安装需要的软件包

[root@localhost ~]# yum install -y yum-utils device-mapper-persistent-data lvm2


设置stable镜像仓库（采用方式二）

  • 方式一（大坑）执行命令后报错，这种方式是错误的

[root@localhost ~]# yum-config-manager —add-repo https://download.docker.com/linux/centos/docker-ce.repo
1
报错：
1 [Errno 14] curl#35 - TCP connection reset by peer

2 [Errno 12] curl#35 - Timeout

  • 方式二

[root@localhost ~]# yum-config-manager —add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

更新yum软件包索引

[root@localhost ~]# yum makecache fast

安装DOCKER CE

[root@localhost ~]# yum -y install docker-ce
启动docker
[root@localhost ~]# systemctl start docker

查看docker版本

[root@localhost ~]# docker version

配置镜像加速

1）、获取阿里云镜像加速器参考：https://blog.csdn.net/li1325169021/article/details/90770119
[root@localhost ~]# vim /etc/docker/daemon.json
内容如下：

  1. {
  2.   "registry-mirrors": ["http://hub-mirror.c.163.com"]
  3. }

[root@localhost ~]# systemctl daemon-reload
[root@localhost ~]# systemctl restart docker

查看docker服务的状态

systemctl status docker

设置docker开机启动服务

systemctl enable docker

12、卸载

[root@localhost ~]# systemctl stop docker
[root@localhost ~]# yum -y remove docker-ce
[root@localhost ~]# rm -rf /var/lib/docker
