1. 安裝小工具

   $ sudo yum install vim wget -y
   

2. 安裝 SELinux 相關工具

   $ sudo yum install policycoreutils-python -y
   

3. 安裝 PHP 相關模組

   $ sudo yum install php-mysqlnd -y
   

4. 建立 WordPress 用的 MariaDB 資料庫

   Enter password:
   Welcome to the MariaDB monitor.  Commands end with ; or \g.
   Your MariaDB connection id is 10
   Server version: 5.5.60-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@localhost identified by 'password';
   Query OK, 0 rows affected (0.00 sec)
   
   MariaDB [(none)]> grant all on wordpress.* to wordpress@localhost;
   Query OK, 0 rows affected (0.00 sec)
   
   MariaDB [(none)]> flush privileges;
   Query OK, 0 rows affected (0.00 sec)
   
   MariaDB [(none)]> show databases;
   +--------------------+
   | Database           |
   +--------------------+
   | information_schema |
   | mysql              |
   | performance_schema |
   | wordpress          |
   +--------------------+
   4 rows in set (0.00 sec)
   
   MariaDB [(none)]> use mysql;
   Reading table information for completion of table and column names
   You can turn off this feature to get a quicker startup with -A
   
   Database changed
   MariaDB [mysql]> select host, user, password from user where user='wordpress';
   +-----------+-----------+-------------------------------------------+
   | host      | user      | password                                  |
   +-----------+-----------+-------------------------------------------+
   | localhost | wordpress | *2470C0C06DEE42FD1618BB99005ADCA2EC9D1E19 |
   +-----------+-----------+-------------------------------------------+
   1 row in set (0.01 sec)
   
   MariaDB [mysql]> show grants for wordpress@localhost;
   +------------------------------------------------------------------------------------------------------------------+
   | Grants for wordpress@localhost                                                                                   |
   +------------------------------------------------------------------------------------------------------------------+
   | GRANT USAGE ON *.* TO 'wordpress'@'localhost' IDENTIFIED BY PASSWORD  '*2470C0C06DEE42FD1618BB99005ADCA2EC9D1E19' |
   | GRANT ALL PRIVILEGES ON `wordpress`.* TO 'wordpress'@'localhost'                                                 |
   +------------------------------------------------------------------------------------------------------------------+
   2 rows in set (0.00 sec)
   
   MariaDB [mysql]> exit
   Bye
   

5. 下載 WordPress 安裝套件

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

6. 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/
   

7. 調整目錄擁有者

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

8. 調整 wordpress 資料夾的 SELinux 設定

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

9. 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
       ServerAlias   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
       ServerAlias   wordpress
       DocumentRoot  /var/www/html/wordpress
       CustomLog     "logs/wordpress.log" combined
   </VirtualHost>
   

10. 重啟 Apache

$ sudo systemctl restart httpd

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

    

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

    

明日待續……
