WordPress是使用PHP语言开发的博客平台，用户可以在支持PHP和MySQL数据库的服务器上架设属于自己的网站。也可以把 WordPress当作一个内容管理系统（CMS）来使用。
搭建WordPress 要分搭建php apache mysql 环境、配置数据库、安装WordPress
第一部分：搭建php apache mysql 环境，分开来搭建这些环境比较复杂，网络上有现成的工具包类似一键安装就能把环境搭建好，这个工具就是XAMPP 。这一部分步骤如下：
1、下载XAMPP ，下载地址：https://www.apachefriends.org/download.html 有windows、linux、macOS平台的可以下载。选择适合自己的系统。我这里下载的是linux版本
2、执行下载文件：xampp-linux-x64-7.2.8-0-installer.run ，把下载文件上传到centos服务器/opt 目录下。执行命令： ./xampp-linux-x64-7.2.8-0-installer.run （如果安装文件没有可执行权限，执行命令chmod +x xampp-linux-x64-7.2.8-0-installer.run 赋给可执行权限）。在执行过程中会遇到确认提示，选择y或者n，这里都选择y。选择完成后再和你确认安装路径安装在：/opt/lampp 目录下
[root@bogon opt]# pwd /opt [root@bogon opt]# ls xampp-linux-x64-7.2.8-0-installer.run [root@bogon opt]# ./xampp-linux-x64-7.2.8-0-installer.run ---------------------------------------------------------------------------- Welcome to the XAMPP Setup Wizard. ---------------------------------------------------------------------------- Select the components you want to install; clear the components you do not want to install. Click Next when you are ready to continue. XAMPP Core Files : Y (Cannot be edited) XAMPP Developer Files [Y/n] :y Is the selection above correct? [Y/n]: y ---------------------------------------------------------------------------- Installation Directory XAMPP will be installed to /opt/lampp Press [Enter] to continue: ---------------------------------------------------------------------------- Setup is now ready to begin installing XAMPP on your computer. Do you want to continue? [Y/n]: y ---------------------------------------------------------------------------- Please wait while Setup installs XAMPP on your computer. Installing 0% ______________ 50% ______________ 100% ######################################### ---------------------------------------------------------------------------- Setup has finished installing XAMPP on your computer. [root@bogon opt]#
3、安装xampp完成后，可以通过命令来启动xampp环境
/opt/lampp/lampp start 启动
/opt/lampp/lampp stop 停止
/opt/lampp/lampp restart 重启
启动后，可以通过ps -aef |grep lampp 来查看lampp 环境是否正常启动。如下提示中，可以看出Apache 和MySQL都启动正常
[root@bogon opt]# /opt/lampp/lampp stop Stopping XAMPP for Linux 7.2.8-0... XAMPP: Stopping Apache...ok. XAMPP: Stopping MySQL...ok. XAMPP: Stopping ProFTPD...not running. [root@bogon opt]# /opt/lampp/lampp start Starting XAMPP for Linux 7.2.8-0... XAMPP: Starting Apache...ok. XAMPP: Starting MySQL...ok. XAMPP: Starting ProFTPD...fail.

4、关闭Centos7 防火墙命令：systemctl stop firewalld.service，关闭防火墙后，可以从外部访问到这台服务器，到此，第一部分完成
第二部分：配置数据库，数据库服务在第一部分一键安装好了，还需要配置下访问权限
1、登录mysql服务，执行命令：/opt/lampp/bin/mysql -uroot
2、登录后执行SQL
use mysql; select t.host from user t where t.user='root'; GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION; GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY '123456' WITH GRANT OPTION; FLUSH PRIVILEGES;
[root@bogon opt]# /opt/lampp/bin/mysql -uroot Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 3 Server version: 10.1.34-MariaDB Source distribution 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)]> use mysql; Database changed MariaDB [mysql]> select t.host from user t where t.user='root'; +-----------+ | host | +-----------+ | 127.0.0.1 | | ::1 | | localhost | +-----------+ 3 rows in set (0.00 sec) MariaDB [mysql]> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION; Query OK, 0 rows affected (0.00 sec) MariaDB [mysql]> GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY '123456' WITH GRANT OPTION; Query OK, 0 rows affected (0.01 sec) MariaDB [mysql]> FLUSH PRIVILEGES; Query OK, 0 rows affected (0.00 sec) MariaDB [mysql]>
3、登录mysql 服务创建wordpress 数据库，执行命令： /opt/lampp/bin/mysql -uroot -p 弹出输入password ，输入123456。登入后执行SQL：CREATE DATABASE IF NOT EXISTS wordpress DEFAULT CHARSET utf8 COLLATE utf8_general_ci;
[root@bogon opt]# /opt/lampp/bin/mysql -uroot -p Enter password: Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 5 Server version: 10.1.34-MariaDB Source distribution Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

第三部分：安装Wordpress
1、下载Wordpress：https://wordpress.org/download/ 点击Download .tar.gz 下载wordpress 压缩包
2、解压wordepress 到目录/opt/lampp/htdocs/下：tar -xzvf wordpress-5.2.1.tar.gz -C /opt/lampp/htdocs/
3、浏览器中输入http://192.168.1.108/wordpress/index.php ip 为centos7 的ip，由于是首次打开，自动跳转到安装页面http://192.168.1.108/wordpress/wp-admin/setup-config.php
在安装页面，可以看出页面提示的必要数据库信息，这些信息在第二部分已经完成了
3、点击 【Let‘s go’】 进入填写数据库信息页面，点击【submit】
4、如果点击【Submit 】 按钮后出现如下提示：
说明在写wp-config.php 文件的时候没有权限，提示中也给了解决方法，就是手动在wordpress 目录下新建wp-config.php 文件，并且把提示中的代码复制保存到wp-config.php 文件中再点击【run the installation】就能继续安装
5、输入站点信息，管理员账号密码后 点击【Install WordPress】
6、安装完成后，进入登录页：http://192.168.1.108/wordpress/wp-login.php，并登录成功，说明安装成功
