systemctl disable swap-create.service swapoff /swapfile rm /swapfile sed -i '/.swap./d' /etc/fstab
日志可以缩减 journalctl --vacuum-size=100M
固定配置 echo SystemMaxUse=100M >> /etc/systemd/journald.conf systemctl restart systemd-journald
或者全部清掉 journalctl --vacuum-size=1K
及时删一下包缓存 apt clean all
/usr/share可以删掉，问题不大
