Getting Started with Dameng Database: Installing and Uninstalling Dameng 8 (Linux)

2. Plan installation users and installation paths

1), first use the root user to create a user group dmgroup

[root@localhost ~]# groupadd dmgroup

2), and then create user dmdba

[root@localhost ~]# useradd -g dinstall dmdba

3), Plan the installation directory, and set the permissions of the directory to the dmdba user

[root@localhost /]# mkdir /dmteamo
[root@localhost /]# chown dmdba.dinstall -R /dmteamo

3. Configure environment variables,
switch the login user to dmdba, and then configure the environment variable file .bash_profile file in the /home/dmdba directory

[root@localhost /]# su dmdba
[dmdba@localhost /]# cd /home/dmdba
[dmdba@localhost dmdba]# vi .bash_profile

在打开的文件末尾加入下面内容
export DM_HOME=/dmteamo
export PATH=$DM_HOME/bin:$PATH:$HOME/.local/bin:$HOME/bin

保存文件后，执行下面命令是环境变量生效
[dmdba@localhost dmdba]# source  .bash_profile

4. Prepare the installation file (the author takes the .iso file as an example)

首先使用root用户挂在iso文件
[root@localhost 桌面]# mount -o loop dm8_20201107_x86_rh6_64_ent_8.1.1.144.iso /mnt
[root@localhost 桌面]# cd /mnt
[root@localhost mnt]# ls
DM8 Install.pdf  DMInstall.bin
当看到DMInstall.bin文件，就说明安装文件已经成功挂载

5. Install the database

1. Use the GUI to install
First use the root user to share the desktop

[root@localhost mnt] xhost +

Switch to dmdba user

[root@localhost mnt]# su dmdba

Execute the installation command

[dmdba@localhost mnt]./DMInstall.bin

Select [Typical Installation] to install the server and client, select [Server Installation] to install only the server, select [Client Installation] to install only the client, and select [Custom Installation] to install it according to user needs

Enter the directory to be installed, click Next

and click Install

After the installation is complete, use the root user to execute the following commands as required

root@localhost /]# /dmteamo/script/root/root_installer.sh

So far, the database installation is complete

2. Use the command mode to install
Switch to the dmdba user, cd to the /mnt directory

[root@localhost 桌面]$ su -dmdba
[root@localhost 桌面]$ cd /mnt

Execute the following command

[dmdba@localhost mnt]$ ./DMInstall.bin -i

Then follow the prompts step by step to operate

So far, the database installation is successful!

6. Uninstall the database
Switch to the dmdba user, cd to the data installation directory, and execute the /uninstall.sh command

[root@localhost mnt]su dmdba
[dmdba@localhost mnt]cd /dmteamo
[dmdba@localhost dmteamo]$ ./uninstall.sh

Pop up the uninstall pop-up window, click the OK button,

then click the uninstall button


, and finally execute the following command as required

[root@localhost dmteamo]# /dmteamo/root_uninstaller.sh

Click the Finish button, and the database is successfully uninstalled!
