使用yum install docker安装完后启动不了

[root@apptest ~]# service docker start

docker: unrecognized service

一直停留在以上步骤 可以使用以下命令来安装，即可成功。 一个问题让我折腾了两天，试过关闭防火墙，关闭selinux，重装系统，等等网上能查到的方法都解决不了。 如果大家解决了，回复感谢下我吧。

[root@apptest ~]# yum remove docker

[root@apptest ~]# yum remove docker-selinux

[root@test yum.repos.d]# 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

[root@test yum.repos.d]# yum install docker-engine

已安装: docker-engine.x86_64 0:1.10.2-1.el7.centos

作为依赖被安装: docker-engine-selinux.noarch 0:1.10.2-1.el7.centos

[root@apptest ~]# service docker start

[root@test yum.repos.d]# 或者使用以下方法

[root@apptest ~]# curl -fsSL https://get.docker.com/ | sh + sh -c 'sleep 3;

yum -y -q install docker-engine'

Is the docker daemon running on this host? If you would like to use Docker as a non-root user, you should now consider adding your user to the "docker" group with something like: sudo usermod -aG docker your-user Remember that you will have to log out and back in for this to take effect! [root@apptest ~]#

[root@apptest ~]# service docker start Redirecting to /bin/systemctl start docker.service

[root@apptest ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE

[root@apptest ~]#
