接著上次 磁盤滿了 需要清理系統(tǒng)盤
1，先用uname -a 查看當(dāng)前內(nèi)核版本:
uname -a
Linux 10-9-37-135 3.13.0-110-generic #157-Ubuntu SMP Mon Feb 20 11:54:05 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
版本是3.13.0-110
2，看一下當(dāng)前系統(tǒng)安裝的內(nèi)核版本:

太驚人了 竟然這么多 主要是年頭長，然后把不需要的都刪除就行
3，刪除多余的內(nèi)核
上面linux-headers、linux-image、linux-signed開頭的都是跟內(nèi)核相關(guān)的.帶有版本號的(如linux-image-extra-3.13.0-63-generic)才是可以刪除的.注意不要刪除當(dāng)前使用的版本.
sudo apt-get purge來刪除
sudo apt-get purge linux-image-extra-3.13.0-63-generic
sudo apt-get purge linux-signed-image-3.13.0-63-generic
sudo apt-get purge linux-headers-3.13.0-63(這個會自動把linux-headers-3.13.0-63-generic刪除)
注意
不要使用sudo apt-get remove來刪除,會出現(xiàn)linux-signed-image-3.13.0-63-generic deinstall
4，使用sudo update-grub更新啟動菜單
小結(jié)
內(nèi)核占用系統(tǒng)盤內(nèi)存比較大 /usr/src 雖然只有2.5G 但是實際清理完會有7個多G
