linux-LAMP搭建

LAMP

1.架构描述

LAMP是一个C/S架构的平台：web客户端基于tcp/ip协议，发出http请求，服务端进行回应，用户的请求可能是动态的也可能是静态的。

web服务器通过用户发送的url后缀判断动静态请求：

• 静态请求web服务器直接处理
• 静态请求web服务器转发给后台应用服务器去处理：(CGI)php运行的后台程序

apache与php所处环境不同决定其通讯方式不同：

• 安装在同一台服务器，就默认使用系统共享内存通信
• 按装在不同服务器，就通过网络，进行socket网络套接字通信

2.搭建

关闭防火墙，关闭selinux

1.安装Apache

[root@localhost ~]# yum install httpd -y
[root@localhost ~]# systemctl enable --now httpd
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.

[root@localhost ~]# cat > /var/www/html/index.html <
> <meta charset=utf8>
> 一起来学LAMP
> EOF

2.yum安装mariadb（mysql）

[root@localhost ~]# yum install mariadb-server mariadb -y
[root@localhost ~]# systemctl enable --now mariadb
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.

[root@localhost ~]# netstat -tunlp |grep mysql
tcp        0      0 0.0.0.0:3306            0.0.0.0:*               LISTEN      11026/mysqld     

登录：
[root@localhost ~]# mysql -uroot -p
