一、LAMP
1.LAMP的含义
- L代表服务器操作系统使用Linux
- A代表网站服务使用的是Apache软件基金会中的httpd软件
- M代表网站后台使用的数据库是MySQL数据库
- P代表网站是使用PHP/Perl/Python等语言开发
2.A/M/P的作用
2.1 Apache（httpd）
- 作用：提供web服务，接受用户的连接请求
- 注意：Apache或Nginx都只支持静态页面的解析
①静态网页
- 静态网页指使用HTML（超文本标记语言）编写，一般后缀为.htm，.html等；网页文件中没有程序代码。
- 静态页面，用户双击打开，看到的效果与web服务器是相同的，因为网页的内容在用户访问之前就已经确定。
②动态网页
- 动态网页指网站使用特定的编程语言编写，网页文件中除了HTML标记以外，还包括一些实现特定功能的程序代码。
- 服务端可以根据客户端的不同请求动态产生网页内容。
- 动态网页后缀一般为.php .asp .aspx .cgi .perl .jsp等
- 常见的留言板，论坛，注册，发帖都是用动态网页实现的。
2.2 PHP
- 作用：PHP主要负责PHP脚本程序的解析以及实现与MySQL数据库的交互工作，动态页面中的注册/登陆/下单/支付等大多数功能都是基于PHP+MySQL进行实现。PHP是一种通用开源脚本语言。
1、当客户端请求的是动态资源时，apache（httpd程序）会调用libphpX.so模块进行相应的解析
2、如果解析处理需要用到后台数据库相关数据，此时php程序也会连接后台数据库
3、最终php程序将解析后的结果返回给apache（httpd程序），让apache返回给客户
2.3 MySQL数据库
- 作用：MySQL是一个关系型数据库管理系统，由瑞典MySQL AB公司开发，目前属于Oracle旗下产品。其主要作用用于永久的存储数据
二、LAMP架构部署
环境说明：
| 系统平台 | IP | 安装的服务 |
|---|---|---|
| CentOS8 | 192.168.92.131 | httpd-2.4 mysql-5.7 php php-mysql |
服务安装次序：
- httpd --> mysql --> php
注意：php要求httpd使用prefork MPM
用到的网站链接：
- Apache官网
- MySQL官网
- PHP官网
- Linux的rpm包站

2.1 mysql可能遇到的报错
//首先登录遭遇的报错问题
[root@LAMP mysql]# mysql -uroot -p'H6e9f,Jt3
mysql: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory

3.1php可能遇到的报错
1、sqlite3
//报错信息
configure: error: Package requirements (sqlite3 > 3.7.4) were not met:
Package 'sqlite3', required by 'virtual:world', not found
解决方式：
[root@LAMP ~]# dnf -y install libsqlite3x-devel
2、oniguruma
//报错信息
configure: error: Package requirements (oniguruma) were not met:
Package 'oniguruma', required by 'virtual:world', not found
解决方式：
[root@LAMP ~]# dnf -y install http://mirror.centos.org/centos/8-stream/PowerTools/x86_64/os/Packages/oniguruma-devel-6.8.2-2.el8.x86_64.rpm
4.配置 apache
4.1 启动代理模块
在apache httpd 2.4以后已经专门有一个模块针对FastCGI的实现，此模块为mod_proxy_fcgi.so，它其实是作为mod_proxy.so模块的扩展，因此，这两个模块都要加载，编辑httpd.conf文件，取消以下两行内容的注释:
- LoadModule proxy_module modules/mod_proxy.so
- LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so
//启用httpd的相关模块
[root@LAMP ~]# sed -i '/proxy_module/s/#//g' /usr/local/apache/conf/httpd.conf
[root@LAMP ~]# sed -i '/proxy_fcgi_module/s/#//g' /usr/local/apache/conf/httpd.conf
//这里的$1表示匹配所有以.php结尾的http请求
4.2 配置虚拟主机
在需要使用fcgi的虚拟主机中添加类似如下两行：
ProxyRequests Off //关闭正向代理
ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/PATH/TO/DOCUMENT_ROOT/$1
实战演示：
[root@LAMP extra]# pwd
/usr/local/apache/conf/extra
[root@LAMP extra]# vim httpd-vhosts.conf
<VirtualHost *:80>
DocumentRoot "/usr/local/apache/htdocs/yf"
ServerName yf.example.com
ErrorLog "yf.example.com-error_log"
CustomLog "yf.com-access_log" common
ProxyRequests Off
ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/usr/local/apache/htdocs/yf/$1
<Directory "/usr/local/apache/htdocs/yf">
Options none
AllowOverride none
Require all granted
</Directory>
</VirtualHost>
[root@LAMP htdocs]# pwd
/usr/local/apache/htdocs
[root@LAMP htdocs]# mkdir yf
[root@LAMP htdocs]# vim yf/index.php
[root@LAMP htdocs]# cat yf/index.php
<?php
phpinfo();
?>
[root@LAMP conf]# pwd
/usr/local/apache/conf
//搜索AddType，添加以下内容
[root@LAMP conf]# vim httpd.conf
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
[root@LAMP conf]# sed -i '/ DirectoryIndex/s/index.html/index.php index.html/g' /usr/local/apache/conf/httpd.conf
[root@LAMP conf]# systemctl restart httpd.service
4.3 验证
5.安装phpmyadmin
phpmyadmin下载地址
//下载phpmyadmin包
[root@LAMP ~]# wget https://files.phpmyadmin.net/phpMyAdmin/5.2.0/phpMyAdmin-5.2.0-all-languages.zip
//把该解压在网站的根目录
[root@LAMP ~]# mv phpMyAdmin-5.2.0-all-languages.zip /usr/local/apache/htdocs/yf/
[root@LAMP ~]# cd /usr/local/apache/htdocs/yf/
[root@LAMP yf]# unzip phpMyAdmin-5.2.0-all-languages.zip
//把目录的名字改为phpmyadmin
[root@LAMP yf]# mv phpMyAdmin-5.2.0-all-languages/ phpmyadmin
[root@LAMP yf]# cd phpmyadmin/
//复制样本配置文件到config.inc.php文件
[root@LAMP phpmyadmin]# cp config.sample.inc.php config.inc.php
[root@LAMP phpmyadmin]# systemctl restart httpd.service
