OCI Cloud Free Tier をもぎ取れ その13

概要

OCI Cloud Free Tierを取得してみた。
asdfでコンパイルが始まるとwebが動かなくなる対策。

手順

freeで確認。

$ free -h
			   total		used		free	  shared  buff/cache   available
Mem:		   958Mi	   236Mi	   128Mi	   1.0Mi	   593Mi	   574Mi
Swap:			 0B		  0B		  0B

swapfileを設定。

$ sudo fallocate -l 1G /swapfile

$ sudo chmod 600 /swapfile

$ sudo mkswap /swapfile
Setting up swapspace version 1, size = 1024 MiB (1073737728 bytes)
no label, UUID=9a9a2ade-54a1-4a22-bedb-0cc0120c8a24

$ sudo swapon /swapfile

$ free -h
               total        used        free      shared  buff/cache   available
