【Docker】CentOS 系列安裝 Docker 步驟測試

第一次失敗安裝

[root@rosalie ~]# yum install docker

註:後發現此指令適用CentOS7

安裝好後測試出現錯誤訊息

[root@rosalie ~]# docker run centos:6.6 /bin/ps

Segmentation Fault or Critical Error encountered. Dumping core and aborting.

Aborted

確定有安裝但無法使用

[root@rosalie ~]# yum list installed |grep docker

docker.x86_64          1.5-5.el6        @epel  

直接卸載 

[root@rosalie ~]# yum -y remove docker.x86_64

第二次失敗安裝-沒任何事發生，又失敗

[root@rosalie ~]# yum install -y docker-io

..過程略

Error: Nothing to do

第三次安裝成功

先vi /etc/yum.repos.d/docker.repo

[root@rosalie ~]# vi /etc/yum.repos.d/docker.repo

直接I後加入如下内容：

[dockerrepo]

name=Docker Repository

baseurl=https://yum.dockerproject.org/repo/main/centos/$releasever/

enabled=1

gpgcheck=1

gpgkey=https://yum.dockerproject.org/gpg

然後再次安裝

[root@rosalie ~]# yum install docker-engine

啟動docker服務

[root@rosalie ~]# service docker start

出現

Starting cgconfig service:                                 [  OK  ]

Starting docker:                                       [  OK  ]

測試成功

[root@rosalie ~]#  docker run centos:6.6 /bin/ps
