筆記-psql create role and assign user to the role with read only permission

最後有成功，所以先把過程記錄下來，再來研究該怎麼下指令。

建立一個 role 叫 dbreader

postgres=# CREATE ROLE dbreader;

CREATE ROLE

讓dbreader這個 role 可以讀取 public 這個 schema 的{usage | select}

postgres=# GRANT USAGE ON SCHEMA public TO dbreader;

GRANT

postgres=# GRANT SELECT ON ALL TABLES IN SCHEMA public TO dbreader;

GRANT

設定public schema 的default 權限 給 dbreader 這個 role

postgres=# ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT SELECT ON TABLES TO dbreader;

ALTER DEFAULT PRIVILEGES

建立資料庫使用者 readuser

postgres=# CREATE USER readuser WITH PASSWORD 'readuserpassword';

CREATE ROLE

將dbreader這個role 指定給 readuser

postgres=# GRANT dbreader TO readuser;

GRANT ROLE

切到 neo DB

postgres=# \q

postgres@hqs022:~$ psql --u postgres  neo

psql (9.6.8)

Type "help" for help.





neo=# GRANT SELECT ON ALL TABLES IN SCHEMA public to readuser;

GRANT



neo=# GRANT SELECT ON ALL SEQUENCES IN SCHEMA public TO readuser;

GRANT



neo=# GRANT ALL PRIVILEGES ON ALL FUNCTIONS IN SCHEMA public TO readuser;

GRANT
