1.創建docker的yum庫

[root@localhost~]# cd /etc/yum.repos.d/

[root@localhostyum.repos.d]# vim docker.repo

[dockerrepo]

name=DockerRepository

baseurl=https://yum.dockerproject.org/repo/main/centos/7

enabled=1

gpgcheck=1

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

（2）安裝docker

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

?

（3）關閉centos7下的firewalld服務并安裝iptables-ser

?

[root@localhost~]# systemctl disable firewalld

rm'/etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service'

rm'/etc/systemd/system/basic.target.wants/firewalld.service'

[root@localhost~]# yum -y install iptables-services

?

（4）開啟iptables服務

[root@localhost~]# systemctl enable iptables

ln-s '/usr/lib/systemd/system/iptables.service''/etc/systemd/system/basic.target.wants/iptables.service'

[root@localhost~]# systemctl start iptables

?

（5）啟動docker服務并設置開機自動啟動

[root@localhost~]# systemctl start docker.service

[root@localhost~]# systemctl enable docker.service

ln-s '/usr/lib/systemd/system/docker.service''/etc/systemd/system/multi-user.target.wants/docker.service'

?

（6）驗證docker是否安裝成功

[root@localhost~]# docker info

?

（8）查看安裝后的docker版本

[root@localhost~]# docker version

?Version:?????1.8.2

?API version:?1.20
