WordPress是使用PHP語言開發的博客平台，用戶可以在支持PHP和MySQL數據庫的服務器上架設屬於自己的網站。也可以把 WordPress當作一個內容管理系統（CMS）來使用。
搭建WordPress 要分搭建php apache mysql 環境、配置數據庫、安裝WordPress
第一部分：搭建php apache mysql 環境，分開來搭建這些環境比較復雜，網絡上有現成的工具包類似一鍵安裝就能把環境搭建好，這個工具就是XAMPP 。這一部分步驟如下：
1、下載XAMPP ，下載地址：https://www.apachefriends.org/download.html 有windows、linux、macOS平台的可以下載。選擇適合自己的系統。我這里下載的是linux版本
2、執行下載文件：xampp-linux-x64-7.2.8-0-installer.run ，把下載文件上傳到centos服務器/opt 目錄下。執行命令： ./xampp-linux-x64-7.2.8-0-installer.run （如果安裝文件沒有可執行權限，執行命令chmod +x xampp-linux-x64-7.2.8-0-installer.run 賦給可執行權限）。在執行過程中會遇到確認提示，選擇y或者n，這里都選擇y。選擇完成后再和你確認安裝路徑安裝在：/opt/lampp 目錄下
[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、安裝xampp完成后，可以通過命令來啟動xampp環境
/opt/lampp/lampp start 啟動
/opt/lampp/lampp stop 停止
/opt/lampp/lampp restart 重啟
啟動后，可以通過ps -aef |grep lampp 來查看lampp 環境是否正常啟動。如下提示中，可以看出Apache 和MySQL都啟動正常
[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、關閉Centos7 防火牆命令：systemctl stop firewalld.service，關閉防火牆后，可以從外部訪問到這台服務器，到此，第一部分完成
第二部分：配置數據庫，數據庫服務在第一部分一鍵安裝好了，還需要配置下訪問權限
1、登錄mysql服務，執行命令：/opt/lampp/bin/mysql -uroot
2、登錄后執行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、登錄mysql 服務創建wordpress 數據庫，執行命令： /opt/lampp/bin/mysql -uroot -p 彈出輸入password ，輸入123456。登入后執行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.

第三部分：安裝Wordpress
1、下載Wordpress：https://wordpress.org/download/ 點擊Download .tar.gz 下載wordpress 壓縮包
2、解壓wordepress 到目錄/opt/lampp/htdocs/下：tar -xzvf wordpress-5.2.1.tar.gz -C /opt/lampp/htdocs/
3、瀏覽器中輸入http://192.168.1.108/wordpress/index.php ip 為centos7 的ip，由於是首次打開，自動跳轉到安裝頁面http://192.168.1.108/wordpress/wp-admin/setup-config.php
在安裝頁面，可以看出頁面提示的必要數據庫信息，這些信息在第二部分已經完成了
3、點擊 【Let‘s go’】 進入填寫數據庫信息頁面，點擊【submit】
4、如果點擊【Submit 】 按鈕后出現如下提示：
說明在寫wp-config.php 文件的時候沒有權限，提示中也給了解決方法，就是手動在wordpress 目錄下新建wp-config.php 文件，並且把提示中的代碼復制保存到wp-config.php 文件中再點擊【run the installation】就能繼續安裝
5、輸入站點信息，管理員賬號密碼后 點擊【Install WordPress】
6、安裝完成后，進入登錄頁：http://192.168.1.108/wordpress/wp-login.php，並登錄成功，說明安裝成功
