LAMP服务架构
文章目录
1. LAMP简介
2. LAMP工作原理
当客户端请求的是静态资源时，web服务（httpd程序），会直接返回静态资源给客户端
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
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
最终php程序将解析后的结果返回给apache（httpd程序），让apache返回给客户端

3. 部署LAMP
3.1 源码安装http服务
# 下载解压包后解压
[root@localhost ~]# ls
anaconda-ks.cfg apr-1.7.0.tar.gz apr-util-1.6.1.tar.gz httpd-2.4.53.tar.gz
[root@localhost ~]# tar -xf apr-1.7.0.tar.gz
[root@localhost ~]# tar -xf apr-util-1.6.1.tar.gz
[root@localhost ~]# tar -xf httpd-2.4.53.tar.gz
# 安装环境
[root@localhost ~]# dnf -y group mark install "Development Tools"
[root@localhost ~]# dnf -y install gcc gcc-c++ openssl-devel pcre-devel expat-devel
# 创建用户
[root@localhost ~]# useradd -r -M -s /sbin/nologin apache
# 编译安装
[root@localhost ~]# cd apr-1.7.0
