另外准备好系统光盘，作为yum源
一、先配置Real Server
1. 同步两台Real Server的时间
# hwclock -s
2. 安装 apache
# yum -y install httpd
为两台Real Server提供网页文件
[*]# echo "Real Server 1" > /var/www/html/index.html
[*][root@RS2 ~]# echo "Real Server 2" > /var/www/html/index.html
[*]# vi /etc/httpd/conf/httpd.conf
[*] 更改：ServerName RS1.yue.com
[*]
[*][root@RS2 ~]# vi /etc/httpd/conf/httpd.conf
[*] 更改：ServerName RS2.yue.com
# /etc/init.d/httpd start
3. 在RS1上编辑内核的相关参数(此时配置的内核参数和网卡都是临时生效的，若想要永久有效需要写入相应的配置文件中)
[*]# echo 1 > /proc/sys/net/ipv4/conf/eth0/arp_ignore
[*]# echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore
[*]# echo 2 > /proc/sys/net/ipv4/conf/all/arp_announce
[*]# echo 2 > /proc/sys/net/ipv4/conf/eth0/arp_announce

[*]Real Server 1
设定服务开机自动启动
[*]# chkconfig --add httpd
[*]# chkconfig httpd on
[*]# chkconfig --list httpd
[*]httpd 0:off 1:off 2:on 3:on 4:on 5:on 6:off
4. 在RS2 上做同样的设置
[*]# elinks -dump http://172.16.45.2测试是否正常
[*]Real Server 2
[*]# elinks -dump http://172.16.45.6
[*]Real Server 2
二、配置 Director
1. 双机互信
# ssh-keygen -t rsa
# ssh-copy-id -i ~/.ssh/id_rsa.pub root@node2
2. 主机名
# vi /etc/hosts
172.16.45.11 node1.yue.com node1
172.16.45.12 node2.yue.com node2
3. 时间同步
# hwcolock -s
4.安装上面提到的相关rpm包
# yum -y --nogpgcheck localinstall *.rpm
5. 将rpm包传送给node2并安装
[*]# scp *.rpm node2:/tmp
[*]# ssh node2 'yum -y --nogpgcheck localinstall /tmp/*.rpm'
6. 关闭 heartbeat服务
[*]# chkconfig --list heartbeat
[*]heartbeat 0:off 1:off 2:on 3:on 4:on 5:on 6:off
[*]# chkconfigheartbeat off
[*]# ssh node2 'chkconfigheartbeat off'
7. 提供 corosync的配置文件
[*]# cd /etc/corosync/
[*]# cp corosync.conf.example corosync.conf
[*]
[*]# vi /etc/corosync/corosync.conf
[*]
[*]compatibility: whitetank 兼容性，兼容以前的版本
[*]
[*]totem { 多个corosynce 的节点之间心跳信息的传递方式
[*] version: 2
[*] secauth: off 安全认证
[*] threads: 0 启动几个线程
[*] interface { 通过哪个网络接口传递心跳信息，若有多个接口，则ringnumber不能相同

[*]}
[*]
[*]# 另外添加如下内容：

}
8. 节点密钥文件
[*]# corosync-keygen 生成节点密钥文件
[*]Corosync Cluster Engine Authentication key generator.
[*]Gathering 1024 bits for key from /dev/random.
[*]Press keys on your keyboard to generate entropy.
[*]Writing corosync key to /etc/corosync/authkey.
9. 提供ldirectord的配置文件

11. 启动corosync 服务
[*]# /etc/init.d/corosync start

[*]Aug 05 17:34:18 corosync info: pcmk_startup: Local hostname: node1.yue.com
检查启动过程中是否有错误产生
[*]# grep ERROR: /var/log/corosync.log | grep -v unpack_resources
[*]Aug 05 17:32:45 corosync ERROR: pcmk_wait_dispatch: Child process mgmtd exited (pid=4764, rc=100)
[*]Aug 05 17:34:19 corosync ERROR: pcmk_wait_dispatch: Child process mgmtd exited (pid=4865, rc=100)
如果上面命令执行均没有问题，接着可以执行如下命令启动node2上的corosync
注意：启动node2需要在node1上使用如上命令进行，不要在node2节点上直接启动；
[*]# ssh node2 '/etc/init.d/corosync start'
[*]Starting Corosync Cluster Engine (corosync):
使用如下命令查看集群节点的启动状态：
[*]# crm status

[*]2 Nodes configured, 2 expected votes 2个节点
[*]0 Resources configured. 0个资源
[*]============
[*]
[*]Online: [ node1.yue.com node2.yue.com ]
配置集群的工作属性，禁用stonith
corosync默认启用了stonith，而当前集群并没有相应的stonith设备，因此此默认配置目前尚不可用，这可以通过如下命令验正：
[*]# crm_verify -L
[*]crm_verify: 2012/08/05_17:44:59 ERROR: unpack_resources: Resource start-up disabled since no STONITH resources have been defined
[*]crm_verify: 2012/08/05_17:44:59 ERROR: unpack_resources: Either configure some or disable STONITH with the stonith-enabled option
[*]crm_verify: 2012/08/05_17:44:59 ERROR: unpack_resources: NOTE: Clusters with shared data need STONITH to ensure data integrity
[*]Errors found during check: config not valid
[*]-V may provide more details
我们里可以通过如下方式先禁用stonith：
(当然也可以直接使用命令：# crm configure property stonith-enabled=false 来实现)
[*]# crm 进入crm的交互模式，在每层都可以使用help查看在当前位置可以使用的命令
[*]crm(live)# configure
[*]crm(live)configure# property stonith-enabled=false
[*]crm(live)configure# verify 检查语法
[*]crm(live)configure# commit 提交
[*]crm(live)configure# show
[*]node node1.yue.com
[*]node node2.yue.com
[*]property $id="cib-bootstrap-options" \
[*] dc-version="1.1.5-1.1.el5-01e86afaaa6d4a8c4836f68df80ababd6ca3902f" \
[*] cluster-infrastructure="openais" \
[*] expected-quorum-votes="2" \
[*] stonith-enabled="false" stonith已经被禁用
[*]
[*]
[*]上面的crm，crm_verify命令是1.0后的版本的pacemaker提供的基于命令行的集群管理工具；可以在集群中的任何一个节点上执行。
三、为集群添加集群资源
corosync支持heartbeat，LSB和ocf等类型的资源代理，目前较为常用的类型为LSB和OCF两类，stonith类专为配置stonith设备而用；
可以通过如下命令查看当前集群系统所支持的类型：
[*]# crm ra classes
[*]heartbeat
[*]lsb
[*]ocf / heartbeat pacemaker
[*]stonith
如果想要查看某种类别下的所用资源代理的列表，可以使用类似如下命令实现：
# crm ra list lsb
# crm ra list ocf heartbeat
# crm ra list ocf pacemaker
# crm ra list stonith
# crm ra info ]resource_agent
例如：
# crm ra info ocf:heartbeat:IPaddr
[*]# crm
[*]crm(live)# resource
[*]crm(live)resource# status 查看资源的状态
[*] Resource Group: web
[*] Web_server (lsb:httpd) Started
[*] WebIP(ocf::heartbeat:IPaddr) Started
[*]
[*]crm(live)resource# stop web 停止一个资源
[*]crm(live)resource# status
[*] Resource Group: web
[*] Web_server (lsb:httpd) Stopped
[*] WebIP(ocf::heartbeat:IPaddr) Stopped
[*]crm(live)resource#
[*]
[*]
[*]crm(live)configure# delete web 删除一个组
1. 接下来要为web集群创建一个IP地址资源，以在通过集群提供web服务时使用；这可以通过如下方式实现：
定义资源的语法：
[*]primitive[:[:]]
[*]
[*]
[*] ...]
[*]
[*]op_type :: start | stop | monitor
[*]
[*]例子：
[*] primitive apcfence stonith:apcsmart \
[*] params ttydev=/dev/ttyS0 hostlist="node1 node2" \
[*] op start timeout=60s \
[*]
[*] op monitor interval=30m timeout=60s
[*]定义IP资源时的一些参数：
[*]Parameters (* denotes required, [] the default):
[*]ip* (string): IPv4 address
[*] The IPv4 address to be configured in dotted quad notation, for example "192.168.1.1".
[*]nic (string, ): Network interface
[*] The base network interface on which the IP address will be brought
[*]cidr_netmask (string): Netmask
[*] The netmask for the interface in CIDR format. (ie, 24), or in dotted quad notation255.255.255.0).
[*]broadcast (string): Broadcast address
[*]lvs_support (boolean, ): Enable support for LVS DR
[*]Operations' defaults (advisory minimum):
[*] start timeout=20s
[*] stop timeout=20s
[*] monitor interval=5s timeout=20s
