# Linux-增加Swap方法

**如何增加swap空间？**

```bash
# 例如添加是swap空间路径 /data/swap, bs是每块的大小，count是块的数量；bs*count，就是swap文件的大小：这里1M*1024=1G。可以根据需要自行调整
dd if=/dev/zero of=/data/swap bs=1M count=1024
mkswap /data/swap
chmod 0600 /data/swap -R
swapon /data/swap

# 开机自启动
echo "/data/swap swap swap defaults 0 0" >> /etc/fstab
```
