LNMP项目实战环境说明

L：Linux（CentOS7）https://mirrors.aliyun.com/centos/7/isos/x86_64/
N：Nginx（1.18.0） https://nginx.org/en/download.html
M：MySQL（8.0.19） https://dev.mysql.com/downloads/mysql/
P：PHP（7.4.10） http://php.net/downloads.php
Wordpress（5.4.2）：https://cn.wordpress.org/download/

#部署规划：
192.168.26.201：Nginx php-fpm 运行web服务
192.168.26.202：运行MySQL数据库

1.1 部署数据库

在192.168.26.202主机部署MySQL服务

1.1.1 部署Mariadb数据库

1  [root@mariadb ~]# yum -y install mariadb-server
2  [root@mariadb ~]# systemctl enable --now mariadb.service

1.1.2 创建wordpress数据库和用户并授权

[root@mariadb ~]# mysql

Welcome to the MariaDB monitor.  Commands end with ; or \g.

Your MariaDB connection id is 2

Server version: 5.5.68-MariaDB MariaDB Server
Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]> create database wordpress;
Query OK, 1 row affected (0.00 sec) 
 MariaDB [(none)]> create user wordpress@'192.168.26.%' identified by '123456';

Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> grant all on wordpress.* to wordpress@'192.168.26.%';

Query OK, 0 rows affected (0.00 sec) 18

MariaDB [(none)]>

1.1.3 验证MySQL账户权限

在WordPress服务器使用授权的MySQL账户远程登录测试权限

[root@web ~]# mysql -uwordpress -p123456 -h192.168.26.202
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
+--------------------+
| Database            |
+--------------------+
| information_schema |
| test                 |
| wordpress          |
+--------------------+
3 rows in set (0.00 sec)

1.2 部署PHP

在192.168.26.201主机部署php-fpm服务

1.2.1 编译安装 php

https://www.php.net/downloads.php
