2、客户端访问共享存储（all nodes）
如下所示，集群节点作为iscsi client连接访问共享存储，并可以将共享磁盘，作为本地磁盘访问：
[root@node201 ~]# /usr/sbin/iscsiadm -m node -T iqn.2024-08.pip.cc:server -p 192.168.1.203 --login
Logging in to [iface: default, target: iqn.2024-08.pip.cc:server, portal: 192.168.1.203,3260] (multiple)
Login to [iface: default, target: iqn.2024-08.pip.cc:server, portal: 192.168.1.203,3260] successful.
[root@node201 ~]# fdisk -l
Disk /dev/sdd: 134 MB, 134217728 bytes, 262144 sectors
Disk /dev/sde: 134 MB, 134217728 bytes, 262144 sectors
Disk /dev/sdf: 2343 MB, 2343757824 bytes, 4577652 sectors
Disk /dev/sdg: 8867 MB, 8867020800 bytes, 17318400 sectors
二、配置集群环境
参考文档：https://eco.dameng.com/document/dm/zh-cn/pm/dsc-build.html
1、集群规划
如下所示，集群实例配置规划：
在 4 块共享磁盘中：2 块较小的磁盘（1G）用于创建 DCR、VOTE 磁盘；2 块较大的磁盘（2T）用于创建 ASM 磁盘组（数据磁盘组 DMDATA 和联机日志磁盘组 DMLOG）。
2、配置用户（all nodes）
[root@node201 ~]# groupadd -g 2001 dmdba
[root@node201 ~]# useradd -u 2001 -g dmdba dmdba
[root@node201 ~]# passwd dmdba
Changing password for user dmdba.
New password:
BAD PASSWORD: The password is shorter than 8 characters
Retype new password:
passwd: all authentication tokens updated successfully.
3、集群目录规划
[root@node201 ~]# mkdir -p /home/dmdba/dmdsc # DSC 环境搭建的目录
[root@node201 ~]# mkdir -p /home/dmdba/dmdsc/bin
[root@node201 ~]# mkdir -p /home/dmdba/dmdsc/data/DSC01 #配置文件存储目录（node201）
[root@node201 ~]# mkdir -p /home/dmdba/dmdsc/data/DSC02 #配置文件存储目录（node202）
4、创建共享存储（裸设备、udev设备）
1）通过 scsi_id 获取磁盘信息（两个节点获取信息一致）
[root@node201 ~]# /usr/lib/udev/scsi_id -g -u /dev/sdd
36001405027e52d2bbfa49148b4dcc546
[root@node201 ~]# /usr/lib/udev/scsi_id -g -u /dev/sde
36001405d8832f16856e45b0b44cd9252
[root@node201 ~]# /usr/lib/udev/scsi_id -g -u /dev/sdf
360014058606671082694fca897a2404d
[root@node201 ~]# /usr/lib/udev/scsi_id -g -u /dev/sdg
36001405067e2cf5c3a046d299ee74301
2）配置udev规则
[root@node201 ~]# cat /etc/udev/rules.d/66-dmdevices.rules
## DCR磁盘配置,且在软链接之前创建文件夹 /dev_DSC2
KERNEL=="sd*",SUBSYSTEM=="block",PROGRAM=="/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",RESULT=="36001405027e52d2bbfa49148b4dcc546",SYMLINK+="DCR", OWNER="dmdba", GROUP="dmdba", MODE="0660", RUN+="/bin/sh -c 'chown dmdba:dmdba /dev/$name;mkdir -p /dev_DSC2; ln -s /dev/DCR /dev_DSC2/DCR'"
## VOTE 磁盘配置
KERNEL=="sd*",SUBSYSTEM=="block",PROGRAM=="/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",RESULT=="36001405d8832f16856e45b0b44cd9252",SYMLINK+="VOTE", OWNER="dmdba", GROUP="dmdba", MODE="0660", RUN+="/bin/sh -c 'chown dmdba:dmdba /dev/$name; ln -s /dev/VOTE /dev_DSC2/VOTE'"
## DMLOG 磁盘配置，且在搭建完成之后，将权限直接赋予 dmdba组的dmdba用户
KERNEL=="sd*",SUBSYSTEM=="block",PROGRAM=="/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",RESULT=="360014058606671082694fca897a2404d",SYMLINK+="DMLOG", OWNER="dmdba", GROUP="dmdba", MODE="0660", RUN+="/bin/sh -c 'chown dmdba:dmdba /dev/$name; ln -s /dev/DMLOG /dev_DSC2/DMLOG ; chown -R dmdba:dmdba /dev_DSC2'"
## DMDATA 磁盘配置
KERNEL=="sd*",SUBSYSTEM=="block",PROGRAM=="/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",RESULT=="36001405067e2cf5c3a046d299ee74301",SYMLINK+="DMDATA", OWNER="dmdba", GROUP="dmdba", MODE="0660", RUN+="/bin/sh -c 'chown dmdba:dmdba /dev/$name; ln -s /dev/DMDATA /dev_DSC2/DMDATA'"
3）创建磁盘链接
[root@node201 ES]# systemctl restart systemd-udev-trigger
[root@node201 ~]# ls -lth /dev_DSC2/
total 0
lrwxrwxrwx 1 dmdba dmdba 10 Aug 14 15:45 DMLOG -> /dev/DMLOG
lrwxrwxrwx 1 dmdba dmdba 9 Aug 14 15:40 VOTE -> /dev/VOTE
lrwxrwxrwx 1 dmdba dmdba 11 Aug 14 15:40 DMDATA -> /dev/DMDATA
lrwxrwxrwx 1 dmdba dmdba 8 Aug 14 15:40 DCR -> /dev/DCR
三、安装DM数据库软件
1、部署数据库软件
[root@node201 soft]# mount -o loop /soft/dm8_20240712_x86_rh7_64.iso /mnt
mount: /dev/loop0 is write-protected, mounting read-only
[dmdba@node201 mnt]$ ./DMInstall.bin -i
Installer Language:

3、创建和注册数据库服务
[root@node202 root]# pwd
/home/dmdba/dmdbms/script/root
[root@node201 root]# ./dm_service_installer.sh -t dmserver -p DMSERVER -dm_ini /home/dmdba/dmdbms/data/DAMENG/dm.ini
Created symlink from /etc/systemd/system/multi-user.target.wants/DmServiceDMSERVER.service to /usr/lib/systemd/system/DmServiceDMSERVER.service.

四、创建集群
1、创建ASM磁盘
如下所示，准备配置文件 DMDCR_CFG.INI 文件，保存到
node201的/home/dmdba/dmdsc/data/DSC01 下。
[root@node201 DSC01]# cat dmdcr_cfg.ini
DCR_N_GRP= 3
DCR_VTD_PATH=/dev_DSC2/VOTE
DCR_OGUID= 1071107589
[GRP]
DCR_GRP_TYPE = CSS
DCR_GRP_NAME = GRP_CSS
DCR_GRP_N_EP = 2
DCR_GRP_DSKCHK_CNT = 60
[GRP_CSS]
DCR_EP_NAME = CSS0
DCR_EP_HOST = 192.168.1.201
DCR_EP_PORT = 9836

3、配置dmasvrmal.ini
如下所示，准备 DMASM 的 MAL 配置文件 DMASVRMAL.INI，保存到 node201的/home/dmdba/dmdsc/data/DSC01 下
[root@node201 DSC01]# cat dmasvrmal.ini
[MAL_INST1]
MAL_INST_NAME= ASM0
MAL_HOST= 192.168.1.201
MAL_PORT= 4836
[MAL_INST2]
MAL_INST_NAME= ASM1
MAL_HOST= 192.168.1.202
MAL_PORT= 4837
如下所示，node202存储在/home/dmdba/dmdsc/data/DSC02目录下，内容和nde201一致：
[root@node202 DSC02]# cat dmasvrmal.ini
[MAL_INST1]
MAL_INST_NAME= ASM0
MAL_HOST= 192.168.1.201
MAL_PORT= 4836
[MAL_INST2]
MAL_INST_NAME= ASM1
MAL_HOST= 192.168.1.202
MAL_PORT= 4837
4、配置dmdcr.ini
如下所示，在node201下配置 dmdcr.ini文件：
[root@node201 DSC01]# cat dmdcr.ini
DMDCR_PATH = /dev_DSC2/DCR
DMDCR_MAL_PATH = /home/dmdba/dmdsc/data/DSC01/dmasvrmal.ini
DMDCR_SEQNO = 0
DMDCR_ASM_RESTART_INTERVAL = 0
DMDCR_ASM_STARTUP_CMD = /home/dmdba/dmdsc/bin/dmasmsvr dcr_ini=/home/dmdba/dmdsc/data/DSC01/dmdcr.ini
DMDCR_DB_RESTART_INTERVAL = 0
DMDCR_DB_STARTUP_CMD = /home/dmdba/dmdsc/bin/dmserver path=/home/dmdba/dmdsc/data/DSC01/DSC01_conf/dm.ini dcr_ini=/home/dmdba/dmdsc/data/DSC01/dmdcr.ini
DMDCR_LINK_CHECK_IP=192.168.1.100
设置了 DMDCR_LINK_CHECK_IP，须为 node201节点的 DMSERVER 和 DMASMSVR 赋予 ping 权限：
[root@node201 bin]# setcap cap_net_raw,cap_net_admin=eip /home/dmdba/dmdbms/bin/dmserver
[root@node201 bin]# setcap cap_net_raw,cap_net_admin=eip /home/dmdba/dmdbms/bin/dmasmsvr
如下所示，在node202下配置 dmdcr.ini文件：
[root@node202 DSC02]# cat dmdcr.ini
DMDCR_PATH = /dev_DSC2/DCR
DMDCR_MAL_PATH = /home/dmdba/dmdsc/data/DSC02/dmasvrmal.ini
DMDCR_SEQNO = 1
DMDCR_ASM_RESTART_INTERVAL = 0
DMDCR_ASM_STARTUP_CMD = /home/dmdba/dmdsc/bin/dmasmsvr dcr_ini=/home/dmdba/dmdsc/data/DSC02/dmdcr.ini
DMDCR_DB_RESTART_INTERVAL = 0
DMDCR_DB_STARTUP_CMD = /home/dmdba/dmdsc/bin/dmserver path=/home/dmdba/dmdsc/data/DSC02/DSC02_conf/dm.ini dcr_ini=/home/dmdba/dmdsc/data/DSC02/dmdcr.ini
DMDCR_LINK_CHECK_IP=192.168.1.100
设置了 DMDCR_LINK_CHECK_IP，须为 node202节点的 DMSERVER 和 DMASMSVR 赋予 ping 权限：
[root@node202 DSC02]# setcap cap_net_raw,cap_net_admin=eip /home/dmdba/dmdbms/bin/dmserver
[root@node202 DSC02]# setcap cap_net_raw,cap_net_admin=eip /home/dmdba/dmdbms/bin/dmasmsvr
5、启动 DMCSS、DMASM 服务程序（all nodes）
[root@node201 bin]# ./dmcss dcr_ini=/home/dmdba/dmdsc/data/DSC01/dmdcr.ini &
[1] 32553
[root@node202 bin]# ./dmcss dcr_ini=/home/dmdba/dmdsc/data/DSC02/dmdcr.ini &
[1] 27973
[root@node201 bin]# ./dmasmsvr dcr_ini=/home/dmdba/dmdsc/data/DSC01/dmdcr.ini &
[2] 1719
[root@node202 bin]# ./dmasmsvr dcr_ini=/home/dmdba/dmdsc/data/DSC02/dmdcr.ini &
[2] 28708
如下所示，集群通讯信息：
[2024-08-16 14:47:48:235] [ASM]: Set EP ASM0[0] as Control node

DMINIT 执行完成后，会在 config_path 目录（/home/dmdba/dmdsc/data/DSC01/DSC01_conf 和/home/dmdba/dmdsc/data/DSC02/DSC02_conf）下生成配置文件 DM.INI 和 DMMAL.INI。
将 node201上初始化库时产生的 DSC02 节点的配置文件（整个/home/dmdba/dmdsc/data/DSC02 文件夹）复制到 110 机器的/home/dmdba/dmdsc/data/DSC02/目录下。之后就可以启动数据库服务器了。
[root@node201 DSC02]# scp -r * node202:/home/dmdba/dmdsc/data/DSC02/

11、配置并启动 DMCSSM 监视器
DMCSSM 在任何机器上均可以启动，只要该台机器和 DMDSC 的真实机器网络是相通的，就可以监控 DMDSC 集群信息。
1）配置dmcssm.ini
[root@node201 DSC01]# cat dmcssm.ini
#和DMDCR_CFG.INI中的DCR_OGUID保持一致
CSSM_OGUID = 1071107589
#配置所有CSS的连接信息，
#与DMDCR_CFG.INI中CSS配置项的DCR_EP_HOST和DCR_EP_PORT保持一致
CSSM_CSS_IP = 192.168.1.201:9836
CSSM_CSS_IP = 192.168.1.202:9837
CSSM_LOG_PATH = /home/dmdba/dmdsc/data/cssm_log #监视器日志文件存放路径
CSSM_LOG_FILE_SIZE = 32 #每个日志文件最大32M
CSSM_LOG_SPACE_LIMIT = 0 #不限定日志文件总占用空间
启动 DMCSSM 集群监视器：
[root@node201 bin]# ./dmcssm ini_path=/home/dmdba/dmdsc/data/dmcssm.ini
[monitor] 2024-08-16 15:18:31: CSS MONITOR V8

[monitor] 2024-08-16 15:18:32: Wait CSS Control Node choosed succeed.
# DMCSSM 启动之后，可使用 show 命令在 DMCSSM 监视器中查看集群状态信息
