Ubuntu 14.04.2 LTS \n \l

內核版本號

uname -r

3.16.0-30-generic

相比阿里雲，提供3.8.0-44-generic  的內核，ubuntu12。在360雲就會好很是多了，

備註

Docker is supported on these Ubuntuoperating systems:

• Ubuntu Vivid 15.04

• Ubuntu Trusty 14.04 (LTS)

• Ubuntu Precise 12.04 (LTS)

• Ubuntu Saucy 13.10

  Kernels older than 3.10 lack some of thefeatures required to run Docker containers. These older versions are known tohave bugs which cause data loss and frequently panic under certain conditions.

  假設Kenerl版本號小於3.10，那麼對docker的支持就會打折扣，甚至執行問題，在阿里雲或者您選擇較低版本號的系統，需要對內核進行升級。話說這年頭，程序猿何苦爲難程序猿，直接選擇最新版本號安裝。

  Do you want to continue? [Y/n]

  aufs-toolscgroup-lite git git-manliberror-perl docker.io 這六個就是安裝項目。看一下fs這個必須得

   

  安裝完成檢查執行狀態，因爲這個是自啓動的：

  service docker.io status

  docker.io start/running, process 2711

  這時候。建議把pid刪除

  Cd /var/run

  Rm –f docker.pid

  又一次啓動docker –d

   

  新開一個Terminal。而後可以操做docker了
