創建實例
1 不帶任何參數的方式
[dave@www.cndba.cn ~]$ dminit
initdb V7.6.0.95-Build(2018.09.13-97108)ENT
db version: 0x7000a
file dm.key not found, use default license!
License will expire on 2029-03-14
input system dir:
input db name:
input port num:
input page size(4, 8, 16, 32):
input err , input again:
input err , input again:
input err , input again:8
input extent size(16, 32):
input err , input again:16
input time zone(-12:59,+14:00): +8
string case sensitive? ([Y]es, [N]o):
input err , input again:Y
which charset to use? (0[GB18030], 1[UTF-8], 2[EUC-KR]): 0
length in char? ([Y]es, [N]o): Y
enable database encrypt? ([Y]es, [N]o):
input err , input again:N
page check mode? (0/1/2): 0
input elog path:
auto_overwrite mode? (0/1/2):
input err , input again:0
log file path: /home/dmdba/DAMENG/DAMENG01.log
log file path: /home/dmdba/DAMENG/DAMENG02.log
write to dir [/home/dmdba/DAMENG].

[dave@www.cndba.cn ~]$
從結果看，有些參數雖然有默認值，但還是必須要選擇。
2 帶參數創建
雖然dminit有很多選項，這些選項都有默認值，尤其是涉及到page大小的，默認值大部分也是最佳的選擇，所以我們只需要指定實例的創建路徑和數據庫名稱即可。
[dave@www.cndba.cn ~]$ dminit PATH=/dm/dmdbms/data DB_NAME=cndba INSTANCE_NAME=dave
initdb V7.6.0.95-Build(2018.09.13-97108)ENT
db version: 0x7000a
file dm.key not found, use default license!
License will expire on 2029-03-14
log file path: /dm/dmdbms/data/cndba/cndba01.log
log file path: /dm/dmdbms/data/cndba/cndba02.log
write to dir [/dm/dmdbms/data/cndba].
create dm database success. 2029-02-28 15:48:12
[dave@www.cndba.cn ~]$
有可能 初始化數據庫到 /opt/dmdbms/bin/DAMENG 目錄注冊數據庫服務
命令行創建的實例沒有對應的服務，不能使用服務進行管理。所以在使用命令行創建實例之后進行注冊，重新注冊成系統服務，方便用戶管理與控制。
2 Shell 腳本注冊
注冊的shell 腳本dm_service_installer.sh在DM_HOME/script/root目錄下：
[dave@www.cndba.cn root]$ pwd
/dm/dmdbms/script/root
[dave@www.cndba.cn root]$ ls
dm_service_installer.sh dm_service_uninstaller.sh root_installer.sh
[dave@www.cndba.cn root]$
執行注冊時需要使用root用戶執行。
1.通過指定服務類型注冊服務
[root@dm2 root]# pwd
/dm/dmdbms/script/root [root@dm2 root]# ls dm_service_installer.sh dm_service_uninstaller.sh root_installer.sh [root@dm2 root]# ./dm_service_installer.sh -t dmserver -i /dm/dmdbms/data/cndba/dm.ini -p dave Move the service script file(/dm/dmdbms/bin/DmServicedave to /etc/rc.d/init.d/DmServicedave) Finished to create the service (DmServicedave) [root@dm2 root]# [root@dm2 root]# ll /etc/rc.d/init.d/DmServicedave -rwxr-xr-x 1 root root 12394 Feb 28 16:15 /etc/rc.d/init.d/DmServicedave [root@dm2 root]# 測試： [dave@www.cndba.cn root]$ service DmServicedave status DmServicedave is stopped [dave@www.cndba.cn root]$ service DmServicedave start Starting DmServicedave: [ OK ] [dave@www.cndba.cn root]$ service DmServicedave status DmServicedave (pid 3556) is running... [dave@www.cndba.cn root]$ service DmServicedave stop Stopping DmServicedave: [ OK ] [dave@www.cndba.cn root]$ service DmServicedave status DmServicedave is stopped [dave@www.cndba.cn root]$測試通過
開機啟動
[root@test01 root]# systemctl enable DmServiceDMSERVER.service
啟動服務
[root@test01 root]# systemctl start DmServiceDMSERVER.service
[root@test01 root]# systemctl status DmServiceDMSERVER.service
