HP-UX MC/SG Cluster 구성하기

1. Cluster 대상 VG 생성 및 vglock 생성

대상 VG 생성후 아래 처럼 vglock 을 생성합니다.    

# mkdir /dev/vglock
# mknod /dev/vglock c 64 0x100000
# vgcreate /dev/vglock /dev/dsk/cxtxdx

2. cmnodelist 생성

/ .rhosts 에도 구성 하는동안 + 를 추가해줍니다.

# vi /etc/cmcluster/cmclnodelist
node1         root
node2         root

3. .asc (cluster configration information) file 생성

-C 뒤에 .asc file name 을 주고 -n 에 cluster 구성할 node 들을 써줍니다.

정보를 수집한후에 .asc file 이 생성됩니다.

# cmquerycl -v -C mcsg_db_cluster.asc -n node1 -n node2

Begin checking the nodes...

Writing cluster data to test_pa_db_cluster.asc.

4. .asc file 수정

필요한 정보를 수정 합니다.. .asc file 에 대해서는 추후에.. 급하신분들 리플 달아 주시면 알려 드릴께요 ^^;;

5. pkg templete 생성

# mkdir -p /etc/cmcluster/node1_pkg1
# cd /etc/cmcluster/node1_pkg1
# cmmakepkg -s node1_pkg1.cntl
# cmmakepkg -p node1_pkg1.conf

6. pkg file 수정

수정할 내용은 아래 정도 입니다.. 환경에 맞게 하시면 됩니다.

.conf

# grep -Ev "^$|^#" *.conf

PACKAGE_NAME    node1_pkg1                     

PACKAGE_TYPE                    FAILOVER

FAILOVER_POLICY                 CONFIGURED_NODE

FAILBACK_POLICY                 MANUAL

NODE_NAME       node1

NODE_NAME       node2

AUTO_RUN                        YES

LOCAL_LAN_FAILOVER_ALLOWED      YES

NODE_FAIL_FAST_ENABLED          NO

RUN_SCRIPT                  /etc/cmcluster/node1_pkg1/node1_pkg1.cntl                            

RUN_SCRIPT_TIMEOUT              NO_TIMEOUT

HALT_SCRIPT                  /etc/cmcluster/node1_pkg1/node1_pkg1.cntl

.cntl

# cat *.cntl |grep -Ev "^$|^#"

log_file=${SG_SCRIPT_LOG_FILE:-$0.log}

function customer_defined_run_cmds

{

: # do nothing instruction, because a function must contain some command.

        test_return 51

}

       

function customer_defined_halt_cmds

{

: # do nothing instruction, because a function must contain some command.

        test_return 52

}

5. configration check 및 cluster apply

# cmcheckconf -v -C mcsg_db_cluster.asc -P ./node1_pkg1/node1_pkg1.conf -P ./node2_pkg1/node2_pkg1.conf
# cmapply -C mcsg_db_cluster.asc -P ./node1_pkg1/node1_pkg1.conf -P ./node2_pkg1/node2_pkg1.conf
# cmviewcl
