CentOs6和Centos7安装docker

Posted 2021-11-28 java-jiangtao-home

Centos6安装的时候是按照网上的步骤，

yum install -y epel-release

yum install -y docker -io

service docker start

失败了，说是未被识别的服务，接下来

yum remove docker

yum remove docker-io

vi  /etc/yum.repos.d/docker.repo

放入下面的内容

[dockerrepo]

name=Docker Repository

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

enabled=1

gpgcheck=1

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

 

---------------------------分割线---------------------------

 

yum install docker-engine

 

service docker start

ok，启动成功

CentOs7安装与CentOs6差不多，

有个答案是先移除安装的和docker相关的东西

 

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

---------------------------分割线---------------------------

 

yum install docker-engine

 

service docker start

但是会报这样的错

[[email protected] ~]# 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

我感觉应该是没有卸载干净，我是把虚拟机删除重新导入，按照上面的方式安装成功(如下)：

vi  /etc/yum.repos.d/docker.repo

放入下面的内容

[dockerrepo]

name=Docker Repository

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

enabled=1

gpgcheck=1

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

 

---------------------------分割线---------------------------

 

yum install docker-engine

 

service docker start
