CREATE DATABASE wp_production CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

CREATE USER 'wp_user'@'localhost' IDENTIFIED BY 'STRONG_SECRET_PASS_2026';

# 1. 创建网站目标目录并下载官方源码

mkdir -p /var/www/yourdomain.com && cd /tmp

wget https://wordpress.org/latest.tar.gz

tar -xzf latest.tar.gz && cp -r wordpress/* /var/www/yourdomain.com/

# 2. 赋予 www-data 用户所有权，并将目录设为 755，文件设为 644

chown -R www-data:www-data /var/www/yourdomain.com

find /var/www/yourdomain.com/ -type d -exec chmod 755 {} \;

find /var/www/yourdomain.com/ -type f -exec chmod 644 {} \;
