1.官網中文安裝參考手冊
https://docs.docker-cn.com/engine/installation/linux/docker-ce/centos/#prerequisites
2、yum安裝gcc相關
1）CentOS7能上外網
2）安裝gcc
[root@localhost ~]# yum -y install gcc3）安裝gcc-c++
[root@localhost ~]# yum -y install gcc-c++
圖像出現如下說明安裝成功！！！
3、如果之前安裝過docker，卸載舊版本
[root@localhost ~]# yum remove docker \
> docker-client \
> docker-client-latest \
> docker-common \
> docker-latest \
> docker-latest-logrotate \
> docker-logrotate \
> docker-engine
4、安裝需要的軟體包
[root@localhost ~]# yum install -y yum-utils device-mapper-persistent-data lvm2
5、設置stable鏡像倉庫
[root@localhost ~]# yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
6、更新yum軟體包索引
[root@localhost ~]# yum makecache fast
7、安裝DOCKER CE
[root@localhost ~]# yum -y install docker-ce
8、啟動docker
[root@localhost ~]# systemctl start docker
9、測試
1）查看docker版本
[root@localhost ~]# docker version
Client:
Version: 18.09.6
API version: 1.39
Go version: go1.10.8
Git commit: 481bc77156
Built: Sat May 4 02:34:58 2019
OS/Arch: linux/amd64
Experimental: false
Server: Docker Engine - Community
Engine:
Version: 18.09.6
API version: 1.39 (minimum version 1.12)
Go version: go1.10.8
Git commit: 481bc77
Built: Sat May 4 02:02:43 2019
OS/Arch: linux/amd64
Experimental: false
[root@localhost ~]#
2）運行 hello-world
[root@localhost ~]# docker run hello-world
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash

[root@localhost ~]#
11、配置鏡像加速
1）、獲取阿裡雲鏡像加速器參考：https://blog.csdn.net/li1325169021/article/details/90770119
[root@localhost ~]# mkdir -p /etc/docker
[root@localhost ~]# vim /etc/docker/daemon.json
在文件中添加如下配置
#阿裡雲鏡像加速器
#網易雲
{"registry-mirrors": ["http://hub-mirror.c.163.com"] }
#阿裡雲
{
"registry-mirrors": ["https://｛自已的編碼｝.mirror.aliyuncs.com"]
}
[root@localhost ~]# systemctl daemon-reload
[root@localhost ~]# systemctl restart docker
2）、配置鏡像加速後重啟docker可能會報錯，參考：https://blog.csdn.net/li1325169021/article/details/90782846
12、卸載
[root@localhost ~]# systemctl stop docker
[root@localhost ~]# yum -y remove docker-ce
[root@localhost ~]# rm -rf /var/lib/docker
