创建实例

1 不带任何参数的方式

[[email protected] ~]$ 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].
create dm database success. 2029-02-28 15:40:44
[[email protected] ~]$

从结果看，有些参数虽然有默认值，但还是必须要选择。

 

2 带参数创建

虽然dminit有很多选项，这些选项都有默认值，尤其是涉及到page大小的，默认值大部分也是最佳的选择，所以我们只需要指定实例的创建路径和数据库名称即可。

[[email protected] ~]$ 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
[[email protected] ~]$

有可能 初始化数据库到  /opt/dmdbms/bin/DAMENG 目录

注册数据库服务

命令行创建的实例没有对应的服务，不能使用服务进行管理。所以在使用命令行创建实例之后进行注册，重新注册成系统服务，方便用户管理与控制。

2 Shell 脚本注册

注册的shell 脚本dm_service_installer.sh在DM_HOME/script/root目录下：

[[email protected] root]$ pwd
/dm/dmdbms/script/root
[[email protected] root]$ ls
dm_service_installer.sh  dm_service_uninstaller.sh  root_installer.sh
[[email protected] root]$

执行注册时需要使用root用户执行。

1.通过指定服务类型注册服务
[[email protected] root]# pwd
/dm/dmdbms/script/root
[[email protected] root]# ls
dm_service_installer.sh  dm_service_uninstaller.sh  root_installer.sh
[[email protected] 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)
[[email protected] root]# 
[[email protected] 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
[[email protected] root]# 

测试：
[[email protected] root]$ service DmServicedave status
DmServicedave is stopped
[[email protected] root]$ service DmServicedave start
Starting DmServicedave:                                    [ OK ]
[[email protected] root]$ service DmServicedave status
DmServicedave (pid 3556) is running...
[[email protected] root]$ service DmServicedave stop
Stopping DmServicedave:                                    [ OK ]
[[email protected] root]$ service DmServicedave status
DmServicedave is stopped
[[email protected] root]$


测试通过

 开机启动
  [[email protected] root]# systemctl enable DmServiceDMSERVER.service

 
启动服务
[[email protected] root]# systemctl start DmServiceDMSERVER.service
 
[[email protected] root]# systemctl status DmServiceDMSERVER.service
