CentOs6和Centos7安裝docker

Centos6安裝的時候是按照網上的步驟，

yum install -y epel-release

yum install -y docker -io

service docker start

失敗了，說是未被識別的服務，接下來

yum remove docker

yum remove docker-io

vi  /etc/yum.repos.d/docker.repo

放入下面的內容

[dockerrepo]

name=Docker Repository

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

enabled=1

gpgcheck=1

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

 

---------------------------分割線---------------------------

 

yum install docker-engine

 

service docker start

ok，啟動成功

CentOs7安裝與CentOs6差不多，

有個答案是先移除安裝的和docker相關的東西

 

yum remove docker
yum remove docker-selinux

vi  /etc/yum.repos.d/docker.repo

[dockerrepo]

name=Docker Repository

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

enabled=1

gpgcheck=1

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

---------------------------分割線---------------------------

 

yum install docker-engine

 

service docker start

但是會報這樣的錯

[root@localhost ~]# service docker start
Redirecting to /bin/systemctl start docker.service
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details

我感覺應該是沒有卸載干凈，我是把虛擬機刪除重新導入，按照上面的方式安裝成功(如下)：

vi  /etc/yum.repos.d/docker.repo

放入下面的內容

[dockerrepo]

name=Docker Repository

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

enabled=1

gpgcheck=1

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

 

---------------------------分割線---------------------------

 

yum install docker-engine

 

service docker start
