1 准备工作

安装好Linux操作系统这里选择的是Linux 7:

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

关闭防火墙 和 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

创建DM用户:

[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]# 

创建目录:存储dm数据库文件的空间需要提前规划并挂载好,我这里放在/dm目录下:

[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/

配置系统限制,在/etc/security/limits.conf 文件中添加如下内容:

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

配置环境变量:在dmdba用户的~/.bash_profile 里添加如下内容:

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

注意,在DM 软件安装时会自动添加DM_HOME 和 LD_LIBRARY_PATH 变量,这里只需要添加PATH即可。

2 安装DM 数据库

复制安装文件: 将DM的ISO上传到Linux系统,并挂载:

[root@slave1 software]# mount dm7开发版(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

将安装文件复制到/dm 目录下并修改安装文件权限:

[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

用dmdba用户执行./DMInstall.bin -i 程序,开始安装:

[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

解压安装程序.........

可打开文件数过少,建议至少设置为65536或更多。

欢迎使用达梦数据库安装程序 

是否输入Key文件路径"color: #ff0000">3 创建数据库实例

[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 注册数据库服务

注册的shell 脚本dm_service_installer.sh在DM_HOME/script/root目录下,执行注册时需要使用root用户执行。

[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.

创建服务(DmServicedmdba)完成

5 启动数据库

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

6 客户端连接

出现如下画面,说明安装成功,可以正常使用了。
