# RAM / Swap Space# Between GB and GB / 1.5 times the size of the RAM
# Between GB and GB / Equal to the size of the RAM
# More than GB / GB
# 執行如下命令
# 然後，檢查和設定swap那一行是否有被註釋，如果被註釋就要開啟
cat /etc/fstab
# 檢視swap 空間大小(總計)：
free -m
# 檢視swap 空間(file(s)/partition(s))：
swapon -s # 檢視磁碟路徑的空間
df -h /home # 關閉所有的swap空間swapoff -a # 建立新的swap檔案，bs=表示每個block分塊大小是1024 byte，count表示多少個block分塊，所以總大小是bs*count=4GB
dd if=/dev/zero of=/home/system-swap bs= count=
# 輸出如下
# + records in
# + records out
# bytes (4.3 GB) copied, 29.991 s, MB/s # 設定這個分割槽的許可權為600
chmod -R /home/system-swap # 把這個新建分割槽，變成swap分割槽
/sbin/mkswap /home/system-swap
# 輸出如下
# Setting up swapspace version , size = KiB
# no label, UUID=941e36a8-d389--ad7d-07387e1da776 # 把這個新建分割槽，設定狀態為open。
# 備註：重啟之後，該swap分割槽還是失效，只有執行下面配置後才會永久生效。
/sbin/swapon /home/system-swap # 設定重啟後，swap分割槽仍然有效
# 編輯如下檔案，修改swap行內容為新加分割槽/home/system-swap
