最近学习一款 南大通用 的事务型数据库 GBase 8s，感觉这款数据库非常具有可玩性。下面记录了我的 GBase 8s 数据库 安装信息，分享给大家。
安装环境说明
GBase 8s是一款典型的事务型数据库，类似于Oracle，MySQL等。这款数据库对安装环境要求不高，完全可以在虚拟机上安装和学习，甚至有版本可以部署到嵌入式环境中。
GBase 8s的硬件安装要求：
| 硬件 | 指标 |
|---|---|
| CPU | 2核或以上 |
| 内存 | 2G或以上 |
| 磁盘 | 10G或以上 |
| 网卡 | 千兆 |
我练习用的安装环境，是一台VMWare虚拟机，2核CPU，2G内存，千兆网卡，预分配了20G的磁盘空间。
GBase 8s的数据库组件安装完成后，大约有500M，但存储物理日志，逻辑日志，智能大对象，临时数据和事务数据都需要使用磁盘存储空间，建议至少有10G以上的磁盘空闲空间。
安装的操作系统CentOS 7.3。在安装时，选择的是开发和创新工作站（不是最小安装），安装后，大概有1500多个rpm包。安装后，关闭了SELinux和防火墙。

检查操作系统版本
[root@devsvr ~]# cat /etc/redhat-release
CentOS Linux release 7.3.1611 (Core)
安装前的准备工作
创建用户
GBase 8s数据库需要一个名字为gbasedbt的操作系统用户，做为数据库的超级用户。我们在安装前，需要创建好这个用户。
如果我们在安装时，没有提前创建这个用户，在安装过程中，会提示要创建这个用户，并输入密码。不过在安装过程中创建的用户，没有创建一个新的目录做为gbasedbt的Home，这可能导致在后续的创建数据库实例时，无法自动生成实例的环境变量。
为了减少后面的麻烦，记得提前创建gbasedbt用户，并设置好密码。切记切记，这一点对于初学者很重要。
检查操作系统是否存在gbasedbt用户
[root@devsvr ~]# cat /etc/passwd | grep gbasedbt
[root@devsvr ~]#
检查操作系统是否存在gbasedbt组
[root@devsvr ~]# cat /etc/group | grep gbasedbt
[root@devsvr ~]#
创建gbasedbt组和用户，并设置用户密码
[root@devsvr ~]# useradd gbasedbt
[root@devsvr ~]# passwd gbasedbt
Changing password for user gbasedbt.
New password: ******
BAD PASSWORD: The password is a palindrome
Retype new password: ******
passwd: all authentication tokens updated successfully.
创建gbasedbt后，再次查看
[root@devsvr ~]# cat /etc/group | grep gbasedbt
gbasedbt:x:1001:
[root@devsvr ~]# cat /etc/passwd | grep gbasedbt
gbasedbt:x:1001:1001::/home/gbasedbt:/bin/bash
[root@devsvr ~]#
gbasedbt的组和用户已经创建成功。
准备软件安装包
上传GBase 8s安装包到服务器。
[root@devsvr ~]# ls /root/setup/
GBase8s_ExpressEdition.tar
创建一个目录，将安装包解压到该目录
[root@devsvr ~]# mkdir install
[root@devsvr ~]# cd install/
[root@devsvr install]# tar xf /root/setup/GBase8s_ExpressEdition.tar
[root@devsvr install]# ls
doc ids_install ids.properties onsecurity
至此，安装数据库需要的软件包和用户都准备好了。
安装GBase 8s
安装GBase 8s数据库组件
GBase 8s数据库安装，支持图形界面方式和控制台的命令行方式。默认的安装方式是控制台命令行方式。如果希望使用图形界面安装，只需要在启动安装程序时，后面加上参数./ids_install -i swing即可。
安装过程中，会显示产品的License，内容较长，在控制台的命令行方式中，可以连续按5次回车。在图形界面方式中，需要用鼠标拉动界面右侧的滚动条到底部，就可以点那个复选框，确认License了。
我们在root用户下，进入安装包目录，运行安装命令ids_install，启动安装程序。
[root@devsvr install]# ./ids_install

: /opt/gbase
安装程序提示用户输入GBase 8s的安装路径。我们输入/opt/gbase。
说明：
- /opt目录的默认用户和用户组是root:root，如果被修改成其它用户和用户组，可能会导致安装时，报权限错误。请检查指定的安装路径用户和用户组是否为root:root。
- 如果数据库安装在/opt下，可以不用手动创建后面的目录，安装程序会自动创建。
- 为了保障数据安全，GBase 8s的安装路径，不能允许其它用户有写权限，即安装路径不能设置为777。建议将安装路径的权限设置为755.
- 安装目录中，必须为空。
INSTALL FOLDER IS: /opt/gbase
IS THIS CORRECT? (Y/N): y
输入y，确认安装路径。

Installation or Distribution
----------------------------
Select the installation type.
Typical: Install the database server with all features and a database server
that
is configured with default values. Includes:
** Client Software Development Kit (CSDK)
** Java Database Connectivity (JDBC)
Minimum disk space required: 700-800MB
Custom: Install the database server with specific features and software that
you need.
Optionally install a configured database server instance.
Minimum disk space required: 75 MB (without a server instance)
->1- Typical installation
2- Custom installation
3- Extract the product files (-DLEGACY option)
ENTER THE NUMBER FOR YOUR CHOICE, OR PRESS TO ACCEPT THE DEFAULT:: 1
安装程序支持典型安装和自定义安装方式，我们选择典型安装，所以输入1。
===============================================================================
Server Instance Creation
------------------------
Create a server instance?
->1- Yes - create an instance
2- No - do not create an instance
ENTER THE NUMBER FOR YOUR CHOICE, OR PRESS TO ACCEPT THE DEFAULT:: 2
在安装过程中，可以自动创建一个数据库的实例。由于典型安装中创建的实例在配置上非常简单，不适合后期深入的学习GBase 8s，因此我们选择不创建实例，我们在安装后，可以手动执行一个脚本，方便了创建一个新的数据库实例。此处我们输入2。
重要说明：
这个选择很重要。选择不创建实例，不但可以减少你的整体安装时间，也会让你对这款数据库，有更深入地了解。
安装过程中，自动创建一个数据库实例，在个别情况下，可能出现安装后，不能创建数据库现象（执行create database卡住，一段时间后报错退出）。这个问题的原因是sqlhosts文件中使用了机器名，需要我们修改成服务器的IP地址，并重启数据库，就可以解决。也许有其它好的解决方法，不过这是我目前知道的一个方法，而且好用。

至此，数据库的组件，全部安装完成。我们再创建一个数据库实例，就可以工作了。
创建数据库实例
创建数据库实例，需要切换到gbasedbt用户。
[root@devsvr ~]# su - gbasedbt
在数据库安装目录的etc目录有，有一个GBaseInit_gbasedbt.sh脚本，可以采用向导方式，让我们一步一步，方便地创建一个新的数据库实例。
GBase 8s不同于Oracle，MySQL和SQL Server等，支持在一台服务器上，部署多个实例，听说甚至可以部署不同版本的多个实例，对于那些服务器紧张的小伙伴，是个福利。大家有兴趣，可以自己尝试一下。
