需要lamp用于测试
1.安装httpd
yum -y install httpd``systemctl start httpd
2.安装数据库
yum -y install mariadb mariadb-server``systemctl start mariadb
3.安装php相关
yum install -y php php-devel php-fpm php-mysql php-common php-devel``systemctl start php-fpm
1.登陆数据库,默认安装的没密码
mysql
2.创建one库
create database one;
3.创建user表
create table one.user(id int(11),name cahr(20),password char(20));
4.写入一个数据
insert into one.user values(1,'abc','abcd');
1.创建一个首页文件
vim /var/www/html/index.html
<?php $servername = "localhost"; #数据库地址 $dbusername = "root"; #登陆 $dbpassword = ""; $dbname = "one"; #登陆后切换到哪个库 $username = $_GET ['username']; #从get方法获取参数 $password = $_GET ['password']; #登陆到数据库并建立连接 mysql_connect($servername,$dbusername,$dbpassword) or die ("数据库连接失败"); #查询语句,账号和密码从浏览器的get方法中获取 $sql = "SELECT * FROM user WHERE username='$username' AND password='$password'"; #切换到one库,并查询 $result = mysql_db_query($dbname, $sql); #获取查询的状态,是否成功 $userinfo = mysql_fetch_array($result); #判断一下,是否登陆成功 if (empty($userinfo)) { echo "登录失败"; } else { echo "登录成功"; } #输出sql语句,用于查看是否将username和password传进去 echo "<p>SQL Query:$sql<p>"; ?>
浏览器输入,可以看到登陆成功了。xx=x&xx=x是用get方法传递参数。
