Red Hat Cluster Manager
安裝操作系統，選擇組件advance server，安裝LVS部分。
兩台主機，主機名為haha和hehe
主機haha的本地ip地址為net0:192.168.2.11，net1:192.168.2.14
主機hehe的本地ip地址為net0:192.168.2.12，net1:192.168.2.16
（主機網絡連線只能用直連線進行連接，不能用交叉線連接，否則雙機不能進行監控）
修改/etc/hosts文件，封掉localhost行的內容，寫入本地主機、對方主機和虛擬主機相應的ip地址和主機名：（兩台主機配置相同）
192.168.2.11 haha
192.168.2.12 hehe
192.168.2.13 xixi
進入/etc/sysconfig/rawdevices文件，增加兩行內容：（兩台主機設置相同）
/dev/raw/raw1 /dev/sdb1
/dev/raw/raw2 /dev/sdb2
以上兩行是LVS需要的兩個裸設備作為系統監控使用，每個裸設備的空間不能小於10M。當然需要fdisk建立兩個兩個相應的設備。
然後從起主機，進入/sbin下，./cluconfig進行cluster的配置：
Red Hat Cluster Manager Configuration Utility (running on haha) --haha為本地主機名
Enter cluster name [Red Hat Cluster Manager]:xixi --xixi為虛擬主機名
Enter IP address for cluster alias [NONE]:192.168.2.13 --地址為虛擬地址
--------------------------------
Information for Cluster Member 0
--------------------------------
Enter name of cluster member [haha]: --本地成員，回車即可
Enter number of heartbeat channels (minimum = 1) [1]: 2 --兩塊網卡心跳線（也可串口心跳）
Channel type: net or serial [net]: --第一塊網卡做心跳
Enter hostname of the cluster member on heartbeat channel 0 [haha]: --心跳線成員名稱
Channel type: net or serial [net]: --第二塊網卡做心跳線
Enter hostname of the cluster member on heartbeat channel 1:hehe --另外一個成員名稱
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 --對方成員名
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]: --對配置信息進行保存
Save the cluster member information? yes/no [yes]:
Writing to configuration file...done
Configuration information has been saved to /etc/cluster.conf.

Setting up Quorum Partitions
----------------------------
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]: --是否允許遠程主機進行cluster監視訪問
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.
本地主機配置完成
進入對方主機的/sbin目錄，執行cluconfig –init=/dev/raw/raw1顯示信息如下：
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
Looking for host hehe (may take a few seconds)...
Information about Quorum Partitions
Information About the Power Switch That Power Cycles Member 'haha'
Note: Operating a cluster without a remote power switch does not pr
maximum data integrity guarantees.

Press <Return> to continue. --按回車繼續

Execute "/sbin/service cluster start" to start the cluster software.
這時，雙機軟件基本配置已經完成，在兩台主機上分別運行service cluster start啟動服務
通過cluadmin進行管理，如下所示：
cluadmin> cluster status
Cluster Status Monitor (xixi) 11:16:11
Cluster alias: xixi
========================= M e m b e r S t a t u s ==========================
Member Status Node Id Power Switch
-------------- ---------- ---------- ------------
haha Up 0 Good
hehe Up 1 Good
========================= H e a r t b e a t S t a t u s ====================
Name Type Status
------------------------------ ---------- ------------
haha <--> hehe network ONLINE
========================= S e r v i c e S t a t u s ========================

通過狀態可以看到雙機狀態正常，但未加入任何服務，通過help可以看到幫助：
cluadmin> help
cluster service apropos clear help version exit quit
cluadmin> service add --加入一個服務
Service name: disk --服務名稱
Preferred member [None]:haha --首選成員
