linux网络操作系统大作业

1.搭建一个简单的apache+mysql+php组合：点击红帽子—>系统设置-->服务器设置服务勾上httpd然后点开始之后保存，如图：在浏览器测试如图：打开文件夹file:/var/www/html 在其中建一个about.php的文件，代码如下：<?Phpinfo();?>打开浏览器测试如图：点击红帽子—>系统设置-->服务器设置服务勾上mysqld然后点开始之后保存,然后在终端输入如图所示代码，给MYSQL设定密码，如图：2.根据题目要求需要数据库中建立学生个人信息（学号、性别、年龄），所修课成，所在院系三个表，不是独立的。

所以我建了一个名为php的数据库以及名为register（用户），student（学生），faculty（学院），course（课程）的数据表，代码如下：CREATE TABLE IF NOT EXISTS student (name varchar(30) NOT NULL,id int(30) NOT NULL,class char(30) NOT NULL,sex varchar(30) NOT NULL,age int(20) NOT NULL);CREATE TABLE IF NOT EXISTS register (username char(25) NOT NULL,password int(20) NOT NULL);INSERT INTO register VALUES('admin','111111');CREATE TABLE IF NOT EXISTS course (id int(30) NOT NULL,classname char(30) NOT NULL,classid int(20) NOT NULL,teacher varchar(30) NOT NULL,socre int(10) NOT NULL);CREATE TABLE IF NOT EXISTS faculty (id int(30) NOT NULL,name char(30) NOT NULL,academical char(30) NOT NULL);建数据库及数据表如图：3.下面进行管理员与数据库的连接：在file:/var/www/html file:/var/www/html建立一个名为学生信息管理系统的文件夹，然后建一个register.phpy以及denglu.html，代码如下：Register.php:<?php$username=$_POST['username'];$password=$_POST['password'];$con=mysql_connect("localhost","root","root");mysql_select_db("php");$sql="select * from register where username='$username' AND password='$password'";$re=mysql_query($sql);$row=mysql_num_rows($re);if($row!=1){echo "登录失败";}else echo "<meta http-equiv=refresh content=1;url=caozuo.html>";?>denglur.html:<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html;
