HAWQ配置之客戶端訪問

1、配置簡單的口令訪問

1，創建數據庫和用戶

postgres=# create database epbd;
CREATE DATABASE
postgres=# create role user1 with login;
NOTICE:  resource queue required -- using default resource queue "pg_default"
CREATE ROLE
postgres=# alter role user1 with password 'user1';
ALTER ROLE
postgres=# grant all on epbd to user1;
ERROR:  relation "epbd" does not exist
postgres=# grant all on database epbd to user1;
GRANT

 

2，修改master訪問配置文件pg_hba.conf，添加一個口令訪問用戶

local    all         gpadmin         ident
host     all         gpadmin         127.0.0.1/28    trust
host  all     gpadmin    ::1/128       trust
host  all     gpadmin    192.168.58.15/32       trust
host  all     gpadmin    fe80::4ecc:6aff:fe93:3250/128       trust
host  all     gpadmin    192.168.58.11/32       trust
local all yh password
host all user1 192.168.0.0/16         password

 

3，重載配置文件使之生效

 hawq stop cluster -u -a -M fast

注意這個命令並不是中止集羣，只是爲了從新裝載配置。
