dmsrv02 192.168.18.72(内部)、192.168.20.72(业务) CSS1、ADM1、DSC1 Kylin Linux Advanced Server release V10 (Sword)

2、磁盘环境

测试环境使用starwind软件来管理iscsi共享盘。

裸设备路径 用途 大小 ASM盘名称
/dev/raw/raw1 DCR磁盘 2GB dcr
/dev/raw/raw2 VOTE磁盘 2GB vote
/dev/raw/raw3 数据文件 50GB data
/dev/raw/raw4 日志文件 20GB log

二、主机磁盘配置

安装达梦8数据库软件。

1、target服务端配置磁盘

一共在target服务端配置4块磁盘。

节点1使用udev固定盘名称

节点2使用udev固定盘名称

218f0ca5506ebe813
[root@dmsrv02 ~]# /usr/lib/udev/scsi_id -g -u /dev/sdb

三、基础环境搭建

1、初始化磁盘

节点1、2配置配置文件

[dmdba@dmsrv02 ~]$ cat /dm8/config/dmdcr_cfg.ini
DCR_N_GRP = 3
DCR_VTD_PATH = /dev/raw/raw2
DCR_OGUID = 63635
[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 = 192.168.18.71
DCR_EP_PORT = 9341
[GRP_CSS]
DCR_EP_NAME = CSS1
DCR_EP_HOST = 192.168.18.72
DCR_EP_PORT = 9343
[GRP]
DCR_GRP_TYPE = ASM
DCR_GRP_NAME = GRP_ASM
DCR_GRP_N_EP = 2
DCR_GRP_DSKCHK_CNT = 60
[GRP_ASM]
DCR_EP_NAME = ASM0
DCR_EP_SHM_KEY = 93360
DCR_EP_SHM_SIZE = 20
DCR_EP_HOST = 192.168.18.71
DCR_EP_PORT = 9349
DCR_EP_ASM_LOAD_PATH = /dev/raw
[GRP_ASM]
DCR_EP_NAME = ASM1
DCR_EP_SHM_KEY = 93361
DCR_EP_SHM_SIZE = 20
DCR_EP_HOST = 192.168.18.72
DCR_EP_PORT = 9351
DCR_EP_ASM_LOAD_PATH = /dev/raw
[GRP]
DCR_GRP_TYPE = DB
DCR_GRP_NAME = GRP_DSC
DCR_GRP_N_EP = 2
DCR_GRP_DSKCHK_CNT = 60
[GRP_DSC]
DCR_EP_NAME = DSC0
DCR_EP_SEQNO = 0
DCR_EP_PORT = 5236
DCR_CHECK_PORT = 9741
[GRP_DSC]
DCR_EP_NAME = DSC1
DCR_EP_SEQNO = 1
DCR_EP_PORT = 5237
DCR_CHECK_PORT = 9742

主机1配置asm盘

[dmdba@dmsrv02 bin]$ ./dmasmcmd
dmasmcmd V8
ASM>create dcrdisk '/dev/raw/raw1' 'dcr'
[TRACE]The ASM initialize dcrdisk /dev/raw/raw1 to name DMASMdcr

[TRACE]DG 125 alloc 4 extents for 0xfd000002 (0, 0, 2)->(0, 0, 5)
Used time: 156.644(ms).

2、准备dmasvrmal.ini

[dmdba@dmsrv01 config]$ cat /dm8/config/dmasvrmal.ini
[MAL_INST1]
 MAL_INST_NAME = ASM0
 MAL_HOST = 192.168.18.71
 MAL_PORT = 7236
[MAL_INST2]
 MAL_INST_NAME = ASM1
 MAL_HOST = 192.168.18.72
 MAL_PORT = 7236

3、准备dmdcr.ini

节点1

[dmdba@dmsrv01 config]$ cat /dm8/config/dmdcr.ini
DMDCR_PATH = /dev/raw/raw1
DMDCR_MAL_PATH =/dm8/config/dmasvrmal.ini
DMDCR_SEQNO = 0
DMDCR_ASM_RESTART_INTERVAL = 10
DMDCR_ASM_STARTUP_CMD = /dm8/bin/dmasmsvr dcr_ini=/dm8/config/dmdcr.ini
DMDCR_DB_RESTART_INTERVAL = 30
DMDCR_DB_STARTUP_CMD = /dm8/bin/dmserver path=/dm8/config/dsc1/dm.ini dcr_ini=/dm8/config/dmdcr.ini

节点2

[dmdba@dmsrv02 bin]$ cat /dm8/config/dmdcr.ini
DMDCR_PATH = /dev/raw/raw1
DMDCR_MAL_PATH =/dm8/config/dmasvrmal.ini
DMDCR_SEQNO = 1
DMDCR_ASM_RESTART_INTERVAL = 10
DMDCR_ASM_STARTUP_CMD = /dm8/bin/dmasmsvr dcr_ini=/dm8/config/dmdcr.ini
DMDCR_DB_RESTART_INTERVAL = 30
DMDCR_DB_STARTUP_CMD = /dm8/bin/dmserver path=/dm8/config/dsc2/dm.ini dcr_ini=/dm8/config/dmdcr.ini

4、启动DMCSS服务

两节点执行

 ./dmcss DCR_INI=/dm8/config/dmdcr.ini

5、启动DMASM服务

./dmasmsvr DCR_INI=/dm8/config/dmdcr.ini

dmcss会自动拉起dmasmsvr，以上命令可能会执行失败

[dmdba@dmsrv01 bin]$ ps -ef|grep dmasm
dmdba       2430       1  0 23:12 ?        00:00:00 /dm8/bin/dmasmsvr dcr_ini=/dm8/config/dmdcr.ini
dmdba       2654    2562  0 23:18 pts/1    00:00:00 grep dmasm
[dmdba@dmsrv01 bin]$ ps -ef|grep dmcss
dmdba       2405    2271  0 23:12 pts/0    00:00:00 ./dmcss DCR_INI=/dm8/config/dmdcr.ini
dmdba       2659    2562  0 23:19 pts/1    00:00:00 grep dmcss

6、创建磁盘组

[dmdba@dmsrv01 bin]$ ./dmasmtool DCR_INI=/dm8/config/dmdcr.ini
DMASMTOOL V8
ASM>create diskgroup 'DATA' asmdisk '/dev/raw/raw3'
Used time: 103.367(ms).
ASM>create diskgroup 'LOG' asmdisk '/dev/raw/raw4'
Used time: 114.902(ms).

四、数据库创建

1、配置初始化文件

[dmdba@dmsrv01 ~]$ cat /dm8/config/dminit.ini
db_name = dsc
system_path = +DATA/data
system = +DATA/data/dsc/system.dbf
system_size = 128
roll = +DATA/data/dsc/roll.dbf
roll_size = 128
main = +DATA/data/dsc/main.dbf
main_size = 128
ctl_path = +DATA/data/dsc/dm.ctl
ctl_size = 8
log_size = 256
dcr_path = /dev/raw/raw1
dcr_seqno = 0
auto_overwrite = 1
[DSC0]
config_path = /dm8/config/dsc1
port_num = 5236
mal_host = 192.168.18.71
mal_port = 9340
log_path = +LOG/log/dsc0_log01.log
log_path = +LOG/log/dsc0_log02.log
[DSC1]
config_path = /dm8/config/dsc2
port_num = 5237
mal_host = 192.168.18.72
mal_port = 9341
log_path = +LOG/log/dsc1_log01.log
log_path = +LOG/log/dsc1_log02.log

2、节点1初始化数据库

[dmdba@dmsrv01 ~]$ mkdir -p /dm8/config/dsc1
[dmdba@dmsrv01 ~]$ mkdir -p /dm8/config/dsc2
[dmdba@dmsrv01 ~]$ cd /dm8/bin
[dmdba@dmsrv01 bin]$ ./dminit control=/dm8/config/dminit.ini
initdb V8

Normal of FAST

 log file path: +LOG/log/dsc0_log01.log


 log file path: +LOG/log/dsc0_log02.log


 log file path: +LOG/log/dsc1_log01.log


 log file path: +LOG/log/dsc1_log02.log

write to dir [+DATA/data/dsc].
create dm database success. 2025-05-27 23:31:46

3、拷贝配置文件，查看两节点数据库进程

节点1复制配置文件到节点2

[dmdba@dmsrv01 bin]$ scp /dm8/config/dsc
/dm8/config/dsc1/  /dm8/config/dsc2/
[dmdba@dmsrv01 bin]$ scp -r /dm8/config/dsc2 192.168.18.72:/dm8/config/

[dmdba@dmsrv01 bin]$

节点1 css服务可以查看数据库状态

节点2 css服务可以查看数据库状态

4、配置监视器

在节点2配置监视器

[dmdba@dmsrv01 bin]$ cat /dm8/config/dmcssm.ini
CSSM_OGUID = 63635
CSSM_CSS_IP = 192.168.18.71:9341
CSSM_CSS_IP = 192.168.18.72:9343
CSSM_LOG_PATH = /dm8/cssm_log
CSSM_LOG_FILE_SIZE = 32
CSSM_LOG_SPACE_LIMIT = 0
[dmdba@dmsrv01 bin]$ ./dmcssm ini_path=/dm8/config/dmcssm.ini
[monitor]          [2025-05-27 23:43:26:966] CSS MONITOR V8
