CentOS 8 安装docker

CentOS 8 安装docker

一、卸载旧版本

yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-selinux \
                  docker-engine-selinux \
                  docker-engine

二、安装依赖包和必要的一些系统工具

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

三、配置yum稳定镜像源

因为国内网络原因，推荐使用阿里云提供的Docker CE 镜像源站！

sudo yum-config-manager --add-repo http:``//mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

四、安装Docker

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

安装过程中可能会出现的问题

[root@localhost ~]# sudo yum install docker-ce docker-ce-cli containerd.io
Docker CE Stable - x86_64                                                                                                               1.6 kB/s | 3.5 kB     00:02

(try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

解决办法：

yum erase podman buildah

五、关闭防火墙并禁用防火墙

# 查看状态
systemctl status firewalld.service

# 打开防火墙
systemctl start firewalld.service

# 关闭防火墙
systemctl stop firewalld.service

# 开启防火墙
systemctl enable firewalld.service

# 禁用防火墙
systemctl disable firewalld.service

六、设置docker开机自启

systemctl enable docker

七、手动设定docker镜像源

vim /etc/docker/daemon.json

# 配置以下镜像源
{
  "registry-mirrors":["http://hub-mirror.c.163.com","https://docker.mirrors.ustc.edu.cn"]
}

推荐几个镜像源：

​ 网易 http://hub-mirror.c.163.com

​ 中国科技大学 https://docker.mirrors.ustc.edu.cn

​ 阿里云 https://pee6w651.mirror.aliyuncs.com

修改完之后，需要重新启动Docker。（当修改配置文件时候都需要进行重启服务）

systemctl daemon-reload    # 重新载入 systemd，扫描新的或有变动的单元
systemctl restart docker          # 重新启动Docker服务

八、最后

至此docker安装完成

执行docker run hello-world 命令，测试docke安装是否正常。
