LAMP环境搭建

LAMP环境搭建

一、什么是LAMP环境？

在中小型公司当中，要想让公司的网站迅速上线，就会采用到LAMP环境。那什么是LAMP环境呢？我们先说一下网站上边数据的构成，网站中数据由两种组成，一种是静态数据，一种是动态数据。

静态数据：每一个用户看到的相同的数据（比如：网页上的图片，动画，文字等），一般由html，css，jsp，php等静态语言编写。动态数据：每一个用户得到不一样的数据（比如，用户的个人信息，密码，照片，文件等），一般是由中间件去调用后端数据库去得到。

所以，我们构建一个简单的网站一般会有三部分组成，运行静态语言的web服务，关系型数据库服务，和网站代码。

LAMP = Linux + Apache + Mysql + PHP

也就是说：LAMP环境就是在Linux平台上使用Apache（http）服务运行PHP静态语言写成的web代码，用户的数据放在后端的Mysql数据库当中

二、环境准备

由于是实验环境，我们就不去自己写一个PHP代码了，我们直接借用一个开源的博客系统wordpress，然后将其代码放在http服务的工作目录下

wordpress的下载路径为：https://wordpress.org/download/

Linux平台环境：test1  192.168.1.41

三、软件安装

[root@test1 ~]# yum -y install php php-mysql mariadb-server httpd

php:提供php运行环境php-mysql：连接php和mysql的工具mariadb-server：数据库，存放PHP环境运行时的数据httpd：为用户提供web界面

四、配置wordpress

[root@test1 ~]# tar -zxvf wordpress-4.6.13.tar.gz[root@test1 ~]# cp -rvf wordpress/* var/www/html/[root@test1 ~]# cd var/www/html/[root@test1 html]# mv wp-config-sample.php wp-config.php[root@test1 html]# vim wp-config.phpdefine('DB_NAME', 'wordpress');define('DB_USER', 'wordpress');define('DB_PASSWORD', 'wordpresspwd');define('DB_HOST', 'localhost');

define('DB_NAME', 'wordpress');            #代表wordpress去连接数据库的库名

define('DB_USER', 'wordpress');            #代表wordpress去连接数据库的用户名

define('DB_PASSWORD', 'wordpresspwd');            #代表wordpress去连接数据库的用户名的密码

define('DB_HOST', 'localhost');            #代表wordpress去连接数据库的地址

五、配置mysql

[root@test1 ~]# systemctl start mariadb[root@test1 ~]# mysql_secure_installation Enter current password for root (enter for none): OK, successfully used password, moving on...Setting the root password ensures that nobody can log into the MariaDBroot user without the proper authorisation.Set root password? [Y/n] yNew password: Re-enter new password: Password updated successfully!Reloading privilege tables.. ... Success!By default, a MariaDB installation has an anonymous user, allowing anyoneto log into MariaDB without having to have a user account created forthem. This is intended only for testing, and to make the installationgo a bit smoother. You should remove them before moving into aproduction environment.Remove anonymous users? [Y/n] y ... Success!Normally, root should only be allowed to connect from 'localhost'. Thisensures that someone cannot guess at the root password from the network.Disallow root login remotely? [Y/n] n ... skipping.By default, MariaDB comes with a database named 'test' that anyone canaccess. This is also intended only for testing, and should be removedbefore moving into a production environment.Remove test database and access to it? [Y/n] y - Dropping test database... ... Success! - Removing privileges on test database... ... Success!Reloading the privilege tables will ensure that all changes made so farwill take effect immediately.Reload privilege tables now? [Y/n] y ... Success!Cleaning up...All done! If you've completed all of the above steps, your MariaDBinstallation should now be secure.Thanks for using MariaDB![root@test1 ~]# mysql -uroot -p000000MariaDB [(none)]> create database wordpress;Query OK, 1 row affected (0.00 sec)MariaDB [(none)]> create user wordpress@'%' identified by 'wordpresspwd';Query OK, 0 rows affected (0.00 sec)MariaDB [(none)]> grant all on wordpress.* to wordpress@'%' identified by 'wordpresspwd';Query OK, 0 rows affected (0.00 sec)

1、启动mysql

2、初始化数据库

3、创建数据库wordpress

4、创建数据库用户wordpress

5、赋予用户wordpress对库wordpress操作的所以权限

六、启动http并验证

[root@test1 ~]# systemctl start httpd
