# 在Ubuntu 22.04上面使用LAMP系統設定Wordpress
LAMP= Linux, Apache, MySQL, PHP

1. 系統更新 & 安裝 Apache以及設定防火牆

$ sudo apt update

然後安裝Apache

$ sudo apt install apache2

使用UFW來設定防火牆

$ sudo ufw app list
$ sudo ufw allow in "Apache Secure"

2. 使用Certbot安裝&設定自動更新Let's Encrypt憑證

$ sudo snap install --classic certbot
$ sudo ln -s /snap/bin/certbot /usr/bin/certbot
$ sudo certbot --apache
$ sudo certbot renew --dry-run #安裝完成後測試是否自動更新有正常運作

3. 安裝MySQL

$ sudo apt install mysql-server
$ sudo mysql_secure_installation

4. 安裝PHP

$ sudo apt install php libapache2-mod-php php-mysql
$ php -v

5. 新增Database & User讓WordPress使用

$ sudo mysql

mysql> CREATE DATABASE wordpress DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci;
mysql >CREATE USER 'wordpressuser'@'%' IDENTIFIED WITH mysql_native_password BY '密碼'; 
mysql> GRANT ALL ON wordpress.* TO 'wordpressuser'@'%';
mysql> FLUSH PRIVILEGES;
mysql>EXIT;

6. 安裝額外會用到的PHP套件

sudo apt update
sudo apt install php-curl php-gd php-mbstring php-xml php-xmlrpc php-soap php-intl php-zip
sudo systemctl restart apache2

7. 設定Apache設定.htaccess權限

sudo nano /etc/apache2/sites-available/這邊要看預設是哪個.conf

將設定插入檔案當中

<VirtualHost *:80>
. . .
    ServerName 這邊記得要修改
    <Directory /var/www/wordpress/>
        AllowOverride All
    </Directory>
. . .
</VirtualHost>

sudo a2enmod rewrite
sudo apache2ctl configtest

8. 下載WordPress

cd /tmp
curl -O https://wordpress.org/latest.tar.gz
tar xzvf latest.tar.gz
touch /tmp/wordpress/.htaccess
cp /tmp/wordpress/wp-config-sample.php /tmp/wordpress/wp-config.php
mkdir /tmp/wordpress/wp-content/upgrade
sudo cp -a /tmp/wordpress/. /var/www/wordpress

9. 設定WordPress資料夾路徑

sudo chown -R www-data:www-data /var/www/wordpress
sudo find /var/www/wordpress/ -type d -exec chmod 750 {} \;
sudo find /var/www/wordpress/ -type f -exec chmod 640 {} \;
curl -s https://api.wordpress.org/secret-key/1.1/salt/ 
#把回傳的訊息複製起來貼到wp-config.php
sudo nano /var/www/wordpress/wp-config.php #貼到這裡面

裡面其他地方也要修正
