一、概念
1、框架结构
LAMP：linux+apache+mysql+PHP
系统+服务器程序+数据管理软件+中间软件
二、静态站点
1、安装Apache
（1）[root@localhost ~]# yum -y install httpd
//安装
[root@localhost ~]# systemctl start httpd
//启动
[root@localhost ~]# systemctl enable httpd
//设置开机自启动
[root@localhost ~]# systemctl stop firewalld
//临时关闭
[root@localhost ~]# setenforce 0
//关闭防火墙
[root@localhost ~]# httpd -v
//查看版本
Server version: Apache/2.4.6 (CentOS)
Server built: Mar 24 2022 14:57:57
2、虚拟主机
服务器：
目的： 在一台物理服务器上运行多个网站
类型：基于域名（主机名）
www.a站点设置：
（1）准备网站源码（网页）目录
[root@localhost ~]# mkdir /var/www/html/a.org
[root@localhost ~]# vim /var/www/html/a.org/index.html
//写内容在www.a.org网页中
（2）创建a.org的网站配置文件
[root@localhost ~]# vim /etc/httpd/conf.d/a.org.conf
<VirtualHost *:80>//
ServerName www.a.org//虚拟网站的名称（用于区别）
DocumentRoot /var/www/html/a.org//网页根目录
</VirtualHost>
（3）检测配置文件语法，重启服务
[root@localhost ~]# httpd -t
//检测
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message
Syntax OK
[root@localhost ~]# systemctl start httpd
//重启
客户端：
（1）linux客户端域名解析
[root@localhost ~]# vim /etc/hosts
192.168.32.138 www.a.org
（2）linux客户端测试网站可用性
用客户端访问服务器域名
三、动态网站
部署论坛系统
1、安装LAMP
[root@localhost ~]# yum -y install httpd mariadb-server mariadb php php-mysql gd php-gd
[root@localhost ~]# systemctl start httpd mariadb
//重启
（1）创建网站源码
[root@localhost ~]# wget http://download.comsenz.com/DiscuzX/2.5/Discuz_X2.5_SC_UTF8.zip
//下载压缩包

[root@localhost ~]# mkdir -p /webroot/discuz

[root@localhost ~]# unzip Discuz_X2.5_SC_UTF8.zip
//解压
[root@localhost ~]# cp -rf upload/* /webroot/discuz/
//把upload中的所有文件复制到/webroot/discuz中
