创建用户和用户组
为了实现安装过程中安装帐户权限最小化，及安装后openGauss的系统运行安全性，安装脚本在安装过程中会自动按照用户指定内容创建安装用户，并将此用户作为后续运行和维护openGauss的管理员帐户。
- 用户组：dbgrp
[root@node0 ~]# groupadd dbgrp- 用户：omm
[root@node0 ~]# useradd -g dbgrp omm
[root@node0 ~]#
[root@node0 ~]# echo 'omm!666' | passwd --stdin omm
Changing password for user omm.
passwd: all authentication tokens updated successfully.
[root@node0 ~]#
[root@node0 ~]# id omm
uid=1001(omm) gid=1001(dbgrp) groups=1001(dbgrp)
创建目录
以root用户登录待安装openGauss的主机，并按规划创建存放安装包的目录。
不建议把安装包的存放目录规划到openGauss用户的根目录或其子目录下，可能导致权限问题。
openGauss用户须具有/opt/software/openGauss目录的读写权限。
[root@node0 ~]# mkdir -p /opt/software/openGauss
[root@node0 ~]# chmod 755 -R /opt/software
上传安装包
将安装包openGauss-5.0.0-openEuler-64bit-all.tar.gz上传至所创建的/opt/software/openGauss目录中
[root@node0 openGauss]# pwd
/opt/software/openGauss
[root@node0 openGauss]# ll
