摘要：华为 GaussDB 100 安装数据库集群执行安装

1. 环境准备

1.1 系统规划

服务器类型	操作系统	IP	主机名	内存	磁盘
服务器 1	CentOS 7.4	192.168.8.48	gs-100-01	16G	200G
服务器 2	CentOS 7.4	192.168.8.49	gs-100-02	16G	200G
服务器 3	CentOS 7.4	192.168.8.50	gs-100-03	16G	200G

1.2 操作系统设置

操作系统安装

各集群系统节点操作系统必须一致
ROOT用户设置

各集群系统节点root密码设置一致
时间同步设置

转载参考：NTP 时钟同步设置
安装包准备

安装包存放到/opt目录下，并解压
目录结构如下：/opt/software/gaussdb/

2. 运行前置脚本

2.1 准备 clusterconfig.xml 文件

提供准确的 hostname 和 IP地址

2.2 运行前置脚本

root 用户下下运行

   /opt/software/gaussdb/script/gs_preinstall  -X ../clusterconfig.xml  -U omm -G dbgrp

命令运行结果如下

[root@gs-100-01 script]# ./gs_preinstall -X  ../clusterconfig.xml  -U omm -G dbgrp

4. 测试安装结果

4.1 连接数据库

omm 用户下

zsql omm@127.0.0.1:8000

4.2 数据库用户操作

查看数据库用户

SELECT * FROM DB_USERS;

修改用户密码

ALTER USER user_name IDENTIFIED BY new_password REPLACE old_password;

新建用户

CREATE USER jessica IDENTIFIED BY gaussdb_123;
GRANT CREATE SESSION TO Jessica；

建表

CREATE TABLE films(
id NUMBER(6) not null,
ADDRESS VARCHAR(40),
CITY VARCHAR(64)
) DISTRIBUTE BY HASH(id);

创建角色

CREATE ROLE role_r; 
GRANT SELECT ON films TO role_r; 
GRANT ROLE_R TO user_read;

查看系统用户权限

SELECT * FROM ADM_SYS_PRIVS WHERE GRANTEE ='JOE';

数据库内置用户列表

用户名	默认密码	备注
omm	gaussdb_123	dba 管理员用户
sys	Changeme_123	sys 用户
