Linux（Ubuntu平台）JSP通过JDBC连接MySQL数据库，与Windows平台类似，步骤如下：

下载 jdbc： mysql-connector-java-5.1.18.tar.gz

解压 jdbc： tar -zxvf mysql-connector-java-5.1.18.tar.gz

配置 jdbc：cp mysql-connector-java-5.1.18-bin.jar /usr/local/jdk1.6.0_22/jre/lib/ext/

配置JSP：

JSP示例：

<%@ page language="java" import="java.sql.*"%>
<%@ page language="java" import="java.io.*" %>
<html>
<head>
<title>Read from mySQL Database</title>
</head>
<body>
<p align="center"><b>Following records are selected from table "gametop800"</b><br>

<div align="center" width="85%">
