GBase 8a单机免费版安装，请先按照默认值操作，确保能正常安装使用。本文采用官方免费版本GBase8a-NoLicense-Free-8.6.2_build43-R7-redhat7.3-x86_64.tar.bz2为例，介绍单机版安装步骤。
目录导航
前提
请确认你的操作系统是redhat 7系列。
[root@localhost ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.3 (Maipo)
[root@localhost ~]#创建用户
我这里是gbase8用户。如果你已经有自己的用户，则无需创建了。
[root@localhost ~]# useradd gbase8 -m
[root@localhost ~]# chown gbase8:gbase8 GBase8a-NoLicense-Free-8.6.2_build43-R7-redhat7.3-x86_64.tar.bz2
将安装包复制到你的用户主目录下面
比如我例子中的/home/gbase/gbase8下面。本例是我通过root上传，然后mv过去的。请根据自己的情况，将安装包放过去。
注意之后我们都是在自己的gbase8用户下操作
[root@localhost ~]# mv GBase8a-NoLicense-Free-8.6.2_build43-R7-redhat7.3-x86_64.tar.bz2 /home/gbase8/
[root@localhost ~]# su - gbase8
[gbase8@localhost ~]$ ll

此处省略一大堆解压缩信息查看readme.txt
redame.txt里有常见的操作信息，包括安装，启动停止，登陆等，
[gbase8@localhost GBaseInstall]$ cat readme.txt
Guide:
1. To install
$ cd GBaseInstall
$ sh ./Install_lin.sh
$ source ~/.bashrc
2. To start&stop GBase
$ gbase.server start
$ gbase.server stop
$ gbase.server restart
3. To use GBase
$ gbase -uroot
4. To list all instance
$ cat $HOME/.gbase8a.properties_instance
5. To uninstall:
$ cd <installPath>
$ sh .server/bin/Uninstall_lin.sh
6. To Update
$ cd GBaseInstall
$ sh ./Install_lin.sh -U
$ source ~/.bash_profile
[gbase8@localhost GBaseInstall]$
安装
Install_lin.sh是安装脚本
其中所有的选项，我们都采用默认值即可，不需要修改。其中
安装目录默认是 /home/gbase8/GBase
默认的实例名是 gbase8a
默认端口是 5258
[gbase8@localhost GBaseInstall]$ ./Install_lin.sh

[gbase8@localhost GBase]$
加载环境变量
环境变量在~/.bashr 里面，我们直接加载这个文件。
[gbase8@localhost GBaseInstall]$ source ~/.bashrc看一下这个文件的内容，内部是加载/home/gbase8/.gbase_profile的。查看下.gbase_profile内容，都是环境变量相关的。
重要提示：数据库运行必须有响应的环境变量。
[gbase8@localhost GBaseInstall]$ cat ~/.bashrc
# .bashrc
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
# Uncomment the following line if you don't like systemctl's auto-paging feature:
# export SYSTEMD_PAGER=
# User specific aliases and functions
if [ -f "/home/gbase8/.gbase_profile" ]; then
. "/home/gbase8/.gbase_profile"
fi
[gbase8@localhost GBaseInstall]$ cat ~/.gbase_profile
export GBASE_BASE=/home/gbase8/GBase
export GBASE_HOME=/home/gbase8/GBase/server
export GBASE_SID=gbase8a
export PATH=$GBASE_HOME/bin:$PATH
export TCMALLOC_AGGRESSIVE_DECOMMIT=1
export LD_LIBRARY_PATH=$GBASE_HOME/lib/gbase/:$LD_LIBRARY_PATH
export TERMINFO=$GBASE_HOME/share/terminfo
[gbase8@localhost GBaseInstall]$
启动数据库服务
[gbase8@localhost GBaseInstall]$ gbase.server start
Starting GBase. SUCCESS!登陆数据库并测试建库建表等操作
