安裝ubuntu的時候採用的是lvm方式自動安裝的，劃分的swap分割槽太小了，無法滿足安裝oracle的要求,下面單獨建立一個交換分割槽
fallocate -l 4G /swapfile
ls -lh /swapfile
chmod 600 /swapfile
mkswap /swapfile
swapon /swapfile
swapon --show
echo '/swapfile none swap sw 0 0' | tee -a /etc/fstab
註釋掉之前分配太小的

# that works even if disks are added and removed. See fstab(5).
