Red Hat Cluster Manager
安装操作系统，选择组件advance server，安装LVS部分。
两台主机，主机名为haha和hehe
主机haha的本地ip地址为net0:192.168.2.11，net1:192.168.2.14
主机hehe的本地ip地址为net0:192.168.2.12，net1:192.168.2.16
（主机网络连线只能用直连线进行连接，不能用交叉线连接，否则双机不能进行监控）
修改/etc/hosts文件，封掉localhost行的内容，写入本地主机、对方主机和虚拟主机相应的ip地址和主机名：（两台主机配置相同）
192.168.2.11 haha
192.168.2.12 hehe
192.168.2.13 xixi
进入/etc/sysconfig/rawdevices文件，增加两行内容：（两台主机设置相同）
/dev/raw/raw1 /dev/sdb1
/dev/raw/raw2 /dev/sdb2
以上两行是LVS需要的两个裸设备作为系统监控使用，每个裸设备的空间不能小于10M。当然需要fdisk建立两个两个相应的设备。
然后从起主机，进入/sbin下，./clUConfig进行cluster的配置：
Red Hat Cluster Manager Configuration Utility (running on haha) --haha为本地主机名
Enter cluster name [Red Hat Cluster Manager]:xixi --xixi为虚拟主机名
Enter IP address for cluster alias [NONE]:192.168.2.13 --地址为虚拟地址
--------------------------------
Information for Cluster Member 0
--------------------------------
Enter name of cluster member [haha]: --本地成员，回车即可
Enter number of heartbeat channels (minimum = 1) [1]: 2 --两块网卡心跳线（也可串口心跳）
Channel type: net or serial [net]: --第一块网卡做心跳
Enter hostname of the cluster member on heartbeat channel 0 [haha]: --心跳线成员名称
Channel type: net or serial [net]: --第二块网卡做心跳线
Enter hostname of the cluster member on heartbeat channel 1:hehe --另外一个成员名称
Information about Quorum Partitions
Enter PRimary Quorum Partition [/dev/raw/raw1]:
Enter Shadow Quorum Partition [/dev/raw/raw2]:
Information About the Power Switch That Power Cycles Member 'haha'
Choose one of the following power switches:
o NONE
o RPS10
o BAYTECH
o APCSERIAL
o APCMASTER
o WTI_NPS
o SW_WATCHDOG
Power switch [NONE]:
--------------------------------
Information for Cluster Member 1
--------------------------------
Enter name of cluster member:hehe --对方成员名
Enter hostname of the cluster member on heartbeat channel 0: hehe
Enter hostname of the cluster member on heartbeat channel 1: haha
Information about Quorum Partitions
Enter Primary Quorum Partition [/dev/raw/raw1]:
Enter Shadow Quorum Partition [/dev/raw/raw2]:
Information About the Power Switch That Power Cycles Member 'hehe'
Choose one of the following power switches:
o NONE
o RPS10
o BAYTECH
o APCSERIAL
o APCMASTER
o WTI_NPS
o SW_WATCHDOG
Power switch [NONE]:
Save the cluster member information?
yes/no [yes]: --对配置信息进行保存

Running cludiskutil -I to initialize the quorum partitions: done
Saving configuration information to quorum partitions: done
Do you wish to allow remote monitoring of the cluster? yes/no [yes]: --是否答应远程主机进行cluster监视访问
Configuration on this member is complete.
To configure the next member, invoke the following command on that system:
# /sbin/cluconfig --init=/dev/raw/raw1
Refer to the Red Hat Cluster Manager Installation and Administration Guide
for details.
本地主机配置完成
进入对方主机的/sbin目录，执行cluconfig –init=/dev/raw/raw1显示信息如下：
Information about Channel 0
/sbin/cluconfig: [: haha: unary Operator eXPected
Looking for host haha (may take a few seconds)...
Information about Channel 1
/sbin/cluconfig: [: hehe: unary operator expected

Save the cluster member information?
yes/no [yes]: --是否进行保存
Writing to configuration file...done

----------------------------------------------------------------
Configuration on this member is complete.
Execute "/sbin/service cluster start" to start the cluster software.
这时，双机软件基本配置已经完成，在两台主机上分别运行service cluster start启动服务
通过cluadmin进行治理，如下所示：
cluadmin> cluster status
Cluster Status Monitor (xixi) 11:16:11
Cluster alias: xixi
