Centos Docker 安裝 並 配置鏡像加速

 

一、根據官網文檔提示：

https://docs.docker.com/install/

二、實際安裝操作

centos：

https://docs.docker.com/install/linux/docker-ce/centos/ 可能很慢

卸載舊版本：

較舊的Docker版本稱爲docker或docker-engine。如果已安裝這些程序，請卸載它們以及相關的依賴項。

$ sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

安裝所需的軟件包。yum-utils提供了yum-config-manager ，並且devicemapper存儲驅動程序需要device-mapper-persistent-data和lvm2 

sudo yum install -y yum-utils \
  device-mapper-persistent-data \
  lvm2

使用以下命令來設置穩定的存儲庫。 

sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

安裝最新版本的Docker Engine-Community和containerd 

$ sudo yum install docker-ce docker-ce-cli containerd.io

這一步可能失敗，網絡太慢，嘗試了3次，放棄了......

配置本地yum源來安裝docker，

清華大學yum源  https://mirrors.cnnic.cn/

$ mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak
$ vim /etc/yum.repos.d/CentOS-Base.repo
​
​​​# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

$ yum clean all     # 清除系統所有的yum緩存
$ yum makecache     # 生成yum緩存

使用yum直接安裝，簡單粗暴： 

yum install docker -y

[root@cloud-container other]# systemctl start docker
[root@cloud-container other]# docker -v
Docker version 1.13.1, build cccb291/1.13.1

 配置國內docker鏡像源

# 添加 網易鏡像源​ 把下面的內容添加到文件
vi /etc/docker/daemon.json

{​
    "registry-mirrors": [
        "http://hub-mirror.c.163.com"
    ]
}

重啓服務
 systemctl restart docker​
