# 1. 创建 1GB 的 swap 文件
sudo fallocate -l 1G /swapfile
# 若提示 fallocate 不支持，可改用：
# sudo dd if=/dev/zero of=/swapfile bs=1M count=1024 status=progress

# 2. 设置权限（必须 600）
sudo chmod 600 /swapfile

# 3. 格式化为 swap 类型
sudo mkswap /swapfile

# 4. 启用 swap
sudo swapon /swapfile

# 5. 验证启用情况
sudo swapon --show
free -h

# 6. 设置开机自动挂载（带备份）
sudo cp /etc/fstab /etc/fstab.bak
echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
