linux搭建简单的LAMP服务架构

LAMP：Linux ---- Apache ---- MariaDB / MySQL ---- PHP / Python 

Linux 服务管理：

systemctl start        //开启服务
systemctl stop        //停止服务
systemctl reload     //重新加载
systemctl restart    //重启服务 
systemctl status     //查看服务运行状态
systemctl enable    //设置开机自启
systemctl disble     //禁止开机启动

--------------------------------------------------------

LAMP安装及启用：基于Linux主机快速构建LAMP动态网站平台，并启用相关系统服务

1)安装LAMP平台各组件
安装： yum -y install httpd mariadb-server mariadb php php-mysql
确认结果：yum list httpd mariadb-server mariadb php php-mysql

2)启用LAMP网站平台：

启动数据库：systemctl start mariadb
-->设置开机启动： systemctl enable mariadb

开启服务： systemctl restart httpd

设置开机自启：systemctl enable httpd mariadb

关闭防火墙： systemctl stop firewalld

设置开机不启动防火墙： systemctl disable firewalld

关闭SELinux保护机制：
 　   setenforce 0 #临时关闭
　　vim /etc/selinux/config #永久关闭  ：SELINUX=disabled

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled  #修改为disabled
# SELINUXTYPE= can take one of three two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected. 
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

测试LAMP网站平台

[root@svr7 ~]# vim  /var/www/html/test1.php

<?php
phpinfo();  //用来显示PHP环境信息
?>

测试PHP访问数据库

本机的mariadb数据库服务未做配置时，管理员账号为root、密码为空。

[root@svr7 ~]# vim  /var/www/html/test2.php

<?php
    $link=mysql_connect('localhost','root','');
    if($link) echo "Success !!";                 //成功则显示 Success !!
    else echo "Failure !!";                     //失败则显示 Failure !!
    mysql_close();                              //关闭数据库连接
?>
