DM8_DSC集群部署

作者:互联网

一、准备两台服务器 192.168.0.89 192.168.0.76 二、两节点进行数据库安装 1)创建dmdba用户和安装组dinstall 2)修改最大文件打开数 ulimit -n 65536 3)数据库安装目录:/home/dmdba/dmdbms 三、裸设备绑定 1)新增一块共享磁盘20G 2)对该磁盘分区,大小为200M,200M,4G,剩余全部;

3)绑定裸设备 vi /etc/udev/rules.d/90-raw.rules ACTION=="add",KERNEL=="sdb1",RUN+="/bin/raw /dev/raw/raw1 %N" ACTION=="add",KERNEL=="sdb2",RUN+="/bin/raw /dev/raw/raw2 %N" ACTION=="add",KERNEL=="sdb3",RUN+="/bin/raw /dev/raw/raw3 %N" ACTION=="add",KERNEL=="sdb4",RUN+="/bin/raw /dev/raw/raw4 %N" KERNEL=="raw[1-4]", OWNER="dmdba", GROUP="dinstall", MODE="660" 4) 执行以下命令,使 udev 生效 udevadm trigger --type=devices --action=change ll /dev/raw/raw* #查看是否生效,没有生效重新启动再次查看; 四、参数文件配置 1)配置dmdcr_cfg.ini 配置文件放到/home/dmdba/data 目录(89节点) DCR_N_GRP = 3 DCR_VTD_PATH = /dev/raw/raw2 DCR_OGUID = 63635 [GRP] DCR_GRP_TYPE = CSS DCR_GRP_NAME = CSS DCR_GRP_N_EP = 2 DCR_GRP_DSKCHK_CNT = 60 [CSS] DCR_EP_NAME = CSS1 DCR_EP_HOST = 192.168.0.89 DCR_EP_PORT = 9341 [CSS] DCR_EP_NAME = CSS2 DCR_EP_HOST = 192.168.0.76 DCR_EP_PORT = 9341   [GRP] DCR_GRP_TYPE = ASM DCR_GRP_NAME = ASM DCR_GRP_N_EP = 2 DCR_GRP_DSKCHK_CNT = 60 [ASM] DCR_EP_NAME = ASM1 DCR_EP_SHM_KEY = 93360 DCR_EP_SHM_SIZE = 10 DCR_EP_HOST = 192.168.0.89 DCR_EP_PORT = 9351 DCR_EP_ASM_LOAD_PATH = /dev/raw [ASM] DCR_EP_NAME = ASM2 DCR_EP_SHM_KEY = 93361 DCR_EP_SHM_SIZE = 10 DCR_EP_HOST = 192.168.0.76 DCR_EP_PORT = 9351 DCR_EP_ASM_LOAD_PATH = /dev/raw   [GRP] DCR_GRP_TYPE = DB DCR_GRP_NAME = DSC 2)使用 DMASMCMD 工具初始化(89节点) ./dmasmcmd(在安装目录的bin目录下) create dcrdisk '/dev/raw/raw1' 'dcr' create votedisk '/dev/raw/raw2' 'vote' create asmdisk '/dev/raw/raw3' 'LOG0' create asmdisk '/dev/raw/raw4' 'DATA0' init dcrdisk '/dev/raw/raw1' from '/home/dmdba/data/dmdcr_cfg.ini' identified by 'abcd' init votedisk '/dev/raw/raw2' from '/home/dmdba/data/dmdcr_cfg.ini' 3)准备 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,保存到/home/dmdba/data 目录下 [MAL_INST1] MAL_INST_NAME = ASM1 MAL_HOST = 192.168.0.89 MAL_PORT = 7236 [MAL_INST2] MAL_INST_NAME = ASM2 MAL_HOST = 192.168.0.76 MAL_PORT = 7237 4)准备 dmdcr.ini 配置文件,保存到/home/dmdba/data 目录下面 DMDCR_PATH = /dev/raw/raw1 DMDCR_MAL_PATH =/home/dmdba/data/dmasvrmal.ini #dmasmsvr 使用的 MAL 配置文件路径 DMDCR_SEQNO = 0 #ASM 重启参数,命令行方式启动 DMDCR_ASM_RESTART_INTERVAL = 0 DMDCR_ASM_STARTUP_CMD = /home/dmdba/dmdbms/bin/dmasmsvr dcr_ini=/home/dmdba/data/dmdcr.ini #DB 重启参数,命令行方式启动 DMDCR_DB_RESTART_INTERVAL = 0 DMDCR_DB_STARTUP_CMD = /home/dmdba/dmdbms/bin/dmserver path=/home/dmdba/data/dsc0_config/dm.ini dcr_ini=/home/dmdba/data/dmdcr.ini 5)发送dmasvrmal.ini,dmdcr.ini到另一个节点,并修改相应参数; 在另一节点修改dmdcr.ini的DMDCR_SEQNO = 1即可

五、初始化两节点实例 1)两节点分别启动 DMCSS、DMASM 服务程序 ./dmcss DCR_INI=/home/data/dmdcr.ini ./dmasmsvr DCR_INI=/home/data/dmdcr.ini 2)启动后不要退出,复制会话在89节点使用 dmasmtool 工具创建 DMASM 磁盘组 ./dmasmtool DCR_INI=/home/data/dmdcr.ini #创建日志磁盘组 create diskgroup ‘DMLOG’ asmdisk ‘/dev/raw/raw3’ #创建数据磁盘组 create diskgroup ‘DMDATA’ asmdisk ‘/dev/raw/raw4’ 3)准备 dminit.ini 配置文件,保存到/home/dmdba/data 目录(初始化库) db_name = DSC system_path = +DMDATA/data   system = +DMDATA/data/dsc/system.dbf system_size = 128 roll = +DMDATA/data/dsc/roll.dbf roll_size = 128 main = +DMDATA/data/dsc/main.dbf main_size = 128 ctl_path = +DMDATA/data/dsc/dm.ctl ctl_size = 8 log_size = 100 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 [DSC1] #inst_name 跟 dmdcr_cfg.ini 中 DB 类型 group 中 DCR_EP_NAME 对应 config_path = /home/dmdba/data/dsc1 port_num = 5236 mal_host = 192.168.0.89 mal_port = 9236 log_path = +DMLOG/log/DSC1_log01.log log_path = +DMLOG/log/DSC1_log02.log [DSC2] #inst_name 跟 dmdcr_cfg.ini 中 DB 类型 group 中 DCR_EP_NAME 对应 config_path = /home/dmdba/data/dsc2 port_num = 5236 mal_host = 192.168.0.76 mal_port = 9236 log_path = +DMLOG/log/DSC2_log01.log log_path = +DMLOG/log/DSC2_log02.log 4)./dminit control=/home/dmdba/data/dminit.ini

dsc2目录拷贝到76节点的/home/dmdba/data目录下 scp -r dsc2 196.168.0.76:/home/dmdba/data 5)启动数据库服务:(两节点都需要启动) ./dmserver /home/dmdba/data/dsc1/dm.ini dcr_ini=/home/dmdba/data/dmdcr.ini 6)登录disql,查询select * from V$dsc_ep_info;可以查看到两个节点

7)注册服务(每个节点注册三个服务) 在安装目录的script/root下执行注册服务的脚本 ./dm_service_installer.sh -t dmcss -dcr_ini /home/dmdba/data/dmdcr.ini -p DM1   ./dm_service_installer.sh -t dmasmsvr -p DM1 -dcr_ini /home/dmdba/data/dmdcr.ini -y DmCSSServiceDM1.service   ./dm_service_installer.sh -t dmserver -dcr_ini /home/dmdba/data/dmdcr.ini -dm_ini /home/dmdba/data/dsc1/dm.ini -p DM1 -y DmASMSvrServiceDM1.service 8)**生产环境还需要设置归档和备份**
