linux——boot空间不足

1. 先用df命令，查看磁盘分区情况

2. dpkg --get-selections|grep linux-image（查看更新了多少内核）

 

root@ubuntu:/home/hadoop# dpkg --get-selections|grep linux-image
linux-image-4.4.0-31-generic			install
linux-image-4.4.0-34-generic			install
linux-image-4.4.0-36-generic			install
linux-image-4.4.0-45-generic			install
linux-image-4.4.0-59-generic			install
linux-image-4.4.0-66-generic			install
linux-image-4.4.0-70-generic			install
linux-image-extra-4.4.0-31-generic		install
linux-image-extra-4.4.0-34-generic		install
linux-image-extra-4.4.0-36-generic		install
linux-image-extra-4.4.0-45-generic		install
linux-image-extra-4.4.0-59-generic		install
linux-image-extra-4.4.0-66-generic		install
linux-image-extra-4.4.0-70-generic		install
linux-image-generic				install

 

 3. uname -a（查看当前运行的内核）

root@ubuntu:/home/hadoop# uname -a
Linux ubuntu 4.4.0-70-generic #91-Ubuntu SMP Wed Mar 22 12:46:53 UTC 2017 i686 i686 i686 GNU/Linux

 4. 删除不用的内核

root@ubuntu:/home/hadoop# apt-get autoremove linux-image-4.4.0-31-generic linux-image-4.4.0-34-generic linux-image-4.4.0-36-generic linux-image-4.4.0-45-generic linux-image-4.4.0-59-generic linux-image-4.4.0-66-generic
