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/config
2、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/network
3、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 ACTION=="add", KERNEL=="sdb", RUN+="/bin/raw /dev/raw/raw1 %N" ACTION=="add", KERNEL=="sdc", RUN+="/bin/raw /dev/raw/raw2 %N" ACTION=="add", KERNEL=="sdd", RUN+="/bin/raw /dev/raw/raw3 %N" ACTION=="add", KERNEL=="sde", RUN+="/bin/raw /dev/raw/raw4 %N" ACTION=="add", KERNEL=="sdf", RUN+="/bin/raw /dev/raw/raw5 %N" ACTION=="add", KERNEL=="raw[1-5]", OWNER="dmdba", GROUP="dinstall", MODE="660" ~ [root@dmrac1 rules.d]# start_udev Starting udev: [ OK ] [root@dmrac1 rules.d]# ls -lrt /dev/raw/ total 0 crw-rw----. 1 root disk 162, 0 Apr 24 14:08 rawctl crw-rw----. 1 dmdba dinstall 162, 2 Apr 24 14:08 raw2 crw-rw----. 1 dmdba dinstall 162, 1 Apr 24 14:08 raw1 crw-rw----. 1 dmdba dinstall 162, 4 Apr 24 14:08 raw4 crw-rw----. 1 dmdba dinstall 162, 3 Apr 24 14:08 raw3 crw-rw----. 1 dmdba dinstall 162, 5 Apr 24 14:08 raw5 [root@dmrac2 rules.d]# vi 99-dm-devices.rules ACTION=="add", KERNEL=="sdb", RUN+="/bin/raw /dev/raw/raw1 %N" ACTION=="add", KERNEL=="sdc", RUN+="/bin/raw /dev/raw/raw2 %N" ACTION=="add", KERNEL=="sdd", RUN+="/bin/raw /dev/raw/raw3 %N" ACTION=="add", KERNEL=="sde", RUN+="/bin/raw /dev/raw/raw4 %N" ACTION=="add", KERNEL=="sdf", RUN+="/bin/raw /dev/raw/raw5 %N" ACTION=="add", KERNEL=="raw[1-5]", OWNER="dmdba", GROUP="dinstall", MODE="660" ~ [root@dmrac2 rules.d]# start_udev Starting udev: [ OK ] [root@dmrac2 rules.d]# ls -lrt /dev/raw/ total 0 crw-rw----. 1 root disk 162, 0 Apr 24 14:08 rawctl crw-rw----. 1 dmdba dinstall 162, 2 Apr 24 14:08 raw2 crw-rw----. 1 dmdba dinstall 162, 1 Apr 24 14:08 raw1 crw-rw----. 1 dmdba dinstall 162, 4 Apr 24 14:08 raw4 crw-rw----. 1 dmdba dinstall 162, 3 Apr 24 14:08 raw3 crw-rw----. 1 dmdba dinstall 162, 5 Apr 24 14:08 raw5
可以通过blockdev –getsize64 /dev/raw/raw1命令查看裸设备大小
[root@dmrac1 rules.d]# blockdev --getsize64 /dev/raw/raw1 2147483648 [root@dmrac1 rules.d]# blockdev --getsize64 /dev/raw/raw2 2147483648 [root@dmrac1 rules.d]# blockdev --getsize64 /dev/raw/raw3 10737418240 [root@dmrac1 rules.d]# blockdev --getsize64 /dev/raw/raw4 10737418240 [root@dmrac1 rules.d]# blockdev --getsize64 /dev/raw/raw5 10737418240 [root@dmrac2 rules.d]# blockdev --getsize64 /dev/raw/raw1 2147483648 [root@dmrac2 rules.d]# blockdev --getsize64 /dev/raw/raw2 2147483648 [root@dmrac2 rules.d]# blockdev --getsize64 /dev/raw/raw3 10737418240 [root@dmrac2 rules.d]# blockdev --getsize64 /dev/raw/raw4 10737418240 [root@dmrac2 rules.d]# blockdev --getsize64 /dev/raw/raw5 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 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 = 10.10.10.161 DCR_EP_PORT = 9541 [GRP_CSS] DCR_EP_NAME = CSS1 DCR_EP_HOST = 10.10.10.162 DCR_EP_PORT = 9542 [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 = 10 DCR_EP_HOST = 10.18.13.161 DCR_EP_PORT = 9641 DCR_EP_ASM_LOAD_PATH = /dev/raw [GRP_ASM] DCR_EP_NAME = ASM1 DCR_EP_SHM_KEY = 93361 DCR_EP_SHM_SIZE = 10 DCR_EP_HOST = 10.18.13.162 DCR_EP_PORT = 9642 DCR_EP_ASM_LOAD_PATH = /dev/raw [GRP] DCR_GRP_TYPE = DB DCR_GRP_NAME = GRP_RAC DCR_GRP_N_EP = 2 DCR_GRP_DSKCHK_CNT = 60 [GRP_RAC] DCR_EP_NAME = RAC0 DCR_EP_SEQNO = 0 DCR_EP_PORT = 5236 DCR_CHECK_PORT = 9741 [GRP_RAC] DCR_EP_NAME = RAC1 DCR_EP_SEQNO = 1 DCR_EP_PORT = 5236 DCR_CHECK_PORT = 9742 [root@dmrac2 /]# su - dmdba [dmdba@dmrac2 ~]$ mkdir /dm7/data [dmdba@dmrac2 ~]$cd /dm7/data [dmdba@dmrac2 data]$ cat 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 = 10.10.10.161 DCR_EP_PORT = 9541 [GRP_CSS] DCR_EP_NAME = CSS1 DCR_EP_HOST = 10.10.10.162 DCR_EP_PORT = 9542 [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 = 10 DCR_EP_HOST = 10.18.13.161 DCR_EP_PORT = 9641 DCR_EP_ASM_LOAD_PATH = /dev/raw [GRP_ASM] DCR_EP_NAME = ASM1 DCR_EP_SHM_KEY = 93361 DCR_EP_SHM_SIZE = 10 DCR_EP_HOST = 10.18.13.162 DCR_EP_PORT = 9642 DCR_EP_ASM_LOAD_PATH = /dev/raw [GRP] DCR_GRP_TYPE = DB DCR_GRP_NAME = GRP_RAC DCR_GRP_N_EP = 2 DCR_GRP_DSKCHK_CNT = 60 [GRP_RAC] DCR_EP_NAME = RAC0 DCR_EP_SEQNO = 0 DCR_EP_PORT = 5236 DCR_CHECK_PORT = 9741 [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' the ASM initialize dcrdisk /dev/raw/raw1 to name DMASMdcr Used time: 9.322(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 #ASM DMDCR_ASM_RESTART_INTERVAL = 0 DMDCR_ASM_STARTUP_CMD = /dm7/bin/dmasmsvr dcr_ini=/dm7/data/dmdcr.ini #DB 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 #ASM DMDCR_ASM_RESTART_INTERVAL = 0 DMDCR_ASM_STARTUP_CMD = /dm7/bin/dmasmsvr dcr_ini=/dm7/data/dmdcr.ini #DB 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. RSA key fingerprint is 89:fc:3e:e3:2d:27:94:07:0e:6b:fc:c5:e8:89:44:1f. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '10.18.13.162' (RSA) to the list of known hosts. dmdba@10.18.13.162's password: sqllog.ini 100% 479 0.5KB/s 00:00 dm.ini 100% 40KB 39.8KB/s 00:00 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.ini
15 连接数据库验证
15.1 配置服务名文件
[dmdba@dmrac1 ~]$ vi /etc/dm_svc.conf TIME_ZONE=(480) rac=(10.18.13.161:5236,10.18.13.162:5236) SWITCH_TIME=(10000) SWITCH_INTERVAL=(10) TIME_ZONE=(480) LANGUAGE=(en) [dmdba@dmrac2 ~]$ vi /etc/dm_svc.conf TIME_ZONE=(480) rac=(10.18.13.161:5236,10.18.13.162:5236) SWITCH_TIME=(10000) SWITCH_INTERVAL=(10) TIME_ZONE=(480) LANGUAGE=(en)
