LAMP环境下动态网站许愿墙的搭建

在进行搭建前进行环境的准备，这里使用的是Linux发行版CentOS 7

1.安装并启动Apache+Mysql并将文件放到Apache根目录下 /val/www/html

安装和启动的方法参考：http://www.cnblogs.com/dagege/p/5949620.html

2.首先我们先在数据库中建立一个用户‘dagege‘,创建一个数据库‘xyq‘,给用户‘dagege‘对数据库‘xyq‘的所有权限！

[[email protected] ~]# mysql -u root -p   #进入数据库
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 4

Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement.

mysql> create user ‘dagege‘@‘127.0.0.1‘ identified by ‘DAGEGE‘;　　　　#创建用户和密码，并且绑定ip
Query OK, 0 rows affected (0.00 sec)

mysql> create database xyq;　　　　#创建数据库
Query OK, 1 row affected (0.00 sec)

mysql> grant all privileges on xyq.* to ‘dagege‘@‘127.0.0.1‘;　　　　#给来自IP:127.0.0.1的‘dagege‘用户对数据库xyq所有的权限
Query OK, 0 rows affected (0.00 sec)

3.进入数据库‘xyq‘，并导入sql文件(给的链接解压出来就是了)

mysql> use xyq;　　　　#进入数据库
Database changedmysql> [复制两个sql文件的全部内容粘贴过来]　　　　　　#导入sql文件

4.安装php-mysql（配置本地yum源）

[[email protected] XYQ]# yum install php-mysql
已加载插件：fastestmirror, langpacks

正在解决依赖关系
There are unfinished transactions remaining. You might consider running yum-complete-transaction, or "yum-complete-transaction --cleanup-only" and "yum history redo last", first to finish them. If those don‘t work you‘ll have to try removing/installing packages by hand (maybe package-cleanup can help).

5.修改文件connect.php 然后保存！

[[email protected] XYQ]# vim connect.php 

<?php
$host="127.0.0.1";　　　　//这里写mysql主机的ip
$db_user="dagege";　　　　//这里写我们刚刚创建的用户名
$db_pass="DAGEGE";　　　　//这里写密码
$db_name="xyq";　　　　　//这里写我们创建的数据库
$timezone = "Asia/Shanghai";

$link=mysql_connect($host,$db_user,$db_pass);
mysql_select_db($db_name,$link);
mysql_query("SET names UTF8");

header("Content-Type: text/html; charset=utf-8");
date_default_timezone_set($timezone); //北京时间
?>
~        

 6.重启Apache服务，关闭防火墙和selinux

[[email protected] XYQ]# systemctl restart httpd.service

[[email protected] XYQ]# systemctl stop firewalld.service

[[email protected] XYQ]# setenforce 0
