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 SW_WATCHDOG
  Power switch [NONE]:

  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]: --是否允许远程主机进行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

  Note: Operating a cluster without a remote power switch does not pr
  maximum data integrity guarantees.

  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进行管理,如下所示:
  cluadmin> cluster status
