如何在postgresql中为数据库创build用户?

我在CentOS服务器上安装了PostgreSQL 8.4,并从shell连接到root用户并访问PostgreSQL shell。

我在PostgreSQL中创build了数据库和用户。

尝试从我的PHP脚本进行连接时,显示身份validation失败。

如何创build新用户以及如何授予他们特定数据库的权限?

从CLI:

 $ su - postgres $ psql template1 template1=# CREATE USER tester WITH PASSWORD 'test_password'; template1=# GRANT ALL PRIVILEGES ON DATABASE "test_database" to tester; template1=# \q 

PHP(在localhost上testing,它按预期工作):

  $connString = 'port=5432 dbname=test_database user=tester password=test_password'; $connHandler = pg_connect($connString); echo 'Connected to '.pg_dbname($connHandler); 

使用密码创build用户:

http://www.postgresql.org/docs/current/static/sql-createuser.html

 CREATE USER name [ [ WITH ] option [ ... ] ] where option can be: SUPERUSER | NOSUPERUSER | CREATEDB | NOCREATEDB | CREATEROLE | NOCREATEROLE | CREATEUSER | NOCREATEUSER | INHERIT | NOINHERIT | LOGIN | NOLOGIN | REPLICATION | NOREPLICATION | CONNECTION LIMIT connlimit | [ ENCRYPTED | UNENCRYPTED ] PASSWORD 'password' | VALID UNTIL 'timestamp' | IN ROLE role_name [, ...] | IN GROUP role_name [, ...] | ROLE role_name [, ...] | ADMIN role_name [, ...] | USER role_name [, ...] | SYSID uid 

然后授予特定数据库的用户权限:

http://www.postgresql.org/docs/current/static/sql-grant.html

例如:

 grant all privileges on database db_name to someuser;
