2.test.com 10.10.10.51
service httpd start 测试打开 http://10.10.10.50
http://10.10.10.51
service httpd stop 准备ssh 信任(不用输账号密码进入系统)
cd ~
ssh-keygen -t rsa
ssh-copy-id localhost
ssh node2 cat ~/.ssh/id_rsa.pub >>.ssh/authorized_keys
scp .ssh/authorized_keysnode2:~/.ssh/
安装heartbeat
设置epel源libnet在epel
wget http://mirrors.aliyun.com/epel/6/x86_64/epel-release-6-8.noarch.rpm
rpm -ivh epel-release-6-8.noarch.rpm
yum install net-snmp-libs libnet PyXML libtool-ltdl
rpm -ivh heartbeat-2.1.4-12.el6.x86_64.rpm heartbeat-pils-2.1.4-12.el6.x86_64.rpm heartbeat-stonith-2.1.4-12.el6.x86_64.rpm 配置heartbeat
cd /etc/ha.d/
cp -r /usr/share/doc/heartbeat-2.1.4//etc/ha.d/
cp ./heartbeat-2.1.4/{ha.cf,authkeys,haresources} ./
chmod 600 authkeysvim authkeys

service heartbeat start;ssh node2 service heartbeat start 查看实时生成的日志
tail -f /var/log/ha-debug 检测运行状态,所有资源在node1上 ，node2 上只有heartbeat服务

systemctl stop firewalld
systemctl disable firewalld 关闭selinx
vim /etc/selinux/config

# service mysqld stop
# umount /data 安装 heartbeat-gui
yum install pygtk2-libglade xorg-x11-xauth
rpm -ivh heartbeat-gui-2.1.4-12.el6.x86_64.rpmecho "password" | passwd --stdin haclusteryum install xorg-x11-xauth #如果未安装图型系统，要安装此组件，要不xshell报错
vim /etc/ha.d/ha.cf
crm on
service heartbeat start;ssh node2 service heartbeat start 在xshell 执行
hb_gui& 连接127.0.0.1 安装gui默认生成hacluster 用户， 默认无密码
请使用echo "password" | passwd --stdin hacluster 创建密码

连接成功后如图显示
http://s3.运维网.com/wyfs02/M00/74/DA/wKioL1Yso1Gze6EWAAKZHObjP-8602.jpg
开始添加资源 ，些次添加资源组 名为wordpress
http://s3.运维网.com/wyfs02/M02/74/DA/wKioL1Yso1WA6w8AAAJpcTfpwKw005.jpg
添加第一个资源名为 ha_ip
类型为IPaddr参数为ip10.10.10.5
http://s3.运维网.com/wyfs02/M01/74/DE/wKiom1YsoyfCSILOAAQaKD0P0tA867.jpg
http://s3.运维网.com/wyfs02/M01/74/DE/wKiom1YsoyqiGShhAAIk0hGXwNw067.jpg
添加第二个资源名为ha_nfs_mysql ,和我们之前测试时使用的参数一至，为mysql的共享存储
类型为Filesystem
参数为device 10.10.10.60:/home/data/mysql
directory /data
fstype nfs
http://s3.运维网.com/wyfs02/M01/74/DA/wKioL1Yso17yIBRiAARvpsiH7pQ984.jpg
添加第三个资源名为ha_nfs_httpd ,和我们之前测试时使用的参数一至，为httpd的共享存储
类型为Filesystem
参数为device 10.10.10.60:/home/data/html
directory /var/www/html
fstype nfs
http://s3.运维网.com/wyfs02/M00/74/DA/wKioL1Yso2LiIBaZAARvaIyiVr8613.jpg
添加第四个资源名为ha_mysql
类型为我们安装的mysqld ,不需要参数
http://s3.运维网.com/wyfs02/M02/74/DE/wKiom1YsozfCG7MVAAQEVpUbnLw372.jpg
添加第五个资源名为ha_httpd
类型为我们安装的httpd ,不需要参数
http://s3.运维网.com/wyfs02/M02/74/DA/wKioL1Yso2ri9PPCAAQ-PoG5mnI153.jpg
添加主机colocations ，为资源起动所有的位置
第一个为，ha_ipha_nfs_mysql 必须在同一个node上
http://s3.运维网.com/wyfs02/M00/74/DE/wKiom1Ysoz3AF8SXAAQtBOHztsI613.jpg
第一个为，ha_ipha_nfs_httpd 必须在同一个node上
http://s3.运维网.com/wyfs02/M02/74/DE/wKiom1Yso0LwQQDeAAQg6v5yRSQ728.jpg
第一个为，ha_mysqlha_nfs_mysql 必须在同一个node上
http://s3.运维网.com/wyfs02/M00/74/DA/wKioL1Yso3bgQ1FFAAQ2QqZ4r_w649.jpg
第一个为，ha_httpdha_nfs_httpd 必须在同一个node上
http://s3.运维网.com/wyfs02/M01/74/DE/wKiom1Yso0zxY1QzAARRt1jSgag706.jpg
以上设置保证所有资源启动在同一个node上，根据需要修改。
添加资源order，意为资源的启动顺序
第一个为， ha_ip 比ha_nfs_mysql先启动
如果不能启动ha_ip ，则不启动ha_nfs_mysql
停止时，先停止ha_nfs_mysql ,后停止ha_ip
如果不能停止ha_nfs_mysql,则不停止ha_ip
http://s3.运维网.com/wyfs02/M01/74/DA/wKioL1Yso4PjvHfNAAQndpj25o0458.jpg
第二个为， ha_ip 比ha_nfs_httpd先启动
如果不能启动ha_ip ，则不启动ha_nfs_httpd
停止时，先停止ha_nfs_httpd ,后停止ha_ip
如果不能停止ha_nfs_httpd,则不停止ha_ip
http://s3.运维网.com/wyfs02/M00/74/DE/wKiom1Yso1qC6cy7AAQFxMY6NAs185.jpg
第三个为， ha_nfs_mysql 比ha_mysql先启动
如果不能启动ha_nfs_mysql ，则不启动ha_mysql
停止时，先停止ha_mysql ,后停止ha_nfs_mysql
如果不能停止ha_mysql,则不停止ha_nfs_mysql
http://s3.运维网.com/wyfs02/M02/74/DE/wKiom1Yso1-SsAM5AAREJ6BdY-E178.jpg
第四个为， ha_nfs_httpd 比ha_httpd先启动
如果不能启动ha_nfs_httpd ，则不启动ha_httpd
停止时，先停止ha_httpd,后停止ha_nfs_httpd
如果不能停止ha_httpd,则不停止ha_nfs_httpd
http://s3.运维网.com/wyfs02/M02/74/DA/wKioL1Yso5byjxfXAAQqzJw8jaA468.jpg
右键ha_wordpress ，start 启动ha_wordpress资源
以上配置启动顺序为 ha_ip --> ha_nfs_mysql --> ha_mysql
ha_ip --> ha_nfs_httpd--> ha_httpd
http://s3.运维网.com/wyfs02/M01/74/DE/wKiom1Yso2qi74xjAANvdP-Zk1w833.jpg
http://s3.运维网.com/wyfs02/M02/74/DB/wKioL1Yso52j1VozAAOXNQybBvU544.jpg
右键节点node2 standby
http://s3.运维网.com/wyfs02/M00/74/DE/wKiom1Yso3HSq1HRAAOhYyT1uLo785.jpg
资源全部转移动node1
