/dev/sdf /dev/raw/raw5 data disk2 10G
二、操作系统配置
1、关闭防火墙和 SELINUX
[root@cs ~]# service iptables stop
iptables: Setting chains to policy ACCEPT: nat mangle filter [ OK ]
iptables: Flushing firewall rules: [ OK ]
iptables: Unloading modules: [ OK ]
[root@cs ~]# chkconfig iptables off
[root@cs ~]# setenforce 0
[root@cs ~]# sed -i s:^SELINUX=.*$:SELINUX=disabled:g /etc/selinux/config
[root@cs ~]# service iptables stop
iptables: Setting chains to policy ACCEPT: nat mangle filter [ OK ]
iptables: Flushing firewall rules: [ OK ]
iptables: Unloading modules: [ OK ]
[root@cs ~]# chkconfig iptables off
[root@cs ~]# setenforce 0
[root@cs ~]# sed -i s:^SELINUX=.*$:SELINUX=disabled:g /etc/selinux/config2、修改主机名
[root@cs ~]# hostname dmrac1
[root@cs ~]# hostname dmrac2
[root@cs ~]# sed -i s:^HOSTNAME=.*$:HOSTNAME=dmrac1:g /etc/sysconfig/network
[root@cs ~]# sed -i s:^HOSTNAME=.*$:HOSTNAME=dmrac2:g /etc/sysconfig/network3、修改 hosts 文件
[root@cs ~]# echo
10.18.13.161 dmrac1
10.18.13.162 dmrac2 /etc/hosts
[root@cs ~]# echo
10.18.13.161 dmrac1
10.18.13.162 dmrac2 /etc/hosts三、安装达梦软件
为了减少对操作系统的影响，用户不应该以 root 系统用户来安装和运行 DM。用户可以在安装之前为 DM 创建一个专用的系统用户。具体操作详见
Oracle Linux 7.1 中安装达梦数据库 DM7
四、绑定 UDEV
[root@dmrac1 rules.d]# vi 99-dm-devices.rules

10737418240六、配置 dmdcr_cfg.ini 文件
在 2 个节点的 /dm7/data 目录下创建配置文件 dmdcr_cfg.ini，在文件中添加如下内容：
[root@dmrac1 /]# su - dmdba
[dmdba@dmrac1 ~]$ mkdir /dm7/data
[dmdba@dmrac1 ~]$cd /dm7/data
[dmdba@dmrac1 data]$ cat dmdcr_cfg.ini

[GRP_RAC]
DCR_EP_NAME = RAC1
DCR_EP_SEQNO = 1
DCR_EP_PORT = 5236
DCR_CHECK_PORT = 9742七、使用 DMASMCMD 工具初始化（任意一节点执行）
[dmdba@dmrac1 data]$ dmasmcmd
DMASMCMD V7.1.6.46-Build(2018.02.08-89107)ENT
ASM create dcrdisk /dev/raw/raw1 dcr

[Trace]DG 125 allocate 4 extents for file 0xfd000002.
Used time: 36.305(ms).八、准备 DMASM 的 MAL 配置文件
在 2 个节点的 /dm7/data 目录下创建 DMASM 的 MAL 配置文件（命名为 dmasvrmal.ini），使用 DMASM 的所有节点都要配置，内容完全一样。
[dmdba@dmrac1 data]$ vi dmasvrmal.ini
[MAL_INST1]
MAL_INST_NAME = ASM0
MAL_HOST = 10.10.10.161
MAL_PORT = 7236
[MAL_INST2]
MAL_INST_NAME = ASM1
MAL_HOST = 10.10.10.162
MAL_PORT = 7237
[dmdba@dmrac2 data]$ vi dmasvrmal.ini
[MAL_INST1]
MAL_INST_NAME = ASM0
MAL_HOST = 10.10.10.161
MAL_PORT = 7236
[MAL_INST2]
MAL_INST_NAME = ASM1
MAL_HOST = 10.10.10.162
MAL_PORT = 7237
~九、准备 dmdcr.ini 配置文件
dmdcr.ini 是 dmcss、dmasmsvr、dmasmtool 工具的输入参数。记录了当前节点序列号以及 DCR 磁盘路径。
在 2 个节点的 /dm/dmdbms/data 目录下创建 dmdcr.ini 配置文件，dmdcr_path 相同，dmasvrmal.ini 文件内容也相同，dmdcr_seqo 分别为 0 和 1。
节点 1：
[dmdba@dmrac1 data]$ vi dmdcr.ini
DMDCR_PATH = /dev/raw/raw1
DMDCR_MAL_PATH =/dm7/data/dmasvrmal.ini
DMDCR_SEQNO = 0
DMDCR_ASM_RESTART_INTERVAL = 0
DMDCR_ASM_STARTUP_CMD = /dm7/bin/dmasmsvr dcr_ini=/dm7/data/dmdcr.ini
DMDCR_DB_RESTART_INTERVAL = 0
DMDCR_DB_STARTUP_CMD = /dm7/bin/dmserver path=/dm7/data/rac0_config/dm.ini dcr_ini=/dm7/data/dmdcr.ini节点 2:
[dmdba@dmrac2 data]$ vi dmdcr.ini
DMDCR_PATH = /dev/raw/raw1
DMDCR_MAL_PATH =/dm7/data/dmasvrmal.ini
DMDCR_SEQNO = 1
DMDCR_ASM_RESTART_INTERVAL = 0
DMDCR_ASM_STARTUP_CMD = /dm7/bin/dmasmsvr dcr_ini=/dm7/data/dmdcr.ini
DMDCR_DB_RESTART_INTERVAL = 0
DMDCR_DB_STARTUP_CMD = /dm7/bin/dmserver path=/dm7/data/rac1_config/dm.ini dcr_ini=/dm7/data/dmdcr.ini十、启动 DMCSS、DMASM 服务程序
1、注册 DMCSS 和 DMASM 服务
节点一:
[root@dmrac1 ~]# /dm7/script/root/dm_service_installer.sh -t dmcss -i /dm7/data/dmdcr.ini -p rac1
Move the service script file(/dm7/bin/DmCSSServicerac1 to /etc/rc.d/init.d/DmCSSServicerac1)
Finished to create the service (DmCSSServicerac1)
[root@dmrac1 ~]# /dm7/script/root/dm_service_installer.sh -t dmasmsvr -i /dm7/data/dmdcr.ini -p rac1
Move the service script file(/dm7/bin/DmASMSvrServicerac1 to /etc/rc.d/init.d/DmASMSvrServicerac1)
Finished to create the service (DmASMSvrServicerac1)
[root@dmrac1 ~]#节点二:
[root@dmrac2 ~]# /dm7/script/root/dm_service_installer.sh -t dmcss -i /dm7/data/dmdcr.ini -p rac2
Move the service script file(/dm7/bin/DmCSSServicerac2 to /etc/rc.d/init.d/DmCSSServicerac2)
Finished to create the service (DmCSSServicerac2)
[root@dmrac2 ~]# /dm7/script/root/dm_service_installer.sh -t dmasmsvr -i /dm7/data/dmdcr.ini -p rac2
Move the service script file(/dm7/bin/DmASMSvrServicerac2 to /etc/rc.d/init.d/DmASMSvrServicerac2)
Finished to create the service (DmASMSvrServicerac2)2、启动 DMCSS 和 DMASM 服务
节点一：
[root@dmrac1 init.d]# service DmCSSServicerac1 start
Starting DmCSSServicerac1: [ OK ]
[root@dmrac1 init.d]# service DmASMSvrServicerac1 start
Starting DmASMSvrServicerac1: [ OK ]节点二：
[root@dmrac2 init.d]# service DmCSSServicerac2 start
Starting DmCSSServicerac2: [ OK ]
[root@dmrac2 init.d]# service DmASMSvrServicerac2 start
Starting DmASMSvrServicerac2: [ OK ]十一、创建 DMASM 磁盘组
在任意节点使用 dmasmtool 工具创建 DMASM 磁盘组。
[dmdba@dmrac1 ~]$ dmasmtool DCR_INI=/dm7/data/dmdcr.ini
DMASMTOOL V7.1.6.46-Build(2018.02.08-89107)ENT
ASM create diskgroup DMLOG asmdisk /dev/raw/raw3
Used time: 00:00:06.363.
ASM create diskgroup DMDATA asmdisk /dev/raw/raw4
Used time: 00:00:06.504.十二、准备 dminit.ini 配置文件
在 2 个节点的 /dm/dmdbms/data 目录下创建 dminit.ini 配置文件，添加如下内容。在 2 个节点都创建。
[dmdba@dmrac1 data]$ vi dminit.ini
db_name = rac
system_path = +DMDATA/data
system = +DMDATA/data/rac/system.dbf
system_size = 128
roll = +DMDATA/data/rac/roll.dbf
roll_size = 128
main = +DMDATA/data/rac/main.dbf
main_size = 128
ctl_path = +DMDATA/data/rac/dm.ctl
ctl_size = 8
log_size = 256
dcr_path = /dev/raw/raw1 #dcr 磁盘路径，目前不支持 asm，只能是裸设备
dcr_seqno = 0
auto_overwrite = 1
[RAC0] #inst_name 跟 dmdcr_cfg.ini 中 DB 类型 group 中 DCR_EP_NAME 对应
config_path = /dm7/data/rac0_config
port_num = 5236
mal_host = 10.10.10.161
mal_port = 9340
log_path = +DMLOG/log/rac0_log01.log
log_path = +DMLOG/log/rac0_log02.log
[RAC1] #inst_name 跟 dmdcr_cfg.ini 中 DB 类型 group 中 DCR_EP_NAME 对应
config_path = /dm7/data/rac1_config
port_num = 5236
mal_host = 10.10.10.162
mal_port = 9341
log_path = +DMLOG/log/rac1_log01.log
log_path = +DMLOG/log/rac1_log02.log
[dmdba@dmrac2 data]$ vi dminit.ini
db_name = rac
system_path = +DMDATA/data
system = +DMDATA/data/rac/system.dbf
system_size = 128
roll = +DMDATA/data/rac/roll.dbf
roll_size = 128
main = +DMDATA/data/rac/main.dbf
main_size = 128
ctl_path = +DMDATA/data/rac/dm.ctl
ctl_size = 8
log_size = 256
dcr_path = /dev/raw/raw1 #dcr 磁盘路径，目前不支持 asm，只能是裸设备
dcr_seqno = 0
auto_overwrite = 1
[RAC0] #inst_name 跟 dmdcr_cfg.ini 中 DB 类型 group 中 DCR_EP_NAME 对应
config_path = /dm7/data/rac0_config
port_num = 5236
mal_host = 10.10.10.161
mal_port = 9340
log_path = +DMLOG/log/rac0_log01.log
log_path = +DMLOG/log/rac0_log02.log
[RAC1] #inst_name 跟 dmdcr_cfg.ini 中 DB 类型 group 中 DCR_EP_NAME 对应
config_path = /dm7/data/rac1_config
port_num = 5236
mal_host = 10.10.10.162
mal_port = 9341
log_path = +DMLOG/log/rac1_log01.log
log_path = +DMLOG/log/rac1_log02.log十三、使用 dminit 初始化数据库
在任意节点启动 dminit 工具初始化数据库。dminit 执行完成后，会在 config_path 目录（/dm7/data/rac0_config 和 /dm7/data/rac1_config）下生成配置文件 dm.ini 和 dmmal.ini。
[dmdba@dmrac1 data]$ dminit control=/dm7/data/dminit.ini
initdb V7.1.6.46-Build(2018.02.08-89107)ENT
db version: 0x7000a
file dm.key not found, use default license!
License will expire on 2020-05-08
log file path: +DMLOG/log/rac0_log01.log
log file path: +DMLOG/log/rac0_log02.log
log file path: +DMLOG/log/rac1_log01.log
log file path: +DMLOG/log/rac1_log02.log
write to dir [+DMDATA/data/rac].
create dm database success. 2020-04-24 16:39:03将节点一的配置文件复制到节点二：
[dmdba@dmrac1 data]$ scp -r rac1_config 10.18.13.162:`pwd`
The authenticity of host 10.18.13.162 (10.18.13.162) can t be established.

dmmal.ini 100% 204 0.2KB/s 00:00
[dmdba@dmrac1 data]$十四、启动数据库服务器
1、在 2 个节点分别注册 DM 数据库服务：
节点一：
[root@dmrac1 init.d]# /dm7/script/root/dm_service_installer.sh -t dmserver -i /dm7/data/rac0_config/dm.ini -d /dm7/data/dmdcr.ini -p rac1
Move the service script file(/dm7/bin/DmServicerac1 to /etc/rc.d/init.d/DmServicerac1)
Finished to create the service (DmServicerac1)节点二：
[root@dmrac2 ~]# /dm7/script/root/dm_service_installer.sh -t dmserver -i /dm7/data/rac1_config/dm.ini -d /dm7/data/dmdcr.ini -p rac2
Move the service script file(/dm7/bin/DmServicerac2 to /etc/rc.d/init.d/DmServicerac2)
Finished to create the service (DmServicerac2)2、启动数据库
[root@dmrac1 init.d]# service DmServicerac1 start
Starting DmServicerac1: [ OK ]
[root@dmrac2 ~]# service DmServicerac2 start
Starting DmServicerac2: [ OK ]手工启动命令如下，手工启动后窗口不能关闭，所以
./dmserver /dm7/data/rac0_config/dm.ini dcr_ini=/dm7/data/dmdcr.ini
./dmserver /dm7/data/rac1_config/dm.ini dcr_ini=/dm7/data/dmdcr.ini15 连接数据库验证
