CentOS7 添加 Swap
目录
cd /
fallocate -l 1G swapfile
chmod 600 swapfile
mkswap swapfile
swapon swapfile
如果执行 swapon 的时候,提示 swapon failed: Invalid argument
则把 fallocate -l 2G swapfile
替换为 dd if=/dev/zero of=/swapfile count=4096 bs=1MiB
cd /
dd if=/dev/zero of=/swapfile count=1024 bs=1MiB
chmod 600 swapfile
mkswap swapfile
swapon swapfile
