[INFO] Installed DM DBMS completely.
Please execute the commands by root:
/d08/dmdbms/script/root/root_installer.sh
End
root下执行/d08/dmdbms/script/root/root_installer.sh
会创建APservice服务并启动服务
8.dminit建库
[dmdba@ocp ~]$ dminit
initdb V8.1.0.147-Build(2019.03.27-104581)ENT
db version: 0x7000a
file dm.key not found, use default license!
License will expire on 2020-03-27
input system dir: /d08/dmdbms/data —数据库文件存放目录
input db name: dmnew —数据库名称
input port num: 5010 —端口
input page size(4, 8, 16, 32): 8 —页大小
input extent size(16, 32): 16 —簇大小
input time zone(-12:59,+14:00): +8 —时区
string case sensitive? ([Y]es, [N]o): Y —启用大小写敏感
which charset to use? (0[GB18030], 1[UTF-8], 2[EUC-KR]): 1 —字符集
length in char? ([Y]es, [N]o): Y —VARCHAR类型对象的长度是否以字符 为单位
enable database encrypt? ([Y]es, [N]o): N —不启用数据库加密
page check mode? (0/1/2): 0 —页检查
input elog path: /d08/dmdbms/log —服务日志路径
auto_overwrite mode? (0/1/2): 1 —日志文件是否覆盖 1是有重名的则覆盖，0是不覆盖，2是清空目录
log file path: /d08/dmdbms/data/dmnew/dmnew01.log
log file path: /d08/dmdbms/data/dmnew/dmnew02.log
write to dir [/d08/dmdbms/data/dmnew].
create dm database success. 2019-08-02 06:49:39
9.启动数据库：
dmserver /d08/dmdbms/data/dmnew/dm.ini
命令行下窗口不能关闭，否则数据库会关闭
10.注册服务
root用户下：
cd /d08/dmdbms/script/root
./dm_service_installer.sh -t dmserver -p dmserver -i /d08/dmdbms/data/dmnew/dm.ini
参数解释：
-t” “Service Type, include: dmimon,dmap,dmserver,dmwatch,dmrww,dmwmon,dmwatcher,dmmonitor,dmcss,dmcssm,dmasmsvr.”
-p” “Service Name Postfix, is invalid for dmimon,dmap.”
-i” “The path of the ini file, is invalid for dmimon,dmap.”
以服务方式启动数据库
service DmServicedmserver start
[root@ocp root]# ./dm_service_installer.sh -t dmserver -p dmserver -i /d08/dmdbms/data/dmnew/dm.ini
Move the service script file(/d08/dmdbms/bin/DmServicedmserver to /etc/rc.d/init.d/DmServicedmserver)
Finished to create the service (DmServicedmserver)
[dmdba@ocp ~]# service DmServicedmserver start
Starting DmServicedmserver: [ OK ]
完全默认方式建的库，实例名默认是dmserver ，sysdba用户密码也是默认SYDDBA，数据库名dmnew。
小结一下：
达梦数据库连接是通过ip和端口识别数据库的，不需要指定实例名（instance_name在dm.ini文件随时可以换）
另外达梦的技术文档都在安装目录的doc目录下（本例是/d08/dmdbms/doc）
