Ubuntu 14.04 64-bit installation configuration Docker tutorial _docker

Background
a year ago heard of Docker, want to use it to do virtual machine, today finally have the opportunity to put into practice.
I'm using 64-bit Ubuntu 14.04 here. Want to virtual out of 4 devices, install software separately, for cluster testing.
Because the Linux container's Bug,docker is running best on the Linux kernel3.8.

Environmental Inspection and Installation

Take a look at our Ubuntu version command :

Copy Code code as follows:

Cat/etc/issue Ubuntu 14.04.5 LTS \ \l

Look at the kernel again, command:
Uname-r 3.2.0-67-generic

Since the kernel did not meet the requirements, we then upgraded the kernel with the following command:

Copy Code code as follows:

Apt-get Install linux-image-generic-lts-raring Linux-headers-generic-lts-raringsudo

Copy Code code as follows:

Apt-get Install--install-recommends linux-generic-lts-raring xserver-xorg-lts-raring libgl1-mesa-glx-lts-raring

Note: you will need to restart Ubuntu after you upgrade. #重启后检查内核版本.

If the upgrade kernel method mentioned above cannot be upgraded, refer to the following methods:

How Ubuntu 14.04 users install the Kernel 3.14 kernel * (Installation method, download the Deb installation package directly, use the following command)

32-bit System installation command

********

Install Deployment Docker

Update the bottom Source:
vim/etc/apt/sources.list

Use the following Ali:

Deb Http://mirrors.aliyun.com/ubuntu/trusty main restricted universe Multiverse 
Deb http://mirrors.aliyun.com/ Ubuntu/trusty-security main restricted universe Multiverse 
Deb Http://mirrors.aliyun.com/ubuntu/trusty-updates Main restricted universe Multiverse 
Deb http://mirrors.aliyun.com/ubuntu/trusty-proposed main restricted universe Multiverse 
Deb Http://mirrors.aliyun.com/ubuntu/trusty-backports main restricted universe multiverse 
DEB-SRC http://mirrors.aliyun.com/ubuntu/trusty main restricted universe multiverse deb-src 
Mirrors.aliyun.com/ubuntu/trusty-security main restricted universe multiverse 
deb-src http://mirrors.aliyun.com /ubuntu/trusty-updates main restricted universe multiverse 
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-proposed Main restricted Universe multiverse 

Upgrade and install:

Apt-get Update 
apt-get install Docker.io 
service Docker.io restart 

Start

root@linuxidc:~ #docker run-i-T Ubuntu/bin/bash cannot connect to the Docker
daemon. Is ' docker-d ' running to this host?
root@iz28ikebrg6z:~# docker-d

The following error occurred:
root@iz28ikebrg6z:~# docker-d
Could not find a free IP address range for interface ' Docker0 '. Please configure it address manually and run ' Docker-b Docker0 '

And then we just need to type:

Copy Code code as follows:

root@linuxidc:~ #sudo Route del-net 172.16.0.0 netmask 255.240.0.0

Note here, after each reboot, execute the above command and make the subnet mask.

Then perform the docker-d start OK instructions Docker the installation is complete and start successfully.

Creating Containers and using

Docker pull Ubuntu #此处是从官网拉取名为ubuntu的image 
Docker images view pull down the mirrors, note: Repository:tag behind the boot use 
docker run-i-T Ubuntu:latest/bin/bash #创建一个容器,-T is a temporary terminal. 
Docker Run-dit [Container_name or container_id] #交互式启动 
run-d ubuntu:latest/bin/bash #后台启动. 
//tips: When exiting, use [Ctrl + D] or exit to end the Docker current thread and end the container.

//You can use [Ctrl + P][ctrl + Q] to exit without terminating the container to run 
Docker exec-it [Container_name or container_id]/bin/bash #会在指定容器中执行指定命令 。 
Docker rename Container_name new_name #给容器重命名 
Docker rm container_id #删除容器 
Docker Accach Container_name # Enter a background container 
run-d-P 50001:22 ubuntu:latest/bin/bash #创建端口映射从50001到容器的22端口, and then login to install SSH
