Docker1.8在Centos7下的安裝

1.建立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服務並安裝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）開啓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）啓動docker服務並設置開機自動啓動

[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
