GBase 8s 事务型数据库的安装与卸载详情

GBase 8s 事务型数据库的安装与卸载详情

最近学习了一款事务型数据库 GBase 8s。下面记录了GBase 8s 数据库的安装信息，分享给大家。

一、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

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。

1.检查服务器内存大小

[root@devsvr ~]# free -m
              total        used        free      shared  buff/cache   available
Mem:           1823         531         816           9         475        1079
Swap:          2047         125        1922

2.检查服务器磁盘空间大小

[root@devsvr ~]# df -h
Filesystem           Size  Used Avail Use% Mounted on
/dev/mapper/cl-root   17G  4.7G   13G  28% /
devtmpfs             897M     0  897M   0% /dev
tmpfs                912M  144K  912M   1% /dev/shm
tmpfs                912M  9.0M  903M   1% /run
tmpfs                912M     0  912M   0% /sys/fs/cgroup
/dev/sda1           1014M  174M  841M  18% /boot
tmpfs                183M   24K  183M   1% /run/user/0
/dev/sr0             7.8G  7.8G     0 100% /run/media/root/CentOS 7 x86_64

3.检查服务器网络配置信息

[root@devsvr ~]# ifconfig
ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.3.8  netmask 255.255.255.0  broadcast 192.168.3.255
        inet6 fe80::3c21:b180:c110:a31c  prefixlen 64  scopeid 0x20<link>
        ether 00:50:56:31:8f:de  txqueuelen 1000  (Ethernet)
        RX packets 333491  bytes 336973337 (321.3 MiB)
        RX errors 0  dropped 0  overruns 0  frame 0

        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

        inet 127.0.0.1  netmask 255.0.0.0

virbr0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        inet 192.168.122.1  netmask 255.255.255.0  broadcast 192.168.122.255
        ether 52:54:00:90:0c:05  txqueuelen 1000  (Ethernet)

        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

4.检查操作系统版本

[root@devsvr ~]# cat /etc/redhat-release
CentOS Linux release 7.3.1611 (Core) 

二、安装前的准备工作

1.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。

2.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。

三、安装GBase 8s

1.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
