# 备份原有数据库
mysqldump -u username -p old_database > old_database_backup.sql

# 恢复到新数据库
mysql -u username -p new_database < old_database_backup.sql

# 检查域名解析
nslookup newdomain.com

# 刷新DNS缓存
sudo systemd-resolve --flush-caches

# 安装新的SSL证书
sudo cp new_certificate.crt /etc/letsencrypt/live/newdomain.com/fullchain.pem
sudo cp new_private_key.key /etc/letsencrypt/live/newdomain.com/privkey.pem

# 更新Nginx配置
server {
    listen 443 ssl;
    server_name newdomain.com;

    ssl_certificate /etc/letsencrypt/live/newdomain.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/newdomain.com/privkey.pem;

    location / {
        root /var/www/newdomain;
        index index.html index.htm;
    }
}
