DM V8数据库介质下载地址：

https://eco.dameng.com/download/

安装文档：

https://eco.dameng.com/docs/zh-cn/start/install-dm-linux-prepare.html

安装前准备：

新建 dmdba 用户

创建用户所在的组，命令如下：
groupadd dinstall
创建用户，命令如下：
useradd -g dinstall -m -d /home/dmdba -s /bin/bash dmdba
修改用户密码，命令如下：
passwd dmdba

修改文件打开最大数

重启服务器后永久生效
使用 vi 编辑器打开 /etc/security/limits.conf 文件，命令如下：
vi /etc/security/limits.conf
在最后添加四条语句，需添加的语句如下：
dmdba hard nofile 65536
dmdba soft nofile 65536
dmdba hard stack 32768
dmdba soft stack 16384
切换到 dmdba 用户，查看是否生效，命令如下
su - dmdba
ulimit -a
设置参数临时生效
可使用 dmdba 用户执行如下命令，使设置临时生效：
ulimit -n 65536

准备安装介质

切换到 root 用户，将 DM 数据库的 iso 安装包保存在任意位置，例如 /opt 目录下，执行如下命令挂载镜像：

[root@cjcos02 opt]# unzip dm8_20210818_x86_rh7_64_ent.zip 
[root@cjcos02 opt]# ll -rth
total 741M
drwxr-xr-x. 2 root root    6 Sep  5  2017 rh
drwxr-xr-x  3 root root   22 Jan 25  2020 ORCLfmap
drwxr-xr-x  2 root root  127 Aug 20 10:42 dm8_20210818_x86_rh7_64_ent
-rw-r--r--  1 root root 741M Nov 19 21:59 dm8_20210818_x86_rh7_64_ent.zip

解决安装介质

[root@cjcos02 dm8_20210818_x86_rh7_64_ent]# ll -rth
total 752M
-rw-r--r-- 1 root root  167 Aug 20 09:06 dm8_20210818_x86_rh7_64_ent_8.1.2.18_pack13.iso_SHA256.txt
-rw-r--r-- 1 root root 752M Aug 20 09:06 dm8_20210818_x86_rh7_64_ent_8.1.2.18_pack13.iso

挂载安装介质

[root@cjcos02 dm8_20210818_x86_rh7_64_ent]# mount -o loop dm8_20210818_x86_rh7_64_ent_8.1.2.18_pack13.iso /mnt
mount: /dev/loop0 is write-protected, mounting read-only

新建安装目录

在根目录下创建 /dm8 文件夹，用来安装 DM 数据库。命令如下： 
mkdir /dm8

修改安装目录权限

将新建的安装路径目录权限的用户修改为 dmdba，用户组修改为 dinstall。命令如下： 
chown dmdba:dinstall -R /dm8/
给安装路径下的文件设置 755 权限。命令如下：
chmod -R 755 /dm8

数据库安装

DM 数据库在 Linux 环境下支持命令行安装和图形化安装，本章节主要介绍命令行安装。

命令行安装

切换至 dmdba 用户下，在 /mnt 目录下使用命令行安装数据库程序，依次执行以下命令安装 DM 数据库。

su - dmdba
[dmdba@cjcos02 ~]$ cd /mnt/
[dmdba@cjcos02 mnt]$ ls
DM8 Install.pdf  DMInstall.bin
[dmdba@cjcos02 mnt]$ ./DMInstall.bin --help
Failed to get the parameter of the install mode! the default mode is GUI Install, Command-Line Install: ./DMInstall -i, Silent Install: ./DMInstall -q confi_file_path
[dmdba@cjcos02 mnt]$ ./DMInstall.bin -i

配置环境变量

切换到 root 用户进入 dmdba 用户的根目录下，配置对应的环境变量。
DM_HOME 变量和动态链接库文件的加载路径在程序安装成功后会自动导入。命令如下：
[dmdba@cjcos02 ~]$ cat .bash_profile 
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
#PATH=$PATH:$HOME/.local/bin:$HOME/bin
#export PATH
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/dm8/bin"
export DM_HOME="/dm8
export PATH=$PATH:$DM_HOME/bin:$DM_HOME/tool
切换至 dmdba 用户下，执行以下命令，使环境变量生效。
su - dmdba
source .bash_profile

配置实例

DM 数据库在 Linux 环境支持命令行配置实例以及图形化配置实例。

命令行配置实例

使用 dmdba 用户配置实例，进入到 DM 数据库安装目录下的 bin 目录中，使用 dminit 命令初始化实例。

dminit 命令可设置多种参数，可执行如下命令查看可配置参数。

[dmdba@cjcos02 bin]$ pwd

/dm8/bin

查看dminit参数

需要注意的是页大小 (page_size)、簇大小 (extent_size)、大小写敏感 (case_sensitive)、字符集 (charset) 这四个参数，一旦确定无法修改，需谨慎设置。
extent_size 指数据文件使用的簇大小，即每次分配新的段空间时连续的页数。只能是 16 页或 32 页或 64 页之一，缺省使用 16 页。
page_size 数据文件使用的页大小，可以为 4 KB、8 KB、16 KB 或 32 KB 之一，选择的页大小越大，则 DM 支持的元组长度也越大，但同时空间利用率可能下降，缺省使用 8 KB。
case_sensitive 标识符大小写敏感，默认值为 Y 。当大小写敏感时，小写的标识符应用双引号括起，否则被转换为大写；当大小写不敏感时，系统不自动转换标识符的大小写，在标识符比较时也不区分大小写，只能是 Y、y、N、n、1、0 之一。
charset 字符集选项。0 代表 GB18030；1 代表 UTF-8；2 代表韩文字符集 EUC-KR；取值 0、1 或 2 之一。默认值为 0。

可以使用默认参数初始化实例，需要附加实例存放路径，命令如下：

./dminit path=/dm/data

也可以自定义初始化实例的参数，参考如下示例：

以下命令设置页大小为 32 KB，簇大小为 32 KB，大小写敏感，字符集为 utf_8，数据库名为 DMDB，实例名为 DBSERVER，端口为 5237。

mkdir /dm8data
chown dmdba.dinstall /dm8data

注册服务

命令行注册服务：

注册服务需使用 root 用户进行注册。使用 root 用户进入数据库安装目录的 /script/root 下，如下所示：

cd /dm8/script/root

注册服务，如下所示：

[root@cjcos02 root]#  ./dm_service_installer.sh -t dmserver -dm_ini /dm8data/DMDB/dm.ini -p DMSERVE
Created symlink from /etc/systemd/system/multi-user.target.wants/DmServiceDMSERVER.service to /usr/lib/systemd/system/DmServiceDMSERVER.service.
Finished to create the service (DmServiceDMSERVER)

用户可根据自己的环境更改 dm.ini 文件的路径以及服务名，如下所示：

./dm_service_installer.sh -h

如需为其他实例注册服务，需打开 dbca 工具，进行注册服务，如下所示：

cd /dm8/tool
./dbca.sh

启停数据库

命令行启停数据库

服务注册成功后，启动数据库，如下所示：
