Centos7下安装Docker1.8

1.创建docker的yum库

[root@localhost~]# cd /etc/yum.repos.d/
[[email protected]]# 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.安装docker

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

3.关闭centos7下的firewalld服务并安装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.开启iptables服务

[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.启动docker服务并设置开机自动启动

[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.验证docker是否安装成功

[root@localhost~]# docker info

7.查看安装后的docker版本

[root@localhost~]# docker version
