SUSE 9 heartbeat双机集群配置
环境：两台SUSE 9,同时已经搭建好apache
主机名：node1(172.16.11.88/255.255.0.0) --主用
node2(172.16.12.89/255.255.0.0) --备用
心跳网卡：node1-10.10.10.200
node2-10.10.10.201
配置IP地址：略
操作步骤：
1、在node1上配置/etc/hosts和/etc/HOSTNAME两个配置文件，内容如下：
node1:/etc # more /etc/HOSTNAME
node1
node1:/etc # more /etc/hosts
。。。。。。。。
。。。。。。。。
10.10.10.200 node1.com node1
172.16.11.88 node1.com node1
2、在node2上配置/etc/hosts和/etc/HOSTNAME两个配置文件，内容如下：
node2:~ # more /etc/HOSTNAME
node2
node2:~ # more /etc/hosts
。。。。。。。。
。。。。。。。。
10.10.10.201 node2.com node2
172.16.12.89 node2.com node2
3、分别对两台机器进行重新启动 init 6
4、由于安装SUSE时是完全安装，已经自带有heartbeat软件，只需进行配置文件的拷贝和修改即可
这里只需在node1上操作，之后采用scp将配置好的文件传到备用node2即可
node1:~ # rpm -q heartbeat -d

. .. README.config authkeys conf ha.cf harc haresources rc.d resource.d shellfuncs
node1:/etc/ha.d # cp ha.cf ha.cf-bak
编辑ha.cf,去掉如下字段前的#即可
node1:/etc/ha.d # more ha.cf
debugfile /var/log/ha-debug 该文件保存heartbeat的调试信息
logfile /var/log/ha-log heartbeat的日志文件
logfacility local0
keepalive 2 心跳的时间间隔，默认时间单位为秒
deadtime 30 超出该时间间隔未收到对方节点的心跳，则认为对方已经死亡。
warntime 10 超出该时间间隔未收到对方节点的心跳，则发出警告并记录到日志中。
initdead 120 在某些系统上，系统启动或重启之后需要经过一段时间网络才能正常工作，该选项用于解决这种情况产生的时间间隔。取值至少为deadtime 的两倍。
udpport 694 设置广播通信使用的端口，694为默认使用的端口号。
baud 19200 设置串行通信的波特率。
serial /dev/ttyS0 # Linux 选择串行通信设备，用于双机使用串口线连接的情况。如果双机使用以太网连接，则应该关闭该选项。
bcast eth1 # Linux 设置广播通信所使用的网络接口卡。
auto_failback on heartbeat的两台主机分别为主节点和从节点。主节点在正常情况下占用资源并运行所有的服务，
在该选项设为on的情况下，一旦主节点恢复运行，则自动获取
node node1 --经过了修改
node node2 --经过了修改
ping 172.16.13.90 用于心跳测试
respawn hacluster /usr/lib/heartbeat/ipfail 指定与heartbeat一同启动和关闭的进程，该进程被自动监视，
编辑haresource，添加如下内容
node1:/etc/ha.d # more haresources
node1 IPaddr::172.16.13.90 apache
编辑authkeys,注释如下字段前#
node1:/etc/ha.d # more authkeys
auth 1
1 crc
5、建立http服务切换启动脚本的链接文件
node1:/etc/ha.d/resource.d # mv apache apache-bak (node2上也要做这步)
node1:/etc/ha.d/resource.d # ln -s /var/local/apache/bin/apachectl apache (node2上也要做这步)
6、为保证机器重启后heartbeat能够自动启动，建立如下链接文件 (node2上也要做这步)
node1:/etc/rc.d/rc0.d # ln -s /etc/init.d/heartbeat K05heartbeat
node1:/etc/rc.d/rc0.d # cd ..
node1:/etc/rc.d # cd rc3.d
node1:/etc/rc.d/rc3.d # ln -s /etc/init.d/heartbeat S75heartbeat
node1:/etc/rc.d/rc3.d # cd ..
node1:/etc/rc.d # cd rc5.d
node1:/etc/rc.d/rc5.d # ln -s /etc/init.d/heartbeat S75heartbeat
node1:/etc/rc.d/rc5.d # cd ..
node1:/etc/rc.d # cd rc6.d
node1:/etc/rc.d/rc6.d # ln -s /etc/init.d/heartbeat K05heartbeat
7、使用scp将配置好的文件传送到node2上
node1:/etc/ha.d # scp ha.cf haresources authkeys
8、测试一
在node1上启动heartbeat
node1:/etc/init.d # ./heartbeat start
在真实机PING提供服务的集群的地址，不会马上通，
C:\Documents and Settings\Administrator>ping 172.16.13.90 -t

注意：先停掉node2，再停掉node1
然后再启动node2，需要等1分钟左右才能由node2获取到集群地址
再来启动node1，这个时候node2会释放集群地址，由node1获得
9、测试二，http服务切换
在node1上查看http已经启动
node1:/etc/init.d # ps -ef|grep httpd
root 17653 1 0 14:48 ? 00:00:00 /var/local/apache/bin/httpd -k start
daemon 17654 17653 0 14:48 ? 00:00:00 /var/local/apache/bin/httpd -k start

root 17663 6349 0 14:48 pts/0 00:00:00 grep httpd
停掉node1的heartbeat,会发现http也已经被关闭
node1:/etc/init.d # ./heartbeat stop
Stopping High-Availability services done
node1:/etc/init.d # ps -ef|grep httpd
root 18705 6349 0 15:18 pts/0 00:00:00 grep httpd
回到node2上查看，发现http被带动起来，在这之前http是没有启动的
node2:/etc/ha.d # ps -ef|grep httpd
root 22995 1 0 15:22 ? 00:00:00 /var/local/apache/bin/httpd -k start

daemon 23008 22995 0 15:22 ? 00:00:00 /var/local/apache/bin/httpd -k start

root 23106 8594 0 15:23 pts/2 00:00:00 grep httpd
再启动node1的heartbeat，http也同时被启动
node1:/etc/init.d # ./heartbeat start
Starting High-Availability servicesheartbeat: 2009/08/21_15:21:12 info: **************************

done
node1:/etc/init.d #
node1:/etc/init.d # ps -ef|grep httpd
root 18905 1 0 15:21 ? 00:00:00 /var/local/apache/bin/httpd -k start

root 18915 6349 0 15:21 pts/0 00:00:00 grep httpd
node2的http已经被关闭
node2:/etc/ha.d # ps -ef|grep httpd
root 24098 8594 0 15:25 pts/2 00:00:00 grep httpd
在切换过程中总会发现如下的字样
