前言

在 RHEL 8 上當 Apache、MySQL 以及 PHP 等 LAMP 環境都已經安裝好了後，安裝 WordPress 也不遠了。本來想要先示範安裝 phpMyAdmin，然後使用 phpMyadmin 圖形化建立 WordPress 所使用的資料庫；但接連搜尋好幾篇文章，目前在 RHEL 8 環境下，都還沒有可以直接使用 rpm 或是 yum 的安裝方法，目前都還是需要解開壓縮檔、調整目錄並編輯設定的方式，步驟稍微繁瑣，因此就先跳過，繼續先使用下 SQL 語法的方式，建立 WordPress 所需的資料庫。

安裝

建立 WordPress 用的 MySQL 資料庫，隨後並進行檢測

$ mysql -u root -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \\g.
Your MySQL connection id is 8

下載 WordPress 安裝套件

$ cd /tmp/ && wget <https://tw.wordpress.org/wordpress-5.2.3-zh_TTW.tar.gz>

解壓縮 WordPress 套件，產生 WordPress 資料夾，將會被擺放到 /var/www/html/ 目錄底下

$ sudo tar -zxvf wordpress-5.2.3-zh_TW.tar.gz -C /var/www/html/

調整目錄擁有者

$ sudo chown -R apache :apache /var/www/html/wordpress/

調整 wordpress 資料夾的 SELinux 設定

$ sudo semanage fcontext -a -t httpd_sys_content_t '/var/www/hhtml/wordpress(/.*)?'
$ sudo restorecon -RFvv /var/www/html/wordpress
$ ls -aldZ /var/www/html/wordpress/
drwxr-xr-x. 5 apache apache system_u:object_r:httpd_sys_content_t:s0 4096 Sep  5 10:47 /var/www/html/wordpress/

為 WordPress 建立 Apache 的 Virtual Host

$ sudo vim /etc/httpd/conf.d/00-default-vhost.conf
#### 內容如下： ####
<Directory "/var/www/html">
    Require all granted
</Directory>

<VirtualHost _default_:80>
    ServerName    www.lab.example.com
    DocumentRoot  /var/www/html
    CustomLog     "logs/default-vhost.log" combined
</VirtualHost>

$ sudo vim /etc/httpd/conf.d/01-wordpress-vhost.conf
#### 內容如下： ####
<Directory "/var/www/html/wordpress">
    Require all granted
</Directory>

<VirtualHost *:80>
    ServerName    wordpress.lab.example.com
    DocumentRoot  /var/www/html/wordpress
    CustomLog     "logs/wordpress.log" combined
</VirtualHost>

重啟 Apache

$ sudo systemctl restart httpd

開啟瀏覽器，網址列輸入 http://wordpress.lab.example.com

輸入 WordPress 用的 MySQL 資料庫相關資訊

資料庫名稱：wordpress

使用者名稱：wordpress

密碼：W0rdPre$$

資料庫主機位址：localhost

資料表前置詞：wp_

哇！無法寫入檔案。有了上一次的經驗，這次比較不會緊張到不知所措了，只要 Follow 上面的提示去做即可。。

進到 /var/www/html/wordpress/ 目錄，新建 wp-config.php 檔案。把下面文字內容複製到 wp-config.php 後，存檔離開。

$ cd /var/www/html/wordpress/
$ ls
index.php        wp-blog-header.php    wp-includes        wp-settings.php
license.txt      wp-comments-post.php  wp-links-opml.php  wp-signup.php
readme.html      wp-config-sample.php  wp-load.php        wp-trackback.php
wp-activate.php  wp-content            wp-login.php       xmlrpc.php
wp-admin         wp-cron.php           wp-mail.php
$ sudo vim wp-config.php

完成後回來「執行安裝程式」。

輸入安裝網站所需資訊。接著安裝 WordPress。
