内核要求至少 3.8.0版本或以上. https://docs.docker.com/linux/


wget http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
sudo rpm -Uvh epel-release-6-8.noarch.rpm

此时,会在/etc/yum.repo.d/目录里生成两个文件epel.repo  epel-testing.repo.



这里我用的centos7.0 x64的系统。

安装前需要安装相对应的epel库,我用的 Centos 7.0的系统。

$ wget http://ftp.sjtu.edu.cn/fedora/epel/beta/7/x86_64/epel-release-7-0.2.noarch.rpm

$ sudo rpm -Uvh epel-release-7-0.2.noarch.rpm

$ ls /etc/yum.repos.d/
CentOS-Base.repo CentOS-Debuginfo.repo CentOS-Sources.repo CentOS-Vault.repo epel.repo epel-testing.repo

Next, let’s install the docker-io package which will install Docker on our host.

$ sudo yum install docker-io

Now that it’s installed, let’s start the Docker daemon.

$ sudo service docker start

[sudo] password for sysadmin:
Redirecting to /bin/systemctl start docker.service

If we want Docker to start at boot, we should also:

$ sudo chkconfig docker on

Note: Forwarding request to ‘systemctl enable docker.service’.
ln -s ‘/usr/lib/systemd/system/docker.service’ ‘/etc/systemd/system/multi-user.target.wants/docker.servic

Now let’s verify that Docker is working. First we’ll need to get the latest centos image.

$ sudo docker pull centos:latest

Next we’ll make sure that we can see the image by running:

$ sudo docker images centos

This should generate some output similar to:

$ sudo docker images centos
REPOSITORY      TAG             IMAGE ID          CREATED             VIRTUAL SIZE
centos          latest          0b443ba039582 hours ago         297.6 MB

Run a simple bash shell to test the image:

$ sudo docker run -i -t centos /bin/bash


If everything is working properly, you’ll get a simple bash prompt. Type exit to continue.

Done! You can either continue with the Docker User Guide or explore and build on the images yourself.


If you have any issues – please report them directly in the CentOS bug tracker.
