Penrose连接Mysql解决方案Mysql 设置

 最近一直在进行Penrose连接Mysql的尝试，可总是提示无法连接到Mysql，无论是检查端口是否开启，设置Mysql远程访问权限等都不管用，后来在Penrose的官网找到一个建立样例数据库及设置远程连接的文档，没想到一举成功，痛快啊！

下面就把文档和大家共享一下！（是英文，大家就凑合着看下吧！因为最近搞Penrose太累了，懒的再去翻译了！）

我安装的Penrose版本是2.0的，Mysql是5.0

The following are the instructions to setup the sample database. The instructions were written for MySQL 4.x, but you can use other database systems.

Create Database

Make sure you have a MySQL server running on your local machine. Create a MySQL database called "penrose_demo". Exececute the following commands inside a MySQL client:

create database penrose_demo;

Create Database User

Create a MySQL user called "penrose" with password "penrose". Exececute the following commands inside a MySQL client:

grant all privileges on *.* to 'penrose'@'<hostname>' identified by 'penrose' with grant option;

grant all privileges on *.* to 'penrose'@'localhost' identified by 'penrose' with grant option;

grant all privileges on *.* to 'penrose'@'%' identified by 'penrose' with grant option;

注：主要是这边关于权限的设置导致我总是连接不成功！有高手能详细解释下不？

Change the <hostname> with your machine name.

Create Database Tables

Populate the database with the SQL script provided in PENROSE_HOME/samples/sql. Exececute the following commands inside a MySQL client:

use penrose_demo;

source PENROSE_HOME/samples/sql/example.sql;

注：此脚本在相应目录中没有，需自己准备sql脚本！可在mysql官网上下载到！

The script was written for MySQL 4.x. If you are using a different database system, you might need to modify the script.
