CentOS 7.2 安裝 Docker 1.12.3 版

本文出自http://www.cnblogs.com/scoter2008

1、強大的官方文檔

https://docs.docker.com/engine/installation/linux/centos/

2、按步驟來，先更新yum源，這裡用163的源

yum install -y wget
cd /etc/yum.repos.d
wget http://mirrors.163.com/.help/CentOS7-Base-163.repo
/usr/bin/yum clean all
/usr/bin/yum makecache
其他系統自帶的源可以保留，也可以全部幹掉

3、更新系統

yum update

4、如果遇到問題：Delta RPMs disabled because /usr/bin/applydeltarpm not installed.

yum install -y deltarpm

5、編輯生成docker的yum源文件

tee /etc/yum.repos.d/docker.repo <<-'EOF'
[dockerrepo]
name=Docker Repository
baseurl=https://yum.dockerproject.org/repo/main/centos/7/
enabled=1
gpgcheck=1
gpgkey=https://yum.dockerproject.org/gpg
EOF

6、安裝Docker

yum install docker-engine

7、如果遇到問題：Public key for docker-engine-selinux-1.10.1-1.el7.centos.noarch.rpm is not installed，執行下麵的命令

rpm --import https://yum.dockerproject.org/gpg

8、Docker下載速度很慢，請耐心等待

9、安裝完成後設置開機自啟

systemctl enable docker.service

10、啟動docker守護進程

systemctl start docker

11、查看docker版本

[root@localhost ~]# docker version
Client:
 Version:      1.12.3
 API version:  1.24
 Go version:   go1.6.3
 Git commit:   6b644ec

12、 Done，enjoy it!
