Docker学习笔记04：Docker安装

说明：这里只介绍rpm的安装方式，出于工作需要，不能连接外网；其它一些安装方式，请大家自行选择。

 安装版本：docker-engine-1.7.1-1.el6.x86_64.rpm。

操作步骤：

1. 将上面的docker安装包，上传到服务器的/root下；

2. 安装docker：

[root@test ~]# yum install –y docker-engine-1.7.1-1.el6.x86_64.rpm
或者
[root@test ~]# rpm -ivh docker-engine-1.7.1-1.el6.x86_64.rpm

我用上面两种方式都试过，没问题的。

3. 验证docker是否安装成功：

[root@test ~]#service docker start
[root@test ~]# docker version 
Client:

 知识扩展：

1. docker加入开机自启：

[root@test ~]#chkconfig docker on    --加入
[root@test ~]#chkconfig --list docker  --查看

2. 授权非root用户使用docker

[root@test ~]#gpasswd -a test docker
[root@test ~]#usermod -a -G docker test 
切换到test用户下
[test@test ~]$service docker restart
[test@test ~]$docker version

 

至此，docker安装完成。
