Tutorial on installing DAMO database on Centos7

1. Preparation

After installing the Linux operating system, Linux 7 is selected here:

[root@slave1 software]# cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core)

Disable firewall and Selinux:

[root@slave1 software]# systemctl stop firewalld
[root@slave1 software]# systemctl disable firewalld
[root@slave1 software]# vi /etc/selinux/config
[root@slave1 software]# cat /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted

Create a DM user:

[root@slave1 software]# groupadd dinstall
[root@slave1 software]# useradd -g dinstall -m -d /home/dmdba -s /bin/bash dmdba
[root@slave1 software]# passwd dmdba
Changing password for user dmdba.
New password: 
BAD PASSWORD: The password is shorter than 8 characters
Retype new password: 
passwd: all authentication tokens updated successfully.
[root@slave1 software]#

Create a directory: The space for storing dm database files needs to be planned and mounted in advance. I put it in the /dm directory:

[root@slave1 software]# mkdir -p /dm/dmdbms
[root@slave1 software]# mkdir -p /dm/dmarch
[root@slave1 software]# mkdir -p /dm/dmbak
[root@slave1 software]# chown -R dmdba:dinstall /dm/
[root@slave1 software]# chmod -R 775 /dm/

Configure system limits and add the following to the /etc/security/limits.conf file:

[root@slave1 software]# vim /etc/security/limits.conf
dmdba soft nofile 65536
dmdba hard nofile 65536

Configure environment variables: Add the following content to the ~/.bash_profile of the dmdba user:

export DM_HOME="/dm/dmdbms"
export LD_LIBRARY_PATH="/dm/dmdbms/bin:$LD_LIBRARY_PATH"
export PATH="/dm/dmdbms/bin:$PATH"

Note that the DM_HOME and LD_LIBRARY_PATH variables are automatically added when the DM software is installed. Here you only need to add PATH.

2 Installing the DM database

Copy the installation file: Upload the DM ISO to the Linux system and mount it:

[root@slave1 software]# mount dm7 development version (rh7-64) 20190917.iso /mnt/
mount: /dev/loop0 is write-protected, mounting read-only
[root@slave1 software]# cd /mnt/
[root@slave1 mnt]# ls
DMInstall.bin DM_Install_en.pdf DM_Install_zh.pdf release_en.txt release_zh.txt

Copy the installation file to the /dm directory and modify the installation file permissions:

[root@slave1 mnt]# pwd
/mnt
[root@slave1 mnt]# cp ./DMInstall.bin /dm/
[root@slave1 mnt]# cd /dm
[root@slave1 dm]# ll
total 573076
drwxrwxr-x 2 dmdba dinstall 6 Dec 9 23:08 dmarch
drwxrwxr-x 2 dmdba dinstall 6 Dec 9 23:08 dmbak
drwxrwxr-x 2 dmdba dinstall 6 Dec 9 23:08 dmdbms
-r-xr-xr-x 1 root root 586828259 Dec 9 23:14 DMInstall.bin
[root@slave1 dm]# chown dmdba:dinstall DMInstall.bin
[root@slave1 dm]# ll
total 573076
drwxrwxr-x 2 dmdba dinstall 6 Dec 9 23:08 dmarch
drwxrwxr-x 2 dmdba dinstall 6 Dec 9 23:08 dmbak
drwxrwxr-x 2 dmdba dinstall 6 Dec 9 23:08 dmdbms
-r-xr-xr-x 1 dmdba dinstall 586828259 Dec 9 23:14 DMInstall.bin

Execute the ./DMInstall.bin -i program as the dmdba user to start the installation:

[root@slave1 dm]$ pwd
/dm
[root@slave1 dm]$ ./DMInstall.bin -i
Please select the installer's language (E/e:English C/c:Chinese) [E/e]:c

Unzip the installer...

The number of open files is too small. It is recommended to set it to at least 65536 or more.

3 Create a database instance

[root@slave1 bin]$ pwd
/dm/dmdbms/bin
[root@slave1 bin]$ ./dminit PATH=/dm/dmdbms/data DB_NAME=dmdba INSTANCE_NAME=DMDBA CTL_PATH=/dm/dmdbms/data/dmdba/dm.ctl CASE_SENSITIVE=N CHARSET=1
initdb V7.6.0.197-Build(2019.09.12-112648)ENT 
db version: 0x7000a
file dm.key not found, use default license!
License will expire on 2020-09-12
 
 log file path: /dm/dmdbms/data/dmdba/dmdba01.log
 
 
 log file path: /dm/dmdbms/data/dmdba/dmdba02.log
 
write to dir [/dm/dmdbms/data/dmdba].
create dm database success. 2019-12-09 23:25:17

4 Registration database service

The registered shell script dm_service_installer.sh is in the DM_HOME/script/root directory and needs to be executed by the root user.

[root@slave1 bin]# cd /dm/dmdbms/script/root
[root@slave1 root]# ./dm_service_installer.sh -t dmserver -i /dm/dmdbms/data/dmdba/dm.ini -p dmdba
Created symlink from /etc/systemd/system/multi-user.target.wants/DmServicedmdba.service to /usr/lib/systemd/system/DmServicedmdba.service.

Create service (DmServicedmdba) completed

5 Start the database

[root@slave1 root]# systemctl enable DmServicedmdba.service
[root@slave1 root]# systemctl start DmServicedmdba

6 Client Connection

The following screen appears, indicating that the installation is successful and can be used normally.
