为快速安装部署,目前已提供docker一键安装脚本!

1、检查系统内核

      Docker 要求 CentOS 系统的内核版本高于 3.10 ,查看本页面的前提条件来验证你的CentOS 版本是否支持 Docker 。

通过 uname -r 命令查看你当前的内核版本。

[xcbeyond@docker ~]$ uname -r
3.10.0-327.10.1.el7.x86_64


2、安装Docker

       安装过程及其坎坷,出现了各种问题,并进行记录整个过程,与大家进行分享。2.1 节记录安装过程中出现的各种问题,2.2节整理的是安装成功过程,作为正常安装步骤。

2.1 安装失败

(1)Docker 软件包和依赖包已经包含在默认的 CentOS-Extras 软件源里。执行命令yum install docker

安装过程如下:

[xcbeyond@docker etc]$ sudo yum install docker

It was impossible to connect to the CentOS servers.
This could mean a connectivity issue in your environment, such as the requirement to configure a proxy,
or a transparent proxy that tampers with TLS security, or an incorrect system clock.

Complete!

(2)查看Docker版本。执行命令docker version

[xcbeyond@docker etc]$ docker version
Client:
 Version:         1.13.1
 API version:     1.26
 Package version: 
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

(3)启动Docker。执行命令 service docker start.

[xcbeyond@docker ~]$ sudo service docker start
Redirecting to /bin/systemctl start  docker.service
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

哎,启动失败了。查看下docker状态,如下所示:

[xcbeyond@docker ~]$ systemctl status docker

网上查阅了大量资料,进行配置的修改等,尝试都未能解决,最终决定还是卸载掉,重新换种方式来安装吧。

2.2 安装成功

(1)卸载docker,并配置docker.repo,如下所示:

[xcbeyond@docker run]$ sudo yum remove docker
……
[xcbeyond@docker run]$ sudo yum remove docker-selinux
……
[xcbeyond@docker run]$ sudo vi /etc/yum.repos.d/docker.repo
[dockerrepo]
name=Docker Repository
baseurl=https://yum.dockerproject.org/repo/main/centos/$releasever/
enabled=1
gpgcheck=1
gpgkey=https://yum.dockerproject.org/gpg

(2)安装docker,执行命令yum install docker-engine,如下所示:

(如失败,则可多执行几次便可。安装过程,因需下载安装包,请耐心等待)

[xcbeyond@docker run]$ sudo yum install docker-engine

Complete!

(3)启动docker。执行命令systemctl start docker,如下所示:

[xcbeyond@docker run]$ sudo systemctl start docker

哈哈,大功告成,终于安装成功啦。睡觉喽!


如果在检索镜像时,出现如下类似错误:

[docker@docker xcbeyond]$ docker search redis
Error response from daemon: Get https://index.docker.io/v1/search?q=redis&n=25: x509: certificate signed by unknown authority

 这是由于无法访问国外docker镜像仓库的原因,或者访问比较慢,可修改为国内docker仓库。docker在中国已经有了仓库:https://www.docker-cn.com/registry-mirror,访问速度还不错。

修改方法:

(如果没有daemon.json文件,则创建)

[docker@docker xcbeyond]$ sudo vi /etc/docker/daemon.json
{
   "registry-mirrors": ["https://registry.docker-cn.com"]
}

重启docker,就可以了。

[root@docker docker]# systemctl restart docker
[docker@docker xcbeyond]$ docker search redis
